METHOD AND APPARATUS FOR DETERMINING CODING FOR COEFFICIENTS OF RESIDUAL BLOCK, ENCODER AND DECODER |
摘要 |
Provided are a method and apparatus for determining coding for coefficients of a residual block, an encoder and a decoder. The method includes generating a residual block by subtracting a motion-compensated prediction block from the current block; frequency-converting coefficients of the residual block into frequency coefficients; frequency-converting coefficients of the motion-compensated prediction block into frequency coefficients; and determining coding for each of the coefficients of the frequency-converted residual block based on the coefficients of the frequency-converted prediction block. Accordingly, the amount of information transferred to a decoder can be reduced by not coding some coefficients of the residual block.
