Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] Such as figure 1 As shown, it is a schematic flow chart of the video screen switching method in an embodiment of the present invention, and the steps of the method are as follows:

[0020] S11. Store the received first video data in a preset first buffer, and record the address of the first buffer;

[0021] The screen switching method of the present invention is suitable for MCU-based video conferencing systems, such as figure 2 Shown is the architecture diagram of the video conferencing system. The MCU server is the server in the video conferencing system, which is responsible for exchanging video data and sending control commands. Terminals T1~Tn are the terminals in the video conferencing system, responsible for sending or receiving video data. And analyze the c...

Abstract

The invention relates to a video field and provides a video image switching method. The video image switching method comprises the following steps of: storing received first video data in a pre-set first buffering area, and recording an address of the first buffering area; outputting a first video according to the address of the first buffering area; storing received second video data in a pre-set second buffering area, and recording an address of the second buffering area; and when a pre-set switching order is received, outputting a second video according to the address of the second buffering area. The invention correspondingly provides a video image switching system. With the adoption of the video image switching method and the video image switching device provided by the invention, the problems that the conventional video conference system usually has phenomena of pixelizations and blurred screens can be solved; and the image switching effect is relatively good.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to a video screen switching method and a video screen switching system. Background technique [0002] The existing video conferencing system based on MCU (Multipoint Control Unit, multipoint control unit) includes MCU server and multiple terminal devices. When more than three terminals participate in the video conference, video switching may occur; for example, When one terminal plays the multiplexed video of the other two terminals, when this terminal wants to play the high-definition video of the other terminal, it needs to switch from the multiplexed video to the high-definition video. [0003] The traditional screen switching process is that when a terminal sends a request to the MCU server to switch the high-definition mode of another terminal, the terminal immediately switches to the single-channel high-definition video mode, and stops receiving multiple-channel...
