Abstract
(EN)
Provided are a video processing method and apparatus. The method comprises: if the size of a current block does not meet a preset condition, using a motion vector of precision of one of whole pixel precision and sub-pixel precision to perform inter-frame prediction on the current block; if the size of the current block meets the preset condition, using a motion vector of the whole pixel precision to perform inter-frame prediction on the current block; and if the size of the current block meets the preset condition, prohibiting the use of a motion vector of the sub-pixel precision to perform inter-frame prediction, rather than completely prohibiting the current block from executing the inter-frame prediction as in the related art, so that data throughput can be reduced, and coding performance is guaranteed as far as possible.

L'invention concerne un procédé et un appareil de traitement vidéo. Le procédé consiste : si la taille d'un bloc courant ne satisfait pas une condition prédéfinie, à utiliser un vecteur de mouvement de précision de l'une d'une précision de pixel entier ou d'une précision de sous-pixel pour effectuer une prédiction inter-trame sur le bloc courant; si la taille du bloc courant satisfait la condition prédéfinie, à utiliser un vecteur de mouvement de la précision de pixel entier pour effectuer une prédiction inter-trame sur le bloc courant; et si la taille du bloc courant satisfait la condition prédéfinie, interdire l'utilisation d'un vecteur de mouvement de la précision de sous-pixel pour effectuer une prédiction inter-trame au lieu d'interdire entièrement au bloc courant d'effectuer la prédiction inter-trame comme dans l'état de la technique, ce qui réduit le débit de données et garantit au maximum la performance de codage.

提供一种视频处理方法和装置。该方法包括:如果当前块的尺寸不满足所述预设条件,采用整像素精度和亚像素精度中的一种精度的运动矢量对所述当前块进行帧间预测;如果当前块的尺寸满足所述预设条件,采用整像素精度的运动矢量对所述当前块进行帧间预测。如果当前块的尺寸满足所述预设条件,则禁止其采用亚像素精度的运动矢量进行帧间预测,而非像相关技术那样完全禁止当前块执行该帧间预测,从而可以在降低数据吞吐量的同时尽量保证编码性能。
