'Candidate' Mobile DTV Standard Approved

The Advanced Television Systems Committee has upped its anxiously
awaited mobile/handheld standard (ATSC M/H) to Candidate Standard
status, another benchmark in the journey to deployment of actual mobile
DTV standard.

It includes a highly robust transmission system based on vestigial
sideband (VSB) modulation coupled with a flexible and extensible
IP-based transport, efficient MPEG AVC (H.264) video and HE AAC v2 audio
(ISO/IEC 14496-3) coding, ATSC said Wednesday.

The Candidate Standard provides a flexible application framework for
running software on receivers, ATSC said. This will enable new
interactive services on Web-connected receiving devices, potentially
letting viewers buy, vote or communicate back to TV stations using
mobile devices.

The Candidate Standard stage of ATSC standards development is an
explicit call for implementation and technical feedback, the committee

"ATSC Mobile DTV will allow broadcasters to leverage the wireless and
local nature of their DTV transmission" said ATSC President Mark Richer
in a statement. "Broadcasters will be able to provide new compelling
services to consumers utilizing a wide array of wireless receiving
devices including mobile phones, small handheld TVs, laptop computers
and in-vehicle entertainment systems. Many of these devices will utilize
existing ubiquitous technologies to provide a return channel for true
interactive applications."

The architecture of the Candidate Standard will make terrestrial
broadcasting an important segment of the Internet, said Glenn Reitmeier,
chairman of the ATSC Board of Directors.

The ATSC Specialist Group on Mobile & Handheld, chaired by Mark Aitken,
director of advanced technology for the Sinclair Broadcast Group,
evaluated the proposals and drafted the standard.

The Candidate Standard consists of eight parts:

* Part 1 - Mobile/Handheld Digital Television System
* Part 2 - RF/Transmission System Characteristics
* Part 3 - Service Multiplex and Transport Subsystem Characteristics
* Part 4 - Announcement
* Part 5 - Presentation Framework
* Part 6 - Service Protection
* Part 7 - Video System Characteristics
* Part 8 - Audio System Characteristics
