IMAGE ENCODING/DECODING DEVICE AND METHOD

摘要

A video decoding method includes: decoding a skip information indicating whether or not a current block to be decoded is a skip block; when the skip information indicates that the current block is the skip block, decoding motion information of the current block, determining a motion vector of the current block, and reconstructing the current block directly from a predicted block, without decoding information on residual signals of the current block; and when the skip information indicates that the current block is not the skip block, decoding prediction information of the current block from the bitstream, decoding information on a quantization parameter and transform coefficients which correspond to the current block, when at least one of the transform coefficients is not zero, reconstructing residual signals from the transform coefficients and reconstructing the current block based on the prediction information and the reconstructed residual signals.

1. A video decoding method, comprising:
decoding, from a bitstream, a skip information indicating whether or not a current block to be decoded is a skip block; when the skip information indicates that the current block is the skip block,
decoding motion information of the current block from the bitstream, and thereby determining a motion vector of the current block, andreconstructing the current block directly from a predicted block predicted using the motion vector of the current block, without decoding information on residual signals of the current block; and when the skip information indicates that the current block is not the skip block,
decoding prediction information of the current block from the bitstream,decoding, from the bitstream, information on a quantization parameter and transform coefficients which correspond to the current block, when at least one of the transform coefficients is not zero,reconstructing residual signals from the transform coefficients, by using the information on the quantization parameter, andreconstructing the current block based on the prediction information and the reconstructed residual signals.
