Abstract

The invention belongs to the technical field of video processing, and relates to a method and system for synchronously recording and replaying an original signal source based on a large screen window. The problem; the method includes: when recording, the recording and broadcasting service module queries the window layout and original signal source information of the large screen that needs to be recorded, initializes the user behavior sequence based on this information, and persists it; the scheduling service module selects the recording and broadcasting node that needs to participate; if If there is an available recording and broadcasting node, start the recording and broadcasting node service module to start recording, generate index files and video files; append video streams to video files, slice video files and update index files; when playback is required, schedule the service module to stream related The data restores the window layout according to the user behavior sequence, the RX module pulls the stream, and each node streams synchronously to complete the playback; through the present invention, signal source recording and flexible playback viewing can be realized.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a method and system for synchronous recording and playback of an original signal source based on a large screen window. Background technique [0002] In the existing splicing large-screen recording system, multiple video signals are combined into one and saved. Therefore, video stream encoding and decoding is required, which requires high equipment performance; when the spliced ​​video images are played back on the screen, they cannot be rearranged according to user needs, but can only be played back on the screen according to the layout during recording; the spliced ​​video images It can only be previewed globally. When you need to pay attention to the global preview and view some of the videos, the original solution can only start multiple recordings, which further improves the performance requirements of the device. Contents of the invention [0003] In...
