Abstract

The invention discloses a caching and playing method and system of live playback, and belongs to the technical field of the streaming media. The method comprises the following steps: downloading a TSmedia slice file through a channel source station; storing the TS media slice file in a memory; storing the TS media slice file stored in the memory in a distributed file system at the fixed time according to the preset time period, and deleting the corresponding TS media slice file in the memory. The TS media slice file downloaded through the channel source station is stored in the memory, and the TS media slice file stored in the memory is stored in a distributed file system at the fixed time according to the preset time period, the problem that the storage is performed only depending on theDFS in the prior art is overcome, the classified cache mechanism is realized in the premise of not losing a lot of storage space and reducing the dependence on the DFS, the storage resource is saved,the dependence on the DFS is reduced, and the live security is improved.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a caching and playing method and system for live playback. Background technique [0002] The improvement of network bandwidth and the development of 3G / 4G wireless communication technology provide the possibility to carry out value-added service business based on media content on the telecommunication network. A CDN (Content Delivery Network, content distribution network) system is further widely used as a system for caching videos, audios, pictures and web pages in the network. The CDN system is also playing an increasingly important role in developing multimedia services in the telecommunication network, such as IPTV (Interactive Network Television) and OTT TV (Open Internet Video Service). [0003] In the current OTT TV, the more mainstream live channel services are based on HLS (HTTPLiveStreaming, Apple's dynamic bit rate adaptive technology), such as LTV (Live TV, l...
