Digital TV Standard approved for the US

htcimagio2 The Advanced Television Systems Committee (ATSC) have announce the approval of A/153 ATSC Mobile DTV Standard.

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 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, allowing full quality reception at speeds up to 100 mph, 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.
