Audio data transmission method for conference TV terminal

Abstract

The audio data transmission method includes following steps: carrying out blue teeth seeking between blue teeth voice gateway (BTVG) and conference TV terminal (CTVT); after security authentication is passed, the method establishes blue teeth communication link (BTCL) between BTVG and CTVT; through BTCL, CTVT passing BTVG carries out voice communication with public telephone exchange network for voice. Taking full advantage of superiority of radio communication in close range of mature blue teeth technique, the invention makes CTVT reduce part of hardware interface by using BTVG provided from cordless telephone. Advantages are: larger degree of freedom for deployment, unnecessary considering restriction of telephone line, and convenient installation and use.

Description

technical field [0001] The invention relates to the field of data communication, in particular to an audio data transmission method and system for a video conference terminal. Background technique [0002] At present, a video conference terminal generally consists of a host computer, peripherals and peripheral cables. Usually, the conference TV provides PSTN (Public Switched Telephone Network, public switched telephone network) telephone access technology, that is, the PSTN telephone dials and joins the conference, and conducts two-way communication through the PSTN voice signal. figure 1 It is a schematic diagram of the PSTN access mode in the video conference at present. [0003] At present, there are the following problems in the PSTN access mode in the conference TV: [0004] 1. Due to the use of telephone line access, the terminal is difficult to move due to the limitation of the telephone line, which limits the range of movement of the user. [0005] 2. The wired co...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the use of telephone line access, limited by the telephone line, it is difficult for the terminal to move, which limits the range of movement of the user

[0005] 2. The wired connection between the telephone line and the host increases the complexity of the device connection

[0006] 3. High requirements for system space, affecting the layout of the entire video conference system and the cleanliness of the environment

[0007] 4. The hardware interface of the telephone line must be added to the terminal, which increases the hardware cost of the equipment
