CN102469364A - Interactive television system with bi-directional EPG interface - Google Patents

Abstract

The invention provides an interactive television system with a bi-directional EPG interface, which comprises nine days of EPG information. The program forecast information of 7 days beginning from the day and the watch-back program information of 3 days which are the day plus the past 2 days are integrated in one EPG interface. Users can watch the current programs through the interface, can view, notify and prerecord the program forecast information in 7 days, and can directly request the watch-back programs in 3 days, so the system is convenient for the watching experience of the users.

Description

The interactive television system at two-way EPG interface

Technical field

The present invention relates to the service field of interactive TV, particularly interactive TV playback, the field of pre-recording.

Background technology

Interactive TV is different from traditional TV programme to be play, and no longer is such in the past, sequences listing in advance, follows the prescribed order, and order is broadcasted.In a single day the televiewer has missed former TV programme of expecting to see, just can only wait by the time the specific time is watched replay, or simply helplessly abandon the idea of watching.The main feature of interactive TV is it and user's interactive and programme content rich.But at present domestic also do not have a kind of interactive TV TV playback, watch current program, watch TV guide and provide function such as program prerecording to combine, in a system, let whole service assembly spectators watch more intuitive and convenient of interactive TV.

Summary of the invention

For give spectators more intuitive and convenient watch interactive television-o-experience; The invention provides a kind of interactive television system that comprises 9 days two-way EPG interfaces; Comprise 7 days programme distant informations that began the same day, added over 2 days 3 days the same day to review programme information and be incorporated in the EPG interface.Can watch the program of current broadcast through this interface user, can check, remind setting to 7 days programme distant informations, the setting of pre-recording, can also directly carry out reviewing in 3 days the program request of program and play, greatly facilitate user's viewing and experience.

EPG functional requirements in 9 days for terminal set top box are following:

1) comprised 9 days EPG information among the EPG in 9 days: contain and reviewed programme information at interior 3 days the same day, contain the same day at 7 days interior programme distant informations.

2) can operate as follows in the programme distant information at 7 days: get into and watch current playing program, following program is provided with prompting, following program setting is pre-recorded.

3) reviewed at 3 days and can select certain program in the programme information and play and watch.

On this EPG interface, can watch 7 days schedule information, and, can carry out program prerecording or remind operation through " service " key.Simultaneously can also be to the information of reviewing in past 3 days, and directly carry out program request and watch.

Embodiment

Below in conjunction with accompanying drawing, the present invention is done further description.In order to realize the system with 9 days EPG interface functions provided by the invention, need comprise a cover head-end system scheme and a terminal realization mechanism.

The EPG functional requirements in 9 days that the counterpart terminal STB need be realized, head end need be built the two-way EPG of cover system.

1.1 head end EPG data receiver formula

As shown in Figure 1,7 days programme distant informations derive from the SIG/SIInfo system in 9 days EPG data, review programme information in 3 days and derive from and review VOD system.

Two-way EPG system and SIG system and VOD system carry out the interface interconnection, obtain related data, and carry out the integration of the required EPG data of all kinds of business, finally offer terminal set top box with the XML form.After terminal set top box obtains, represented in the EPG interface at 9 days.

1.2 head-end system service logic

As shown in Figure 2, two-way HDEPG need realize that the EPG data generate, the EPG data are integrated, the EPG page is issued, four logical processes of EPG format management.

Below in conjunction with accompanying drawing the workflow at terminal is made detailed description.

2.1 the workflow of terminal access head end

The flow process of terminal set top box access head end system is as shown in Figure 3

2.2 the workflow of program is reviewed in the terminal program request

See 3 days on the terminal set top box and review programme information, and carry out program request and watch that its workflow is as shown in Figure 4:

1) STB gets into 9 days EPG interfaces, starts browser program.

When 2) STB selected certain to review program and carry out the program request operation, STB sent the HTTP order request to interactive terminal management system ICM, carries parameter S rvType, OffID, and uploads the STB relevant release note.

3) the ICM system obtains STB MAC number according to uploading information.

4) the ICM system generates ProtocolType information according to STB MAC number identification RTSP network environment.

5) the ICM system initiates to be redirected the HTTP request, carries parameters such as OffID, ProtocolType, is forwarded to program request Catalog publisher server.

2.3 the workflow that terminal program is reminded

Under 9 days EPG functions, it is as shown in Figure 5 that terminal set top box carries out the workflow of program reminding:

1) program that need to remind in the selection of the TV guide page of user sends program reminding information and gives STB, and shows the corresponding results page according to the return information of STB, can be following return information:

A. allow to remind

B. same time point reminds program that conflict is arranged

2) monitoring STB is reminded program information data, and when monitoring the current time when existing program to remind, send to browser and remind program-related information, and by the browser display confirmation page.

3) remind program if the user confirms to play, browser begins broadcast program.

2.4 the workflow that terminal program is pre-recorded

Under 9 days EPG functions, it is as shown in Figure 6 that terminal set top box carries out the workflow of program prerecording:

1) user needs recorded program in the selection of the TV guide page, and send performance recording information and give STB, and show the corresponding results interface according to the return information of STB, can be following return information:

A. allow to record

B. same time point program recording has conflict

2) detect mistake

3) the monitoring STB program information data of pre-recording when monitoring the current time when existing program to begin to record, is sent the program recording relevant information to browser, and by browser display confirmation interface.

4) if the user confirms program recording, browser will send confirmation and give STB, STB operation performance recording program.
