Abstract
The utility model provides a rating device of one set of antenna in many TVs of on -vehicle satellite receiver, includes satellite receiver, antenna, TV, and its characterized in that adopts one set of satellite receiving antenna, divides ware supply power isolation and signal distribution and receive the decoder with direct broadcast satellite system synthesis digit and is connected through the merit, and direct broadcast satellite system synthesis digit receipt decoder is connected with the TV set. The beneficial effects of the utility model are that: having adopted and having used one set of on -vehicle satellite antenna, the ware is divided to two (or a plurality of) merits, two (or many) satellite digital receivers, the method of two (or many) TVs, can be on the TV in different rooms different TV program of the live star of star 9B in the rating simultaneously, can greatly reduced equipment cost.
Description
Technical field
This utility model belongs to the satellite television rating technology of special-purpose vehicle in-car TV technology, the especially a set of antenna of multiple stage TV.
Background technology
Along with the transmitting of culminant star 9B live broadcasting satellite uses, China's domestic satellite rating is by C-band to Ku spectrum conversion, and satellite antenna planar dimension is substantially reduced (tens cm levels), and then makes Vehicular satellite television reception become a reality.
Time on special-purpose vehicle such as lodging vehicle use Vehicular satellite television program receiving, one, a room TV can normally be watched.But when having 2 bedrooms (or many rooms), having two TVs (or multiple stage TV) to see the demand of same TV when just having difference, if now using two set (or overlapping) satellite antenna modes, cost is the highest more.Therefore we have employed and have used a set of vehicle-mounted satellite antenna, two (or multiple) power splitters, two (or multiple stage) satellite digital receivers, the method of two (or multiple stage) TVs, can on the TV in different rooms the different TV programme of rating culminant star 9B live broadcasting satellite simultaneously, equipment cost can be greatly reduced.
Summary of the invention
The purpose of this utility model is precisely in order to overcome the defect that above-mentioned prior art exists and the watching device providing a kind of a set of vehicle-mounted satellite antenna at least one television set of connection.
The purpose of this utility model is achieved by the following technical solution.
A kind of watching device of the Vehicular satellite receiver a set of antenna of multiple stage TV, including DVB, antenna, TV, this utility model is characterised by, use a set of satellite earth antenna, being powered isolation by power splitter and signal distributes and is connected with direct satellite direct broadcast system integrated digital Rcv decoder, direct satellite direct broadcast system integrated digital Rcv decoder is connected with television set.
This utility model power splitter is set at least one mutual series winding and connects, and in addition to the first power splitter, every power splitter is respectively connected with a direct satellite direct broadcast system integrated digital Rcv decoder, and every direct satellite direct broadcast system integrated digital Rcv decoder connects a television set；First power splitter connects on and off switch and the second power splitter respectively.
This utility model uses a set of vehicle-mounted satellite antenna, one supply module, two (or multiple) power splitters, two (or multiple stage) satellite digital receivers, two (or multiple stage) TVs, the radiofrequency signal that DC power supply exports with satellite antenna is separated by first power splitter, and the radiofrequency signal of second (the 3rd ...) individual power splitter satellite antenna output separates to next stage.As shown in Figure 1, as shown in Figure 2, multiple stage television program receiving connection mode is as shown in Figure 3 for two television program receiving connection modes for one television program receiving connection mode.
The audio-video signal of one satellite digital receiver output exports the television for play corresponding to.Each satellite digital receiver can press one of user preferences tens programs that rating live broadcasting satellite sends respectively respectively, and each digital receiver is non-interference.
But it should be noted that the remote controller of satellite digital receiver can disturb in same room, by a remote controller key in the most same room, two digital receivers can respond action simultaneously.

Fig. 2 is two television structure schematic diagrams of this utility model；
Fig. 3 is this utility model multiple TV set structural representation.
Detailed description of the invention
As shown in Figure 1, a kind of watching device of the Vehicular satellite receiver a set of antenna of multiple stage TV, including DVB, antenna, TV, this utility model is characterised by, use a set of satellite earth antenna, being powered isolation by power splitter and signal distributes and is connected with direct satellite direct broadcast system integrated digital Rcv decoder, direct satellite direct broadcast system integrated digital Rcv decoder is connected with television set.
This utility model power splitter is set at least one mutual series winding and connects, and in addition to the first power splitter, every power splitter is respectively connected with a direct satellite direct broadcast system integrated digital Rcv decoder, and every direct satellite direct broadcast system integrated digital Rcv decoder connects a television set；First power splitter connects on and off switch and the second power splitter respectively.
Satellite antenna is powered simply supplying power for tuner to antenna by general satellite digital receiver by coaxial cable, and power is less.
And during Vehicular satellite reception, due to antenna bearingt, the adjustable plate aerial of pitching, the motor output power that orientation, pitching rotate is relatively big, satellite digital receiver is not necessarily provided that relatively high power.Therefore an additional direct current 12V power supply is needed.In order to prevent interfering with each other between power supply and signal, add two points of power splitter (hereinafter referred to as power splitter) and direct current 12V power supply, satellite digital receiver and the power supply of satellite antenna, high-frequency signal are isolated.
Concrete connection is that direct current 12V power supply accesses from the input of power splitter, and satellite antenna connects the outfan one of power splitter, and satellite digital receiver connects the outfan two of power splitter.
Two television reception connection modes are as shown in Figure 2.
Use a direct current 12V power supply, two power splitters, two satellite digital receivers, two television sets.
Concrete connection is that direct current 12V power supply accesses from the input of power splitter 1, satellite antenna connects the outfan one of power splitter 1, the outfan two of power splitter 1 connects the input of power splitter 2, and satellite digital receiver 1 connects the outfan one of power splitter 2, and satellite digital receiver 2 connects the outfan two of power splitter 2.
Three points of power splitters can certainly be used, three points of power splitter input termination direct current 12V power supplies, three points of power splitter output one termination satellite antennas, three points of power splitter output two termination satellite digital receivers 1, the method for three points of power splitter output three termination satellite digital receivers 2.
Multiple stage television reception connection mode is as shown in Figure 3.
Use a direct current 12V power supply, many power splitters, multiple stage satellite digital receiver, multiple TV set.
Concrete connection is that direct current 12V power supply accesses from the input of power splitter 1, satellite antenna connects the outfan one of power splitter 1, the outfan two of power splitter 1 connects the input of power splitter 2, satellite digital receiver 1 connects the outfan one of power splitter 2, the outfan two of power splitter 2 connects the input of power splitter 3, satellite digital receiver 2 connects the outfan one of power splitter 3, connects downwards.
Multiple stage television reception can also use many points of power splitters, such as the connection of six power splitters, eight power splitters etc..
