The Advanced Television Systems Committee (ATSC) is pleased to announce the approval of A/153 ATSC Mobile DTV Standard. The ballot, tallied at midnight Oct. 15, was approved with overwhelming support by the full ATSC membership.
The ATSC Mobile DTV Standard defines the technical specifications necessary for broadcasters to provide new services to mobile and handheld devices using their digital television (DTV) 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 Mobile DTV was developed to support a variety of services including free (advertiser-supported) television and interactive services delivered in real-time, subscription-based TV, and file-based content download for playback at a later time. The standard can also be used for transmission of new data broadcasting services.
"Development and adoption of the ATSC Mobile DTV Standard is a major milestone in the ongoing evolution of digital television," said ATSC President Mark Richer. "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."
The ATSC Mobile DTV Standard will enable broadcasters to provide new compelling services to consumers utilizing a wide array of wireless receiving devices including mobile phones, small handheld DTVs, laptop computers and in-vehicle entertainment systems.
Gary Shapiro, President and CEO of the Consumer Electronics Association, 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 deployment. With the successful digital television transition now behind us, the ATSC Mobile DTV standard gives broadcasters an opportunity to provide consumers with the next generation of compelling over-the-air content."
"This milestone ushers in the new era of digital television broadcasting, giving local TV stations and networks new opportunities to reach viewers on the go," said Paul Karpowicz, NAB Television Board Chairman and President of Meredith Broadcast Group. "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."
ATSC Chairman Glenn Reitmeier added: "On behalf of the ATSC Board of Directors, I would like to congratulate all of the ATSC member companies that contributed to this major achievement. The ATSC Mobile DTV standard is flexible and robust, enabling a range of services business models that create new opportunities for broadcasters, device makers and consumers. It is particularly noteworthy that ATSC Mobile utilizes Internet Protocol (IP), 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."
ATSC Mobile DTV is built around a highly robust transmission system based on Vestigial Side Band (VSB) modulation, with enhanced error correction and other techniques to improve robustness and reduce power consumption in portable receivers, coupled with a flexible and extensible Internet Protocol (IP) based transport system, efficient MPEG AVC (ISO/IEC 14496-10 or ITU H.264) video, and HE AAC v2 audio (ISO/IEC 14496-3) coding. ATSC Mobile DTV services are carried in existing digital broadcast channels along with current DTV services without any adverse impact on legacy receiving equipment.
In addition to live television, the new ATSC Mobile DTV standard provides a flexible application framework to enable new receiver capabilities. Receivers that make use of an optional Internet connection will enable new interactive television services, ranging from audience measurement and simple viewer voting to the integration of Internet-based applications and transactions with television content.
Formal development of the ATSC Mobile DTV system began in May 2007 with the issuance of a request for Proposals (RFP). The new standard document will be available online at the ATSC website [1].
The Advanced Television Systems Committee is an international, non-profit organization developing voluntary standards for digital television. The ATSC member organizations represent the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite, and semiconductor industries. ATSC creates and fosters implementation of voluntary Standards and Recommended Practices to advance terrestrial digital television broadcasting, and to facilitate interoperability with other media.
