Embodiment Construction

[0066] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0067] The present invention provides a transmission method of high-definition dual-stream video, referring to figure 1 , in one embodiment, the transmission method of the high-definition dual-stream video includes:

[0068] Step S11, the sending end sends the first video and the second video with a first predetermined code rate to the receiving end of the video conference terminal device;

[0069] In this embodiment, the video conferencing terminal equipment sender and receiver need to enable the dual-stream mode, and the sender can send two video streams to the receiver: the first is the main video of the meeting scene collected by the camera, and the second is Office documents such as WORD / PPT on the screen of a personal computer / notebook, or audio / video on devices such as DVD. Among them, the form of the first m...

Abstract

The invention discloses a high-definition dual-stream video transmission method, and the method comprises the following steps: a transmitting end transmits a first path of video and a second path of video with a first preset code rate to a receiving end of a video conference terminal device; when current bandwidth information and network transmission information fed back by the receiving end are received, if a video source type of the second path of video is static video, the transmitting end codes the rest of video picture frames with a second preset code rate when the current bandwidth information and the network transmission information satisfy a preset condition; and the transmitting end packages the coded video data and sends the packaged video data to the receiving end. The inventionalso discloses the transmitting end and the receiving end of the video conference terminal device, and a transmission system. With the method, the transmitting end, the receiving end and the transmission system provided by the invention, a problem of unsmooth playing of a high-definition dual-stream video can be solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a transmission method, a sending end, a receiving end and a transmission system of high-definition dual-stream video. Background technique [0002] Dual-stream technology is an advanced technology specially developed for the requirements of data applications in video conferencing. It realizes the synchronous transmission of video, audio and data through a call bandwidth, allowing participants to watch the speaker's graphics and hear the speaker's voice at the same time View active graphics from the speaker's computer; also display graphic information in high-definition resolution. Dual-stream video conferencing is to send two video streams to the opposite end during a meeting: one of which is the main video of the meeting scene collected by the camera, and the other is the personal computer / notebook screen or office documents such as WORD / PPT on it, or DVD audio / video on ...
