Problems solved by technology

However, the problem that exists in reality is to take a basketball game as an example. There will be multiple sets of cameras distributed in multiple angles and areas on the court, and the videos captured by these cameras will be displayed at inconsistent times due to network conditions, which will lead to poor terminal perception. , screen inconsistency problem

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] The invention provides a method for synchronous live broadcast of multiple groups of cameras.

[0027] Install several digital high-definition cameras on the sports field according to different angles and areas;

[0028] Simultaneously broadcast the same game through several digital high-definition cameras;

[0029] When collecting several digital high-definition camera videos, the current time stamp is automatically added to ensure time synchronization of multiple videos;

[0030] After receiving multi-channel video information, the broadcast guide tool automatically adjusts the buffer duration according to the timestamp, and selects an appropriate delay time to play, so that the multi-channel video playback time is kept in sync.

[0031] The broadcasting tool decodes the respectively received video data to obtain the time stamp of the video d...

Abstract

The invention discloses a method for synchronous live broadcast through multiple cameras. A plurality of digital high definition cameras are installed in the sports field according to different angles and regions; the plurality of digital high definition cameras perform live broadcast of the same game simultaneously; when the videos of the plurality of digital high definition cameras are gathered, a current timestamp is automatically added; after a director tool receives multi-channel video information, the size of a buffer zone is adjusted automatically according to the timestamp, and a proper delay duration is selected for playing the video. The multi-channel videos are played synchronously, so that video play smoothness is improved, and the frame consistency is guaranteed.

Description

technical field [0001] The invention relates to a live broadcast method, in particular to a method for synchronous live broadcast by multiple groups of cameras. Background technique [0002] With the development of live broadcast network technology, users can watch sports games online through the network, such as watching basketball games, need to collect on-site image data, that is, transmit video data to other users, and play the collected video on other users data. [0003] The traditional way of video acquisition and transmission is to use a single channel to transmit the merged video, and play the merged video at the receiving end. However, the problem that exists in reality is to take a basketball game as an example. There will be multiple sets of cameras distributed in multiple angles and areas on the court, and the videos captured by these cameras will be displayed at inconsistent times due to network conditions, which will lead to poor terminal perception. , the p...
