Abstract

The embodiment of the invention provides a monitoring and video conference application integration platform and method, and relates to the visual command technology. The problems that audio and video synchronization and effective fusion of video conference and video monitoring cannot be realized at present are solved. The method comprises the following steps: obtaining a to-be-played audio timestamp in an audio buffer area, and recording the to-be-played audio timestamp as A; figuring out a video timestamp correspondingly synchronized with the audio, and marking the video timestamp as B; obtaining a to-be-played current video timestamp from a video buffer area, and recording the to-be-played current video timestamp as V; calculating S, wherein the S=l V-B l / ClockB; if S is not greater than 100ms, playing the current video; if S is greater than 100ms, and V is smaller than B, discarding the video packet; and if S is greater than 100ms, and V is greater than B, repeatedly displaying the same frame. The monitoring and video conference application integration platform and method is mainly applied to audio and video synchronization.

Description

Technical field [0001] The invention relates to the technical field of visual command integration, in particular to a monitoring and video conference application integration platform and method. Background technique [0002] The traditional monitoring center and the video conference venue are independent of each other, causing the integration problem of the monitoring system and the video conference system. When emergencies occur, such as traffic accidents, fires, floods, etc., if you want to understand the on-site environment in real time, you can only Central observation, and it is impossible to realize the video conference discussion with live real-time images and live audio as materials. At the same time, audio and video are transmitted as independent data streams on the network, and currently cannot be synchronized, which brings extremely poor experience to users. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the pri...
