Th is past year has been very r ich in events in the Broadcast sector, particularly for Satell i te C o m m u n i c a t i o n s a n d D i g i t a l Terrestrial Broadcasting. The notion of ‘convergence’ that was all the buzz in the 2000’s, now seems to be following once again the “Hype” development c y c l e . To d a y, c o n v e rg e n c e i s perceived by industry players as an inescapable strategic direction that will make it possible to forge new opportunities necessary for the future competitiveness of terrestrial and satellite platforms, in the face of Broadband and Mobile infrastructures in full expansion.

Convergence of networksWhether for Satellite or Terrestrial e c o s y s t e m s , t h e c o n v e rg e n c e o f n e t w o r ks w i t h B ro a d b a n d infrastructure is certainly underway. The ATSC conference , he ld on M a y 1 7 , 2 0 1 7 i n Wa s h i n g t o n , marked the finalization of a 4-year standardization process which has resulted in the definit ion of the new ATSC 3.0 standard. This is a significant achievement, because it is a standard that provides the technical means necessary for the deployment of new services by Broadcasters, by combining the best Broadcast and Broadband network features. It is a technological breakthrough that directs the architectures towards an

"all IP" scenario.As for convergence in Satel l i te systems, DTH incumbents are seeking greater diversity and are investing in technical solutions optimized for IP transmission, and setting up interactive links, as illustrated by the

“SmartLNB” services at Eutelsat and “SAT> IP” at ASTRA.

Convergence of usagesThe concept of convergence also appl ies to usage. Broadcasters and operators wish to broaden the applications of their platforms, not only to continue to deliver content to fixed TV, especially by supporting UHD services, but also to address other types of terminals, such as tablets and mobile receivers. The strategy put in place by the SINCLAIR group in the US is highly representative of this new impetus, w i th the target to a d d r e s s " M o b i l e First" services. This evolution is of course facilitated by some key technical factors such as: OFDM for ATSC 3.0 to address mobile uses; Scalable HEVC (a scalable extension of HEVC), which enables the coding to adapt to the terminal; and techniques of multi-beam broadcasting in the satellite segment.

Convergence of contentIn a day-to-day environment, where social networks are ubiquitous, the individual becomes a target on which content must converge in a precise and personalized manner. Faced with competition from the mobile

‘phone networks, which are inherently unicast, Terrestrial Broadcast and

S a t e l l i t e n e t w o r ks must adapt to enable t h e d e l i v e r y a n d downloading of more and more targeted and personalized content.

At TeamCast, we are at the forefront o f

the trend towards convergence, with ongoing projects for both satellite and terrestrial broadcasting. The new platforms we have developed this year, such as VORTEX II and TYGER, illustrate the evolution towards "all IP" architectures. The launch of the

"Convergence TV" research project with a consortium of seven Broadcast and Broadband ecosystem partners, led by TeamCast, is a strong confirmation of our commitment and investment. Finally, the concept of convergence is also perfectly illustrated by the merger of the Enensys and TeamCast teams, strengthening our ability to accommodate our customers with a complementary, innovative and efficient range of products.

TECHNOLOGYBy Gerard FARIA, VP Technology

DVB-T2...ATSC 3.0...AND THEWINNER IS...COFDM!Since the standardisation of the ATSC 3.0 Physical Layer, Coded Or thogonal Frequency D iv is ion Multiplex modulation (COFDM) has become THE modulation scheme for all terrestrial wireless systems, including both Digital Broadcast Transmission (DAB, DVB, ISDB, DTMB, etc.) and Digital Broadband Communication systems (WiFi, WiMax, 4G-LTE, etc. ) . Undoubtedly, this success results from the resilience of the OFDM waveform to multipath propagation impairments (i.e. signal echoes), and the robustness of the Forward Error Correction (FEC) codes used to recover the data losses during terrestrial transmission.In the case of stationary terminals r e c e i v i n g s i g n a l s f r o m a n omnidirectional transmitting antenna, the signal at the receive antenna includes both the direct line-of-sight modulated wave, plus many replicas (echoes) arriving via various multipath reflections. Each multipath echo is delayed by one microsecond for every 300 metres it travels further than the direct line-of-sight received wave. However, by spreading the modulation across thousands of subcarriers in parallel, the modulation symbol period on each of the subcarriers becomes significantly greater than the delay time of the echoes. Thus, it is only a small portion of the modulated symbol that is polluted by the late arrival of the echoes of the previous symbol.To maximize the number of subcarriers in the channel, the inter-carrier spacing is defined as the inverse

