Method of determining binary codewords for transform coefficients

A video decoder comprising:

• a memory configured to store a symbol;
• and
• a processor coupled with the memory, wherein the processor is configured to determine the symbol from a binary codeword by:
• decoding the binary codeword from an encoded video stream;
• and
• decoding the 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 the symbol;
• in response to a determination that a parameter variable is greater than zero, determining a truncated rice suffix for the symbol and determining a main prefix by concatenating the end of the truncated rice prefix with the truncated rice suffix;
• 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 and determining the binary codeword by concatenating the end of the main prefix with the main suffix.

A non-transitory computer readable medium containing program instructions for determining a symbol from a binary codeword, that, when executed by a processor, facilitate performance of operations, comprising:

• 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:
• receiving a symbol, a parameter variable, and a maximum symbol value associated with the parameter variable;
• determining a truncated rice prefix for the symbol, in response to a determination that the parameter variable is greater than zero, determining a truncated rice suffix for the symbol and determining a main prefix by concatenating the end of the truncated rice prefix with the truncated rice suffix;
• 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 and determining the binary codeword for the symbol by concatenating the end of the main prefix with the main suffix.
