High 10 Profile is not some custom codec developed by a "group". It is part of the H.264 recommendation from ITU-T. It is just that while the anime world embraced it, the rest of the world shunned it.

First of all, Hi10 does see usage outside of the 'Anime World', though it's almost exclusively in the realm of prosumer and professional level video recorders for various kinds of film production. Film production routinely see's hardware capable of capturing images beyond 8 bits per channel that we typically see in consumer products. This is where a compressed 10bit storage format gets usage. This is of course specialized hardware and no where else do you see 10bit. It was never seen in any disc media or any streaming media, which is the exact media that low cost hardware decoding chips are designed for. They are built to decode consumer video on consumer products. Adding features beyond what is needed, for a super niche area of content, makes no financial sense and this is why you see no hardware companies bothering to embrace it. 10bit is not 'shunned by the rest of the world', it just doesn't make any financial sense to build hardware for a narrow region of a format that only see's usage in some pro hardware and on pirated anime.

If you are going to equate all 10-bit to High 10 profile, then I really don't know what to tell you. I have never heard of Hi10P used for broadcast or professional video. To the best of my knowledge, Hi422P, Hi444P, Hi10Intra50/100 are the ones used in broadcast/professional video applications. I know you work in post production, so I'm all ears...

Yep - 4:2:0 10bit H264 Long GOP ? If you are using 10bit why not use 4:2:2? I see quite a lot of H264 4:2:2 LongGOP use (it's a standard codec for satellite and fibre contributions for broadcast TV) but 8bit is still the norm.

Hardware acceleration of 4:2:2 H264 is also not standard on consumer gear...
