I would like to express my gratitude for your cooperation and support of Japan Broadcasting Corporation (NHK).

NHK Science & Technology Research Laboratories (STRL) was established in Setagaya Ward, Tokyo, in 1930, fi ve years after the start of radio broadcasting in Japan, as a center for broadcasting technology research and embarked on research into TV broadcasting. Since then, STRL has continuously been at the forefront of cutting-edge broadcasting technologies and contributed to the development of broadcasting technology both in Japan and around the world, through its pioneering efforts on satellite broadcasting, HDTV, and digital broadcasting services.

To implement broadcasting and services of the highest standard by 2020, the year of the Tokyo Olympic and Paralympic Games, NHK is actively working on the creation of services that can off er viewers new values. The test broadcasting over satellite channels of Super Hi-Vision, the next generation of broadcasting delivering a strong sense of presence, on which STRL began R&D in 1995, is scheduled to start on August 1 of this year. This will be an important step toward the launch of broadcasting to the public in 2018.

Furthermore, STRL is looking ahead to the media environment in 20 years' time, when Super Hi-Vision is expected to be widely used. We plan to focus on research on the technologies to deliver a more enriched and extensive content to all people including the elderly and disabled through diverse channels using broadcasting and the Internet, as well as research on new broadcasting services such as 3D television.

This year's NHK STRL Open House marks its 70th anniversary. It introduces you to 27 of our latest research achievements, featuring fi ve technologies: the ever-evolving "Super Hi-Vision," "Internet utilization technology" to provide new broadcasting services, "smart production" technology for producing content by utilizing user-friendly technologies, "3D television" for providing natural 3D images, and "Future devices" that support advanced broadcasting systems. We are making progress toward our goal of creating broadcasting and services that open up new possibilities.

I sincerely hope that you will continue to support our activities in the future.

Exhibit outlining 8K HDR live program production

※ 1 HLG (Hybrid Log-Gamma): Major parameters for HLG are specifi ed in ARIB STD-B67, a domestic standard published in July 2015. Domestic standards of video coding and multiplexing formats for Super Hi-Vision broadcasting also support the HLG system.

※ 2 SDR (Standard Dynamic Range): The standard dynamic range specifi ed in Recommendation ITU-R BT.709.

●The 8K HDR liquid crystal display compatible with HLG was jointly developed with Sharp Corporation.

We will establish a method of HDR 8K video production using the HLG system and contribute to HDR program production for 8K broadcasting.

● Hybrid Log-Gamma (HLG)※1 system suitable for broadcastingThe HLG system is an HDR television standard jointly developed by NHK and BBC (British Broadcasting Corporation). It is suitable for TV broadcasting because it is highly compatible with existing TV infrastructure (SDR)※2 and capable of handling images with a much wider range of contrast.

● 8K program production equipment for making HDR broadcasting a realityWe have developed 8K cameras supporting the HLG system and an 8K display with high brightness and a high contrast ratio. Conventional devices can be used for other production equipment.

● HDR live video productionThe HLG format is a specifi cation for conversion from light to electrical signals during the capture of images. It allows easy video adjustment because it can handle video signals in the same way as conventional program production and is therefore suitable for 8K HDR live program production, in which multiple cameras are switched back and forth to capture images. It also allows the effective utilization of existing content and equipment because of its compatibility with SDR.

We have developed an HDR television technology that expands the range of brightness that can be shown in TV images, with the aim of using it for 8K Super Hi-Vision broadcasting. This exhibit presents live program production using 8K cameras, an 8K display and an 8K program production system that support the HDR television standard.

While continuing with the development of production equipment for full-featured 8K, we will build and verify a production environment using such equipment. We will also implement the 120-Hz timecode into a system and study the practicality of a synchronization system using IP technology.

●The compression recorder is jointly developed with Tokyo Electron Device Ltd.

●The 17-inch liquid crystal display is jointly developed with Japan Display Inc.

※ 1 Full-featured 8K: A state-of-the-art format providing a color gamut that covers most real surface colors with 8K full resolution (33 megapixels each for RGB), 120-Hz frame frequency, a wide color gamut, 12-bit depths, HDR (high dynamic range), and a 22.2 multichannel sound system.

※ 2 Timecode: Time information label added to each video frame.※ 3 U-SDI (Ultrahigh-definition Signal/Data Interface): An interface that can transmit all kind of UHDTV video signals over a single cable.※ 4 PTP (Precision Time Protocol): An IEEE 1588 standard protocol for precisely synchronizing clocks over an IP network.

