Abstract

The utility model relates to a television controlling device which can supply a plurality of persons for receiving programs with a plurality of channels simultaneously, comprising an electronic switch which can compress television signals with two or a plurality of channels into circulation according to the conventional sequence. The electronic switch is connected with viewing eyeglasses and earphones. The eyeglasses are synchronously instantaneous on-off liquid crystal eyeglasses controlled by the electronic switch. Acoustic frequency signals are uniformly enlarged or singly enlarged. Through the electronic switch, the acoustic frequency signals is output or singly output. Audiences wear the purpose-made eyeglasses and earphones. Through selecting, the audiences can see programs that the audiences want to see, whereas the utility model can not cause the situation that a plurality of persons contest channels.

Description

Can watch the control device of the tv of a plurality of channel programs simultaneously

The utility model is the improvement to television receiver, particularly can watch the control device of the tv of a plurality of channel programs for many people simultaneously.

Existing television set can only be watched the program of a channel at every turn, can not satisfy the requirement that two or more spectators watch the different channel TV programme simultaneously.

The utility model purpose provides a kind of control device of the tv, it is installed on the existing television set can be implemented in the TV programme of watching two or more channels simultaneously on the television set, to satisfy different spectators' rating requirement.

The TV images that we see usually is many points that television picture tube demonstrates at different time in fact, the impression that the visual persistence effect by the people forms.If the TV signal of a plurality of channels is become one tunnel sequential signal by certain frequency compression, example becomes the Signal Compression of channel 1, channel 2, channel 3 123 signals of arranging of rule, television set will be in certain sequence on same point, and (being 123 in this example) shows a plurality of channel informations, and will can't see image because of offering an explanation when detecting by an unaided eye, but utilize a finder that glimmers synchronously with compressed signal to cover unwanted signal, only expose the television image that at this moment signal that needs observation just can only see a channel.

According to above principle, the utility model project organization is:

A kind of control device of the tv that can watch a plurality of channel programs simultaneously is to have one the TV signal of two or more channels to be compressed into the electronic switch (1) of circulation in order, and this electronic switch (1) sees that with rule glasses (3) link to each other with earphone (4).And these glasses are the liquid crystal glasses of the synchronous instantaneous break-make of electronic switch (1) control.Watching the preceding selector switch (2) that is connected with of glasses (3) and earphone (4).Electronic switch is made of two or more unit, and each unit is made of a capacitor C, an inductance L, a field effect transistor T and a J-K flip flop, and each unit controls one road input signal.Need more input signal just to add plurality of units.

Utilize the utility model, with the TV signal of two or more channels, after the electronic switch compression, receive television set " video input " and locate, television set will show a plurality of TV programme.Audio frequency is amplified or amplifies separately through unified, and through electronic switch output or output separately, spectators put on special glasses and earphone, can see controlling oneself after selecting and want to have seen program.If in its television set of packing into, promptly constitute a new function TV, be a controller as independent assembling, directly be contained in the television video input port by the user, audio frequency is amplified in controller, just can use.

The utility model advantage is to satisfy the requirement that many people watch the different channel TV programme simultaneously, and very convenient with existing television set coupling.

Accompanying drawing 1 is the utility model schematic diagram.

Accompanying drawing 2 is the electronic switching circuit schematic diagram of the utility model three tunnel inputs.

Embodiment: electronic switch 1 linked to each other with signal source and receive the television video input port, observation glasses 3, the earphone 4 of liquid crystal flicker and receive electronic switch 1 output together after selector switch 2 links to each other and promptly constitute the utility model.Accompanying drawing 2 is the electronic switching circuit schematic diagram of three tunnel inputs, its total a, b, three unit of c, each unit has a capacitor c, an inductance L, a field effect transistor T and a J-K flip flop to constitute, each unit controls one road input signal, a, b, c are input signal among the figure, and i is an output signal, and glasses are controlled by Q, sound then by controlling Q or not controlling, can become one road signal with three road signals in this way and export in order.

Claims

1, a kind of control device of the tv that can watch a plurality of channel programs simultaneously, it is characterized in that: have one and the TV signal of two or more channels can be compressed into the electronic switch (1) of circulation in order, this electronic switch (1) links to each other with earphone (4) with watching glasses (3), and these glasses are the liquid crystal glasses of the synchronous instantaneous break-make of electronic switch (1) control.

2, control device of the tv according to claim 1 is characterized in that: watching the preceding selector switch (2) that is connected with of glasses (3) and earphone (4).

3, control device of the tv according to claim 1, it is characterized in that: described electronic switch (1) is made of two or more unit, each unit is made of a capacitor C, an inductance L, a field effect transistor T and a J-K flip flop, and each unit controls one road input signal.
