This article introduces you how the live time-shift technology of OTT solution is. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

OTT refers to Internet companies beyond operators to develop a variety of video and data services based on the open Internet. More and more families prefer to buy small Android boxes instead of relying on TV cable signals.

In particular, it is convenient and affordable to watch live TV channels in a small box, and there is another advantage: even if a wonderful World Cup goal is delayed by a damned work phone, you can also go back to the previous 10 minutes and make up the missed live content in time. This kind of live content can also be watched in time for a certain period of time, which is called live time shift.

The principle of time shift in live broadcast

Live time shift is mainly used in emerging network TV stations. Through the coding and transcoding system, the ordinary video signal is output to a stream (such as FLV format), sliced and indexed, then packaged and distributed through the streaming media server system, and finally synchronously output to various terminals, such as TV, PC, pad, mobile phone. The live content seen by the end user can be watched in time without having to wait for the playback the next day.

Users can pause while watching live programs, and then continue to watch from the pause, so as not to miss some important plots. Technically, when pausing the request, the playback server records the program, and when it continues to play, the recorded program is replayed.

Live broadcast time shift advantage

Live broadcast time-shift technology is implemented in a unique and efficient way, with the combination of unlimited storage and real-time stream caching, which realizes the seamless integration of recording and live streaming. Users can choose any channel, code rate, and time point, watch any program at any time, and return to the broadcast point at any time.

At present, some systems have been able to achieve multi-screen and multi-system playback, supporting different terminal self-adaptation. For example, 800li media server can support the playback of web, ios, android systems, and support multi-stream and adaptive technology. According to the different playback terminals, the system will output the corresponding protocol stream at the same time to ensure that each terminal can play smoothly.

A solution that supports OTT solution for LVB time shift (take 800li media server as an example)

1. Cluster architecture that supports large concurrency

two。 Fully equipped user management system

3. Concise and clear time-shifting interface

4. P2P technology that saves a lot of bandwidth

a. Decentralized: distribute server-centric services to each module node to avoid server performance bottlenecks

b. Scalability: as more users join, the overall resources and services of the network have been enhanced and expanded

c. Robust stability: network self-organizing management, the problem of a node or local network in the network will not have a great impact on the whole network

d. Resource sharing: can effectively use the idle hardware resources in the network for computing and storage

e. Optimize propagation speed: data propagation is transmitted directly between nodes, so when user data increases, its data propagation speed will be greatly enhanced.

This is the end of the live broadcast time-shift technology of OTT solution. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
