Television set is one of most important audio-visual amusement platform in present people's life, and its cardinal principle is by the tuner received television signal, after the audio frequency and video processing module is handled, plays on video screen and audio amplifier.In one family, in order to watch TV programme, normally all place television set in different rooms in different rooms, each television set is received television program independently.The shortcoming of doing like this is essential many TVs of buying, and has improved cost; And placing TV in each room takes up room excessive.

Chinese patent discloses a kind of television system No. 03803956.7, and its mother tv comprises: a plurality of tuners; Select the loop, it selects the received signal of mother tv projection usefulness from the received signal that receives by a plurality of tuners, the received signal that while chooser television projection is used; The 1st signal conditioning circuit, vision signal and audio signal that it carries out signal processing and generate mother tv projection usefulness the received signal of showing usefulness by the mother tv of selecting the loop to select; The 1st wireless transmission part, it will be wirelessly transmitted to electronic television by the received signal of selecting the electronic television projection usefulness that the loop selects; With the 1st control device, it is controlled a plurality of tuners, selects loop and the 1st wireless transmission part.Electronic television comprises: the 2nd wireless transmission part, and it is used to receive the received signal of the electronic television projection usefulness that sends from the 1st wireless transmission part of mother tv; The 2nd signal processing circuit, it carries out signal processing and generates vision signal and the audio signal that electronic television is shown usefulness the received signal that the electronic television that receives by the 2nd wireless transmission part is shown usefulness; With the 2nd control unit, it controls the 2nd wireless transmission part.

In the above-mentioned television system, the TV signal that a plurality of tuners on the mother tv are received is respectively applied for mother tv and electronic television broadcast, come down to all to be positioned over the tuner of two or more television systems on the mother tv, and electronic television is play from the TV signal of mother tv by the wireless mode reception, and the purpose of this television system is mainly to realize that the room that does not have the TV signal interface can pass through the electronic television TV reception.But on the structure of television system, there is the feature of the corresponding a plurality of players of a plurality of tuners equally in above-mentioned television system, and this point and many platform independent TV there is no essential distinction, can not reduce its cost.

The DPF product has developed a quite powerful stage, the function of DPF has been not merely to be used for browsing photo, a lot of DPF products have comprised as playing MP3, streaming media video and view text file etc., in addition the loading that also has wireless module be used for and mobile devices such as digital camera or computer between carry out the transmission of data and file.These function expansions make that DPF has obtained using more widely.

Nonetheless, people can not teleview by the DPF product at present, because the DPF product does not have the tuner of received television program signal.If can be with the sub-player of DPF product as existing television receiver, bring great convenience will for people's life, for example, use the television receiver TV reception in the parlor, in the bedroom, can watch TV programme, and needn't in the bedroom, purchase television set in addition by the DPF product from the parlor television receiver.Even may make DPF become a mobile TV terminal by giving the DPF load cell.

The utility model content

The utility model provides a kind of primary-secondary television, and its main purpose is to overcome the higher shortcoming of cost that has a plurality of tuners on the mother tv that has now in the primary-secondary television system and be directed at.

The utility model adopts following technical scheme: a kind of primary-secondary television comprises handset and machine tool; This machine tool comprises that television module, wireless audio and video transmitter module and control signal receive decoder module, and television module receives decoder module with wireless audio and video transmitter module, control signal and is connected respectively; This handset comprises DPF module, wireless audio and video receiver module, audio frequency and video processing module, control signal transmitter module and control module, wireless audio and video receiver module, audio frequency and video processing module are connected successively with the DPF module, and control signal transmitter module, control module are connected successively with the DPF module; The wireless audio and video receiver module of handset receives the audio-video signal from the wireless audio and video transmitter module of machine tool, and the control signal of machine tool receives the control signal of decoder module reception from the control signal transmitter module of handset.

Aforementioned a kind of primary-secondary television, the control module of its handset comprises remote control receiver module and remote controller, remote controller and remote control receiver module carry out wireless connections.

By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, whole primary-secondary television system only uses a tuner on the machine tool, and need not at a plurality of handsets a plurality of tuners to be set additionally, and utilize DPF of the prior art as handset, can make full use of existing resource, realize the primary-secondary television system with least cost; Two, also can TV reception by handset, exempt people need buy many television receivers could be in the worry of a plurality of rooms TV reception; Three, the remote control system of handset also may command machine tool switches/operation of channel searching or machine open/close, ON/OFF audio frequency and video outlet terminal, the remote control system of machine tool is the machine open/close operation of may command handset also, moves in different rooms and need not people, and is easy to use.
