Abstract
The utility model relates to a radio satellite television transceiver, which is characterized in that the radio satellite television transceiver comprises a satellite digital television set top box, the radio satellite digital television set top box is directly connected with a low-noise down-conversion module which is used for receiving satellite digital television signals, a radio transmitting module is built in the radio satellite digital television set top box, the radio transmitting module modulates decoded high-definition digital television signals and transmits the signals to a space, the radio satellite television transceiver additionally comprises a radio receiving module, the radio receiving module demodulates the modulated signals transmitted by the radio transmitting module into high-definition video signals and the high-definition video signals are played through play equipment of a receiving terminal. By adopting a radio transmitting and receiving method, cable connection is avoided, signal attenuation is avoided and signal receiving sensitivity is greatly improved.
Description
Technical field
The utility model relates to satellite television receiving system, is specifically related to a kind of radio satellite TV transceiver.
Background technology
Present satellite television receiving system normally links to each other with indoor satellite digital television receiver set top box by cable by being arranged on outdoor low noise down conversion module (LNB).Because the higher outdoor environment of adding of output frequency of low noise down conversion module (LNB) is abominable, signal must have certain decay in cable, has so just reduced the sensitivity that signal receives.
Summary of the invention
The purpose of this utility model provides the radio satellite TV transceiver that a kind of loss of signal is little, receiving sensitivity is high.
For achieving the above object, the utility model has adopted following technical scheme: the utility model comprises satellite digital television receiver set top box, described satellite digital television receiver set top box links to each other with the low noise down conversion module of receiving satellite word TV signal, the built-in wireless transmitter module of satellite digital television receiver set top box, the space is modulated and be transmitted into to described wireless transmitter module with decoded digital TV in high resolution signal, this device also comprises wireless receiving module, and the modulated signal of wireless transmitter module emission is demodulated into the high-definition audio and video signal to described wireless receiving module and the playback equipment by receiving terminal plays back.
As shown from the above technical solution, adopt the form of wireless receiving and dispatching to avoid the cable connection, thereby also avoided the decay of signal, improved the sensitivity that signal receives greatly.
Description of drawings
Fig. 1 is the theory diagram of a kind of execution mode of the present utility model.
Embodiment
As shown in Figure 1, this device comprises satellite digital television receiver set top box 1, described satellite digital television receiver set top box 1 links to each other with the low noise down conversion module of receiving satellite word TV signal, satellite digital television receiver set top box 2 built-in wireless transmitter modules 2, the space is modulated and be transmitted into to described wireless transmitter module 2 with decoded digital TV in high resolution signal, this device also comprises wireless receiving module 3, and the modulated signal of wireless transmitter module 2 emission is demodulated into the high-definition audio and video signal to described wireless receiving module 3 and the playback equipment by receiving terminal plays back.
In existing satellite digital set-top box, add wireless transmitter module 2, avoided wire cable to be connected by wireless transmitter module 2 with the wireless connections of wireless receiving module 3, thereby also avoided the decay of signal, improved the sensitivity that signal receives greatly.Transmission range of the present utility model≤30 meter are even large-area house and compound floor also can both be suitable for.
Described wireless receiving module 3 can be set to a plurality of.A satellite digital television receiver set top box 1 can be used with a plurality of wireless receiving modules 3, the satellite digital TV program can be played back on the distinct device of different location like this.The form of traditional wired connection will realize the working method of a this satellite digital television receiver set top box to a plurality of playback equipments, will could realize that not only increased cost, numerous and diverse wiring has also destroyed the neat and artistic of room by numerous and diverse wiring usually.Adopt the form of wireless transmission of the present utility model just to avoid above-mentioned shortcoming fully.
Described satellite digital television receiver set top box 1 is that integral type is connected or detachable connection with down conversion module.
Described detachable connection is meant: the low noise down conversion module is provided with threaded F head, the rf inputs of the tuner of satellite digital television receiver set top box 1 is the F male of band nut, by being connected of threaded F head and the F male of being with nut, the low noise down conversion module is fixed on the radio satellite TV set-top box 1.
Satellite digital television receiver set top box and low noise down conversion module normally are connected respectively to satellite digital television receiver set top box and low noise block by an electric wire, this mode connects not too firm, and method of attachment of the present utility model not only is connected firmly and has also saved cable.Whether and it is dismountable for flexibly connecting, can look the development of low noise down conversion module on client's needs and the market and determine low noise down conversion module and satellite digital television receiver set top box 1 whole the sale.
Described wireless receiving module 3 is provided with the combination of a kind of or above-mentioned two or more interfaces in HDMI interface, VGA interface, DVI interface, Display-port interface, video component interface, the S terminal.Here be giving an example of docking port type, and be not limit, the utility model can connect various receiving equipment, for the modern life that high definition device is increasing has been brought facility.
Described wireless transmitter module 2 and wireless receiving module 3 are respectively to the WHDI wireless transmitter module and are the WHDI wireless receiving module.Described high-definition audio and video signal is that highest resolution is the high-definition audio and video signal of 1080p.The WHDI wireless sending module adopts the MIMO-OFDM technology, can transmission bandwidth reaches the high-definition audio and video data flow of 3Gbps, and transmission range reaches 30 meters, can carry out the transmission that highest resolution is the harmless audio and video information of 1080p.
Below in conjunction with Fig. 1 operation principle of the present utility model is described, low noise down conversion module receiving satellite word TV signal, after the tuning and demodulation of digital TV set-top box 1 via satellite, output high-definition digital video signal, the mode that wireless transmitter module 2 combines by MIMO technology and OFDM, the high-definition digital video signal is modulated to above the frequency band of 4.9-5.9GHz, then modulated signal is transmitted into the space.Simultaneously, wireless receiving module is demodulated into the high-definition audio and video signal with the modulated signal that receives, and plays by the playback equipment of receiving terminal again.
