Embodiment Construction

[0109] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0110] In the embodiment of the present invention, the networking of the video conference is as follows: figure 2 As shown, the video conference is completed jointly by multiple network elements, and the multiple network elements include: Service Management Center (Service Management Center, SMC) 20, Switching Center (SwitchCenter, SC) 21, MCU 22, conference room terminal 23, soft terminal 24. Auxiliary soft terminal 25.

Abstract

The invention relates to the technical field of video conference, and discloses an auxiliary flow transmission method and an auxiliary flow transmission device in order to ensure that the secret of a video conference terminal sending an auxiliary flow does not leak. According to the method, an MCU receives a first auxiliary flow sent by a first terminal, determines that the first auxiliary flow carries an encryption protection identifier, replaces the first auxiliary flow with a second auxiliary flow, and sends the second auxiliary flow to a second terminal without the auxiliary flow viewing permission. Thus, an auxiliary flow sent by a video conference terminal is not viewed by unwanted terminals, and leakage of the secret of the video conference terminal is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of video conferencing, in particular to a method and device for auxiliary stream transmission. Background technique [0002] The video service is a multimedia service that integrates information such as voice, image, and data for long-distance transmission. The service provided by the video service is video conferencing. Such as figure 1 As shown, in the prior art, when there are more than two participating terminals, they must be controlled through a multipoint control unit (MCU), and all participating terminals must be connected to the MCU through a standard interface. The terminal needs to be connected to the MCU through a communication network, and the physical transmission channel can be optical fiber, cable, etc. [0003] In a video conference, a video conference terminal in a certain site sends the main stream and secondary stream to terminals in other sites through the MCU. Among them, the...
