Fig. 3 is the using method flow chart of any one terminal (for example this terminal A) of this digital television program shared system 100.Shown in Fig. 3, the concrete using method of this terminal A is: first this terminal A is added one to share program user group (for example this shared program user organizes 41), the other-end (for example this terminal B, C, D) that by existing communication means such as UPNP, DLNA, WIFI, bluetooth, infrared transmission, this terminal A and this Set Top Box 20 and this shared program user is organized in 41 is all set up and is communicated by letter, thereby by organizing all terminal A, B in 41 with this shared program user, icon A1, B1, C1, D1 that C, D are corresponding are presented on the touch control operation interface of this terminal A.
Then, this terminal A will himself support that the TV programme form of playing sends to this Set Top Box 20.This Set Top Box 20 judges this terminal A supports whether the TV programme form of playing self supports that with this Set Top Box 20 the TV programme form of playing is identical, and determines that accordingly can this terminal A share the TV programme that this Set Top Box 20 is play.If this terminal A supports all TV programme forms of playing self to support that from this Set Top Box 20 all TV programme forms of playing are all different, this Set Top Box 20 judges that this terminal A can not share the TV programme that this Set Top Box 20 is play, and disconnects and the communicating by letter of this terminal A.If it is identical that this terminal A supports the TV programme form of playing self to support the TV programme form of playing to have at least a kind of with this Set Top Box 20, this Set Top Box 20 judges that this terminal A can share the TV programme that this Set Top Box 20 is play, and allows this terminal A to add the program shared mechanism of this digital television program shared system 100.Under this program shared mechanism, this Set Top Box 20 can periodically send user interface (User Interface to this terminal A with characteristic frequency, UI) information, the title of the TV programme of playing by this television set 30 such as this Set Top Box 20, duration, progress, brief introduction etc., and which terminal that this shared program user organizes in 41 is shared TV programme by this Set Top Box 20.This terminal A receives this UI information and shows on its touch control operation interface.In order to make touch control operation interface more succinct, can first not show the full text of this UI information, only by this message notifying district Z, can or the prompting mode such as flash with high brightness and remind to the user of this terminal A.When user clicks this message notifying district Z, this terminal A just shows the full text of this UI information on this touch control operation interface.In addition, the icon of sharing the terminal of program by this Set Top Box 20 can also be shown with colour or high brightness on touch control operation interface, and the icon of not sharing the terminal of program by this Set Top Box 20 is shown with black and white or low-light level on touch control operation interface, can reduce the word showing on touch control operation interface like this.
When user has added program shared mechanism by this terminal of the UI validation of information A receiving, in the time of can sharing TV programme by this Set Top Box 20, the other-end (for example B, C, D) that can utilize touch control operation interface and this shared program user to organize in 41 carries out interaction according to the details of sharing TV programme.In the present embodiment, the concrete mode of described " interaction " at least comprises following means: by this terminal A request, watch that any one in other-end B, C, D share the program of coming to watch from this Set Top Box 30; By this terminal A, invite any one in other-end B, C, D to share together and watch that this terminal A shares the program of coming to watch from this Set Top Box 30; Program of all not watching to any one the recommendation both sides in other-end B, C, D by this terminal A, and check any one details from these Set Top Box 30 shared programs in other-end B, C, D.Below with reference to Fig. 4 to Fig. 7, the detailed method of operation of above-mentioned several means is illustrated one by one.
Refer to Fig. 4, for example, when user wants to use this terminal A to watch that any one (this terminal B) in other-end B, C, D sharing the program of coming to watch from this Set Top Box 20, can be on touch control operation interface from icon B1 corresponding to this terminal B to icon A1 line corresponding to this terminal A.This terminal A senses after this line operation, to this Set Top Box 20, sends corresponding program sharing request, includes identification information corresponding to terminal B that sends the terminal A of program sharing request with this and be required to share program in this program sharing request.This Set Top Box 20 receives after this program sharing request, according to this identification information, determines this line operation starting point and terminal corresponding to terminal, and then judges that this is required whether the terminal B that shares program shares TV programme from this Set Top Box 20.If this terminal B does not now share TV programme from this Set Top Box 20, or this terminal B forbids that other-end synchronously shares self shared program, the program sharing request that this Set Top Box 20 this terminal of judgement A send is invalid, and send a miscue information to this terminal A, on the touch control operation interface of this terminal A, show.If this terminal B now shares TV programme from this Set Top Box 20, and allow this terminal A synchronously to share himself shared program, the program sharing request that this Set Top Box 20 this terminal of judgement A send is effective, the UI information that can send is immediately pointed out accordingly to the user of this terminal A, maintain line from this icon B1 to this icon A1 demonstration on the touch control operation interface of this terminal A simultaneously, with the user that reminds this terminal A at present this terminal A entered shared program state.Then, this Set Top Box 20 adds the multicast of shared TV programme (Multicast) address of this terminal B by this terminal A, this terminal A can accept the multicast Media Stream that this Set Top Box 20 sends, thereby shares same TV programme together with this terminal B.
