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

Embodiment approach

[0071] To sum up, the present invention discloses a method for connecting a PSTN phone to a conference TV terminal through Bluetooth, which belongs to the field of multimedia audio transmission and involves voice access in a conference TV. It utilizes mature Bluetooth technology to realize audio The wireless transmission of data in the Bluetooth conference TV voice terminal and the Bluetooth cordless phone voice gateway. The main implementation plan is as follows:

[0072] 1. The Bluetooth conference TV voice terminal interacts with the Bluetooth cordless phone voice gateway.

[0073] 2. The Bluetooth conference TV voice terminal encodes the voice data in the conference and transmits it to the Bluetooth cordless phone voice gateway in the form of data signals. After processing, the Bluetooth cordless phone voice gateway establishes voice communication with the PSTN phone.

[0074] 3. There are two ways to establish a connection between the Bluetooth conference TV voice termin...

Abstract

The audio data transmission system includes following parts: blue teeth voice gateway (BTVG) in use for carrying out seeking conference TV terminal (CTVT), and establishing blue teeth communication link (BTCL) to CTVT; through BTVG, CTVT passing BTCL carries out voice communication to public telephone switching network. Taking full advantage of wireless communication in close range of mature blue teeth technique, and using function of BTVG, the invention makes BTVG possible to reduce part of hardware interface so as to provides features: more deploying degree of freedom, without need of considering restraint of telephone line, and more convenient to use and install.

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...
