ITU-R BT.1870-1 1 RECOMMENDATION ITU-R BT.1870-1 Video coding for digital television broadcasting emission (Question ITU-R 12/6) (1995-1997-2010-2015) Scope This Recommendation specifies video coding standards to be used for digital
9、 broadcasting emission. Keywords Video bit rate reduction, video source coding The ITU Radiocommunication Assembly, considering a) that the transition from analogue to digital broadcasting is ongoing around the world; b) that it is desirable to have maximum commonality between digital systems for di
10、fferent emission and secondary distribution media (e.g. to the home receivers); c) that Recommendation ITU-R BT.1203 provides user requirements for video bit-rate reduction coding of digital TV signals for an end-to-end television system; d) that Recommendation ITU-R BT.1737 specifies the use of the
11、 video source-coding method as per Recommendation ITU-T H.264 | ISO/IEC 14496-10 for the transport of HDTV programme material for a variety of broadcasting applications; e) that Recommendation ITU-R BT.2073 specifies the use of a video source-coding method as per Recommendation ITU-T H.265 | ISO/IEC
12、 23008-2 for the transport of UHDTV and HDTV programme material in broadcasting, recommends 1 that digital television broadcasting emission systems should make use of one of the video-coding standards described in Recommendation ITU-T H.262 | ISO/IEC 13818-2 (MPEG-2 Video), Recommendation ITU-T H.26
13、4 | ISO/IEC 14496-10 (MPEG-4 AVC), and Recommendation ITU-T H.265 | ISO/IEC 23008-2 (MPEG-H HEVC); 2 that the video-coding standard of Recommendation ITU-T H.265 should be preferred for new implementations of digital television broadcasting emission systems; 3 that Recommendation ITU-R BT.1203 shoul
14、d be duly considered in selecting the tools and parameters of the video coding standards, and further recommends that when new video coding standards are produced by the international standardization bodies, they should be considered for possible introduction into digital television broadcasting emission systems by conducting tests and analyses of performance and functionality.
