Abstract
The invention relates to a television technology, in particular to a technology of television remote controller realizing the television function. The invention discloses a realization method of low-cost remote controller having television function and remote control system, which comprises the steps as follows: a. a received television signal is encoded by the television, and sent to remote controller; b. the received television signal is decoded by the remote controller; c. the decoded television signal is played by the remote controller. The invention also discloses the remote system. The mobile television function of the television is realized with low cost controller; the television is controled remotely by the remote controller in radio frequency mode; the invention has the advantages of non-directional and distant control operation to television for users.
Description
Technical field
The present invention relates to television technologies, particularly realizes the technology of TV functions on TV remote controller.
Background technology
Traditional television set is come out the current audio/video Signal Separation of channel of watching of user by the high-frequency tuning head, and audio frequency outputs to loud speaker after audio frequency amplifier amplifies; Video is then delivered to video processing part, handles the back and goes up demonstration at picture tube (or display screen).Remote controller can only send corresponding control code according to user's request as a control emitter.Along with people to the raising that quality of the life requires, watch TV programme whenever and wherever possible, the information of obtaining become a kind of very urgent demand.No matter any corner of user in environment for use is as long as hand takes remote controller just can easily watch TV programme.
Summary of the invention
Technical problem to be solved by this invention is that a kind of implementation method and remote control system that has the remote controller of TV functions cheaply is provided.
The technical scheme that the present invention solve the technical problem employing is, has the implementation method of the remote controller of TV functions, it is characterized in that, comprises the following steps:
A, television set are encoded to the TV signal that receives and are sent to remote controller;
B, the television signal decoder of remote controller to receiving;
TV signal behind c, the remote controller broadcast decoder.
Further, described step a comprises that also television set and remote controller carry out authentication, if by checking, then television set and remote controller exchange identity code;
Described step b is that remote controller is by the television signal decoder of identity code to receiving;
Further, described remote controller carries out remote control by RF-wise to television set.
Remote control system with TV functions, comprise television set, remote controller, it is characterized in that, described television set also comprises digital signal processing module and radio receiving transmitting module, described digital signal processing module links to each other with the audio frequency and video output of television set, and the audio-video signal after digital signal processing module will be encoded transmits to radio receiving transmitting module; Described remote controller also comprises digital signal processing module, radio receiving transmitting module, display screen, audio frequency output module, radio receiving transmitting module is connected with digital signal processing module, digital signal processing module is sent to display screen with decoded vision signal, and decoded audio signal is sent to the audio frequency output module;
Further, described radio receiving transmitting module is the wireless communication module of 2.4GHz;
Further, described remote controller also includes the infrared receiving/transmission port, and described infrared receiving/transmission port is connected with digital signal processing module;
Further, described audio frequency output module comprises audio conversion circuit and loud speaker, and digital signal processing module, audio conversion circuit, loud speaker are linked in sequence.
The invention has the beneficial effects as follows, realized the mobile TV capabilities of remote controller with lower cost, remote controller adopts RF-wise that television set is carried out remote control, and it is non-directional that the user is had the straighforward operation of television set, the remote advantage that moves.
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Description of drawings
Fig. 1 is a television set module map of the present invention.
Fig. 2 is remote controller module figure of the present invention.
Embodiment
In television set, install digital signal processing module additional, radio receiving transmitting module, as shown in Figure 1, the high-frequency tuning head is separated the audio/video signal (TV signal) of the current viewing channel of user, deliver to video a/d and audio A/D respectively, digital signal processing module carries out encoding process to the digital audio/video signal of conversion again, to reach the purpose of compressed video signals data volume, TV signal after will compressing again outputs to wireless receiving module, is launched by wireless receiving module.Digital signal processing module is also controlled high-frequency tuning head, video a/d and audio A/D simultaneously.
As shown in Figure 2, in remote controller, also add wireless receiving module, digital signal processing module, display screen, audio frequency D, A circuit and loud speaker, wireless receiving module is used to receive the TV signal behind the coding that television set sends, after digital signal processing module is decoded the TV signal of wireless receiving module input, respectively digital video is outputed to display screen, digital audio outputs to audio frequency D/A, audio frequency D/A delivers to loud speaker with the analogue audio frequency of conversion again, thereby makes remote controller have the ability of audio frequency and video reduction.Remote controller also is provided with the infrared receiving/transmission port, is used to realize remote controller to other remote controller, as the learning functionality of the remote controller of DVD, STB etc.Digital signal processing module by television set, the user can copy to the remote control mode of original remote controller in the remote controller of the present invention by the infrared receiving/transmission port fully, realize corresponding straighforward operation by the infrared receiving/transmission port, make its function of compatible original remote controller fully.Make television set like this when increasing new function, only need a remote controller just to be convenient to operation.
Wireless receiving module in above-mentioned television set and the remote controller is the double-direction radio communication module of 2.4G Hz.Remote controller by no transceiver module can not only TV reception beyond, and can launch user's control signal by the communication of 2.4G Hz, to realize the straighforward operation of user television set.And the communication of 2.4G Hz does not have spatial limitation, and the user needn't aim at television set could realize straighforward operation, has realized non-directional to TV remote-control and remote moving.
In order to protect the privacy of communicating by letter between television set and the remote controller, the present invention is when first the use, at first television set and remote controller carry out authentication by radio receiving transmitting module, if by checking, then television set and remote controller exchange identity code, then, television set is encoded to the TV signal that receives and is sent to remote controller; After remote controller receives TV signal, digital signal processing module is decoded to TV signal by the television set identity code that has obtained, and the digital video that decoding is come out outputs to display screen, digital audio outputs to audio frequency D/A carries out delivering to loud speaker after the digital-to-analogue conversion, realizes the ability of the TV functions of remote controller.
Remote controller and television set have formed one and have received one closed-loop system, break away from former remote controller and can only launch the restriction that can not receive, realized that by low cost TV remote controller watches the function of TV programme with oneself, and met user's use habit, product is succinct, easy-to-use.
