FIELD: physics.SUBSTANCE: way of encoding video data contains the context definition for entropy coding bin value that indicates the last significant block coefficient using index referred to bin which feature creates a context index on the context by bin index right shift on the value of k and adding the right shifted values to the value of the offset. Define the offset value according to the formula: offset=3*n+((n+1)>>2). The value of k is determined according to the formula: k=(n+3)>>2. And where the value of n is determined according to the formula: n=(log(block_size)-2). And where the value of block_size contains a value indicating the size of the block and encoding the named bin using a specific context.EFFECT: increasing the efficiency of using the memory of a video encoder video decoder.21 cl 5 dwg 10 tbl
