IMAGE DECODER WITH CONTEXT-BASED PARAMETER BUFFER

摘要

According to some embodiments, a first value of a first parameter type is received in connection with a macroblock that represents a portion of an image. The macroblock may be divided into a first set of sub-portions, and different values of the first parameter type may be associated with different sub-portions of the first set. The first value may then be stored in a context buffer that includes a first context area associated with the first parameter type and a second context area associated with a second parameter type. The first context area might be, for example, adapted to store fewer values for each parameter type as compared to the second context area.
