Codeword Space Reduction For Intra Chroma Mode Signaling For Hevc
Abstract: Intra prediction is used in state-of-the-art video coding standards such as AVC. The intra prediction modes are coded into the bitstream. Luma and chroma components could potentially have different prediction modes. For chroma components there are 5 different modes defined in AVC: vertical horizontal DC diagonal down right and “same as luma”. Statistics show that the “same as luma” mode is frequent used but in AVC this mode is encoded using more bits than other modes during entropy coding therefore the coding efficiency is decreased. Accordingly a modified binarization/codeword assignment for chroma intra mode signaling is able to be utilized for high efficiency video coding (HEVC) the next generation video coding standard.