● 8K production equipment for full-featured 8KWe have developed 8K devices which include a compression recorder using a removable memory package, a four-input four-output signal router, a waveform monitor, a timecode separator and a 17-inch liquid crystal display.

● 120-Hz frame frequency timecode and sync signal over IPWe are working on the standardization of a new timecode supporting 120-Hz frame frequency for full-featured 8K. The timecode can also be read by existing devices because of its compatibility with the conventional timecode supporting 60-Hz frame frequency. We have also adopted a PTP※4 synchronization system that can coordinate clocks precisely using IP technology.

We are developing production equipment for full-featured 8K Super Hi-Vision※1. This exhibit demonstrates an example of a production system using equipment supporting 120-Hz frame frequency, which we have developed while considering compatibility with HDTV production systems and the conventional timecode※2.

※ 1 Single-chip imaging: A method to obtain RGB color images (video) using a single image sensor.※ 2 Wavelength division multiplexing: A technology to transmit multiple optical signals with different wavelengths over a single optical fiber.※ 3 U-SDI (Ultrahigh-definition Signal/Data Interface): An interface standardized in Recommendation ITU-R BT.2077 and ARIB STD-B58, etc., that can

handle the uncompressed transmission of full-resolution, 120 Hz frame frequency 8K video over a single cable.

We aim to make the camera system operational at 120 Hz frame frequency to enable the shooting of full-specifi cation 8K video. We will also continue R&D for further downsizing of the unit and to improve the image quality.

●Full-resolution 8K shooting with a single-chip cameraA single-chip imaging※1 that does not need an optical color separation prism is suitable for a compact camera. By using a 133-megapixel image sensor, we have achieved the first single-chip camera that can capture full-resolution 8K video. The camera can also use a wide variety of cinema and 35 mm full-frame lenses because the optical format of the 133-megapixel image sensor is the same as 35 mm full-frame.

●Lightweight camera headWe have developed a camera head weighing only 6 kg, less than one-seventh of a conventional three-chip full-resolution 8K camera. Using a compact, built-in wavelength division multiplexing※2 signal transmission device, it can transmit 100 Gbps output video signals over a single HDTV hybrid camera cable.

●Compact, multifunction camera control unitWe have developed a camera control unit (CCU) with many capabilities such as real-time processing of 100 Gbps high-speed signals, correction of lateral chromatic aberration of the lens, and HDR (high dynamic range) capturing. The CCU outputs a U-SDI signal※3 compliant with international standards.

We are conducting research to achieve a practical 8K Super Hi-Vision camera. We have developed a portable camera system that can capture full-resolution (RGB 4:4:4) 8K video with 33 megapixels each for red (R), green (G) and blue (B) by using a single image sensor.

We aim to improve the characteristics of the holographic recording prototype drive as well as further increase the density and data transfer rate for its practical use as 8K archival equipment.

●This research is jointly being conducted with Hitachi, Ltd. and Hitachi-LG Data Storage, Inc.

※ Photopolymer: A photosensitive resin.

● Reproduction of compressed 8K videoCompressed 8K video signals can be recorded and reproduced in a holographic memory. We have integrated laser and optical parts and a disk medium into a single holographic memory prototype drive package for stable recording and reproduction.

● Compensation for optical distortion using wavefront controlWhile the photopolymer※ material used for the disk is expected to retain recorded data for more than 50 years, it causes optical distortion due to vibrations and changes in temperature and volume of the recording medium. To compensate for the distortion, we have developed a technology to control the wavefront of the reference beam, enabling accurate data reproduction.

● Increased recording density by shortening the laser beam wavelengthThe recording density is inversely proportional to the square of the laser beam wavelength. Instead of the green laser beam (with a wavelength of 532 nm) that we previously used, we are using a blue-violet laser beam (with a wavelength of 405 nm) and a suitable material for the recording medium. This has increased the recording density.

We are conducting research on high-density holographic memory for the long-term archiving of 8K Super Hi-Vision video. This exhibit displays a holographic recording prototype drive equipped with a technology to improve the quality of reproduced data and presents a reproduced video of compressed 8K signals recorded on its disk medium.

● Upmixing preprocessorWe have developed software to generate 22.2 ch sound from 2 ch or 5.1 ch sound material. This has enabled the easy utilization of existing sound material for 22.2 ch sound production.

