Embodiment Construction

[0012] The present invention normalizes the format of the video information, so that various direct operations can be performed on the basis of the multi-channel data. The different formats referred to here are mainly resolution formats. Because it is necessary to ensure that the relative resolution ratios of different source videos remain unchanged during the calculation process, it is necessary to identify the resolution information in advance and then normalize it. . In principle, the resolution of the result should not be smaller than the maximum resolution of the input video, otherwise it will affect the quality of the video.

[0013] Then the normalized multi-channel video is operated and encoded by a common compression encoding method.

[0014] For the transmission link, it is necessary to use the RTP and RTCP protocols to achieve the purpose of bandwidth adjustment and real-time guarantee.

[0015] As we all know, RTP is a real-time transmission protocol that provide...

Abstract

The invention discloses a video information live transmission, storing and deacidizing method in the internet, which is characterized by the following: the video information is catched and digitalized by the video trap; the screen video information is catched by screen trap; two pathes of datas are sent to agitator and carried out normalization treatment; the calculation result is coded; the accumulator saves the coded message according to the standard video flow media file layout; the coded message is transdered in network by transceiver; the transceiver provides transmitting-receiving media information in network; the received video flow data is delivered to the video restorer and deacidized according to the video code format; the deacidized data is presented on the persent device.

Description

technical field [0001] The invention relates to a device and method for real-time transmission, storage and restoration of video information from different sources and in different formats on the Internet. Background technique [0002] In recent years, the technology of transmitting video and audio information in the local area network has been increasingly adopted by various applications, but there is no effective solution to the mixing of video information from different sources and different formats, encoding, storage and transmission restoration. . [0003] Analyzing the root cause of this problem will reveal that in the above process, video information in different formats is mixed, encoded, saved, and streamed media in the network is sent, received, and restored, while meeting the real-time requirements. It is necessary to integrate encoding technology, Transmission technology, storage technology and original technology. Contents of the invention [0004] The objec...
