Abstract
The utility model relates to a twelve-channel video modulator comprising an access video input end, a video control unit connected with the access video input end, a modulation unit connected with the video control unit, amplification circuits, distribution circuits, a wireless video output unit, and a wireless video receiving unit. The output end of the modulation unit is connected with twelve decoding units. The output end of each decoding unit is connected with a mixing circuit. Each mixing circuit is connected with a distribution circuit through an amplification circuit. The distribution circuits are connected with the wireless video output unit. The wireless video output unit is connected with the wireless video receiving unit through signals. By the twelve-channel video modulator, programs on twelve TV set can be watched simultaneously. Signals are transmitted wirelessly so that a trouble of wire laying is prevented. Therefore, cost is reduced and installing time is shortened.
Description
Technical field
The utility model relates to the field of electronic product, especially a kind of 12 road video modulators.
Background technology
Along with development of science and technology, the television transmission signal of a lot of countries begins by analog signal to digital signal transition, family's receiving digital signals needs special-purpose set-top box, the audio signal that could become television set directly to receive digital signal decoding like this, but, a lot of families all have two even multiple TV set more, and dispersed placement is in several rooms, every television set all needs have set-top box to decode, therefore these users just must buy many set-top box, increased the weight of burden, in addition, these have the user of multiple TV set if watch the program of DVD player, also can only be placed with again in the room of DVD player to watch, and not very convenient just sometimes.
At above-mentioned phenomenon, video modulator has appearred in the market, and this kind video modulator is by wire transmission, and it need spread line could realize the signal transmission, installs and assists, the use cost height.
Summary of the invention
The technical problems to be solved in the utility model is: in order to overcome the above-mentioned middle problem that exists, provide a kind of 12 road video modulators, its project organization is reasonable, easy to use, easy for installation.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of 12 road video modulators, comprise the access video inputs, the video control unit that is connected with the access video inputs, the modulating unit that is connected with video control unit, amplifying circuit, distributor circuit and wireless video output unit and wireless video receiving element, described modulating unit output is connected with 12 decoding units, each decoding unit output is connected with hybrid circuit, hybrid circuit is connected with distributor circuit by amplifying circuit, distributor circuit is connected with the wireless video output unit, and wireless video output unit and wireless video receiving element connect with signal.
In order in use to play the purpose of protection, described modulating unit also is connected with lightning-protection module and warning device.
The beneficial effects of the utility model are: described a kind of 12 road video modulators, adopt this kind modulator, and can realize that 12 television sets watch simultaneously, utilize wireless signal transmission, avoided the trouble of shop line, reduced cost, reduced the set-up time.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the overall structure block diagram of a kind of 12 road video modulators described in the utility model.
Accompanying drawing acceptance of the bid keep the score state as follows: 1, insert video inputs, 2, video control unit, 3, modulating unit, 4, amplifying circuit, 5, distributor circuit, 6, wireless video output unit, 7, wireless video receiving element, 8, decoding unit, 9, hybrid circuit, 10, lightning-protection module, 11, warning device.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of 12 road video modulators as shown in Figure 1, comprise and insert video inputs 1, the video control unit 2 that is connected with access video inputs 1, the modulating unit 3 that is connected with video control unit 2, amplifying circuit 4, distributor circuit 5 and wireless video output unit 6 and wireless video receiving element 7, modulating unit 3 outputs are connected with lightning-protection module 10 and warning device 11 with 12 decoding units 8 respectively, each decoding unit 8 output is connected with hybrid circuit 9, hybrid circuit 9 is connected with distributor circuit 5 by amplifying circuit 4, distributor circuit 5 is connected with wireless video output unit 6, and wireless video output unit 6 connects with signal with wireless video receiving element 7.
A kind of 12 road video modulators of the present utility model, using this video modulator to make, vision signal is by inserting video inputs 1 input, vision signal after the input is by video control unit 2 controls, utilize modulating unit to carry out modulation treatment, utilize decoding unit 8 to carry out signal decoding then, decoded signal mixes the back by hybrid circuit 9 and amplifies, and receives the signal of wireless video output unit 6 outputs at last by wireless video receiving element 7.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