● Improved functionality of 3D reverberatorA reverberator is a device that adds the reverberation sound heard in places such as studios and halls to sound material. With our new technology to extend the reverberation time while maintaining the features of the captured 3D reverberation sound, we have doubled the variable range of the reverberation time, which is important for adjustment of the spatial impression.

● Loudness meter for evaluation of program soundWe have developed a loudness meter for 22.2 ch sound that is compliant with the international and domestic standards※, which were revised last year. In addition to being able to measure the subjective perception of how loud a sound appears to the human ear (i.e., a loudness level), the device is equipped with an "ultra-reality" meter (Poster Exhibit A-P1) that can assess and quantify spatial impressions such as the sense of reality, spaciousness, and evocative qualities.

We are researching technologies to produce high-quality 22.2 multichannel sound (22.2 ch sound) more easily in preparation for 8K broadcasting. This exhibit displays a new upmixing preprocessor as well as a 3D reverberator and loudness meter with enhanced functions.

We will conduct experiments in cooperation with relevant institutions toward realizing the practical cable TV retransmission of Super Hi-Vision satellite broadcasting.

※ 1 MMT (MPEG Media Transport): International standard multiplexing scheme supporting media transport through various transmission paths.※ 2 TLV (Type Length Value): A transmission signal format to efficiently transmit IP packets (variable-length packets) over broadcasting channels.

● 8K retransmission on existing cable TVSuper Hi-Vision satellite broadcasting signals received at a cable TV station are divided into multiple channels for transmission and then combined correctly at homes. In this way, they can be delivered to subscribers without any changes to the existing cable TV transmission paths. Here we demonstrate how 8K signals in the MMT※1 and TLV※2 formats, which will be used for 8K test broadcasting, are received at an actual cable TV station via satellite, retransmitted, and then demodulated and combined for reproduction at the exhibition site.

● Channel bonding technology compliant with domestic and international standardsWe standardized the transmission scheme using multiple channels, which led to a domestic standard being issued by Japan Cable Television Engineering Association in 2015. Also, ITU-T published international recommendations for specifi cations consistent with the domestic standard.

We are studying ways to distribute Super Hi-Vision (8K/4K) satellite broadcasting to homes on cable TV. This exhibit presents a system for retransmitting 8K satellite signals on cable TV by using a channel bonding technology that is compliant with both domestic and international standards.

● Increased effi ciency by interlayer prediction using super-resolution reconstructionThis system encodes and transmits low-resolution video reduced from the original high-resolution video. It also super-resolves the locally-decoded low-resolution video in different reconstruction modes at the transmission side and transmits the block-wise optimal mode selection as supplementary data. This system can achieve higher compression ratio than conventional scalable video coding because it can generate high-resolution video with only a small amount of supplementary data for super-resolution reconstruction.

● Hardware-oriented computation algorithmsTaking hardware implementation into consideration, we fi gured out appropriate computation methods for super-resolution reconstruction and optimization to decide the best super-resolution mode. We also employed a parallel-series architecture with simple image processing templates to facilitate integrated circuit implementation in anticipation of installation in receivers.

● Scalable transmission schemeThis system allows viewers to view 4K video as is with ordinary TV sets. It can also provide 8K video by adding supplementary data, the amount of which is about 3 to 10% of that of the 4K video stream. The supplementary data contains video feature values of each frame as well as switching information for super-resolution reconstruction. The feature values are used to synchronize decoded video and supplementary data.

We will conduct demonstration experiments on an overall system including transmission systems such as channel coding, modulation and demodulation processes and also contribute to future video coding standardization.

● This research is partially being performed under the auspices of the "Research and Development of Technology

Encouraging Effective Utilization of Frequency for Ultra High Defi nition Satellite and Terrestrial Broadcasting System"

program, which is funded by the Ministry of Internal Affairs and Communications.

※ 1 Super-resolution reconstruction: A technique to enhance the resolution of an image by supplementing edges and fi ne-grained texture.※ 2 Interlayer prediction: A technique to predict a high-resolution image from a low-resolution image.

We are conducting research into a high-efficiency video coding technique for the simultaneous service of video with different resolutions. The use of super-resolution reconstruction※1 technique enables accurate 4K-to-8K interlayer prediction※2.

※ 1 LDPC (Low-Density Parity Check) codes: Block codes defi ned by low-density parity-check matrices.※ 2 SFN (Single-Frequency Network): A broadcasting network confi guration where multiple different stations transmit radio waves on the same

channel to form a coverage area.※ 3 Space-time coding: A method to convert a single signal to multiple different signals by simple processing. It allows the receiver to receive signals

by making full use of radio waves from multiple transmitting stations.

