Abstract
A method for processing a 2N×2N block under intra-prediction includes: utilizing an intra-prediction unit for performing intra-prediction upon the 2N×2N block by utilizing a plurality of prediction modes, and accordingly generating a plurality of intra-prediction results respectively corresponding to the prediction modes, wherein N is a positive integer greater than four, and a number of the prediction modes is greater than four; and determining a target intra-prediction result from the intra-prediction results.
Claims8
A method for processing a 2N×2N block under intra-prediction, comprising:
- determining macroblock type information and coded block pattern (cbp) information corresponding to the 2N×2N block, wherein N is a positive integer greater than four;
- and
- utilizing a coding unit for generating a codeword with only the macroblock type information and the cbp information coded therein.
A method for processing a 2N×2N block under intra-prediction mode, comprising:
- utilizing a checking unit for checking if a coded block pattern (cbp) corresponding to the 2N×2N block is equal to zero, wherein N is a positive integer greater than four;
- and
- when the cbp is equal to zero, not transmitting information of a delta quantization parameter (delta QP).
