Abstract
The utility model discloses a digital mobile television capable of being installed conveniently, which comprises a signal receiving device, two WUSB controllers and a signal processing device, wherein the output end of the signal receiving device is connected with one WUSB controller; the two WUSB controllers are connected wirelessly; the other WUSB controller is connected with the signal processing device; the signal receiving device receives signals, converts the received signals into TS streams, and transmits the TS streams to one WUSB controller, and the WUSB controller converts the TS streams to wireless signals for transmission; the other WUSB controller wirelessly receives the wireless signals, converts the wireless signals into TS streams and transmits the TS streams to the signal processing device; and the signal processing device receives and analyzes the TS streams, extracts and decodes the audio and video signals and transmits the signals to a audio and video player for play. The digital mobile television provided by the utility model is excessively convenient in installation, and additionally the cost can be saved.
Description
Technical field
The utility model relates to TV technology, particularly a kind of convenient digital moving-tv of installing.
Background technology
The digital moving-tv technology is a kind of technology of new develop rapidly, and China almost all builds up or open the digital moving-tv network in medium above city.
Existing digital moving-tv mainly comprises antenna, set-top box, playing audio/video, as shown in Figure 1, mainly includes tuner, demodulator, audio/video decoder and CPU processor etc. in the set-top box.The operation principle of present digital moving-tv is: behind the antenna reception HFBC high frequency broadcasting signal, tuner in set-top box is with the high-frequency signal amplification and reduce to intermediate-freuqncy signal, intermediate-freuqncy signal becomes the TS code stream with certain coded format after the demodulator demodulation, the CPU processor extracts the audio/video information in the TS code stream, after the audio/video decoder decoding, by the playing audio/video broadcast program.
Because what the signal that digital moving-tv receives used is broadcast band, wavelength is longer, in order to reach good reception, required antenna size is larger, antenna places car outer or outdoorly more be conducive to receive signal, antenna is connected with set-top box in the prior art, and set-top box and playing audio/video need to carry out wired connection, and such connection is so that install very inconvenient; Tuner, demodulator, audio/video decoder and CPU processor etc. all are installed in the set-top box in addition, because the standard of digital moving-tv is a lot of now, different standard-required demodulators is also different, so when the digital moving-tv ground standard changes, must change demodulator, but these functional modules such as demodulator, tuner, audio/video decoder and CPU processor all are arranged on the same circuit board, then need to change whole circuit board, even whole set-top box, so Expenses Cost very.
Summary of the invention
The purpose of this utility model has provided a kind of convenient digital moving-tv of installing, and it is easy for installation, and when reducing the digital moving-tv standard and changing to the replacement cost of equipment.
In order to realize goal of the invention, the technical solution of the utility model is:
A kind of convenient digital moving-tv of installing comprises: signal receiving device, two WUSB controllers and signal processing apparatus; The output of signal receiving device is connected with one of them WUSB controller, these two WUSB controllers wireless connections, and another one WUSB controller is connected with signal processing apparatus;
Signal receiving device receives signal and converts the signal that receives to the TS code stream, and is transferred to one of them WUSB controller, and this WUSB controller is converted to wireless signal with this TS code stream and sends; This wireless signal of another one WUSB controller wireless receiving, and change into the TS bit stream to signal processing apparatus, signal processing apparatus receives and resolves described TS code stream, is sent to audio and video display device after extraction audio-video signal and the decoding and plays.
Digital moving-tv of the present utility model, the output of signal receiving device be connected the WUSB controller and connect, another one WUSB controller is connected with signal processing apparatus, so signal receiving device has been realized wireless connections by two WUSB controllers and signal processing apparatus so that the digital moving-tv of utility model install very convenient; When the digital moving-tv standard changes, only need to change to comprise that the signal receiving device of demodulator gets final product, and provides cost savings greatly in addition.
Description of drawings
Fig. 1 is the schematic diagram of digital moving-tv of the prior art;
Fig. 2 is the utility model digital moving-tv schematic diagram in one embodiment.
Embodiment
Below just with specific embodiment the utility model is done a detailed introduction by reference to the accompanying drawings.
Such as Fig. 2, digital moving-tv of the present utility model, it comprises: signal receiving device, two WUSB controllers and signal processing apparatus; The output of signal receiving device is connected with one of them WUSB controller 1, these two WUSB controllers wireless connections, and another one WUSB controller 2 is connected with signal processing apparatus;
Signal receiving device receives signal and converts the signal that receives to the TS code stream, and is transferred to one of them WUSB controller, and this WUSB controller is converted to wireless signal with this TS code stream and sends; This wireless signal of another one WUSB controller wireless receiving, and change into the TS bit stream to signal processing apparatus, signal processing apparatus receives and resolves described TS code stream, is sent to audio and video display device after extraction audio-video signal and the decoding and plays.
Above-mentioned WUSB controller is a kind of radio transmission apparatus, can realize wireless transmission sound, image etc., and its transmission speed can reach 480Mbit/s, and requires transmitting power lower, and the WUSB controller can provide a lot of interfaces, and parallel and serial line interface are arranged.
Digital moving-tv of the present utility model can be the vehicle-mounted digital mobile TV, signal receiving device is connected with one of them WUSB controller 1 and is installed in outside the car, another WUSB controller 2 is installed in the car with signal processing apparatus and audio and video display device, because of the wireless connections of two WUSB controllers, so need not consider car is carried out transformation on the line, so that digital moving-tv of the present utility model is very convenient when installing onboard.Because the signal receiving device in the utility model is very low at the shared cost of whole digital moving-tv, when the digital moving-tv standard changes, need to change the signal receiving device that comprises demodulator, greatly reduce cost.
Above-described the utility model execution mode does not consist of the restriction to the utility model protection range.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection range of the present utility model.
