This ITU-T Technical Paper addresses the use of audio and video coding in services delivered over Internet Protocols (IP). This document describes specific codecs for use within an IPTV environment. For audio coding, it describes the use of MPEG-1 Layer II, AC-3, E-AC3, HE AAC v2 audio, Extended AMR WB (AMR WB+) audio, MPEG 2 AAC, MPEG-4 HE AAC, MPEG-4 HE AAC v2, MPEG Surround, MPEG-4 ALS, G719, G.722, G.722.1, G.722.1 Annex C, G.722.2, G.729.1, G.711.1 and G.718. For video coding, it recommends support for ITU-T H.265 | ISO/IEC 23008-2 HEVC and H.264 | 14496-10 AVC, and also lists some additional video coding technologies that have been identified in member contributions as potentially relevant to the application (ITU-T H.262 | ISO/IEC 13818-2 MPEG-2 Video, AVS, H.263, MPEG-1, MPEG-4 Part 2, and VC-1). This document adopts a "toolbox" approach for the general case of IPTV applications delivered directly over IP and MPEG2 -TS. This document is not a specification for the use of audio or video codecs in IPTV Services.
