I see mention of 4.2.2 feeds on these forums a search on google does not seem to bring much to light, what are they and why would you want to recieve them?
these are mostly used to transfer live transmission to the studio before these are broadcasted: news, sport, show, live events: not for the public. (raw footage, unedited)
High 10 Profile (Hi10P): Going beyond today's mainstream consumer product capabilities, this profile builds on top of the High Profile, adding support for up to 10 bits per sample of decoded picture precision.
High 4:2:2 Profile (Hi422P): Primarily targeting professional applications that use interlaced video, this profile builds on top of the High 10 Profile, adding support for the 4:2:2 chroma subsampling format while using up to 10 bits per sample of decoded picture precision.
High 4:4:4 Predictive Profile (Hi444PP): This profile builds on top of the High 4:2:2 Profile, supporting up to 4:4:4 chroma sampling, up to 14 bits per sample, and additionally supporting efficient lossless region coding and the coding of each picture as three separate color planes.
High Stereo Profile: This profile targets two-view stereoscopic 3D video and combines tools from the High profile with inter-view prediction capabilities of Multiview Video Coding extension.
