In the prior art, mostly the reception decoding device of media signal is the reception decoding device to the function singleness of signal specific.A kind of dual-mode set-top box occurs on the market recently, can realize IPTV and cabled digital broadcast reception.But can not receive the digital broadcast signal of ground and satellite, realize the reception of multiple signal, the user need dispose plural STB, not only uses inconvenience, has also increased cost.
In addition, consider that one family has multiple TV set, need a plurality of STB be provided, configuration one to one between STB and TV respectively for these television sets.Therefore, the user will bear more financial burden usually.
The system that STB can drive a plurality of analog or digital TV has the competitive advantage of the interest that causes the user on price and performance, therefore provide a kind of new-type network TV STB that drives the system of a plurality of analog or digital TV to become present technique field technical problem anxious to be solved.
Summary of the invention
Therefore, the utility model proposes a kind of STB of supporting multi-display, can eliminate fully because the restriction of prior art and one or more problems that defective causes.
The purpose of the utility model provides a kind of STB of supporting multi-display, through this STB, only uses a STB just can realize watching from a plurality of user's display devices the home network TV of digital broadcasting.
The utility model additional advantage, purpose and characteristic; A part will be illustrated in the specification below, and another part will be tangible for those of ordinary skill in the art through the investigation to following explanation or from the enforcement of the utility model, acquire.Structure through in the specification of literal and claims and accompanying drawing, pointing out especially can realize and obtain the utility model purpose and advantage.
In order to realize these purposes and to obtain other advantage and, as giving practical implementation and broadly described at this, comprise according to the STB of support multi-display of the present invention according to the object of the invention:
Receiving element is used to receive the multiplex broadcasting signal;
A plurality of user's display devices are used to show the broadcast singal that receives;
Control unit is used for basis from the remote signal that user's display device receives, and controls desired broadcast singal and is transferred to corresponding user's display device respectively;
Allocation units are used for according to the control signal of control unit broadcast singal being transferred to corresponding user's display device.
According to the utility model one preferred embodiment, said control unit adopts the SoC chip to constitute.
According to the utility model one preferred embodiment, the embedded (SuSE) Linux OS of said control unit.
According to the utility model one preferred embodiment, said control unit identification is given corresponding user's display device from the ID of the control signal that each user's display device receives to transmit corresponding broadcast singal.
According to the utility model one preferred embodiment, this Web TV STB further comprises memory cell, is used to store each user's log or status file.
The beneficial effect of the utility model is: just can receive ground, wired and satellite digital broadcasting and have the function of IPTV through a STB, have powerful, the advantage that cost is low.
Description of drawings
Fig. 1 is the block diagram according to the Web TV STB 1 of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment of the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is the block diagram according to the Web TV STB 1 of the utility model embodiment.
With reference to Fig. 1, Web TV STB 1 comprises tuner 101, SoC chip 102, video encoder 103, audio D/A converter 104, infrared receiving processor 105, distribution module 106 and memory module 107.Wherein, SoC chip 102 (as, the PNX8550 of PHILIPS company) be the core processing part of whole system, all control is handled and is all accomplished these SoC chip 102 embedded (SuSE) Linux OS by SoC chip 102.
This tuner 101 comprises: the DMB-TH tuner is used to receive terrestrial television; The DVB-C tuner is used to receive cable TV; The DVB-S tuner is used to receive satellite television; 101 pairs of radiofrequency signals that receive of tuner are carried out demodulation, demodulate TS stream signal, and TS stream signal is imported into SoC chip 102; SoC chip 102 will unpack from the Streaming Media process that network is sent here, solves video program stream and audio program streams, and passes through software in SoC chip 102 inside; Solve the video data of checking the ITU56 standard; Data are sent to video encoder 103 (model is PNX 8510 among the figure), weave into meet vision signal, S-VHS signal and the component video signal of simulation and export, simultaneously with the audio program streams decompress(ion); Solve audio digital signals; This audio signal is sent to audio D/A converter 104 (model is WM8731L among the figure), and through the D/A conversion, the output analogue audio frequency is stereo.Infrared receiving processor 105 receives the control signal that IR remote controller is sent, and is sent to SoC chip 102 after treatment.Distribution module 106 distributes broadcast singal to give each user's display device 201,202,203 respectively according to the control signal of SoC chip 102.
Web TV STB 1 also can send data to each user's display device 201,202,203 and receive the data from each user's display device 201,202,203 through LAN/WAN card, HomePNA2.0 card etc.
Web TV STB 1 receives remote signal from each user's display device 201,202,203, and corresponding service is provided then.
So implement, can be from comprising current broadcast channel switch/watch, the watching of medium, PVR (personal video record) function, tableaux, image zoom is selected corresponding service in the group of internet browsing service etc.
What for example, describe below is the example that user's display device 201-TV1 receives terrestrial broadcasting.
At first, after receiving remote control (R/C) signal that requires ground broadcast signal through LAN/WAN card, HomePNA2.0 card etc. from TV1, the R/C signal is imported into the SoC chip 102 of Web TV STB 1.So, SoC chip 102 identifies the ID of corresponding TV1 from the R/C signal of being imported.And the operation of SoC chip 102 Control Allocation modules 106 is so that the broadcast singal that receives and handled by SoC chip 102 through tuner 101 can send TV1 to.
Distribution module 106 is given TV1 according to the control of SoC chip 102 through LAN, WAN or the corresponding broadcast singal of RF cable transmission, thereby ground broadcast signal can be transferred to TV1.
Thereby the user can watch the TV1 that shows this specific terrestrial broadcasting.
Simultaneously, when the user watches the TV1 that shows this specific terrestrial broadcasting, but other assembly TV2 and TV3 receiving satellite broadcast, wired broadcasting, terrestrial broadcasting or the like.
The channel that the user of each user's display device watches, medium etc. can be learnt through the log or the status file that are stored in the user's display device in the memory module 107 among the Web TV STB 1 respectively.
As stated, the STB according to support multi-display of the present invention can make a STB provide various digital broadcastings to several user's display devices.
Therefore, and provide the mode of the prior art of a plurality of Web TV STB to compare respectively for a plurality of user's display devices, the utility model can reduce user's burden.
In the above-described embodiments, only the utility model has been carried out exemplary description, but those skilled in the art can carry out various modifications to the utility model after reading present patent application under the situation of spirit that does not break away from the utility model and scope.
