ATSC announces approval of mobile DTV standard
The Advanced Television Systems Committee (ATSC) recently announced the approval of the A/153 ATSC Mobile DTV Standard.
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.
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. ATSC chairman Glenn Reitmeier stated that ATSC Mobile utilizes Internet Protocol (IP), which will enable broadcast services to be easily integrated with wireless broadband consumer devices and applications.
ATSC Mobile DTV is built around a 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 an Internet Protocol (IP) based transport system, 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 on the ATSC Standards page.
