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

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] The invention provides a method for synchronous live broadcast of multiple groups of cameras.

[0035] Install several digital high-definition cameras on the sports field according to different angles and areas;

[0036] Simultaneously broadcast the same game through several digital high-definition cameras;

[0037] When collecting several digital high-definition camera videos, the current time stamp is automatically added to ensure time synchronization of multiple videos;

[0038] 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.

[0039] 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 of multiple groups of cameras. A plurality of digital high-definition cameras are installed at a sports field according to different angles and regions; simultaneous live broadcast of the same match is realized through the plurality of digital high-definition cameras; during acquisition of videos of the plurality of digital high-definition cameras, current timestamps are automatically added; and a directed broadcasting tool receives multichannel video information, automatically adjusts the size of a buffer region according to thetimestamps, and selects an appropriate time-delay duration to play the videos. The playing times of multichannel videos can maintain synchronous, and the smoothness of video playing and the consistence of images are improved.

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...
