Problems solved by technology

[0004] Traditional multimedia file recording methods are generally based on hardware acquisition boards, using video and audio cables to connect video and audio signal output to the board, and then the board realizes data reception and file generation, the format of the received file signal and the output format. The generated file format has certain restrictions, and the number of simultaneous parallel recordings is also limited by the number of hardware versions, so the scalability and flexibility are poor

Abstract

The invention provides a multi-data-rate network recording method and device. The method comprises the following steps: obtaining network flow data collected by an internet-of-scene server, wherein the network flow data is a binary code based on an internet-of-scene protocol; analyzing the network flow data according to an internet-of-scene coding and decoding protocol, and extracting video data and audio data from the network flow data; synthesizing the video data and the audio data to obtain a plurality of multimedia files corresponding to different specific data rate and / or specific formats; and sending the plurality of multimedia files to the internet-of-scene server. The multi-data-rate network recording method and device have higher compatibility for formats of the received video and audio data, thereby greatly improving dynamic scalability of parallel recording number, and meeting use of video resources at different scenes; and the method and device have high flexibility.

Description

technical field [0001] The invention relates to the technical field of video networking, in particular to a multi-stream network recording method and a multi-stream network recording device. Background technique [0002] The Internet of Vision is an important milestone in the development of the network. It is a real-time network that can realize real-time transmission of high-definition video, and push many Internet applications to high-definition video, high-definition face-to-face.
