Abstract

The invention relates to a video data synchronous transmission method, apparatus and system. The method includes the following steps that: video data captured by a plurality of cameras arranged at different positions are acquired; frame images in the plurality of paths of video data are integrated into a frame image queue according to the sequence of the time axes of the frame images in the video data, so that frame images in the video data, which are contained in time periods of a preset length, are consistent quantitatively; and the frame images are sent out according to the sequence of the frame image queue. According to the video data synchronous transmission method, apparatus and system provided by the embodiments of the invention, the plurality of paths of video data are integrated into one path of video data, in a transmission process, the frame images in the video data, which are contained in the time periods of the preset length, are consistent quantitatively, and therefore, it can be ensured that data in all the video data can be sent to a display terminal with the same speed so as to be displayed, and it can be also ensured that the plurality of paths of videos can be displayed synchronously or with tiny time difference, and therefore, the synchronous consistency of spliced videos can be ensured.

Description

technical field [0001] The present invention relates to the technical field of computer applications, in particular to a video data synchronous transmission method, device and system. 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 The videos captured by the two camera devices need to be displayed on the same screen synchronously. [0003] In order to enable the videos captured by at least two cameras to be displayed synchronously on the same screen, the video data must be transmitted to the display terminal synchronously or with a slight time difference. The general implementation method is to transmit two channels of data separately. However, this method obviously cannot meet the requirement of synchronization. [0004] The...
