Abstract

A method for automatically display the data of broadcast program list for digital TV set includes setting up if the broadcast program list is automatically displayed, detecting the data of broadcast program list to be displayed, and displaying the broadcast program list.

Description

The method of the automatic display of broadcast information program forms data of digital television

[technical field]

This is about being on the digital television at digital broadcasting transmitter, automatically a method of display of broadcast information program list.More particularly, it is about in the current program end of watching the user, next program or about the automatic method that shows of other broadcast program information.

[background technology]

Fig. 1 shows the brief block diagram of the internal structure of digital television.

Below, the structure of digital broadcasting transmitter is described with reference to Fig. 1.

At first, as the digital television of digital broadcasting transmitter,, be the digital broadcast signal that unit receives the bit stream form with the packets of information by the tuner and the VSB (130) of digital television, it is transformed into transmits stream (transport stream) form then.Transmit the packets of information formation of stream, and each packets of information is divided by the intrinsic number (packet ID) of packets of information with 188 bytes.In addition, in such transmission stream, comprising is the data of program services such as television broadcasting, data broadcasting, and electronic program information list (electronic programming guide; To call " EPG " in the following text) etc.

This transmits the signal of stream form, by demultiplexer (Transport Demultiplexer; 140) be separated into picture signal row, acoustic signal row and additional information signal row respectively.Wherein, the picture signal row are sent to MPEG A/V decoder (150), and compressed picture signal are expanded and restored; The acoustic signal row are sent to AC-3 decoder (160), and compressed acoustic signal are expanded and restored; The additional information signal row are sent to CPU (100), and it are deposited into memory (110) as a kind of information that shows by graphical user interface (GUI).

CPU (100) is by bus (bus) and I ²C goes to control whole action.EEPROM (Electrically Erasable Programmable Read Only Memo) (EEPROM:170) under the state of power cutoff, is removed record and is stored data necessary.Programmable logic device EPLD (180) is a digital logic chip, and it will be with the signal that generates when control necessity.

Fig. 2 shows, and is included in the EPG picture menu map that transmits broadcast message playbill data in the stream.As shown in Figure 2, the menu of user by the EPG picture, projection time, the program that can the obtain program information that people (TV station) is provided and shows time etc.

But when time that the program that has arrived current broadcast finishes, the user just can recognize the broadcast information of other channel of current time by the action button of remote controller or TV, maybe can know the broadcast order that current broadcast items is later.That is, when having arrived the program end, need the user to obtain the TV program information of needs with the manual operation button.Like this, the user can feel very inconvenient.And, along with broadcasting increasing of channel quantity, the more difficult program that goes to understand other channel broadcast.

[summary of the invention]

In order to solve the problem of above-mentioned existence, the objective of the invention is to, a kind of method will be provided, can be before current program will finish, to can automatically demonstrate the television programming sequence that will broadcast after the current channel with the form of picture, and the TV program information of other channel of current time.

In order to achieve the above object, the automatic display packing of digital television EPG of the present invention has the feature of following several stages.That is: (a) setting stage: this is before the current TV programme of broadcasting finishes 1 minute, sets the stage of whether removing to determine automatic broadcast program information single (EPG); (b) detection-phase: this is to detect the preceding 1 minute stage that program will finish; (c) the demonstration stage: this is in (a) stage, wants automatic display of broadcast information program list if set, so just will detect the preceding 1 minute clock time that program will finish, and will demonstrate the stage of broadcast message playbill data.

At this moment, preferably take following method.That is, in the stage, add a stage, only go to select one so that reach in " later program broadcast order " among both of " other passage program broadcasts information " at (a).If set " later program broadcast order ", the order of the program after (c) stage will finish current television program is presented on the picture of OSD so.If set " other passage program broadcasts information ", will the programme information of other channel TV of current time be presented on the picture of OSD in (c) stage so.

By the present invention, before the current TV programme broadcasted finishes 1 minute, later broadcast in proper order or the broadcast information of other channel, automatically be presented on the OSD picture.So, can make the user obtain TV program information very easily, needn't take channel switch or remote controller in addition.

Effect of the present invention is: according to the present invention, the user of Digital Television shows automatically by EPG is set, and when broadcast items will finish, can obtain the TV program information of other channel easily, or later program

Fig. 4 is OSD picture figure under the various situations to Fig. 7.

[embodiment]

Fig. 4 shows the OSD picture (400) that whether will set automatic display of broadcast information program forms data.The user of digital television, at first select " automatically broadcast message programme " on the OSD picture after, can reach in " other channel program broadcast information " in subdirectory project " later program broadcast order " and only select 1 to set.

With reference to Fig. 3 as can be known, the automatic display packing of EPG of the present invention is made up of following several stages.That is, at first understand whether be provided with before the current TV programme of broadcasting finishes 1 minute, automatically single (EPG) data (stage 300) of display of television programmes information.If automatic display of broadcast information program list is not set, then to turns back to original picture and stop (stage 380) afterwards again.

Then, detect the preceding 1 minute moment that program finishes.Finish preceding 1 minute moment in order to detect program, remove to receive the signal (stage 310) of the announcement " program finishes preceding 1 minute " that TV station sends, perhaps from the data of broadcast message programme, go to retrieve program end time (stage 322), calculate current broadcast items then and finish the preceding 1 minute time (stage 324).

If, do not receive the signal of the announcement " program finishes preceding 1 minute " of TV station, or do not have the broadcast message playbill data, so just the OSD picture of control information is presented on the picture, turn back to original picture (stage 380) then.Fig. 5 shows the OSD picture (520) of the demonstration control information that " do not have concluding time information ".Reference symbol shown in Fig. 5 510 in addition, the picture of pointing out current channel and being set with the TV program information list.

Then, if arrived preceding 1 minute that program finishes, so just go to understand whether be provided with " later program broadcast order " (stage 350).If set, so just from the broadcast message playbill data, retrieve the current TV programme of broadcasting and finish to begin to broadcast the program of having set (stage 360).Fig. 6 shows the OSD picture (600) of " later program broadcast order ".

If, do not set " later program broadcast order ", from the data of programme, retrieve other channel program so and broadcast information, and it is presented at (stage 362) on the OSD picture.Fig. 7 shows the OSD picture (700) that other channel program broadcasts information.

Then,, or arrived the time that program finishes, so just turned back to original picture (stage 370) if imported the push-botton operation signal from the outside.
