Abstract
This invention relates to an EPG method for digital TV increment services including: a processor of the transmission end generates expanding EPG data to generate a transmission flow with the EPG data and program content to be played, the user terminal receives the transmission flow to analyze the EPG data and display the information and parameter contained in the data and provide them to users.
Description
Technical field
The present invention relates to radio data system EPG, particularly the extended method of Digital Television EPG.
Background technology
EPG is the abbreviation of English Electrnic Program Guide (electronic program guides).This guide is a data structure that is applied in the radio data system, and it has described the information of all programs that offer the televiewer, is the important technology that constitutes interactive television.The EPG that uses in traditional Digital Television only comprises a small amount of video program information, and broadcasts to terminal with the programme signal data when broadcasting.After using Digital Television value-added service platform, original EPG information can't satisfy instructions for use.At first the business tine that provides of value-added service platform is abundanter than traditional, and secondly value-added service platform more is the IP data, and how allowing EPG and IP data transmit together becomes a problem.
Summary of the invention
The object of the present invention is to provide a kind of extension EPG method that increases the Digital Television value-added service of data volume.
Purpose of the present invention can realize like this, designs a kind of extension EPG method of Digital Television value-added service, may further comprise the steps:
A, transmitting terminal processor generate the expansion EPG data respectively according to the COS that Digital Television value-added service platform provides;
B, transmitting terminal processor generate transport stream with the expansion EPG data with want broadcast program content;
C, user terminal receive transport stream, and terminal handler is resolved the expansion EPG data;
Information that D, user terminal displays expansion EPG data comprise and parameter are selected for the user.
The present invention has abundant content and more powerful function flexibly more.
Description of drawings
Fig. 1 is the schematic diagram of preferred embodiment of the present invention.
Embodiment
The invention will be further described below in conjunction with embodiment.
As shown in Figure 1, the extension EPG method of Digital Television value-added service may further comprise the steps:
A, transmitting terminal processor generate the expansion EPG data respectively according to the COS that Digital Television value-added service platform provides;
B, transmitting terminal processor generate transport stream with the expansion EPG data with want broadcast program content;
C, user terminal receive transport stream, and terminal handler is resolved the expansion EPG data;
Information that D, user terminal displays expansion EPG data comprise and parameter are selected for the user.
The present invention is based on the Digital Television value-added service platform.
The data of expansion EPG described in the step are to generate, transmit, receive, resolve with the form of file.Expansion EPG is to generate, transmit, receive, resolve with the form of file, and different classs of service identifies and transmits with different expansion EPG files.
The service that the value-added service of Digital Television described in step platform provides comprises digital TV video frequency service, data download service.The service that Digital Television value-added service platform is provided can also provide other service of data download service and value-added service platform except that traditional digital TV video frequency service.
Described Video service expansion EPG file comprises programm name, Pgmtime, programme content explanation, sends the information data of frequency, PID, bandwidth.
At the terminal of supporting instant message, the information data that described Video service expansion EPG file also comprises number of times, the interlude of broadcast and is presented at the position on the picture when playing.
At the video frequency program that will broadcast, programm name that the present invention is can layout detailed and Pgmtime and programme content explanation also need to set number of times, the interlude of broadcast and are presented at position on the picture when playing at the terminal of supporting instant message.Generate the program guide (EPG) file in conjunction with the corresponding transmission information such as frequency, PID, bandwidth that send then, this EPG file is write with the prescribed form standard, generate the transport stream that meets the digital television transfer standard with the programme content that will play, sending platform by Digital Television sends, the user can receive expansion EPG information with terminal, watches the digital TV video frequency program according to what the information that expansion EPG provided was allowed a choice.
Described data download service expansion EPG file comprises title, the download time of downloaded resources, the information data and the transmission information data that sends frequency, PID, bandwidth of download content introduction.
The download function that provides at digital television system, the present invention can generate the expansion EPG file with transmission information with information such as the title of downloaded resources, download time, download content introductions, be made into the download message transport stream that meets the digital television transfer standard equally, send platform by Digital Television and broadcast.End product is by resolving the expansion EPG file, and acquisition can just can be enjoyed the service that provides for the tabulation of downloaded resources.
For example, Digital Television value-added service platform provides 5 cover video frequency program and 10 downloaded resources.Platform generates expansion EPG automatically and issues.The expansion EPG file that generates is called after shipin and xiazai respectively.After the terminal use receives expansion EPG, resolve the shipin file, therefrom obtain the information of the 5 cover video frequency programs that front end broadcasts and receive parameter, and be shown to the user and select by terminal equipment; Resolve the xiazai file, therefrom obtain the information of 10 downloaded resources that front end broadcasts and download parameter, and be shown to the user and select.
The ISDB-T standard of the ATSC standard of the terrestrial DTV standard that the transmission standard that Digital Television value-added service platform adopts is formulated including but not limited to China, European digital television standard (DVB-S/T/C), the U.S. and Japan.
The business tine that described expansion EPG comprises has other service of digital TV video frequency service, data download service, value-added service platform.Needed call parameter of above-mentioned service and information all are embodied in the expansion EPG.The content of described expansion EPG includes but not limited to that programme channel tabulation, program introduction, program are arranged constantly, program receives parameter, data are downloaded contents list, data are downloaded content introduction etc.
When the digital TV terminal product parses the EPG information flow that receives, just can watch program or data download according to its programme information that comprises.
