Abstract  Abstract

A video quantization parameter encoder comprises: a prediction unit 11 for generating a predicted quantization parameter from a past reconstructed quantization parameter; a computing unit 12 for generating a delta quantization parameter from a quantization parameter and the predicted quantization parameter; quantization parameter encoding unit 13 for binary arithmetic encoding a first bin indicating whether or not the delta quantization parameter is significant; a sign bin indicating whether the delta quantization parameter is positive or negative and other bins indicating an absolute value of the delta quantization parameter in the case where the delta quantization parameter is significant; and adder for generating a re constructed quantization parameter by adding a predicted quantization parameter to the delta quantization parameter wherein the quantization parameter encoding unit 13 performs the binary arithmetic encoding using no context for the sign bin using a first context for the first bin and using a context different from the first context for the other bins.
