Video imaging preview method for video conference system

Abstract

The invention provides a video imaging preview method for a video conference system. The method comprises: all original video streams are received from a television wall server and a recording-broadcasting server network interface; the original video streams are decomposed and a video key frame is extracted and transmitted to a video preview page interface through an HTTP (Hyper Text Transport Protocol) protocol; decoding is performed by an H.264 decoder to generate YUV (Luma and Chroma) data; a preview video stream module performs secondary coding to the YUV data; a preview video file is generated from an H.264 preview video stream through a preview video stream sectionalizer, wherein the H.264 preview video stream is generated through secondary coding; a video preview page distributes the module to the preview video file to request to preview the video file through the HTTP; the preview video file is decoded as YUV data through the H.264 decoder; and the YUV data is drawn into a screen through a preview video stream broadcaster. According to the invention, a user is facilitated to perform video preview to a current server video stream at an operation floor, and each video stream can be combined and spliced, so that a server output display function is perfected, and user experience is enhanced.

Description

technical field [0001] The invention relates to a video imaging preview method used in a video conference system, belonging to the technical field of television / video communication. Background technique [0002] With the continuous development of video conferencing requirements, video wall servers and recording servers are more and more widely used in video conferencing systems. At the present stage, both the TV wall server and the recording and broadcasting server directly output the video stream input to the server, so the video images that users see are the original images of the MCU (Multipoint Control Unit) or the video terminal, and the video wall server and The operator of the recording server must use other video conferencing equipment to monitor the video conference. In this case, it is difficult to control the presentation of the conference, and it is not convenient to organize and save the video data after the conference. Therefore, the existing video wall se...

At the present stage, both the TV wall server and the recording and broadcasting server directly output the video stream input to the server, so the video images that users see are the original images of the MCU (Multipoint Control Unit) or the video terminal, and the video wall server and The operator of the recording server must use other video conferencing equipment to monitor the video conference. In this case, it is difficult to control the presentation of the conference, and it is not convenient to organize and save the video data after the conference.

Therefore, the existing video wall server and recording server cannot meet the control and use requirements of complex conferences