● Increasing frequency usage effi ciency compared with the current digital terrestrial broadcastingWe have achieved more effi cient frequency usage by using a new signal structure that minimizes the guard band, guard interval, etc.

● Error-correcting codes with superior decoding characteristicsWe are using LDPC codes※1 for error correction, which enable efficient decoding even for long codes, by employing parallel processing and other means.This has allowed us to make significant improvements in the error correction performance compared with the convolutional codes used for the current digital terrestrial broadcasting.

● Study on a more stable single-frequency network (SFN)Current terrestrial digital broadcasting utilizes an SFN※2 to make efficient use of limited frequencies. To form a stable SFN for next-generation terrestrial broadcasting even when using high-order modulation, we are verifying the effectiveness of an application of space-time coding※3 through fi eld experiments.

We will conduct experiments using various channels including the Internet widely used today and the future broadband to demonstrate the advanced services for 8K broadcasting.

※ 1 MMT (MPEG Media Transport): An ISO/IEC standard media transport protocol for media delivery in heterogeneous environments. MMT-based broadcasting systems are specifi ed in Recommendation ITU-R BT. 2074. MMT is also specifi ed as an element of the management and protocol layer of ATSC 3.0, the next-generation terrestrial broadcasting standard under development in the U.S.

※ 2 Multicast technology: A technology to effi ciently send data to multiple terminals simultaneously over an IP network.※ 3 Baseband transmission technology: A transmission scheme to transmit digital broadcasting using digital signals without modulation or

demodulation, making it suitable for optical transmission.

● Shared receiver for broadcasting and broadbandWe are aiming to realize a shared receiver for broadcasting and broadband that allows viewers to select programs without considering their delivery channels. MMT has already been adopted as the media transport protocol for Super Hi-Vision (8K/4K) satellite broadcasting, for which test broadcasting will begin in 2016. When MMT is used for cable TV as well as for delivery in the Internet, most parts of the receiver can be shared.

●MMT-based advanced servicesMMT can transmit video, audio and various information for advanced services through broadcasting as well as broadband in the same way. It enables providing scene commentaries in broadcasting as the multiplexed form. It also enables providing multi-angle videos that are presented in synchronization with the broadcasting program even though they are separately delivered in broadband.

● 8K multichannel delivery technologiesFuture high-speed broadband will enable the transmission of multichannel 8K programs. We have developed 8K multichannel delivery technologies using multicast technology※2 and baseband transmission technology※3.

We are continuing research into 8K Super Hi-Vision delivery technology using MMT※1. This exhibit presents a shared receiver that can receive programs transmitted through either broadcasting or broadband. It also presents MMT-based advanced services and 8K multichannel delivery technology using future broadband such as optical fi bers supporting up to 10 Gbps transmission.

●Millimeter-wave FPU for high-speed transmissionThis FPU can provide a transmission rate in excess of 200 Mbps by using the 42-GHz band, which provides a wide bandwidth. It achieves high-speed transmission by using wideband radio transmission technology exploitting the 125 MHz bandwidth and dual-polarized MIMO※2 technology.

●Microwave FPU for long-distance transmissionThis FPU, which uses the same channels as a 6- to 7-GHz-band Hi-Vision FPU, enables long-distance 8K relays. It achieves a transmission rate of approximately 200 Mbps by using ultra-multilevel OFDM※3 technology and dual-polarized MIMO technology.

● Antenna for microwave FPUsWe have developed a portable parabolic antenna, a transmission antenna for helicopters, and a high-gain receiving antenna mounted on a rotator to support the dual-polarized MIMO technology used for microwave FPUs.

● Transmission technologies for mobile relay FPUsWe are researching transmission technologies using the 1.2-GHz/2.3-GHz band so that 8K video can be transmitted without interruption in mobile relays such as those used to broadcast road races. We have prototyped 4×4 MIMO-OFDM transmission devices that can change transmit and receive beams adaptively according to the propagation channel.

We are developing wireless transmission equipment (FPU)※1 for live broadcasts of 8K Super Hi-Vision.

● Highly precise synchronization of broadcasts and Internet content by HybridcastA feature allowing the synchronization of broadcast and Internet content, which was specifi ed in the Hybridcast Technical Specifications ver2.0※2, enables applications to acquire broadcast reference clocks. Our latest technology to coordinate the various clocks of various media components can accurately synchronize and visualize UTC※3-based Internet content along with the broadcast program.