Refer to Fig. 5, when using this terminal A to watch from this Set Top Box 20, user shares the TV programme of coming, and want to invite any one (for example this terminal C) in other-end B, C, D to watch together while sharing the program of coming from this Set Top Box 20, can on touch control operation interface, from icon A1 corresponding to this terminal A, to icon C1 corresponding to this terminal C, rule.This terminal A senses after this line operation, to this Set Top Box 20, sends corresponding message request, includes identification information corresponding to terminal C that sends the terminal A of message request with this and be invited to share program in this message request.This Set Top Box 20 receives after this message request, according to this identification information, determines this line operation starting point and terminal corresponding to terminal, and then judges whether this terminal C that is invited to shared program can share same TV programme at present together with this terminal A.For example, if this terminal C now can not (share same program together with this terminal A, this terminal C may share another by this Set Top Box 20 and pass through the different program of the shared program of this Set Top Box 20 from this terminal A), the message request that this Set Top Box 20 this terminal of judgement A send is invalid, and send a miscue information to this terminal A, on the touch control operation interface of this terminal A, show.If this terminal C now can share same program together with this terminal A, the message request that this Set Top Box 20 this terminal of judgement A send is effective, and the UI information that sends is to the touch control operation interface of this terminal C, inquires whether the user of this terminal C accepts this message request.If the user of this terminal C refusal is accepted this message request, this Set Top Box 20 sends a UI information to this terminal A, on the touch control operation interface of this terminal A, points out its invitation to be rejected.If the user of this terminal C accepts this message request, these Set Top Box 20 transmission one UI information are pointed out the user of this terminal A, maintain line from this icon A1 to this icon C1 demonstration on the touch control operation interface of this terminal A simultaneously, with the user that reminds this terminal A at present this terminal C entered shared program state.Then, this Set Top Box 20 adds the multicast address of shared TV programme of this terminal A by this terminal C, and this terminal C can accept the multicast Media Stream that this Set Top Box 20 sends, thereby shares same TV programme together with this terminal A.
Refer to Fig. 6, for example, when user wants any one (this terminal B) in other-end B, C, D sharing the program commending of coming to watch and for example, watch to the user of another terminal (this terminal C) from this Set Top Box 20, can be on the touch control operation interface of this terminal A from icon B1 corresponding to this terminal B to icon C1 line corresponding to this terminal C.This terminal A senses after this line operation, to this Set Top Box 20, sends corresponding recommendation information, includes with this and from this Set Top Box 20, share the terminal B of program and identification information corresponding to the terminal C of recommended shared program in this recommendation information.This Set Top Box 20 receives after this recommendation information, determines this line operation starting point and terminal corresponding to terminal, and then judge whether the terminal C of this recommended shared program can share same TV programme at present together with this terminal B according to this identification information.For example, if this terminal C now can not (share same program together with this terminal B, this terminal C may share another by this Set Top Box 20 and pass through the different program of the shared program of this Set Top Box 20 from this terminal B, or this terminal B refusal is synchronously shared program from this Set Top Box 20 with other-end), the recommendation information that this Set Top Box 20 this terminal of judgement A send is invalid, and send a miscue information to this terminal A, on the touch control operation interface of this terminal A, show.If this terminal C now can share same program together with this terminal B, the recommendation information that this Set Top Box 20 this terminal of judgement A send is effective, and the UI information that sends is to the touch control operation interface of this terminal C, inquires whether the user of this terminal C accepts corresponding recommendation.If the user of this terminal C refusal is accepted this recommendation, this Set Top Box 20 sends a UI information to this terminal A, on the touch control operation interface of this terminal A, points out its recommendation to be rejected.If the user of this terminal C accepts this recommendation, these Set Top Box 20 transmission one UI information are pointed out the user of this terminal A and this terminal B, maintain line from this icon B1 to this icon C1 demonstration on the touch control operation interface of this terminal A simultaneously, with the user that reminds this terminal A at present this terminal C entered shared program state.Then, this Set Top Box 20 adds the multicast address of shared TV programme of this terminal B by this terminal C, and this terminal C can accept the multicast Media Stream that this Set Top Box 20 sends, thereby shares same TV programme together with this terminal B.
