Embodiment Construction

[0047] In order to reduce the burden on the EPG server and the client's ability requirements when switching VOD services, the embodiment of the present invention provides a method for implementing VOD services. The EFG server provides the IP address information of the scheduling server to the user client device, and the user According to the acquired IP address information of the scheduling server, the client device requests the IP address information of the streaming media server from the scheduling server, and then establishes an RTSP session with the available streaming media server for VOD services.

[0048] The embodiment of the present invention also provides two failover mechanisms to ensure that when the streaming media server providing VOD services fails, the client device can be switched to the normal streaming media server to continue VOD services, wherein:

[0049] In the first failover mechanism, when the streaming media server that provides VOD services fails, the...

Abstract

A method for realizing video on-demand service includes providing URI with IP address of dispatch server to client end device by EFG server, requesting stream media service from dispatch server by client end according to obtained URI and redirecting onto available stream media server for carrying out VOD service, re-requesting IP address of available stream media server from dispatch server by client if stream media server being used on VOD service is failure then redirecting onto another stream media server to carry out VOD service continuously.

Description

technical field [0001] The invention relates to streaming media services, in particular to a technology for realizing video-on-demand services. Background technique [0002] The development of traditional analog TV to digital TV has laid a foundation for the flexible processing of TV programs, and various novel services have emerged one after another. The characteristics of the initial broadcast TV service are one-way (the user has no service interaction with the head end) and broadcast type (many users watch the same program). Subsequently, according to the needs of users, a video on demand (VOD) service appeared. The operator prepared a large number of movies in advance and stored them in the video on demand system. On-demand request, freely control the fast forward and rewind of the program, no longer passive and one-way viewing. [0003] After broadcasting and TV are missed, it is difficult to see them again, while video on demand occupies a high cost of servers and ne...
