Video encoding and decoding method and device supporting retractable video browse

Abstract

The invention discloses a video encoding and decoding method and a device supporting retractable video browse. According to the invention, when an original video is encoded, a moving object flag bit, corresponding to the original video and obtained through video analysis and processing during the encoding, allows a decoding end to perform video decoding supporting the retractable video browse according to the moving object flag bit; and the device and the method provided by the invention decode the re-established original video and moving object flag bit at the same time, so the displayed start-stop time by the moving object at the decoding end can be rearranged according to the moving object flag bit, so as to realize retractable video play. The invention has the benefits that the storage efficiency of both the outline video and the original video is greatly improved, and the retractable browse of the moving objects appearing at different times and different places can be realized atthe same time.

Description

technical field [0001] The invention relates to the field of video analysis and processing and video codec, in particular to a codec method and device for fast browsing of video that supports scalable adjustment of moving object density in video. Background technique [0002] In recent years, with the rapid development of digital media, the public security situation has attracted widespread attention from the society and the public, and multimedia and security video data have exploded. The traditional time-consuming simple and original browsing method is far from meeting people's needs for accessing and querying video information. There are new ways to browse and view videos. [0003] The current video browsing methods can be divided into three categories: Video Summary, Video Skimming and Video Synopsis: [0004] 1. Video overview is a collection of images extracted from the original video to summarize the original video content, and these images representing the original...