● Live tracking data for more enriched user experienceThe use of Hybridcast's synchronization function and live tracking data delivered over the Internet brings new user experience. For example, the motion and detailed data of players not being covered in the broadcast video can be visualized using animation corresponding to the live soccer game footage.

● Delivery of live and real-time data by cloud serversReal-time tracking data produced at the game fi eld can be directly delivered to receivers over the Internet through cloud servers. The results of distribution tests show that synchronized presentation of various information with broadcast live footage can be achieved well.

Toward higher functional Hybridcast, we are researching technologies to synchronize Internet delivered content with broadcast programs. This exhibit presents an example of how we can offer multifaceted viewing experiences of live sports coverage. You will see how the synchronized presentation makes it more attractive by displaying various information along with the broadcast program through the use of tracking data※1.

MPEG-DASH (MPEG Dynamic Adaptive Streaming over HTTP).

● Real-time acquisition of reception situationWe have developed a mechanism for the distributor side to immediately grasp the reception situation based on the communication line speed and other data measured at individual viewing terminals. This enables the adaptive switching of delivery paths and the adaptive control of transmission rates to allow smooth video reproduction for each terminal.

● Adaptive delivery path control techniquesThese are techniques to reduce network congestion and provide a stable distribution by changing the delivery path for each viewing terminal according to the reception situation and by using a multicast distribution※2 depending on the scale of viewers.

● Adaptive control techniques for video distribution transmission ratesCommon adaptive streaming technologies※3 produce multiple video fi les for fi xed transmission rates so that each viewing terminal can select an appropriate transmission rate according to its screen size and communication line speed. In addition, our latest technique allows encoders on the distributor side to change transmission rates precisely according to the reception situation. This can reduce sudden variations in the reproduced image quality.

We are conducting research into stable delivery techniques for Internet video services. This exhibit presents distribution technologies for smooth video reproduction in diverse viewing styles that include various devices (e.g., TV, PC, smartphone), different places (home vs outside the home), and different viewing timings (real-time viewing vs time-shift viewing※1).

● Distinguishing text from graphicsIt is diffi cult to distinguish text from nearby graphics with a similar color or size. The system identifi es irregular lines and components that are characteristic to Japanese characters and distinguishes them from other graphics.

To make it easier for producers to find the desired footage, we are working on a system to automatically generate metadata for video materials. Our exhibit illustrates how we can detect text from signboards and nameplates that are included in videos by chance.

The system analyzes incoming codes and inserts relevant words into the template to generate appropriate sign language animations.

● Compatible with weather warningsWe have increased the speed of data processing to present urgent weather warnings with sign language animations in addition to regular weather information. We are also now able to present local warnings at the municipal level.

● Presenting multiple stimulation to multiple fi ngersThe device presents the shape of a three-dimensional object as three stimulation points on the skin of the thumb and two fi ngers.

● Recreating the sense of "grasping" an objectThe device estimates the location and angle of the hand as it tries to "grasp" an object and controls the stimulation so that the fi ngertips are always "on" the surface, virtually recreating its shape.

To make "tactile" or touchable television a reality, we are continuing our research on technology to convey the shapes and fi rmness of physical objects such as works of art.

● Calibration technique for multiple pan-tilt camerasTo create high-quality multi-viewpoint video with accurate CG compositing, we propose an accurate calibration technique that analyses images of multiple calibration patterns from multiple cameras. We have also developed a calibration method that makes it easy to obtain the positions and orientations of multiple cameras deployed for shooting in the fi eld.

● High-precision object tracking using multi-viewpoint videoWe can track objects robustly under almost any conditions by using the positional relationships of cameras along with 3D motion prediction to calculate the precise position of a ball or a player in motion. We can then superimpose data such as speed or trajectory onto the video by analyzing the object tracking data.

We are working on new technology combining multi-viewpoint video※1 with computer graphics to provide an entirely new sports viewing experience.

We will continue our research on both capturing and displaying technologies and improve the quality of 3D image. Our goal is to create a practicable 3D television.

As part of our research on integral 3D technology that will allow viewers to see convincing three-dimensional images without special glasses, we have created an improved 3D displaying device by combining multiple projectors.

We will continue to pursue a wide range of research, from fundamental technology to device development, in an attempt to dramatically improve broadcast cameras.

●The research on back-illuminated small-size image sensors is jointly being conducted with Shizuoka University.

● The research on pixel-parallel processing three-dimensional integrated imaging devices is jointly being conducted with

the University of Tokyo.

●The research on organic image sensors is jointly being conducted with Kochi University of Technology.

