Problems solved by technology

[0009] However, video polling has a disadvantage, that is, when the list of terminals to be polled is very long, it will take a long time to perform a complete round of video polling. For example, taking a conference with 60 terminals as an example, assuming that each The video of each terminal is watched for 5 seconds, and it takes about 5 minutes to perform a round of query.
In this way, the polling time is too long, which affects the efficiency of users participating in meetings

Embodiment 1

[0047] A system supporting multi-picture polling function, as shown in Figure 1(a), the system includes an MCU, a WEB management server and several terminals connected to the MCU respectively, and the WEB management server is also connected to the browser client . in:

[0048] Browser client, through which the user accesses the WEB management server;

[0049]The WEB management server transmits the browser client instructions to the MCU. In this embodiment, the WEB management server further includes a multi-screen polling interface, and the browser client interacts with the MCU through this interface, wherein the browser The client can initiate multi-screen polling operations to the MCU through this interface, such as setting polling terminals, polled terminals, and multi-screen layout operations;

[0050] MCU is used to synthesize multi-picture video data, and completes the multi-picture polling function according to the instruction of the browser client. In this embodiment,...

Embodiment 2

[0069] Next, another system that supports the multi-screen polling function is described, as shown in Figure 2(a), this system is different from the system proposed in Embodiment 1 in that the multi-screen polling human-computer interaction interface is built into the terminal In the device, the WEB management server and browser client are omitted. in,

[0070] The terminal has newly added the function of requesting multi-screen polling operation from the MCU device, that is, the user inputs various polling operation instructions to the MCU through the multi-screen polling interface on the terminal, and the terminal with the multi-screen polling function can also be used as a Polling the terminal.

[0071] The process of the above-mentioned system processing multi-screen polling is that the user controls the multi-screen polling operation through the terminal, which specifically includes the following steps, as shown in Figure 2(b):

[0072] Step 201: The user starts a multi...

Abstract

The invention discloses a polling method and a polling system of a videoconference system, relating to the videoconference field. The polling method of the videoconference system provided by the invention comprises the following steps that: in the process that a user starts the polling operation of the videoconference system, after grouping all polled terminals, the user orderly initiates polling requests for each group of polled terminals; a system receiving the polling requests synthesizes the video data of each group of polled terminals respectively into multi-picture video data and sends the multi-picture video data to a polling terminals; after receiving the multi-picture video data, the polling terminal orderly decodes and display, so as to realize multi-picture video polling. The invention also discloses a system for realizing polling in the videoconference system. A technical proposal of the invention shortens the traversal time of the video polling for all or partial terminals in a conference, thereby improving conference efficiency.

Description

technical field [0001] The invention relates to the field of video conferencing, in particular to a polling method and system for a video conferencing system. Background technique [0002] A video conferencing system is a multimedia communication system that supports voice, video and data communication, and it includes a video conference terminal, a multipoint control unit (MCU, Multipoint Control Unit) and other devices. The video conferencing systems currently on the market generally conform to the ITU-T H.320 or ITU-T H.323 standards, and there are also video conferencing systems conforming to the IETF SIP standard. [0003] Among them, the terminal is the device used by the user. The terminal contains a codec, which is responsible for the compression, encoding and decoding of sound, video and other media. The terminal is also connected with a microphone, camera, display, and sound playback subsystem to complete the sound. 1. Video input and output, the terminal also inc...
