Embodiment Construction

[0019] In order to understand how video conferencing works, a brief introduction to the composition of video conferencing is given. Video conferencing is mainly composed of three parts of key equipment: the first part is peripheral equipment, which is divided into acquisition and display equipment, such as cameras and MICs are acquisition equipment, and monitors or TVs are display equipment; the second part is video terminal equipment , the main functions are video compression and decompression and signaling call processing, video terminals are placed in various venues, pure voice IP phones, PSTN phones, etc. can also be attributed to this type of equipment; the third part is the central processing equipment, called MCU, Multi-point control unit, this type of equipment is placed in the center of the system, and is used to schedule and control conferences, convert code streams, and form multi-screens, etc. For each terminal joining a video conference, there is a uniquely assign...

Abstract

The invention relates to a method for displaying a pure voice terminal image in a video session. The method comprises the following steps of: (1) establishing a session voice terminal library on a micro-programmed control unit (MCU); (2) allowing the MCU to search for human face image code stream of a voice terminal user according to a preset rule; (3) allowing the MCU to transmit corresponding same protocol human face image code stream and audio stream together to each terminal according to the protocol supporting situation of the current session; and (4) after each terminal receives the human face image code stream and the audio code stream, decoding the received human face image code stream and audio code stream and displaying and playing the decoded human face image code stream and audio code stream on a display device and a voice playing device respectively. In the method for displaying the pure voice terminal image in the video session of the invention, a pure audio terminal is added into the video session, so that other terminals can see the image of the audio terminal, session effect is enhanced greatly and universal practical value is achieved.

Description

technical field [0001] The invention relates to the field of multimedia communication, in particular to a method for displaying pure voice terminal images in a video conference. Background technique [0002] In video conferencing, terminals are generally terminals that support video, but in certain cases, there may also be voice-only terminals that do not support video, such as IP phones, PSTN phones, or mobile phones. When these terminals join the video conference, they can only hear the sound, but not see the shape, which greatly damages the intuitiveness of the video conference. Contents of the invention [0003] The purpose of the present invention is to provide a method for displaying a pure voice terminal image in a video conference, which can display the personal image of a pure voice terminal on other terminals in the video conference system. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A method for d...
