Embodiment
At first simply describing overall plan of the present invention according to Fig. 1, is that example provides with the DTV STB.The cable TV signal that comes automatic network is through the tuner frequency-selecting, the QAM modulation, and ATM handles the back outputting video streams, after the MPEG-2 video decoder decodes, gives PAL/NTSC/SECAM system encoder again to obtain the vision signal of corresponding format.In this process, the figure signal such as menu that the pattern generator that can superpose produces.Audio stream is converted into simulated audio signal by MPEG-2 decoding back by audio frequency D/A.Data flow passes to CPU, does corresponding processing by CPU, and for example CPU controls pattern generator according to the menu graphical data in the data flow and produces menu graphical.CPU also selects to produce corresponding message data according to the user, after QPSK or QAM modulation, feeds back to video server by up channel.
The business information of in the transmission stream (TS) of DTV, inserting (SI) has been carried the required total data of EPG.SI is inserted by related standards as long as broadcast front end, the receiving terminal decoder just can take out SI from TS, constitutes the EPG of difference in functionality.Under the ever-increasing situation of digital television business, it is very inconvenient that the user can feel when selecting business.If can user's information needed be organized in order, provide similar program newspaper, again can be on television set the function of instantaneously browsing, will be user-friendly to greatly.EPG just in time can play this effect.
To the requirement of EPG, EPG should provide basic functions such as programme and current playing programs according to " digital TV broadcasting service information standard ", and Premium Features such as program additional information, program classification, program booking and parental ratings control also can be provided.In interactive television, EPG is more complicated, should be able to provide such as functions such as programme content background information, visual angle switching, weather forecast, recreation.These functions of EPG all can realize through the data that SI provides.That is to say that SI is the prerequisite that realizes the EPG function.In the SI table, the most important thing is NIT, EIT and SDT, utilize the data in these 3 tables just can construct the different EPG of function.
As stated, EPG is used for making user's information needed to organize in order.Existing DTV STB; Usually the mode that adopts is a taxonomic organization, takes the form of network, audio broadcasting, TV and video request program or approximate video request program, and the switching between them is through the selection key on main menu or the remote controller; Owing to be the switching between the different program category; Its operation is slow, and also must select once more after switching, and just can find the content or the program that need.
Because all services of digital television broadcasting all are to organize transmission in an identical manner, in fact select just passable as long as the confession user is listed in these services.According to the actual search process, the service that searches is provided in order, as shown in Figure 2.For order program service, we with all time periods of a program as a service processing.Here be that example is described innovative idea of the present invention with eight services.These eight services have comprised contents such as network, broadcasting, TV, video request program basically.
For continuous handed over service, on remote controller, be provided with two button services+and service-, if eight top services all in circulation, utilize these two buttons just can all services of fast browsing.Because the service that provides of DTV is many, if all services all are placed in the circulation, traveling through all services is a more time-consuming thing, for this reason, the menu that utilizes Fig. 2 to provide, the user can be provided with this service whether in circulation.The realization of these operations is very easy as far as prior art; At first access this menu; The directionkeys that utilizes remote controller moves on to the service adjusted wanted with cursor, press acknowledgement key just can be and not between switch back and forth, the storage relative set is to E when withdrawing from menu
2PROM.The flow chart of Fig. 7 has shown presses the flow chart of seeking next service in round-robin queue behind service+key; If next service is not in round-robin queue; Then read the circulation setting of next service; Till finding,, then stop to seek and do not carry out handover operation if all do not find after traveling through all services.
When service that the user will dislike from circulation after the deletion, pressing service+and service-these two buttons will in the service of being left, circulate, as shown in Figure 3.Current service shows as shown in Figure 4 on screen.
If the current service that switches to is order program service (NVOD); System can be with providing in each time period of broadcasting of current program and the menu of form below screen of each time period that will broadcast in the future with tabulation; Can select to switch to the time period user who is broadcasting, the time period user that plan is broadcasted can select to be scheduled to.Because program request is a time shift program, can also come the fast browsing time shift program through F.F. and two buttons of rewind down that on remote controller, are provided with the synchronization user.F.F. and rewind down, the F.F. and the rewind down function of imitating DVD player exactly.With the F.F. is example, as shown in Figure 6, when request program is play; The user presses fast forward button; Then system broadcasted plan the last time period of this program of removal search from the timetable of this program, if there is a time period, then switched to the program of this time period broadcast; Because it is Zao that the program of the current broadcast of ratio that a last time period begins to broadcast is wanted, the user just can see the content of this program back fast like this; If there is not the program of a time period broadcast, just current program is that early start broadcasts in all time periods of this program, and the F.F. action is not just carried out.Otherwise; If press the rewind down button; System broadcasts plan the next time period of this program of removal search from the timetable of this program, if the program of next time period does not also begin to broadcast or the program of current broadcast is exactly the last time period, the rewind down action is not just carried out; If the program of next time period broadcasts, system switches to this time period, and the user just can see the content of this program front fast like this.So just can realize fast browsing to current request program.Because more than one of the program of program request, also be provided with on the remote controller and turn over and turn over two buttons down, press the directly circulation switching in different request programs of these two buttons.If the service of pressing this moment+or service-, then be directly switch to the next or last service in the circulation that sets.As when advancing into service 8, corresponding is variety 2 programs of program request column, so no matter how in all request programs, how to switch, and pressing service+, get into service 1, i.e. CCTV-1, the service of pressing-, entering serves 7, and promptly variety 2.F.F. and rewind down also can not be provided with button separately, choose the corresponding button to confirm that system carries out operation noted earlier through on screen, showing " F.F. " and " rewind down " two buttons, user.In addition, can also let system get into the fast forwarding and fast rewinding state, get into, multiplexing in this state " taking+" and " service-" button, thereby the operation above realizing as triggering through a button.
If the current service that switches to is the network service, like the weather forecast column, system shows current bibliographic structure in the bottom, as Shenzhen wired-urban life-weather forecast.In general, the column that system provides is relatively-stationary, and the switching that upturning key that the user can provide through system and downturning key carry out column is browsed.If the service of pressing this moment+or service-, no matter how in the all-network service, how to switch, then be directly switch to the next or last service in the circulation that sets.
If current what switch to is TV or broadcast program, the order that upturning key that the user can provide through system and downturning key carry out TV or broadcast program is browsed.If as this moment pressing service+or the service-, then be directly switch in the circulation that sets the next one or a last service.
Can find out from top description, service+and service-key realized the switching of dissimilar services comprising upturning key and downturning key have been realized same type of service at interior navigation keys switching.For quick switching, with these four buttons and " affirmation " key layout together, as shown in Figure 5.
Because the service that DTV provides is many, if just begun all services are all added circulation, efficient is lower in the time of can causing utilizing circulation to be switched, and editor is relatively more difficult.Reasonable method is the basis of switching as circulation with TV programme, and the service of other type is implemented in the switching in the circulation through the method that adds circulation.The service of other types is added circulation, can add singly,, also can whole type add together, as the broadcast type program being done as a whole add together circulation or deletion from circulation together as being provided with one by one through menu shown in Figure 2.
In addition, add circulation or deletion from circulation for ease, a circulation can be set on remote controller key is set, when certain service is broadcasted, press this key, make this service add circulation or deletion from circulation.
