Video conference screen sharing implementation device

Abstract

The invention relates to a video conference screen sharing implementation device, and the device is characterized in that the device comprises a transmitter which is connected with a terminal which needs to share a screen; the interior of the transmitter is provided with an SVC coding module, and the SVC coding module is used for carrying out the SVC coding of a to-be-shared video image transmitted by the terminal which needs to share the screen, and forming an SVC sharing video stream; the device also comprises a receiver which is connected with the transmitter and is also in in communication connection with a video conference server; the receiver is used for receiving the SVC sharing video stream transmitted by the transmitter, and transmitting the SVC sharing video stream to the video conference server; the video conference server enables the received SVC sharing video stream to be transmitted to the terminals of other video conference participants. Compared with the prior art, the device is advantageous in that the device is simple in operation; the video conference server does not need to carry out the decoding and coding of the SVC sharing video stream, and just needs to transmit the received SVC sharing video stream to the terminals of other video conference participants; the method is light in burden, and has no processing delay.

Description

technical field [0001] The invention relates to a device for realizing screen sharing of a video conference. Background technique [0002] A general video conferencing system includes MCU multipoint controller (an implementation of video conferencing server), meeting room terminals, PC desktop terminals, telephone access gateways, network gatekeepers and other parts. Various terminals are connected to the MCU multi-point controller for centralized exchange to form a video conferencing network. [0003] The MCU multi-point controller is the core part of the video conferencing system, providing users with connection services for group conferences and multi-group conferences. The meeting room terminal is provided for the user's meeting room. The meeting room terminal has its own camera and remote control keyboard, which can be displayed through a TV or projector. Users can choose different devices according to the size of the meeting place. Generally, meeting room equipment ha...

AI Technical Summary

Problems solved by technology

[0006] 1. The hardware video input interface (HDMI or VGA) requires a connecting cable, which is troublesome to use;

[0007] 2. Screen sharing software is often built into the hardware or software of the conference room terminal, and it is inconvenient to manage multiple media streams (audio, video) at the same time;

[0008] 3. The computer for screen sharing needs to be connected to a wireless network such as Wi-Fi to access the conference, which is not convenient and safe

[0009] 4. If the video conferencing server uses an MCU multi-point controller, the shared video stream needs to be decoded by the MCU multi-point controller and then re-encoded, which consumes a lot of processing resources, is uneconomical, and brings additional delays