of the symbol duration. This is the critical condition that characterises an Orthogonal Frequency Division Multiplex (OFDM). The duration of each modulated symbol can also be extended at its beginning to constitute a guard interval (GI), giving extra protection from echoes, without generating any phase discontinuity. Nowadays, of course, users of the terrestrial transmission platforms wish to access content in various conditions of mobility. In this case, the service no longer involves just a rooftop antenna nicely pointing to the transmission site that it is serving, but now encompasses receiving terminals in motion, both outdoors and indoors, and with antennas likely to be buried within the receiver itself. The receiving terminals must cope with echoes not only delayed in time, but also shifted in frequency - this ‘Doppler’ frequency shift being proportional to the speed of the terminal’s motion and to the angle of arrival of the echo at the antenna.Since th is extension of symbol duration works against the objective to transport information efficiently, the infrastructure serving stationary receivers aims in practice to maximize the number of subcarriers, and in this way to minimize the GI overhead. The effect of this is that the inter-carrier spacing becomes extremely reduced; and when the replicas of the wave are received shifted in time (i.e. echoes resulting from multipath propagation), and shifted in frequency (i.e. Doppler shift resulting from reception in

motion), the orthogonality of the subcarrier multiplex is destroyed, and the information data are lost. There is thus a dilemma posed by the parameterisation of the waveform to serve optimally and simultaneously, both stationary and mobile terminals. Hence the architects of the physical layer for the new ATSC 3.0 standard have defined that every ATSC 3.0 frame should start with a lock (i.e. bootstrap), followed by a table of contents (i.e. preamble), to introduce a set of subframes during which the waveform attributes (i.e. FFT and GI size, Pilot Pattern etc.) can be tuned differently, in order to facilitate either stationary or mobile reception modes.Beyond the improvements in the waveform structure supporting the modulated subcarriers, the second-genera t ion broadcast systems, DVB-T2 and ATSC 3.0, also use the concept of multiple physical layer pipes (PLPs). Each PLP input channel offers a specific transport / robustness compromise, by managing the amount of FEC code (i.e. code rate) inserted in the data flow being transported. This technique helps overcome the problem that, at any given location, receivers may not enjoy the same RF coverage and level of carrier signal power C, while all receivers will experience the same level of noise power N. Under these conditions, only some of the receiver population will be able to exploit all transmitted PLPs, while others will receive only a part of the transmitted PLPs.

5

As we have outlined in this article, in any COFDM based transmission system with the proper construction of the transmitted waveform, the Guard Interval enables the cancellation of unwanted echoes at the receiver. This applies both to the natural echoes resulting from multipath propagation, and the artificial ones produced by co-channel transmitters simulcasting identical broadcast services, as used for SFN. Accordingly, to increase the field coverage over a large inter-site area, any SFN transmitter must be identifiable at any instant as an

exact echo of all others transmitters; and at any point in the area served by the SFN, the delay spread of the unwanted echoes - either natural or artificial - must be smaller than the Guard Interval duration.To meet our customers’ requirements and to respond to the question

“What coverage can we expect from our transmission facility with such waveform (subframe) and encoding (PLP) settings?”, an evaluation of the link budget for C/N must be made. An ATSC 3.0 calculator is available on request at info@teamcast.com and this convenient tool is able to

estimate the coverage obtained by a single transmitter or even two transmitters in SFN mode.As illustrated below, taken individually, the field produced by a single transmitter may be insufficient to provide full inter-site coverage; but the sum of the fields at a receiver produced by two “exact echoes of each other” SFN transmitters, can achieve the delivery of four PLPs transported on two subframes, to four populations of receiving terminals within a single broadcast infrastructure.

Readers will have noticed that ATSC 3.0a n d D V B -T 2 h a v e n u m e r o u s similarities: both use the COFDM modulat ion scheme; both of fer flexibility in customising the OFDM waveform for stationary and mobile reception; both implement multiple PLPs based on LDPC error correction; both offer several ways to distribute the PLPs over the OFDM waveform; and, most importantly, both enable the broadcast transmission to operate close to the optimal ‘Shannon limit’.Consequently, it is not at the level of

the physical layer that differences between the systems must be sought, but in the transport layer, and in the method of documenting the broadcast services: DVB re-uses middleware originally defined for its 1st generation of Digital TV systems; while ATSC has made the more d isrupt ive choice of specifying a 2nd generation middleware based on the Internet Protocol … BUT, all the 2nd generation infrastructures developed by DVB (i.e. DVB-T2, DVB-S2, and DVB-C2) have stipulated two types of access

- Transport Stream (MPEG2-TS) and Generic Stream Encapsulation (GSE); whereas, ATSC 3.0 has specified the ATSC Link Protocol (A/331 - ALP), which allows the network operator to broadcast packet streams having either IP or TS formats. Accordingly, both the ATSC & DVB infrastructures are ready to deliver services in the preferred format of today, or in the preferred format of tomorrow … and that dictates the conclusion of this paper: the winner is

… COFDM.

