Abstract： |
A method for quickly selecting mode of interframe prediction code includes calculating price function under skip mode, calculating price function of macroblock, calculating SAD value of four 8x8 sub-macroblock on said macroblock by applying full-sampling mode, obtaining relevant price function of said macroblock by carrying out 16x8 and 8x8 block motion search on said macroblock and selecting interframe prediction code mode with minimum price function to carry out motion compensation of next stage. |
