Embodiment Construction

[0053] The invention discloses a structure-independent EPG access method. The EPG access method enables the search server to be independent of the format of the EPG. The EPG can enter the search server in any format, and the search server provides the index to the client for searching.

[0054] Through the EPG access method of the present invention, XML files in any format can be stored and retrieved, and the search server processes the input EPG XML files to generate its structural information, and the terminal user has an XPath-like character string when searching , are the search path and the granular path of returned results, respectively, so that the search server can understand the format that the end user wants to search for and the format it expects to return.

[0055] Such as figure 1 The above is a schematic flow chart of an EPG access method according to an embodiment of the present invention, and the method mainly includes:

[0056] Step 11, the XML file of the E...

Abstract

The invention discloses an EPG access storage method and a system thereof. The method comprises the steps of making an XML file of the EPG enter a search server, traversing the XML file by the search server and storing the structural information thereof; obtaining a search result, wherein the parameters are respectively the format of a search target and a granularity expected to return; and searching and constructing a returned result by an EPG search server according to the parameter set by the URL of a user. By the invention, the EPG search server does not need to know the structure of the EPG and the server does not need to change when the EPG structure is changed. The invention reduces the retransmission and development of program developers.

Description

technical field [0001] The invention relates to digital television technology, in particular to an EPG access storage method and system. Background technique [0002] Electronic Program Guide (EPG, Electronic Program Guide) provides a simple and convenient operation platform for the use of basic services (such as VOD / BTV / songs) and various value-added services provided by Internet Protocol Television (IPTV, Internet Protocol Television). It provides a good navigation mechanism for users to watch TV programs, enjoy multimedia program on demand and carry out information services. EPG has become an important symbol of digital TV, and is the gateway for viewers to enter digital TV and IPTV. [0003] The indexing and navigation of various services provided by IPTV are completed through the EPG system. IPTV EPG is actually a portal system of IPTV. The interface of the EPG system is similar to that of a Web page. The EPG interface generally provides various menus, buttons, links...
