METHOD, DEVICE, AND PROCESSING SYSTEM FOR VIDEO ENCODING AND DECODING

摘要

A method, device, and processing system for video encoding and decoding. The method comprises: producing background frames for a video sequence to be encoded; encoding image frames and the background frames of the video sequence to be encoded to produce respective video streams; and, inserting into the video streams identifications of whether or not each frame of image is to be displayed when decoded. By producing the background frames for the video sequence to be encoded, encoding the video to be encoded into video streams of the image frames and of the background frames, and adding identifications to the video streams to determine whether or not corresponding images need to be displayed when decoded, non-display frame encoding is supported at a stream layer to support background image reference, encoding efficiency is increased, and display of images that do not need to be displayed is prevented during display, thus increasing display efficiency.
