Problems solved by technology

[0005] However, in practical applications, this push mechanism has a defect: if the server pushes multiple fragments to the client prematurely, it will cause a large waste of bandwidth when the user suddenly stops watching; if the server pushes multiple fragments If it is too late, the client cache may be insufficient and the playback may freeze

Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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.

[0030] figure 2 A schematic diagram of a media resource push system 200 provided by an embodiment of the present invention includes: a server 201 , a client 202 and a network 203 . The client 202 communicates with the server 201 through the network 203 .

[0031] Wherein, the client is responsible for sending a segment request message to the server for requesting the server to obtain segments, where the segments include initialization segments and media segments. The initialization segment includes metadata required for media resource playback, and the media segment includes real data of the media resource. The fragment request message may include a push instr...

Abstract

The invention provides a media resource push method, client side and server. According to the method, the server receives a fragmentation request message carrying a push instruction transmitted by theclient side, wherein the push instruction includes a fragmentation push identifier and push strategy indication information; the server determines fragmentation push time corresponding to the fragmentation push identifier according to the push strategy indication information; and the fragment corresponding to the fragmentation push identifier is pushed to the client side according to the push time. The push strategy indication information is added in the push instruction transmitted to the server by the client side and the server can perform fragment pushing according to the push strategy indication information so that smooth playing of the client side can be guaranteed and waste of bandwidth caused by stopping watching of the user can also be prevented.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method for pushing media resources, a client and a server. Background technique [0002] There are many ways for the user terminal to obtain media resources and play them. Typical ones are: HTTP (HypertextTransfer Protocol, Hypertext Transfer Protocol) file download or P2P (Peer to Peer, peer-to-peer) file download to the local disk and play, HTTP progressive Download (HTTP Progressive Download) and HTTP dynamic adaptive streaming (Dynamic Adaptive Streaming over HTTP, DASH) scheme and so on. Among them, DASH puts forward a series of technical requirements on various aspects involved in the transmission of Moving Picture Experts Group (MPEG) media through HTTP. [0003] Specifically, the DASH standard regulates the format of a media description file (Media Presentation description, MPD) and a segment (Segment). Any media resource is composed of fragments. A fragm...
