Method and system for redundant hot backup of streaming media live recording

Abstract

The invention discloses a redundant hot backup method for streaming media live recording, which includes: synchronously inputting coded streams encoded by live encoders to the main and backup networks; publishing live channels and configuring input source information through a background management system; streaming media The controller adopts the main-standby hot-standby mechanism to control the recording task controller to start or stop the live recording task through the API interface; when the recording task controller starts the live recording task, it will record and distribute the code stream of the connected live encoder The system stores and sends heartbeat message information to the streaming media controller at regular intervals; the streaming media controller monitors the status of all live recording tasks and performs distributed storage of the status data of the live recording tasks. The invention also provides a redundant hot backup system for streaming media live recording. Implementing the technical solution provided by the invention can realize fast redundant hot backup, improve efficiency and reduce cost.

Description

technical field [0001] The invention relates to the technical field of streaming media processing, in particular to a method and system for redundant hot backup of streaming media live recording and recording. Background technique [0002] With the vigorous development of Internet live broadcasting, more and more live broadcasting platforms have emerged, such as Internet TV, Internet radio, etc. Users can use the playback terminal provided by the live broadcasting platform to conveniently play remote live broadcasts in real time without going to the scene. Live content, such as events, conferences, teaching, surgery, etc. Whether it is due to the requirements of supervision and content review, or to directly support time-shifting and playback in the later stage, the demand for live recording has become more and more extensive. [0003] However, the current live broadcast platform has not yet provided an effective live recording redundant hot backup technology solution. The...

Problems solved by technology

The main reason is that due to the limited bandwidth and storage capacity of the central server itself, it is easy to become the bottleneck of the entire network service when serving thousands of users, especially when a large number of user requests are flooded in instantly.

The most common existing streaming media transmission technology is to use a separate server to record several channels fixedly, and because it does not support redundant hot backup, when one of the recording and broadcasting servers fails or goes down, the entire business will be affected. Interruption, and manual switching to another cold backup recording and broadcasting server is required. The business interruption time is long, which greatly affects the data transmission efficiency and end-user experience

[0004] And the existing live recording backup method usually adopts the way of dual-machine hot standby, that is, the backup device will record the same copy of the streaming media data as the main device, resulting in a large amount of redundant storage, wasting limited storage resources and resources. Storage I / O (input / output) access bandwidth will also significantly reduce the read and write performance of the entire system and the number of concurrent services; in addition, additional disk read and write operations will also damage the disk life, which in turn will reduce the server's MTBF (mean failure) Interval time), which also indirectly increases the hardware cost of the entire system
