Realization method for cable interactive television cross-domain video service connection system

Abstract

The invention relates to a realization method for a cable interactive television cross-domain video service connection system. The method comprises the following steps: defining video-on-demand request data in an XMPP (Extensible Messaging and Presence Protocol) message format by a digital television set-top box; when an interactive television cross-domain video service is used by a user, bearing a video-on-demand request and a supportable media format through an XMPP message, sending out a service connection request, automatically forming a friend relationship in an XMPP message channel together with a video service system connected with an operator domain, and after the video service system connected with the operator domain receives the XMPP message of the user video-on-demand request, analyzing and processing the XMPP message, distributing video service resources for the digital television set-top box and pushing video programs to the digital television set-top box initiating the request in a media format compatible in the request. Therefore, the problem of video-on-demand protocol compatibility between different digital television set-top boxes and different video service systems connected with operator domains is solved, and the trouble that the set-top box needs to be updated once when being connected with a new operator domain is avoided.

Description

technical field [0001] The invention relates to a cable interactive TV docking technology, in particular to a method for realizing a cable interactive TV cross-domain video service docking system based on the XMPP protocol. Background technique [0002] Generally speaking, the interactive TV provided by the cable network uses a digital TV set-top box as a terminal, while Internet video and applications use mobile smart terminals such as smart phones and tablet computers. For multi-screen sharing, the XMPP protocol is generally used as the basic protocol for message communication, so that services developed by the same operator can be interconnected within its network. We call such an interactive TV service and bearer network an operator domain. [0003] At present, domestic cable networks are basically operated on the basis of provincial administrative regions. For example, Beijing operators only manage the local cable network in Beijing, and Shanghai operators only manage ...

AI Technical Summary

Problems solved by technology

The problem with this method is that the digital TV set-top box is a relatively low-cost terminal device, and its processing capacity and storage space are limited. The more protocols, the more prone to various failures

Moreover, every time a docking with a new operator domain is performed, the software code of the set-top box needs to be upgraded, which puts a lot of pressure on the operation of the cable network operator.