As previously mentioned, icon B1, the C1 that user can show from the touch control operation interface of this terminal A, the show state of D1 (for example colour or black and white, high brightness or low-light level) understand other-end B, C intuitively, whether D shares program from this Set Top Box 20.Refer to Fig. 7, for example, if user thinks further to understand any one (this terminal B) in other-end B, C, D from the details of the shared program of this Set Top Box 20, such as the title of this program, duration, progress, brief introduction etc. can directly be clicked icon B1 corresponding to this terminal B on the touch control operation interface of this terminal A.This terminal A senses after this clicking operation, to this Set Top Box 20, sends corresponding inquiry request, includes identification information corresponding to terminal B being queried with this in this inquiry request.This Set Top Box 20 receives after this inquiry request, first judge whether this terminal B shares program from this Set Top Box 20, and whether this terminal B allows other-end inquiry self to share the details of program.If this terminal B does not now share program from this Set Top Box 20, or this terminal B does not allow other-end inquiry self to share the details of program, the inquiry request that this Set Top Box 20 this terminal of judgement A send is invalid, and send a miscue information to this terminal A, on the touch control operation interface of this terminal A, show.If now this terminal B shares program from this Set Top Box 20, and whether this terminal B allows other-end inquiry self to share the details of program, the inquiry request that this Set Top Box 20 this terminal of judgement A send is effective, and the UI information that sends is to the touch control operation interface of this terminal A, in order to show that this terminal B is from the details of the shared program of this Set Top Box 20.As previously mentioned, in order to make touch control operation interface more succinct, can first not show the full text of this UI information, only by this message notifying district Z, can or the prompting mode such as flash with high brightness and remind to the user of this terminal A.When user clicks this message notifying district Z, this terminal A just shows the full text of this UI information on touch control operation interface.When user runs through after this UI information, no matter on touch control operation interface, click any position outside this icon B1, can close this UI information.
Fig. 8 for example, for adding the terminal of this digital television program shared system 100 (this terminal A, B, C, D, E, F) flow chart of method of the program shared mechanism of this Set Top Box 20.Its concrete steps are as follows: first open the communication function of this Set Top Box 20, means of communication such as UPNP, DLNA, WIFI, bluetooth, infrared transmission, makes this Set Top Box 20 for example, set up and communicate by letter with the terminal (this terminal A, B, C, D, E, F) of appointment.Then, each is set up the terminal (this terminal A of take is example) of communicating by letter with this Set Top Box 20 and can send the request that adds program shared mechanism to this Set Top Box 20.As previously mentioned, this terminal A will himself support that the TV programme form of playing sends to this Set Top Box 20, in order to the program broadcast format that this Set Top Box 20 comparison this terminal A and this Set Top Box 20 can be supported self, and determine that accordingly can this terminal A share the TV programme that this Set Top Box 20 is play.If this terminal A supports all TV programme forms of playing self to support that from this Set Top Box 20 all TV programme forms of playing are all different, this Set Top Box 20 judges that this terminal A can not share the TV programme that this Set Top Box 20 is play, and disconnects and the communicating by letter of this terminal A.If it is identical that this terminal A supports the TV programme form of playing self to support the TV programme form of playing to have at least a kind of with this Set Top Box 20, this Set Top Box 20 judges that this terminal A can share the TV programme that this Set Top Box 20 is play, and allows this terminal A to add program shared mechanism.Now, first this Set Top Box 20 adds the relevant information of this terminal A in the terminal information table self storing.If there has been other-end to add program shared mechanism before, this Set Top Box 20 also can add the terminal of program shared mechanism to send UI information to these, is used for circulating a notice of the message that this terminal A adds program shared mechanism.Then, this terminal A can receive UI information from this Set Top Box 20, and by this Set Top Box 20 and other-end, according to the details of sharing TV programme, carries out interaction according to above-mentioned the whole bag of tricks.Afterwards, this Set Top Box 20 can continue according to the method described above new terminal to be added to program shared mechanism, also can receive the request of exiting program shared mechanism that has added the terminal of program shared mechanism to send, can also wait for other message relevant to self progress of work, such as the various system messages of sending from this digital TV network 10 simultaneously.The system message that new terminal adds the message of program shared mechanism, add message that the terminal of program shared mechanism exits and digital TV network 10 to send can send to all terminals in program shared mechanism by UI information by this Set Top Box 20.
