Abstract

The invention discloses a method for redirecting a multimedia content on demand request in an internet protocol television (IPTV) system. The IPTV system adopts a tree structure with a plurality of nodes, wherein each node is provided with a plurality of access points (APs) and a plurality of streaming media servers; each AP is relevant to multimedia content types; and each multimedia content type corresponds to different content direction strategies. The method comprises the following steps: receiving a multimedia content on demand request from a user at one AP; according to the AP number, determining the multimedia content type related to the multimedia content on demand request; and according to the content direction strategy corresponding to the determined multimedia content type, redirecting the multimedia content on demand request to a proper streaming media server. In addition, the invention also discloses corresponding redirection equipment for redirecting the multimedia content on demand request.

Description

technical field [0001] The present invention relates to an interactive network television (IPTV) system, in particular, relates to a technology for redirecting a multimedia content on-demand request from a user in the IPTV system. Background technique [0002] Currently, the IPTV system has been widely used commercially. IPTV is a multimedia communication technology based on the Internet. It uses the infrastructure of broadband network and uses home TV or personal computer as the display terminal to provide TV channel programs and other multimedia content to end users. The main features of IPTV are interactivity and real-time. [0003] Conventional IPTV systems usually use a centralized control agent (eg, IPTV control center) to enforce different policies for different services or content types based on user's requests. Generally, the content delivery network of the existing IPTV system includes a centralized control center and multiple edge servers. Usually, when a user'...