ATSC 3.0 FIELD TESTS IN CLEVELAND —Under an experimental broadcast licence from the FCC, the terrestrial station located in Cleveland, Ohio, and owned by Tribune Broadcasting’s WJW-TV, has been used by NAB and CTA to conduct a new session of field testing for the emerging ATSC 3.0 standard, during the Spring and Summer of 2017. This initiative comes at a perfect time, as many US broadcasters have been assigned new channels as a result of the repacking process associated with the US incentive auction; and the industry is thus very interested in collecting general performance figures for ATSC 3.0 transmissions.

For this trial, an existing Comark transmitter was selected and turned on. The transmitter includes an ATSC 3.0 high-end exciter designed by TeamCast, and radiates a 30kW ERP signal on channel 31.

SUPPORT OF GSE FORMAT IN Green4DAB MODULATOR BRINGS GREATER FLEXIBILITY

VORTEX II comes as a ready-to-use stand-alone rack modulator/exciter, specifically designed to be integrated inside new and exist ing DTV transmitters. I ts

“DualCast” modulation capability meets Broadcasters’ requirements for a smooth and straightforward transition from ATSC 1.0 to ATSC 3.0 using the same hardware platform. When used in its ATSC 1.0 mode, VORTEX II integrates unique and unrivalled pre-correction techniques to compensate for “Very-Sharp Tuned” filter nonlinearities. Obviously with the current FCC spectrum repack process, it is expected that digital adjacent channel filtering will become more critical to meet the need to accommodate all US broadcasters. Thus, more complex and “Very-Sharp Tuned” filters will be required, and the effects of these will have to be properly pre-corrected by the modulator.

VORTEX II integrates the state-of-the-art ATSC 3.0 modulation core.The implementation of complex input IP packet buffer and multi-layers PLP (Physical Layer Pipes) frame builder and the possibility for future waveform support (thanks to the bootstrap signalling) has conducted TeamCast’s engineers to completely review the modulator hardware implementation for a more powerful and IP centric design architecture.

Like all other exciters from TeamCast, VORTEX II brings several key features to ease the in tegrat ion wi th in transmitter design, and to achieve the highest level RF performance and energy savings. Features include: state-of-the-art Digital Adaptive Pre-correction; an Automatic Gain Control (AGC) process to ensure correct output power stability; and monitoring of key transmitting power measurements, such as Forward Transmitted Power and Reflected Power levels.

Generic Stream Encapsulation (GSE) is a standardised protocol enabling IP packets to be carried on a satellite link, in a flexible and efficient way. Encapsulation of DAB Interfaces (EDI)

is a standardised IP format for distributing a DAB signal from the network head-end to the transmitters.W h i l e Te a m C a s t ’s p o w e r f u l G re e n 4 DA B m o d u l a to r a l re a d y supports widely-used input standards such as ETI (Ensemble Transport Interface, over G703 or satellite) and EDI (over Ethernet), it now supports EDI also over satel l i te with i ts embedded satellite demodulator and

GSE de-encapsulation.This optional feature is compatible with any DVB-S/S2 modulator offering the GSE encapsulation protocol, such as TeamCast’s renowned VYPER family. It not only increases the range of input formats supported by the Green4DAB modulator, but also brings greater flexibility to network operators’ infrastructure.

ATSC 3.0 FIELD TRIALS PHASE 2ON AIR IN BALTIMORE AREAThe initial ATSC 3.0 test network setup in 2016 in Baltimore consisted of two transmitters operating in an SFN configuration on channel 41, (one Gatesair TX in Washington D.C. and one Accrodyne IOT TX in Baltimore, MD). This network is fed by a TeamCast ST2L system from a Network Operating Center (NOC) located in Baltimore. The Phase Two extension is running since the beginning of July 2017 and adds a Comark Parallax transmitter – delivering 7 kW after filter operating on a different frequency (Channel 43). This additional channel enables evaluation of new ATSC 3.0 service capabilities such as channel bonding.The picture below shows the joint Sinclair, ONE Media and TeamCast technical team completing the setup of the Phase 2 extension.

