An initializing method and a decoding method of a context

Title:

An initializing method and a decoding method of a context

Document Type and Number:

Japanese Patent JP5938119

Kind Code:

B2

Abstract:

Systems and methods for context model initialization in entropy encoders and decoders are disclosed. In some exemplary embodiments, the context model may be reset when a current macroblock is the first one in a row, the number of bins or bits are processed within the entropy slice.
