Abstract

DC60 (24/10/55) Provided here is a set of encoder movies to increase the compression ratio. Video signals while maintaining a high image quality. To reduce the number of bits Required for the residual block to a minimum. Coefficient of processed conversion Quantities are classified into more than one subset according to the block size. For transforms and coefficients of a quantization-treated transformation that are not equal to zero of Each subset will be scanned and encrypted. In addition, the prediction modality within the image of The current block is based on the reference pixel obtained by filtering the current block's reference pixel. As a result, the amount of information required for the current block residual block can be minimized. Provided here is a set of video encoding machines to increase the compression ratio.