With TeamCast now being part of the ENENSYS group, all companies like TV Stations, Broadcasters and TX manufacturers, who wish to design and set-up ATSC 3.0 network architectures, will have the perfect turnkey solution specifically to operate their SFN network. Indeed, the ENENSYS gateway/scheduler (“ATSCheduler”) and the TeamCast ATSC 3.0 exciter (VORTEX II) are fully interoperable, and come together as a straightforward and ready-to-deploy solution. The ATSCheduler is normally located at either the NOC (Network Operating Centre) or the Studio, and is responsible for preparing and time-stamping the content stream to be distributed to the transmitter sites, via the STL (Studio to Transmitter Link) interface. At each transmitter site, the Vortex II receives the STL data stream and generates the corresponding RF signal. Vortex II also integrates key features to drive the transmitter, such as Digital Adaptive Precorrection, power measurements and Automatic Gain Control.

VIETNAMESEBROADCASTER VTC ADOPTS TwisterEXCITERS TO MIGRATE FROM DVB-T TO DVB-T2 —

Vietnam started their Digital Terrestrial TV service with a first trial in 2000. After a simulcast period from 2011 to 2015, the analogue switch-off was scheduled from 2015 to 2020. While the first networks used the DVB-T system with MPEG-2 encoding, the networks are now progressively converting to DVB-T2 and MPEG-4.

Vietnam Television Corporation (VTC), one of the three nationwide broadcasters in Vietnam, initiated their conversion in 2016, with the upgrade of six high power sites in six major cities. To perform this upgrade on six existing 10 kW IOT based transmitters, VTC selected TeamCast’s DVB-T/T2 TWISTER exciters, because of their high adaptability to existing transmitter architectures and their superior level of performance.

“Besides their easy integration into our transmitters and their high RF performance, we selected TeamCast’s TWISTER because it is easily controlled remotely and brings a top-class adaptive pre-correction, which ensures the highest signal quality and highest energy efficiency with our existing IOT amplifiers”, says Do Hoang Kien, Manager of VTC’s Broadcasting and Transmission Centre.

TeamCast and Broadpeak have demonstrated their cost-effective solution for an all-IP, multicast delivery of live video services via satellite, to multiscreen devices at home as well as in public areas.This innovat ion uses the latest advanced features of DVB-S2X Annex M - a process to split up wideband signals of up to 2 Gbps, in order to reduce receiver IC complexity and price for the mass market opportunities. By also being based on multicast adaptive bit rate (ABR) video delivery, the solution really offers a cost-effective way for distributing several thousand live TV services to unicast devices both inside the home and outside.

At the head-end level, the solution involves a unicast-to-mult icast converter from Broadpeak (BkE200), and a wideband IP (GSE) DVB-S2X modulator from TeamCast (TYGER). While at the receiving end, there is an IP DVB-S2X demodulator from TeamCast, and a multicast-to-unicast converter from Broadpeak (nanoCDN multicast ABR), which feeds a wide range of devices via standard unicast WiFi connections. It is projected that, in the near future, the demodulation and nanoCDN funct ions w i l l be ava i lab le in consumer STBs.

HIGH THROUGHPUT SATELLITEMODULATOR WITH S2X ANNEX MBesides being a high throughput satellite modulator offering rates up to 480 Mbaud for the DVB-S2 and DVB-S2X standards, and thus prov id ing up to 2 Gbps useful rates, TYGER is offering the latest Generic Stream Encapsulation (GSE) adaptation algorithm for IP transport. Most importantly, TYGER is meeting fully the requirements of the DVB-S2X “Annex M”, making it capable

TOWARD HTSOPTIMIZATION: BEAM HOPPING! —High Throughput Satellite (HTS) Systems have demonstrated their ability to deliver very high bitrate to end users and to reduce the cost of access per user. HTS technology is mainly based on a smart frequency plan and frequency re-use techniques to manage many spot beams and thus increase the total satellite capacity.Behind these HTS principles, satellite TWTAs are multiplied, but can be frequentially shared between several spot beams, which means the total TWTA power is simultaneously distributed over several beams (we can say, less power per beam). Beam Hopping technique is a way to dynamically reallocate the full TWTA power on a set of Spot Beams based on time sharing, thus reducing both the number of necessary frequency channels and the number of TWTAs. At the cost of additional synchronization algorithms to be set up at both the modulator and demodulator sides.Once again, Tyger, the high-end TeamCast Satellite Modulator Platform, has been selected to put in place a test bench to demonstrate the capability of DVB-S2X chipsets to support beam hopping.

of mixing services (broadcast and broadband) over the same satellite carrier. Specifically, it supports Time-Slicing, a process to split a wideband signal - of up to 2 Gbps - into a large number of independent low rates services, in order to keep the receiver IC complexity and price low, which will be mandatory requirements for future mass market adoption.
