Problems solved by technology

The current video conferencing system realizes two-way video conferences between venues through the IP network. Its disadvantage is that it occupies a lot of network bandwidth resources, and it is easy to cause video signal packet loss, and it is difficult to achieve real high-definition video signal transmission.
At the same time, the deployment and implementation of large-scale video conference venues is expensive, and it is difficult to promote and apply, which has limitations.

Embodiment 1

[0016] Such as figure 1 As shown, this embodiment describes that the video conferencing set-top box terminal is an intelligent video conferencing multimedia terminal. It includes a central processing unit 1, a tuner 2, an audio and video signal input interface 3, a key indicator light module 4, an LED display module 5, a network return module 6, an audio and video signal output interface 7, a power supply module 8 and a casing 9. The tuner 2 receives the front-end digital TV video conferencing signal through the HFC network, and the tuner 2 converts the RF signal into an intermediate frequency signal. The central processing unit 1 demodulates and demultiplexes the intermediate frequency signal, and divides the signal into video stream, audio stream and data stream. Whether the group of information contains video conference information can be identified according to the information in the data stream. The audio signal input interface 3 is connected to an external audio and vi...

Abstract

The invention designs a video conferencing set-top box terminal. The terminal comprises a central processor, a tuner, a power supply module, and an audio and video signal output interface. The tuner, the power supply module, the audio and video signal output interface are all connected with the central processor. The terminal is characterized in that an audio and video input interface and a network backhaul module further are also included. The audio and video input interface is connected with the network backhaul module through the central processor. The terminal of the invention is characterized in that: the set-top box has the audio and video collection and conversion function, can return the collected audio and video through the network, and can be applied to two network models.

Description

technical field [0001] The invention relates to a set-top box, which is a video conference set-top box terminal that can be used for video conferences. Background technique [0002] Video conferencing is a communication method that supports real-time information exchange and collaborative work between people at a distance. Video conferencing integrates the transmission of voice, data, and images, so that users can visit the scene without leaving home. The current video conferencing system implements two-way video conferences between venues through the IP network. Its disadvantages are that it occupies a lot of network bandwidth resources, and it is easy to cause video signal packet loss, and it is difficult to achieve real high-definition video signal transmission. At the same time, the cost of deployment and implementation of large-scale video conferencing venues is relatively high, and it is difficult to popularize and apply, which has limitations. Contents of the inven...
