Abstract
The invention relates to an EPG (Electronic Program Guide) server of an IPTV (Internet Protocol Television), which comprises a data-importing interface, an EPG editing module, a multiplexing interface and an electronic-program template base, wherein the data-importing interface is used for importing related program data; the EPG editing module is used for editing the related program data imported by the data-importing interface; the multiplexing interface is used for multiplexing the data edited by the EPG editing module into a TS (Transport stream) for transportation through a network; and the electronic-program template base is used for storing a plurality of electronic-program templates corresponding to the attributes of users and is convenient for selecting the electronic-program template displayed on a screen by a user terminal. Through the EPG server of the IPTV, the related program information of various program signal sources can be edited into EPG information, and different electronic-program guide templates are set according to the different-type users of the user terminal; and meanwhile, advertising content in the electronic-program templates is flexibly set, so that many kinds of program signal sources are compatible, and the usage experience of different users is enriched.
Description
Technical field
The present invention relates to a kind of network TV IPTV field, relate in particular to the electronic program guide (EPG) server of a kind of IPTV.
Background technology
EPG is the english abbreviation of Electronic Program Guide, and the meaning is electric program menu.The index of the miscellaneous service that IPTV provides and navigation are all finished by the EPG system.In fact IPTV EPG is exactly the gate system of IPTV.The interface of EPG system and Web classes of pages are seemingly, the assembly of directly clicking when generally all providing all kinds of menus, button, link etc. to supply the user selection program on the EPG interface also can comprise the dynamic or static content of multimedia that all kinds of users of confession browse on the interface of EPG.
But, China IPTV also is in the starting stage at present, part TV station, operator and set-top box production firm had once developed some EPG servers, but all be the EPG server for some networks or a kind of set-top box, lack widely applicability, the problem of several aspects below existing in actual applications: on the one hand, the EPG content information lacks unified data format, give each, exchange EPG brings very large complexity between the net, the necessary design and development EPG server of each digital TV platform causes a large amount of repeated labors; Poor compatibility, set-top box manufacturer has to for each platform overlapping development EPG server; On the other hand, existing EPG server can not be for the user type flexible choice EPG indicating template of user terminal such as IPTV STB, can not automatically switch at the ad content of the special column administration page of the EPG of user terminal indicating template according to the time.
Therefore, need a kind of highly compatible, intelligentized IPTV EPG server, can satisfy the demand of the programme information access of various program manufacturers such as TV station, can adjust EPG display interface style according to user type again, can also be according to advertiser's demand of operator, ad content on the automatic switchover EPG indicating template is to make things convenient for simultaneously program manufacturer, IPTV operator and user.
Summary of the invention
In order to address the above problem, the invention provides a kind of EPG request of user terminal such as IPTV set-top box STB and self adaptation is selected the IPTV of EPG template according to user type EPG server of receiving, so that described EPG server has the compatibility interface that receives the various kinds of programs information source, make the EPG content with the pertinent program information that receives the various kinds of programs information source, change the EPG indicating template according to the user type self adaptation of request EPG simultaneously, and switch in time advertising message on the EPG template, thereby improved the intelligent degree of EPG server.
According to an aspect of the present invention, provide the EPG server of a kind of IPTV, comprised the data importing interface, imported the program related data; The EPG editor module is edited the program related data that described data importing interface imports; Multiplex interface transmits the data-reusing behind the EPG editor module editor in transport stream TS stream by network; The electronic program list ATL has been stored a plurality of electronic program list templates corresponding with user property, is convenient to user terminal the electronic program list template that is presented on the screen is selected.
