Problems solved by technology

[0003] The problem with this method is that the streaming media server needs to be redirected twice, and the redirection efficiency is relatively low. At the same time, the central server needs to receive VOD requests from multiple users in parallel, so its load pressure is relatively high.

Embodiment Construction

[0025] The technical solution of the present invention will be described in more detail below with reference to the drawings and embodiments.

[0026] As shown in Figure 1, realize the system that video-on-demand requests redirection in the IPTV system, comprise central server, one or more streaming media servers, user terminal equipment and one or more redirection servers;

[0027] The central server is used to compress and synchronize the distribution information of the media content on all the streaming media servers at the edge of the network to the redirection server at the same edge of the network as the streaming media server;

[0028] After the redirection server decompresses the distribution information of the received media content, it stores it in its own cache in the form of a memory database; The device returns the address information of the available streaming media server;

[0029] The user terminal device is used to send a media service redirection request to ...

Abstract

The present inventionrelates to a system for requesting the redirection of vide-frequency order-program VOD in the IPTV system. The system includes a center server, a media server, and a user terminal device as well as one or a plurality of redirection servers. The VOD is redirected through the following steps: the redirection server receives and keeps the content information distributed by the center server to the media server synchronous with and positioned at the same network edge as the redirection server; and then the user terminal device sends the request for redirecting the media serve to the redirection server, and the latter returns the address information of the media server available to the user terminal device; and the user terminal device sends the request of media serve to the media server according to the received information; after the media server receives the address, the media serve begins. By adopting the present invention, not only can the redirection request of the VOD order-program be realized apace, but also the pressure of the center server can be reduced, thus making the requests of the users replied as soon as possible.

Description

technical field [0001] The invention relates to the field of IPTV (Internet Television) multimedia services, in particular to a system and method for realizing video on demand (VOD) request redirection in an IPTV system. Background technique [0002] The improvement of network bandwidth and the development of network technology provide the possibility to carry out multimedia value-added services on the existing network. Streaming media technology provides a way to transmit media content such as video, audio, and pictures in the network, so it has been widely used in multimedia service systems, especially IPTV multimedia services. At present, in the IPTV multimedia service system based on streaming media technology, VOD media content on demand usually adopts the following method: a data center is set up in the network center to store the distribution information of all VOD media content in the system, and each network edge node sets One edge server and multiple streaming ser...
