H.264 profiles

유선방송 중심(uhd tv, 3d tv, iptv)으로 h.264로 전환되기 시작했다. 지상파 방송의 경우 mpeg2에서 h.264로 넘어가기 이른감이 있어 지지부진 하다가 uhd 방송을 시작히는 기점(2016년 전후)에 h.264를 건너뛰고 atsc 3.0 즉 h.265를 채택했다. This paper presents the architecture, design, validation, and hardware prototyping of the main architectural blocks of main profile H.264/AVC decoder, namely the blocks: inverse transforms and quantization, intra prediction, motion compensation and deblocking filter, for a main profile H.264/AVC decoder.

The profiles are basically a set of constraints for various encoding settings. They tell the encoder what settings are allowed to be used or not. It's a bunch of standards set to ensure compatibility within certain classes of devices, usually.Improper claims. Please be aware that there are companies improperly claiming ONVIF conformance for their products. To avoid being misled, users are encouraged to verify conformance using the ONVIF Conformant Products search page, which is the only authoritative source for confirming if a product is officially ONVIF conformant. Pre-reading: H.265, aka HEVC, is the successor to H.264. H.265 is meant to double the compression rates of H.264, allowing for the propagation of 4K and 8K content over existing delivery systems. Videos encoded with HEVC will maintain the same high-quality as the equivalent H.264 video, but at a smaller file size.

Which ones it's allowed to enable is defined by the profile. Profiles ensure compatibility between devices that have different decoding capabilities.

  7. In addition to the profiles, the H.264/AVC specifications also define a number of levels. While profiles define which compression features of H.264 may (or may not) be used, the levels put further restrictions on other properties of the video. These restrictions include the maximum resolution, the maximum bitrate, the maximum framerate (for a given resolution) and the maximum number of reference frames (indirectly limited though MaxDPB).
