Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0022] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0023] The videoconferencing endpoint is capable of operating at asymmetrical video bit rates, frame rates, and image resolutions (if multiple image resolutions are supported). For example, a terminal with 720P capability is allowed to send 264CIF video images and accept 720P images. In this case, the terminal is referred to as a terminal entering the transcoding state or a transcoding terminal in the embodiment of the present invention. In symmetric mode, a terminal that has the same ability to receive and send video is called a terminal that exits the tr...

Abstract

The invention provides a method for video monitoring of a terminal of a videoconferencing system, a device for video monitoring on the terminal of the videoconferencing system and a system for video monitoring on the terminal of the videoconferencing system and a system. The method includes the steps that firstly, after a multipoint conference is successfully convened, a PC (personal computer) control console receives attribute information of a monitored terminal attending the conference and transmitted by an MCU (microprogrammed control unit), secondly, the PC control console judges whether a video format of images currently transmitted by the monitored terminal is high in definition or not according to the attribute information of the monitored terminal, and the monitored terminal is not a broadcaster or a broadcaster responsible terminal of the current conference, thirdly, the PC control console commands the monitored terminal to enter the transcoding state by the aid of the MCU and transmits transcoded images to the PC control console, and finally, the PC control console decodes and displays the received images. By the aid of the method, video monitoring on multipath high-definition terminals is realized without improving the decoding capacity of the PC control console.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a video monitoring method, system and device for a terminal of a video conference system. Background technique [0002] In a large video conference system, in order to ensure the quality of the conference, it is necessary to monitor the real-time multi-point conference venue. At present, there are mainly two monitoring methods for video conference multi-point conference venues: image platform monitoring and PC console remote monitoring. [0003] Among them, the image station monitoring means that the Multipoint Control Unit (MCU for short) directly outputs the audio and video stream data from the terminal to the image station device without processing, and the image station device receives the audio, video and video data received from the MCU. The video stream data is processed and displayed on the TV wall, large screen or similar equipment to realize the monitoring of the cur...
