bit_depth_luma_minus8 = 0
bit_depth_chroma_minus8 = 0
BitDepthY = 8 + bit_depth_luma_minus8
BitDepthC = 8 + bit_depth_chroma_minus8
Maybe things will become a bit more clear in a later draft. IBDI may be restricted to the profile extensions to be defined in 2014. Google seems to have a few older references to a "High Efficiency Profiles" supporting IBDI in addition to "Main Profile" which didn't, but maybe that got scrapped for the time being to meet the January 2013 deadline they set. It will be interesting to see how this all develops over the next few years.

Yeah, okay, I see now... There definitely seemed to be nothing in the draft about adaptive bitdepth...
Too bad.
By the way, wouldn't quantum computers enable incredibly fast and effecient video compression?
Quantum computers are essentially parallel matrix multipliers, and there's already algorithms (similar to Shor's factoring algorithm) which can do fourier tranforms on quantum states in n log n time.
Has anyone actually done any research into applying quantum computers to mpeg-like video compression? Or better yet design a new video compression scheme that takes advantage of the types of calculations quantum computers are good at?
