Video encoding method and video decoding method for enabling bit depth scalability

摘要: The invention presents a scalable solution to encode the whole 12-bit raw video once generate one bitstream that contains an H.264 /AVC compatible base layer and enhancement layer. If color bit depth decoder is available at client end, both sub-bitstreams will be decoded obtain it can viewed on high quality display supports more than eight bit; otherwise only sub-bitstream using 8-bit conventional display. residual based prediction from layer, which either bit-shift or advanced utilized, wherein method Smoothed Histogram Localized Polynomial Approximation method.
