Mobile DTV Standard Adopted
WASHINGTON: After two years and five months in
development, the mobile DTV standard had been approved. The Advanced Television
Systems Committee said today it has approved the ATSC Mobile DTV Standard,
A/153. The ballot, tallied at midnight Oct. 15, was approved with overwhelming
support by the full ATSC membership.
“Development and adoption of the ATSC Mobile DTV Standard is a major milestone
in the ongoing evolution of digital television,” ATSC President Mark Richer
said “We have been fortunate to have strong and active industry support,
including thousands of person-hours of technical volunteers, for this work
which enabled us to develop the standard in an efficient manner.”
A/153, also known as ATSC M/H, defines the technical specifications necessary
for broadcasters to provide new services to mobile and handheld devices using
their digital television transmissions. The new services for mobile and
handheld devices are carried along with current DTV services without any
adverse impact on legacy receiving equipment.
ATSC M/H supports a variety of services, including advertiser-supported
television, real-time interactive media, subscription-based TV, and file-based
content download. The standard can also be used for transmission of new data
broadcasting services. It will give broadcasting access to the mobile video
arena of cell phones, small handheld DTVs, laptop computers and in-vehicle
Stations across the country began field testing ATSC M/H earlier this year.
Some 33 are expected to be transmitting the mobile format by the end of this
month, though many lack the prototype handhelds necessary to test reception.
LG, Samsung, Kenwood and Dell are the lead manufacturers for A/153-compatible devices.
Receivers ready for prime time are expected to be on display at the Consumer
Electronics Show in Las Vegas in January.
Gary Shapiro, president and CEO of the CEA, said, “As a founding ATSC member,
CEA congratulates ATSC on achieving this new standard, which will help
chipmakers and equipment manufacturers proceed with product development and
ATSC M/H is based on vestigial sideband modulation, with enhanced error
correction and other techniques to improve robustness and reduce power consumption
in portable receivers, coupled with a flexible and extensible IP-based
transport system, MPEG AVC video, and HE AAC v2 audio coding. It will carry
existing digital broadcast channels in addition to new services such as
interactive TV, available on broadband-enabled ATSC M/H receivers.
Paul Karpowicz, NAB Television Board chairman and president of Meredith
Broadcast Group had this to say: “This will introduce the power of local
broadcasting to a new generation of viewers and provide all-important emergency
alert, local news and other programming to consumers across the nation.”
Glenn Reitmeier, ATSC chairman:: “It is particularly noteworthy that ATSC
Mobile utilizes Internet Protocol, which will enable broadcast services to be
easily integrated with wireless broadband consumer devices and applications,
further reinforcing the significant role of terrestrial television broadcasting
in the media landscape for decades to come.”
From Dennis Wharton of the NAB: “We strongly believe that all Americans will
benefit from the advanced capabilities of mobile DTV and broadcasters’
innovative use of over-the-air spectrum.”
The new standard document will be available online on the ATSC Standards page.
