Embodiment Construction

[0017] The implementation of the present invention will be specifically described below in conjunction with the drawings. like image 3 As shown, the main steps to realize the data synchronization method of the digital TV charging service system are as follows:

[0018] 1. Start the service management background and monitor the query interface;

[0019] 2. The set-top box background sends a query request to the service management background through the http protocol;

[0020] 3. The service management background responds to the request, accesses the service management background database according to the request parameters, and returns the response information in the form of an xml file;

[0021] 4. The set-top box background parses the xml file in the xml parsing module;

[0022] 5. The background of the set-top box uses the database update module to update the local database according to the content of the xml file.

[0023] First, a set of interfaces are predefined in t...

Abstract

The invention discloses a method for synchronization of service provider background data and set-top box background data in a charging service system of a digital television. The digital television service management system presets a group of interfaces, a background program of a set-top box accesses the group of interfaces so as to query the database of the service management system, the service management system returns an XML file and stores relevant information, and the set-top box background uses a DOM parser for parsing the returned XML file and updates data of the local database according to the information, thus ensuring synchronization of data on the two servers. As certain static data of the service management system is stored in the background server of the set-top box, communications between the service management system and the background server of the set-top box can be reduced to a great extent, unnecessary data transmission is avoided, thereby increasing the response speed of digital televisions.

Description

technical field [0001] The invention relates to the application field of set-top boxes, in particular to a data synchronization method of a digital TV charging service system. Background technique [0002] As a new TV form and media, digital TV has begun to enter millions of households. The important feature of digital TV is that the content is rich and colorful. In addition to basic digital TV broadcast programs, there are also on-demand programs, various information browsing columns, and so on. In the previous TV service mode, people mainly received TV programs passively, and TV users could only watch whatever programs were broadcast by TV stations. Although the TV industry has made great progress this year, people can receive more and more TV programs, but this has not fundamentally changed the passive relationship of people watching TV. If a user likes a certain program, he can only watch it at a certain fixed time, which greatly weakens people's enthusiasm and enthusi...
