3D-TV STANDARD APPROVED
ATSC has finalized the first of three proposed approaches to terrestrial broadcasting of 3D-TV, and the first of the multi-part standard has been published. The new ATSC A/104 Standard for 3D-TV Terrestrial Broadcasting using “Service Compatible Hybrid Coding” (SCHC) consists of broadcast Stereoscopic 3D video, along with audio and ancillary data. The Stereoscopic 3D video has left view and right view, where one of the two views can be used as 2D image for the legacy 2D-TV.
The Stereoscopic 3D video is transmitted as two independent video elementary streams, where one of them is compatible with the legacy 2D TV service. Ancillary data includes program/channel signaling data and caption information. Signaling data is transmitted via multiplexing, while caption information is transmitted along with the video bit stream.
The 3D-TV service is transmitted along with normal DTV programming in a compatible manner that does not interfere with legacy systems. No additional spectrum is required for this service. The ATSC 3D-TV suite of standards is organized in a series of parts based on deployment architecture. Additional parts are expected to be added later this year.
