The video compression algorithm specified in Recommendation ITU-T H.265 | ISO/IEC 23008-2 High Efficiency Video Coding (HEVC) is recommended as being particularly well suited for use in IPTV services. The format range extensions (RExt) and screen content coding (SCC) extensions to HEVC may also be suitable.
The video compression algorithm specified in Recommendation ITU-T H.264 | ISO/IEC 14496-10 Advanced Video Coding (AVC) is also advised for use in IPTV services. The inclusion of support for Recommendation ITU-T H.262 | ISO/IEC 13818-2 "MPEG-2 video" support in IPTV services may also be suitable, in consideration of the prevalence of existing encoded bitstreams in that format.
However, determining which coding technology designs should be supported in a particular deployment may be based on a wide variety of factors. Some additional video coding technologies that have also been identified in member contributions as potentially relevant to the application include the following:
GB/T20090.2 "AVS"
ISO/IEC 11172-2 "MPEG-1 video"
ISO/IEC 14496-2 "MPEG-4 visual"
Recommendation ITU-T H.263
SMPTE 421M "VC-1"
FSTP-FNTP (2006-11)