● Back-illuminated small-size image sensorWe have prototyped a novel image sensor for 8K Super Hi-Vision with 33 million pixels of size 1.1μm. The sensor size is equivalent to 2/3 optical inch and the back-illuminated pixel structure contributes to its sensitivity and speed. Newly developed high-speed A/D conversion circuits are integrated, enabling a high frame rate of 240 Hz.

● Pixel-parallel processing three-dimensional integrated imaging deviceThe signal processing circuit for each pixel is arranged just beneath the photodetector, allowing every pixel to output simultaneously. This means we can increase the pixel count and still achieve a high frame rate. We have demonstrated its validity with our latest 128 × 96-pixel prototype.

● Solid-state image sensor overlaid with photoelectric conversion layer and organic image sensor (Poster Exhibits E-P1, P2)

Photodetectors convert light into electrical signals and are usually made from silicon. We believe that substituting silicon with selenium, a compound semiconductor, or an organic material will improve the sensitivity or color separation performance of image sensors. The poster exhibits explain our latest achievements.

We are refi ning our imaging devices to improve current 8K Super Hi-Vision cameras and help develop future three-dimensional cameras. This exhibit introduces our latest achievements in imaging devices.

We will continue to enhance our OLED technology to reduce power consumption while boosting lifetime. We will also work on improving solution-processed oxide TFTs and driving technologies.

●The research on inverted OLEDs is jointly being conducted with Nippon Shokubai Co., Ltd.

※ 1 TFT: Thin-Film Transistor※ 2 OLED: Organic Light-Emitting Device. Uses electroluminescence, which is the emission of light in response to electric current.

In order to create lightweight, ultrathin 8K displays, we are working on elemental technologies to extend their lifetime, increase the screen size, and improve video image quality.

● Solution-processed oxide TFT※1 technology for larger displays (Poster Exhibit E-P3)We have developed a novel fabrication technology for producing solution-processed oxide TFTs at a low temperature that are suitable for application as fi lm substrates and for creating larger displays. Applying this technology to pixel circuit formation is expected to enable cost-effective fabrication of large-area sheet-type displays.

● Inverted OLED※2 for longer lifetime (Poster Exhibit E-P4)We have created a new device called an inverted OLED, which has an inverted structure compared with a conventional OLED. Using a material that is less vulnerable to oxygen and moisture is expected to help extend the lifetime of sheet-type displays.

● Controlling light emission to improve image quality and lifetime (Poster Exhibit E-P5)To solve the problem of motion blur of OLED displays, we have developed a driving technology which controls the light emission period line by line. Longer lifetime as well as an improvement in video quality can be expected as a result of suppressing instantaneous luminance changes.

In order to realize a high-speed magnetic nanowire memory, we will investigate the best magnetic material to drive magnetic domains at a high speed, and upgrade the high-speed prototype performance evaluation tool utilizing gigahertz band signal processors.

※ 1 Magnetic nanowires are ferromagnetic materials formed into wires approximately 100 nm wide, 10-40 nm thick, and 10-100 μm long.※ 2 A magnetic domain is a nanoscopic region in a magnetic material where the magnetic moments are aligned in one direction. It is a unit where

data are stored.

● Potential for a high-speed memory device without mechanically moving partsThe basic structure of a magnetic nanowire memory is similar to placing a pair of recording and reproduction heads on every data track in a hard disk medium, but with the nanowire acting as the data track. Magnetic domains※2 in a nanowire move forward at a high speed when spin-polarized electron fl ow is supplied along the nanowire. so, if we can activate the same mechanism in every magnetic nanowire simultaneously, we will be able to create a high-speed memory device without any mechanically moving parts.

● Evaluation of recording, storage, and reproduction performanceWe have prototyped a device to evaluate the recording and reproduction performance of magnetic nanowire memories. We have carefully attached a pair of recording and reproduction heads which are used in conventional hard disk drives onto a magnetic nanowire and applied pulsed currents along the nanowire length direction, thereby demonstrating how the recording head forms magnetic domains (=recording), which are then pushed forward at a high speed by the electron fl ow (=information storage) and are fi nally detected at the reproduction head (=reproduction).

We are proposing a magnetic nanowire※1 memory architechure for a future high-speed recording device. On exhibit is our prototype performance evaluation tool. We explain how magnetic nanowires are used to record, store, and reproduce information.

