Problems solved by technology

[0003] However, the HLS technology itself has the problem of large live broadcast delay, because the output of the HLS encoder is in units of fragments, so the live broadcast delay is at least 1 fragment, which is very poor for the user's live broadcast experience, and the HLS live broadcast unicast method is also limited The Internet Protocol (Internet Protocol, IP) video service has developed on a large scale; currently, with the digital video conversion box (Set TopBox, STB) technology becoming more and more mature, the industry generally adopts the following playback mechanism:
[0004] HLS unicast live broadcast + HLS time-shifted playback, this method can realize live broadcast / time-shifted playback services, but the delay of live broadcast is large, and the HLS live broadcast unicast method has requirements for concurrent service volume and backbone network bandwidth, which also limits IP video Large-scale business development

Embodiment Construction

[0061] The media file playback method provided by the present invention is applied in a media file playback system. The system is composed of a server and a client. Through the integration of multicast live broadcast and HLS time shift, the multicast transport stream (Transport Stream, TS ) The code stream is provided to the client's multicast live broadcast service through the multicast service, and the HLS fragments are recorded and provided to the client's time shift service.

[0062] Specifically, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0063] figure 1 It is a flowchart of Embodiment 1 of a method for playing media files of the present invention, such as figure 1 As shown, the method for playing media files provided by the present invention is applied to the server. The server can exist alone or in a content delivery network (...

Abstract

The embodiment of the invention discloses a media file playing method. The method comprises the following steps: performing encoding processing on a media file to obtain a multicast transport stream TS code stream and dynamic code rate adaptive HLS fragments; and providing multicast live broadcast service according to the multicast TS code stream, and providing time shift service according to the HLS fragments. The embodiment of the invention further discloses a server, a client and a media file playing system.

Description

Technical field [0001] The invention relates to the technical field of multimedia terminal audio and video playback, in particular to a media file playback method, server, client and system. Background technique [0002] With the rapid development of the mobile Internet, the promotion of Over The Top (OTT) technology and the emergence of various smart terminal devices, it has become more and more common for people to watch videos online through video terminals such as mobile phones, handheld computers, and set-top boxes. Leisure and entertainment; the dynamic bit rate adaptive (HTTP Live Streaming, HLS) protocol proposed by Apple is currently a relatively mature OTT technical specification. The video source can be encoded into multiple bit rates, and various bit rate video sources can be cut into several A segment of about 10 seconds. The segments with the same serial number in different bit rates correspond to the same video content. At the same time, the m3u8 index file is gene...
