The Advanced Television Systems Committee (ATSC) announced the approval of A/153 Mobile DTV Standard, which defines the technical specifications necessary for broadcasters to provide new services to mobile and handheld devices using digital television (DTV) transmissions.
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.
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.
The draft version of A/153 specifications is available here. Note that Part 7 "Video System Characteristics" (pdf) includes the ITU-T/MPEG Scalable Video Coding technology.
