Description
Technical field the utility model belongs to television set and makes the field, relates to the improvement of TV set circuit and remote controller, is a kind of television set of transmitting television signals and the remote controller of received television signal specifically.
The existing double-menu television of background technology (picture in picture TV set), be that display screen with television set is divided into key frame and monitoring image two parts, monitoring image is that a jiao at video screen hews out a pocket and is used for showing channel program beyond the program of watching, this makes the user can be when watching a certain program, understand the situation of other channels, watch favorite program so that in time adjust channel.But this double-menu television also exists very important shortcoming: monitoring image has taken the part of display screen, has destroyed the integrality of key frame, and watches two programs simultaneously in same main interface, allows the people attend to one thing and lose sight of another, " misleading the public ".And double-menu television generally all can only send the sound of one of them picture, and another picture can only be watched image.And general remote controller has only the simple function of control television set, and itself can not receive television signals.Chinese patent discloses the utility model patent (patent No.: 92217641.8) of a kind of " the liquid crystal panel remote controller of used as television " by name, it is the liquid crystal micro television set to be housed constitute on existing TV remote controller, both circuit can be independently of one another, nothing electrically connects, also can both circuit be connected into one by selector switch, accordingly, the liquid crystal micro television set can be regulated control separately, also can regulate control by remote controller, its advantage is neither to destroy the integrality of host picture, can monitor other channel programs by the liquid crystal panel of remote controller again, and remote controller also can act on a liquid crystal micro television set and uses separately.Its major defect is to realize program memory and programing function, only can receive the radiovision program, and be difficult to the abundant cable television program of received content, thereby manipulate inconvenience.
The summary of the invention the purpose of this utility model is: the deficiency that exists at prior art provides a kind of television set of transmitting television signals and the remote controller of received television signal.Television set can send TV signal, antenna by remote controller receives and monitors other channel programs on the display interface of remote controller, television set and remote controller all have independently display interface, and all can receive audio-video signal, its circuit design is convenient to realize program memory, programing function by software.
The purpose of this utility model is achieved through the following technical solutions: a kind of television set of transmitting television signals, comprise: TV set circuit, it is characterized in that: the television audio and video signals output also links to each other with the input of a signal transmitter unit in the TV set circuit, and the output of signal transmitter unit links to each other with transmitting antenna.
Described signal transmitter unit is made up of modulation circuit and radiating circuit, and television audio and video signals is connected to the input of modulation circuit, and the output of modulation circuit is connected to the input of radiating circuit, and the output of radiating circuit connects transmitting antenna.
A kind of remote controller of received television signal, comprise housing, button, power supply of remote controller circuit, remote control coding circuit, reception antenna, radiating circuit, television circuit and display screen thereof, it is characterized in that having the CPU programmed circuit that to store the memory channel to be connected with the remote control coding circuit.
Independently receiver circuit is housed in the housing of the remote controller of described received television signal, and its operating key is arranged on the case panel of remote controller.
Broadcast receiver power circuit on the described remote controller is connected with the power supply of remote controller circuit.
Television circuit sound intermediate frequency amplifying circuit on the described remote controller also connects a head circuit.
The utility model compared with prior art has many advantages and good effect:
1, television set of the present utility model and existing television set contrast: by increasing the output and the transmitting antenna of signal transmitter unit, make remote controller of the present utility model can receive the TV programme of television transmission, display interface by remote controller monitors other channel programs, comprising cable television program, understand other channel at any time and perform in a radio or TV programme situation.Both all can be used as independently display interface, and all can receive audio-video signal, have increased sprite, can watch program separately.With the television set of normal tape picture-in-picture function relatively, main, sprite separates, and prevents from that picture is chaotic causedly to watch inconvenience, and synchronous sound playing is all arranged.
2, the TV remote controller of the utility model and other band liquid crystal displays relatively: general band liquid crystal display remote controller is independent product, realize that function needs the extra also assembly equipment of buying of user, not only inconvenience but also to increase cost more, and can only receive the radiovision program.The utility model is the combination of sending and receiving circuit, if the user bought with the television set of this kind equipment maybe this kind equipment just can directly use this function, needn't increase cost in addition and acquire equipment.Can not only realize program memory and programing function, but and the abundant radiovision program of received content, thereby, manipulate very convenient.
3, functions such as remote controller built-in radio set of the present utility model, head circuit, listening to audio broadcast for the user brings great convenience, satisfy the multiple needs of user.
