Embodiment Construction

[0022] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0023] Fig. 1 is a schematic diagram of the real-time video and image transmission technology of the present invention for video scene area division and parameter marking with only one information change area. As shown in Figure 1, for a video stream or image collection, there is only one information change area in the scene. The scene is divided into background information part [1] and information change area [3]. In order to restore the original scene information at the information receiving end, it is also necessary to record the relative position information [5] of the information change area [3] in the scene and the rectangular area side length parameters [2], [4] of the information change area [3]. . When shooting a video stream in this scene, it is only necessary to record a piece of background in...

Abstract

This invention puts forward a real time transmission technology of video images, which divides a video information region in a video scene into an unchanged background information region and a local region generating changed information, and only one time of collection, storage and transmission is needed for the collection of unchanged information in a video conference system, yet continuous video flows are generated to the local region generating changed information and positions and sizes of the local region are generated as the parameters to collect, store and transmit it and only one time is needed. Complete scene information is re-set up based on the received background information, continuous video flows of the local region generating changed information and the position and size parameters, which can reduce information transmission in the video and image transmission system.

Description

technical field [0001] The invention relates to the use of image digitization technology and image information processing technology to divide the video information area in the video scene into the unchanged background information area and the local area where the information changes. Different information areas adopt different processing methods to effectively reduce the video information. The information transmission volume in the conference system is an effective technology to realize the real-time video conference system. Especially in the environment where there are relatively few moving areas in video scenes such as video conferencing systems and film and television drama shooting, it can greatly reduce the data volume of video information and improve the transmission speed of video information in the network. It belongs to the field of image information processing technology and information transmission technology. . Background technique [0002] In today's society, ...
