Embodiment Construction

[0049] The video conferencing system includes MCU and various terminals. According to the needs of the meeting, the MCU decodes, adapts, and encodes the video data received from a specific terminal device, integrates the conference video and sends it to each terminal.

[0050] In related technologies, the video conferencing system usually adopts the full encoding and full decoding mode. The MCU receives the video data of each terminal, decodes all the video data, and then encodes the decoded data according to the conference layout mode of each terminal, and sends corresponding information to each terminal. send encoded data. However, since the video data of all terminals needs to be decoded, adapted, and encoded, each terminal needs to be configured with a corresponding encoder, which consumes a lot of computing resources and increases the delay time of the video conference.

[0051] Based on this, in various embodiments of the present invention, a decoder is used to decode t...

Abstract

The invention provides a data transmission method and device, electronic equipment and a storage medium. The data transmission method comprises the following steps: decoding a first video stream uploaded by each terminal in N terminals by adopting M decoders, wherein M and N are positive integers, M is smaller than or equal to N, and N is larger than or equal to 2; encoding all the decoded video streams into a second video stream based on a first encoder in a set time period in the video conference process; and sending the second video stream to each of the N terminals. In the video conference process, all terminals are enabled to display the same picture in the set time period, so that coding computing resources can be saved, and the transmission delay time of the video conference can be reduced.

Description

technical field [0001] The invention relates to the technical field of video conferencing, in particular to a data transmission method, device, electronic equipment and storage medium. Background technique [0002] The video conferencing system includes a multipoint control unit (Multi Control Unit, MCU) and various terminals. According to the needs of the meeting, the MCU decodes, adapts, and encodes the video data received from a specific terminal device, integrates the conference video and sends it to each terminal. [0003] In related technologies, the video conferencing system usually adopts the full encoding and full decoding mode. The MCU receives the video data of each terminal, decodes all the video data, and then encodes the decoded data according to the conference layout mode of each terminal, and sends corresponding information to each terminal. send encoded data. However, since the video data of all terminals needs to be decoded, adapted, and encoded, each ter...
