NON-UNIFORM EXPONENTIAL-GOLOMB CODES FOR PALETTE MODE CODING

摘要

In an example, a method of decoding video data using palette mode may include receiving a palette mode encoded block of video data of a picture. The method may include receiving encoded palette mode information for the palette mode encoded block of video data. The encoded palette mode information may be encoded according to a kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme and includes a unary prefix code word and a suffix code word. The method may include entropy decoding the encoded palette mode information using the kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme. The kth order non-uniform TEGk coding scheme is different from a kth order exponential-Golomb (EGk) coding scheme and a kth order truncated exponential-Golomb (TEGk) coding scheme. The method may include decoding the palette mode encoded block of video data using the decoded palette mode information.

1. A method of decoding video data using palette mode, the method comprising:
receiving, from an encoded video bitstream, a palette mode encoded block of video data of a picture; receiving, from the encoded video bitstream, encoded palette mode information for the palette mode encoded block of video data, wherein the encoded palette mode information is encoded according to a kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme and includes a unary prefix code word and a suffix code word; entropy decoding the encoded palette mode information using the kth order non-uniform truncated exponential-Golomb (TEGk) coding scheme, wherein the kth order non-uniform TEGk coding scheme is different from a kth order exponential-Golomb (EGk) coding scheme and a kth order truncated exponential-Golomb (TEGk) coding scheme; and decoding the palette mode encoded block of video data using the decoded palette mode information.