To improve the sensitivity of 8K cameras, we are working on solid-state image sensors that are overlaid with photoelectric conversion layers (low-voltage carrier multiplication fi lms) that can multiply signal charges. We have made several improvements including further fl attening of the fi lm surface and reducing the dark current.

We are developing an organic image sensor using transparent readout circuits overlaid with organic fi lms that convert each of the three primary colors of light into electrical signals. The principles of organic image sensors and the latest achievements in our research are illustrated in our poster exhibit.

The aim of our research on solution-processed oxide TFTs is to create large, ultrathin, sheet-type displays using easier manufacturing process. We have succeeded in fabrication of solution-processed oxide TFTs at a low temperature while improving their performance.

Film substrates tend to allow oxygen and moisture to pass through them. We are researching the use of an inverted OLED to extend the lifetime of displays even on a film substrate and create large-scale sheet-type displays. Come and see how our inverted OLED works and how we have improved its properties.

We have developed a panel-driving technology to improve both the video image quality and the lifetime of sheet-type OLED displays. Controlling the light emission periods line by line according to picture patterns, an improvement in motion blur as well as longer lifetime will be realized.

●World's fi rst direct satellite broadcasting services for homesNHK began research on the main unit of a broadcasting satellite and a home receiver in 1966 and started the world’s first direct satellite broadcasting in 1984. This has enabled TV broadcasts to be received at homes throughout Japan, even in mountainous regions and remote islands, and established a foundation for the satellite broadcasting services currently used by people around the world.

● Hi-Vision, the leader of world broadcasting technologiesWe began basic research on a high-quality television system in 1964 and conducted a wide range of R&D from psychophysical experiments, including investigating the relationship between the angle of view and the sense of reality, to system development. In 1989, we started the world's fi rst Hi-Vision broadcasting trials, which formed the basis of the broadcasting standard of 1,125 scanning lines with a 16:9 aspect ratio. With the system of 1,125 scanning lines adopted as a unifi ed worldwide studio standard in 2000, Hi-Vision has become widespread throughout the world.

● Emergency warning broadcasting system to ensure safety and securityIn 1985, we achieved emergency warning broadcasting, which automatically turns on televisions or radios and provides information to the public in the case of a large-scale earthquake or tsunami. Emergency warning broadcasting has been integrated into the technical standards of international satellite and terrestrial broadcasting during digital TV standardization. It is still in use today, supporting disaster broadcasting.

IEEE※ milestones recognize signifi cant international technical achievements that were put into practice at least 25 years ago in the fi elds of electrical and electronic technology. In addition to the milestone for direct satellite broadcasting services awarded in 2011, this exhibit presents our recent awards for Hi-Vision and emergency warning broadcasting system.

Expectations of Future Broadcasting Boosted by Video, Media, and Technology

Kiyoharu AIZAWA, Ph.DProfessor, The University of Tokyo

How people choose between television and Internet videoThe use of video services ––now and the future

Maki SHIGEMORIHead of Public Opinion Research Division, NHK Broadcasting Culture Research Institute

The greatest mission of broadcasting is to produce and deliver socially relevant content to its audience. However, in light of

recent developments in media technology and the media environment, the ability of broadcasting to deliver video contents to

the wider public seems to be at a turning point. Broadcast technology has constantly pursued better quality, higher resolution,

and a greater sense of reality in video. 340,000-pixel standard-defi nition video grew into 2-megapixel Hi-Vision, and now we

are ready to welcome Super Hi-Vision boasting 33 megapixels. Broadcasting is a stable and secure way to deliver video once a

system is up and running, but the technology and media landscape are evolving faster than ever.

Smartphones may well be the single greatest infl uence on how people gather and consume information. They are now much

more accessible for average users than televisions and laptops. They are used as displays to stream and watch digital contents

and cameras to capture photos/videos as well.

Social media including Facebook, Twitter, and Instagram started to introduce video to their services recently. Facebook

reported that their number of daily video views reached 8 billion as of November 2015. One can imagine the impact a video clip

can have when it is “liked” and shared on their platform, and now we are seeing a new type of media emerging called “distributed

media” that uses these social platforms to disseminate content.

With media technology advancing at a fast pace, what do we foresee for the future of broadcasting? Various technologies

that had hitherto developed independently are gaining greater presence in core areas of broadcasting technology, such as

imaging, transmission, and displays. Looking ahead, one example will be the potential of VR (virtual reality) to become the next

new mode of display.

This talk aims to examine how broadcasting may evolve in these changing times and what it needs to focus on as its essential

values.

