Abstract
Decoding a symbol may include decoding a binary codeword from an encoded video stream and decoding a symbol from the binary codeword, wherein the binary codeword is a binary codeword generated by an encoder for the symbol by determining a truncated rice prefix for a symbol, the symbol having a parameter variable, in response to a determination that the parameter variable is greater than zero, determining a truncated rice suffix for the symbol and concatenating the end of the truncated rice prefix with the truncated rice suffix to determine a main prefix, and in response to a determination that the main prefix is the same as a comparison string, wherein the comparison string is a bin string with each bin set to “1”, determining a main suffix for the symbol by concatenating the end of the main prefix with the main suffix to determine the binary codeword for the symbol.