Fig. 9 shows the whether effective concrete grammar of line operation on the touch control operation interface of using this Set Top Box 20 to judge each above-mentioned terminal (this terminal A of take is example).According to the method shown in Fig. 9, this terminal A experiences after line operation by its touch control operation interface, is about to corresponding signal of communication (routine program sharing request described above, message request or recommendation information) and sends to this Set Top Box 20.As previously mentioned, the identification information that this signal of communication comprises two terminals corresponding with the Origin And Destination of this line operation.This Set Top Box 20 receives after this signal of communication, extracts this identification information, and in the terminal information table of storing at himself according to this identification information, finds out the terminal corresponding with this line operation starting point and terminal.Then, first this Set Top Box 20 judges whether terminal corresponding to this line operation starting point is a terminal with TV programme playing function, and whether allows to share program.If terminal corresponding to this line operation starting point can not meet above-mentioned condition, this Set Top Box 20 is sent miscue by UI information to this terminal A.If terminal corresponding to this line operation starting point meets above-mentioned condition, these Set Top Box 20 these terminals of judgement are effectively line operation starting points, and continue to judge whether terminal corresponding to this line operation terminal is a terminal with TV programme playing function, and whether allow to share program.If terminal corresponding to this line operation terminal can not meet above-mentioned condition, this Set Top Box 20 is sent miscue by UI information to this terminal A.If terminal corresponding to this line operation terminal meets above-mentioned condition, these Set Top Box 20 these terminals of judgement are effectively line operation terminals, and then judge this line operation effectively.Now this Set Top Box 20 is upgraded corresponding UI information to record the situation of this line operation, and to this terminal A and belong to this shared program user together with this terminal A and organize all terminals of 41 and send the UI information of renewal, to circulate a notice of this line, operates.
Figure 10 shows the detailed step of " message that processing terminal sends by line mode " this operation in the flow chart shown in Fig. 8.Wherein said " message that terminal is sent by line mode " may be above-mentioned program sharing request, message request or recommendation information.Particularly, for example, when this Set Top Box 20 receives arbitrary terminal (this terminal A) of adding above-mentioned program shared mechanism and operates the program sharing request sent, message request or recommendation information by line, first this Set Top Box 20 judges according to the method shown in Fig. 9 whether the line operation on terminal A is effective.If this line operation is invalid, this Set Top Box 20 is sent miscue by UI information to this terminal A, and continue to wait for other by line, operate program sharing request, message request or the recommendation information of sending.If this line operation effectively, these Set Top Box 20 these line of comparison operate the program broadcast format that the related terminal of sharing program (i.e. the corresponding terminal of line operation terminal) the program broadcast format of supporting and the terminal (i.e. the corresponding terminal of line operation starting point) of asking to share program are supported.If the program broadcast format that these two terminals are supported is identical, this Set Top Box 20 directly adds the terminal of the shared program of this request the multicast address of the program being shared; If the program broadcast format that these two terminals are supported is different, first this Set Top Box 20 captures the Media Stream of this program being shared, the broadcast format of this program is converted to request and shares the program broadcast format that the terminal of program can be supported, the terminal of then this request being shared to program adds the multicast address of this program.Then, the terminal that this Set Top Box 20 can be shared program to this request by the media flow transmission of this program is play, and upgrades terminal information table and the UI table himself stored simultaneously.After this program finishes, message is exited in the terminal reception that this Set Top Box 20 is shared program from this request, again upgrades terminal information table and UI table, and adds the terminal of program shared mechanism to send relevant UI information to other.Complete after above-mentioned steps, what this Set Top Box 20 can continue to wait for other operates by line program sharing request, message request or the recommendation information of sending.
Figure 11 shows the detailed step of " inquiry request that processing terminal sends " this operation in the flow chart shown in Fig. 8.As previously mentioned, for example, for example, if add the user of arbitrary terminal (this terminal A) of program shared mechanism to think further to understand any one (this terminal B) in other-end B, C, D from the details of the shared program of this Set Top Box 20, can directly click icon B1 corresponding to this terminal B on the touch control operation interface of this terminal A.This terminal A senses after this clicking operation, to this Set Top Box 20, sends corresponding inquiry request, includes identification information corresponding to terminal B being queried with this in this inquiry request.This Set Top Box 20 receives after this inquiry request, first according to aforesaid means, judges that whether this inquiry request itself is effective.If this inquiry request itself is effective, this Set Top Box 20 judges that according to this terminal information table whether the identification information of this terminal B is effective.If the identification information of this terminal B lost efficacy, illustrate that this terminal B may in fact disconnect and the communicating by letter of this Set Top Box 20, now this Set Top Box 20 is by the user of UI information reminding terminal A.If the identification information of this terminal B is effective, this Set Top Box 20 is extracted the information relevant with the situation of this terminal B current shared program from this terminal information table to this UI table, by UI information, present case is informed to the user of terminal A.No matter whether the identification information of this terminal B is effective, when user runs through after current UI information, no matter on touch control operation interface, clicks any position outside this icon B1, can close this UI information, then carries out other operations.