For young people today, where video contents come from is irrelevant, i.e., whether they are televised or distributed

via the Internet. They fi nd images to their liking skillfully and effortlessly. This behavior has been enabled by advances in

the video viewing environment including the capability of Internet transmission and the capacity of hard disk drives for

recording the contents as well as the spread of the video distribution market.

In particular, the Internet is awash with different genres of videos of various lengths, ranging from movies and TV

programs produced by professional companies to so-called UGCs (user-generated contents) posted by ordinary users.

Regarding paid contents, overseas OTT (over-the-top) service providers such as Netflix and Amazon are entering the

Japanese market one after another, resulting in an increase in the number of original contents. Domestic broadcasters and

other business operators are also launching content delivery services, contributing to the rapid improvement of the viewing

environment for both real-time contents and VOD (video on demand). This is the background of the NHK Broadcasting

Culture Research Institute’s survey, “The Japanese and Television - 2015,” which revealed that not only is people’s TV

viewing time becoming shorter but also their interest in television is waning.

How, then, do Japanese people obtain and enjoy video contents? The Institute has been regularly conducting social

surveys about television and viewers. This talk examines the changes over time in the viewing status of television and online

videos, and in people’s attitudes to television and TV programs, based on survey data. It introduces the video viewing

behavior in detail from the results of a web survey, such as under what circumstances people watch videos. A qualitative

research also clarifi es how young people come in contact with web contents, including the difference in the circumstances

under which television and the Internet are chosen. These fi ndings will help predict future trends of video viewing.

NHK STRL is conducting research into integral 3D television as a new form of broadcasting media beyond Super Hi-

Vision. Integral 3D television obtains light rays from a 3D object and reproduces its optical image by using a lens array of

many microlenses for both capture and display. It does not require special glasses because the reproduced optical image

has horizontal and vertical parallax and allows observers to watch the optical image according to their viewing position in any

posture within a viewing zone.

Integral 3D television, which reproduces perspectives of an object from all directions (top, bottom, left and right), requires

a much larger amount of information than 2D images. To address this need, we have been conducting R&D on a camera and

display with a high pixel count as well as a 3D imaging system using multiple cameras and displays. This report describes a

prototype 3D imaging system that we have developed. It also introduces our studies on the technology to generate 3D models

from multi-viewpoint images and the technology to convert 3D models to integral 3D images with the aim of producing diverse

3D video content.

Preparations are under way for the trial broadcasting of Super Hi-Vision by satellite in Japan in accordance with our

predetermined schedule. Moreover, studies to realize next-generation terrestrial broadcasting are planned. NHK STRL has been

conducting R&D on large-capacity transmission technologies to realize terrestrial Super Hi-Vision broadcasting and has successfully

carried out Super Hi-Vision video transmission experiments using higher-order modulation and dual-polarized MIMO technologies.

This report introduces an overview of research on next-generation terrestrial broadcasting, which incorporates new

technologies into ISDB-T (Integrated Services Digital Broadcasting-Terrestrial), which is the current terrestrial broadcasting

system. It explains the technologies that we are currently developing such as an advanced signal structure that can select the

transmission capacity according to the mode of use, a new forward error correction technology and a single-frequency network

technology to enable stable transmission even with higher-order modulation. It also introduces a new technology to receive Super

Hi-Vision with the same antenna as that used for current terrestrial broadcasting while reducing the transmission capacity by the

combination of next-generation video coding and transmission technologies. Finally, it discusses our research on achieving a

smooth migration from current terrestrial broadcasting to next-generation terrestrial broadcasting.

With the development of the Internet and the widespread use of smartphones, the media environment surrounding us and our

lifestyles are changing drastically. In order for television to continue to live up to people's expectations as a familiar and reliable

medium amid the diversifi cation of information media, we believe it is necessary to redesign what TV ought to be in the Internet

and mobile era. NHK STRL aims to expand the range of TV-linked experiences to include viewing not just in front of the TV but

also outdoors and in various other scenes of our daily lives by combining the use of mobile devices with "Hybridcast," which is

a service platform for the convergence of broadcasting and telecommunications.

This report describes the concept of a "new TV experience," which brings new discoveries and values to everyday life by

proving TV programs and related information to mobile users depending on their circumstances. We also present two key

technologies to realize the concept. One technology is "media-unifying technology," which automatically selects the appropriate

video viewing method according to the user’s reception environment and the available broadcast/Internet channels for the

intended program. The other technology is "contents-matching technology for daily life," which offers users the topics and

information provided in TV programs in connection with their daily life.
