"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.

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, highspeed 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:

12
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.

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
stream
2. 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 protocol
4. A service multiplexer to multiplex the conventional ATSC stream with
Mobile DTV data
5. 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.

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
