Method and system for synchronously recording and playing back original signal source based on large screen window

Abstract

The invention belongs to the technical field of video processing, relates to a method and a system for synchronously recording and playing back an original signal source based on a large screen window, and aims to solve the problem that any video signal cannot be flexibly called and checked during recording and playing back of an existing large screen window. The method comprises the following steps: during recording, a recording and broadcasting service module queries a window layout of a large screen needing to be recorded and original signal source information, initializes a user behavior sequence based on the information, and persists the user behavior sequence; a scheduling service module selects recording and broadcasting nodes needing to participate; if available recording and broadcasting nodes exist, a recording and broadcasting node service module is started to start recording, and an index file and a video file are generated; a video stream is added to the video file, the video file is spliced and the index file is updated; when playback is needed, the scheduling service module fluidizes related data, restores a window layout according to the user behavior sequence, pulls streams by an RX module, and synchronously fluidizes each node to complete playback. According to the 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.
