HIGH SPEED SCALABLE VIDEO CODING DEVICE AND METHOD USING MULTI-TRACK VIDEO

摘要

The present disclosure relates to a Scalable Video Coding (SVC) video decoding method, including receiving a bit stream for layer videos, determining an encoding mode information and a prediction information for a macroblock of a lower layer video from among the layer videos; performing prediction of the macroblock of the lower layer video by using the encoding mode information and the prediction information for the macroblock of the lower layer video, obtaining an encoding mode information for a macroblock of a upper layer video from among the layer videos, determining a prediction information of the macroblock of the upper layer video based on a macroblock of the lower layer video which is corresponding to the macroblock of the upper layer video, and performing inter-layer prediction of the macroblock of the upper layer video by using the encoding mode information and the prediction information for the upper layer video.

1. A Scalable Video Coding (SVC) video decoding method, comprising:
receiving a bit stream for a plurality of layer videos; determining an encoding mode information and a prediction information for a macroblock of a lower layer video from among the plurality of layer videos; performing prediction of the macroblock of the lower layer video by using the encoding mode information and the prediction information for the macroblock of the lower layer video; obtaining an encoding mode information for a macroblock of a upper layer video from among the plurality of layer videos; when the encoding mode information for the macroblock of the upper layer video indicates an inter-layer prediction, determining a prediction information of the macroblock of the upper layer video based on a macroblock of the lower layer video which is corresponding to the macroblock of the upper layer video; and performing inter-layer prediction of the macroblock of the upper layer video by using the encoding mode information and the prediction information for the upper layer video.
