Embodiment
Below with reference to accompanying drawing the preferred embodiments of the present invention are described.In the accompanying drawing of institute's reference, parts identical among the different figure represent with identical drawing reference numeral.
Referring to Fig. 1, be the composition schematic diagram of a specific embodiment of TV signal playing network system among the present invention.This network system comprises receiving system 10, the first player 11, IGRS's TV service end 12 and the second player 13.Wherein, receiving system 10 is used for receiving at least two-way TV signal by at least two tuners; The first player 11 is used for playing the TV signal that described receiving system 10 receives; IGRS's TV service end 12 is used for based on IGRS protocol the TV signal that described receiving system 10 receives being sent to the second player.
In having the Digital Television of picture-in-picture function, Digital Television namely comprises above-mentioned receiving system 10, the first player 11 and IGRS's TV service end 12, and at this moment, what the first player 11 was play is the digital television signal that the receiving system 10 after processing receives.The first player can be play one tunnel TV signal or play simultaneously the two-way TV signal according to TV user's needs (is picture-in-picture, but wherein one tunnel TV signal can only be play picture, the sound signal of this road TV signal can not be play by the loudspeaker by TV, but in some PIP in addition the Audio Players such as lug machine play this road sound signal).Simultaneously, the multi-channel TV signals that receives of receiving system 10 can send to the second player 13 by IGRS's TV service end 12 via other transmission channels and plays with the TV signal that sends to the first player 11 is non-interfering.
And in the TV that uses the set-top box playing digital television signal, as shown in Figure 2, described set-top box 100 comprises receiving system 1001, IGRS's TV service end 1002 and the first sending module 1003.Wherein the receiving system 10 among receiving system 1001 and IGRS TV service end 1002 and Fig. 1 is consistent with the function of IGRS TV service end 12, and the first sending module 1003 is used for that the TV signal that described receiving system 1001 receives is sent to the first player 11 and plays.Common simulated television then is the first above-mentioned player 11, set-top box 100 sent to the first player 11 with TV signal by the first sending module 1003 and play this moment, and what the second player 13 was play then is the TV signal that sends via other transmission channels by IGRS's TV service end 1002.
Wherein, IGRS's TV service end 12 specifically can comprise: receive submodule, be used for receiving connection request and the programme content selection message that described the second player sends; Obtain submodule, be used for selecting message to obtain corresponding concrete TV signal according to the described programme content of accepting the submodule reception; Send submodule, be used for obtaining the concrete TV signal that submodule obtains and sending to the second player described.
The second player 13 is used for sending connection requests and programme content is selected message to described IGRS TV service end 12, receives and play the TV signal that described IGRS TV service end 12 sends after connecting with described IGRS TV service end 12.The second player 13 can be the equipment of supporting other TV signal play of IGRS protocol, such as being another number of units word TV (this Digital Television not necessarily has the function of picture-in-picture), also can be PC.The example that the reciprocal process of the second player 13 and IGRS's TV service end 12 can see below is not done herein and is given unnecessary details.
With reference to figure 3, be the composition schematic diagram of a specific embodiment of TV signal playback equipment among the present invention.This equipment can comprise receiving system 20, the first player 21, IGRS's TV service end 22, and wherein, the function of each concrete device and composition can be referring to the corresponding devices of each shown in Fig. 1.This TV signal playback equipment can be to have the Digital Television of picture-in-picture function or comprise television broadcasting system (namely comprising set-top box and common simulation TV) of set-top box etc.
Simultaneously, specific embodiments of the invention also provide a kind of TV signal player method, and as shown in Figure 4, the method comprising the steps of:
Step S401, receive at least two-way TV signal by at least two tuners.This TV signal comprises audio signal and vision signal.
Step S402, the TV signal of described reception is play by the first player.The signal demand that tuner is received carries out just converting Voice ﹠ Video output to after a series of processing and plays, as shown in Figure 5, it is the process that the signal that a tuner receives is processed, the i.e. tuning demodulation of a tuner process obtains the digital TV transmission stream (TS stream) of certain frequency, this frequency comprises TV user and wants the program watched, then filter out the elementary stream of the program that the user need to see through demultiplexing, in the situation that be necessary, need to decode through behind the descrambling, the processing such as sound audio video synchronization, the signal after then will processing outputs to respectively on sound card and the display screen.For the TV with picture-in-picture function, what play can be that (but wherein one tunnel TV signal can only be play picture to the two-way TV signal, the sound signal of this road TV signal can not be play by the loudspeaker of TV, but in addition the Audio Players such as lug machine is play this road sound signal in some PIP), also can be one tunnel TV signal.
Step S403, based on IGRS protocol the TV signal of described reception is sent to the second player and play.This step can be carried out simultaneously with step S402, after namely in step S401, receiving TV signal by two above tuners, the TV signal after processing can be distributed to simultaneously non-interfering broadcast of the first player and the second player by different passages.
This step specifically can be referring to the flow chart shown in Fig. 6.Wherein, the second player comprises IGRS's TV client (IGRS AV Client) of supporting IGRS protocol.Can be to its IGRS's TV service end of serving (IGRS AV Server) in the client search network in the second player, and send connection request to service end.After service end and client connect, the programme of the TV signal that receives among the step S301 can be sent to client, i.e. the second player is wanted the program play by user selection, as being program A among Fig. 6.If the first player is the player of support picture-in-picture, then this programme can be the information of current in progress two TV programme of the first player.The second player sends to service end with the information of the program of user selection, and as being program A selection message among the figure, then service end is obtained the TV signal of program A after receiving this message, and sends it to the second player.The second player is play after this TV signal is necessarily processed (such as audio-visual synchronization etc.).
Additionally do not increasing on the basis of hardware cost like this, just can play the content of TV program different from the first player by IGRS technology the second player, realizing non-interfering share of multi-channel TV signals between different players.Even and the first player transfers platform also can not affect the broadcast of the current program of the second player.The second player can be portable terminal, PC or other TV, like this a TV is expanded to two even more (as long as IGRS's TV service end is supported a plurality of IGRSs TV client), and can be arbitrarily mobile in the network range that service end covers, as in the family, can be in the bathroom, the place such as bedroom, study televiews, and on the television-viewing of the first player without any impact.
Above disclosed is a kind of preferred embodiment of the present invention only, certainly can not limit with this interest field of the present invention, and the equivalent variations of therefore doing according to claim of the present invention still belongs to the scope that the present invention is contained.
