Abstract

The present invention provides a video data transmission method and apparatus. The method includes the following steps that: video data captured by a plurality of cameras arranged at different positions are acquired; and video data captured by one of the cameras are adopted as first video data, and are transmitted to a display terminal in real time, and video data captured by the other cameras are stored; and when the photographing of the cameras is terminated, the other stored video data are sequentially transmitted to the display terminal, so that the display terminal can splice images at corresponding positions on the time axis of all the video data according to a preset format, so that a spliced video can be formed. According to the video data transmission method provided by the invention, in a transmission process, a plurality of paths of video data are transmitted separately, so that requirements for the bandwidth of a data transmission interface can be lowered.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a video data transmission method and device. Background technique [0002] People have more and more demand for video shooting, especially in more and more scenes, such as monitoring, follow-up shooting, scientific research observation, etc., it is necessary to shoot multiple scenes, or shoot from multiple angles for the same scene, and more Videos taken by two cameras need to be displayed on the same screen. [0003] In order to enable the videos captured by at least two cameras to be displayed on the same screen, the video data must be transmitted to the display terminal or with a slight time difference. A general approach is to increase the bandwidth of the data interface so that the data interface can simultaneously transmit at least two channels of video and data. However, for interfaces with a smaller bandwidth such as USB, it is obviously unable to ...
