"Local news and sports, together with highly promoted and branded network

content, will be fundamental to the mass appeal and adoption of Mobile TV; just as

they have historically, and without exception, been for every major advance in television over the past half century – cable, VOD, DVR, and now Mobile TV."

The Power of Local TV on the Go

Mobile Digital Television (DTV) represents a significant new revenue stream for the

broadcasting industry as well as a new way to reach more customers. Affordable

transmission facility improvements allow broadcasters to extend local programming to

a vast audience of viewers with portable Mobile DTV devices. As mandated digital

conversion has (finally!) completed in the U.S., Mobile DTV has emerged as an important way

for broadcasters to extend their franchises.

Consumers Seek Mobility

Mobile DTV makes local, digital broadcast TV portable. With Mobile DTV, consumers can tune in to live, local news, traffic

information, weather, sporting events or entertainment programs from the convenience of their car, at the beach—wherever they may be, using a variety of mobile and video

devices.

For consumer electronics manufacturers and automakers, extending broadcast-quality TV to portable devices opens up a vast new market. Improved picture quality and access to

more programming choices and local content will drive consumer interest, which makes Mobile DTV a great

opportunity for consumer electronics manufacturers and automakers to develop the cool devices that will capture a

major share of this market. Indeed, studies have predicted a range from 25 million to 100+ million mobile broadcast end-

users worldwide by 2010.Source: www.openmobilevideo.com

Consumers Seek Mobility

Additionally, Mobile DTV makes public safety information accessible from virtually anywhere. Consumers will be able

to receive their normal TV fare on a mobile device, delivered in full-motion video and complete with local news, traffic and

weather updates.

The broadcasting industry has embraced Mobile DTV as an enhancement of the conversion of its TV signals from old-

fashioned analog transmission to modern digital transmission. This conversion clears a considerable portion of

the airwaves, now devoted to the analog signal, for new services. Full-motion, mobile digital television is the most prominent of these services currently being developed.

Broadcasters reap the benefits of Mobile DTV’s crisp picture, high-speed mobility and a wealth of new multicast choices –

all made possible through the digital broadcast signal.

The current network of broadcast transmission towers that carry TV signals to your home will be retrofitted to also deliver a Mobile DTV signal. That signal has the ability to deliver local, full-motion digital broadcasts on multiple mobile devices, without the need for additional broadcast spectrum.

The Mobile DTV platform enables local TV stations to deliver live, digital content to ATSC-capable mobile and video devices such as mobile phones, portable media players, laptop computers, personal navigation devices and automobile-based “infotainment systems.” The service is “in-band”, meaning local broadcasters are providing mobile TV services as part of their terrestrial transmission within the same, existing 6 MHz channel they use for their current ATSC DTV programming.

With little cost, broadcasters can install a Mobile DTV exciter and signal encoding equipment on existing TV transmission systems and gain the ability to transmit a robust, digital mobile TV signal. Consumers will receive that signal on various Mobile DTV devices. The Mobile DTV system allows the splitting of the 19.4 Mb/s of capacity into a slice for delivery to current DTV receivers and a slice for Mobile DTV technology that can be received on new Mobile DTV-capable receivers.

Bandwidth Flexibility for Mobile Transmission

Digital TV allows for bandwidth flexibility, providing a number of possibilities for broadcasters to divide bandwidth and distribute channel usage.

These illustrations show examples of channel usage for mobile operation…

Mobile DTV Performance Capabilities

Mobile DTV will enable broadcasters to deliver consistent performance and functionality across a range of service requirements:



Video quality - Delivering one or more compelling, high-quality mobile/handheld video programs that provide excellent viewing experiences using H.264 base profile video encoding now, and even better resolution (up to 480p) in the future.

Mobile reception - Clear, consistent reception tested at speeds greater than 100 miles per hour. The system processes the mobile program stream(s) with additional forward error correction and data redundancy to help ensure successful reception.

Efficient/flexible use of spectrum - Mobile DTV provides for robust delivery of programming. Bandwidth flexibility is evident in the number of audio/video services, data rates and the signal robustness attainable with main ATSC data requirements.

Backward compatibility - 100 percent backward compatibility with all existing/deployed ATSC consumer equipment/receivers. Compatibility eliminates the risk of DTV service disruption and reduces additional equipment cost for broadcasters.

Device/UI parameters - With only a single receiving antenna required, design options are maximized and ease of use is enhanced. Convenience features (e.g. programming guide, time-shifting and storage) are part of the system architecture. Significant mobile/handheld receiver power savings result from bursted transmission that maximizes receiver battery life.

Mobile DTV Receiving Devices

Video enabled devices capable of receiving broadcast TV services continue to be developed and upgraded by manufacturers. These devices include mobile phones, portable media players, laptop computers, personal navigation devices and automobile-based “infotainment” equipment.


15

Integrating Mobile DTV

The process of integrating Mobile DTV transmission with an existing ATSC plant is not difficult; these are the basic

devices required for local origination and network services:

1. A video (AVC) and audio (HE AAC v2) encoder for each added program stream2. An IP path into the facility (for remote component ingest)3. An IP encapsulator to encapsulate all program streams and non-real-time files into the appropriate transport protocol4. A service multiplexer to multiplex the conventional ATSC stream with Mobile DTV data5. A Mobile DTV enabled exciter to replace the existing exciter in the ATSC transmitter

The Mobile DTV architecture provides full compatibility with all industry-standard ATSC equipment. Additionally, the

system is compatible with all current microwave and fiber STL systems.


16

Mobile Benefits

When a Mobile DTV system is implemented, broadcasters can expect the following operational and financial benefits:

Leveraged investment in ATSC transmission

Delivery of robust DTV signals to Mobile DTV receiving devices

Extension of local branding to mobile users

The ability to redirect local news, weather, sports and traffic information to “consumers on the go”

The addition of up to eight program (streams) of mobile content per station

New revenue opportunities based on subscription, advertising and sell-through transactions
