Embodiment Construction

[0033] The present invention synthesizes multiple pictures into more than two video streams, each video stream is respectively a multi-picture video (including a special case of a single picture), and each video stream is displayed on a different display. In this way, under the same total number of sub-pictures, each sub-picture has a larger display area available, and the user can watch a larger sub-picture, thereby improving the quality of video experience.

[0034] As shown in Figure 1, the method of the present invention comprises the following steps:

[0035] Step 110, the terminal participating in the communication establishes a connection with the MCU providing multipoint communication service or the built-in MCU terminal.

[0036] Wherein, the connection between the terminal and the MCU or the built-in MCU terminal can be established using, but not limited to, one of ITU-TH.323, ITU-T H.320, and IETF SIP protocols.

[0037] In the connection establishment process, the...

Abstract

The invention provides a multi-screen multi-picture realization method and a system in a video conferencing system. The video conferencing system comprises a multipoint control unit and a plurality of terminals; the method includes the following steps that: (a) the terminals establish connection with the multipoint control unit and send local video streams to the multipoint control unit; (b) the multipoint control unit composes the input video streams of the terminals into a plurality of output video streams; (c) the multipoint control unit sends the output video streams to the terminals, wherein the content of each output video stream is a multi-picture video composed by one or a plurality of input video streams; (d) the terminals display the output video streams on a plurality of displays after reception. According to the method of the invention, the terminals taking part in communication can use a plurality of displays to display video images of a plurality of far end conference rooms, and users can see more and larger video images of the far end conference rooms, thereby improving the video experience of the users, strengthening the communication effects of users and promoting the use value of the system.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a method and system for realizing multi-screen and multi-picture in a video conferencing system. Background technique [0002] The video conferencing system is a multimedia communication system that supports voice, video and data communication, and it includes a video conference terminal, MCU (Multipoint Control Unit, multipoint control unit) and some other equipment. [0003] The video conferencing systems currently on the market generally conform to the ITU-T H.320 (International Telecommunication Union Telecommunication Standard H.320) or ITU-T H.323 standard, and there are also systems that conform to the IETF SIP (Internet Engineering Task Force Session Initiation Protocol) standard . [0004] The terminal is the device used by the user. The terminal contains a codec. The codec is responsible for completing the compression encoding and decoding of sound, video and other me...
