Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Please with reference to Fig. 1, Fig. 1 is that the hardware circuit of the utility model embodiment connects sketch map.Should receive the device of the sub-program of relay television synchronously; Comprise TV and corresponding remote controller; It is characterized in that: said TV is provided with two tuners; Described tuner selects module to be connected with the TV governor circuit through television audio and video signals, and said television audio and video signals selects the output of module to be connected with a wireless transmitter module through the audio-video signal coding module; Described remote controller is provided with wireless receiving module, and described wireless receiving module receives this wireless transmitter module coding signal transmitted and play by the display screen and the loudspeaker of remote controller through decoder module.
In order to let those skilled in the art better understand the utility model; Below we combine Fig. 1 and Fig. 2 that each unit module of circuit is further specified; Among Fig. 1, TV partly comprises tuner 1 and tuner 2, television infrared module, TV governor circuit, television audio and video signals selected cell modular circuit, PIP audio-video signal coding module, audio-video signal transmitter module, tv display screen, TV power supply supply module.
Wherein, see two different cover TV programme for satisfying with the time, so adopt two tuners parallel connections to design.The tuner effect is meant radio television signal output complex tone vision signal after high-frequency tuner (including height, IF process integrated circuit) is handled.
Television infrared module: its effect can receive the remote control command input signal from remote controller output.
Tv display screen: can show and play TV programme (comprising the sub-program of PIP TV), be the first terminal display interface.
TV governor circuit: comprise function treatment such as CPU, demultiplexing processing, multichannel audio-video frequency decoding processing, the processing of audio frequency output control switching circuit, audio frequency DAC and power amplifier or the like.
Television audio and video signals selected cell modular circuit: be meant the multifunctional signal outlet selector, be equivalent to on-off action, can select a central signal of TV1 signal or TV2 signal as the PIP audio-video signal.
PIP audio-video signal coding module: when referring to that television audio and video signals selected cell modular circuit has been exported the TV2 signal and done the PIP signal, this module can be carried out encoding compression to the PIP signal and become numerical digit complex tone vision signal.
The audio-video signal transmitter module: the PIP signal that is meant coding OK is transferred to resume module packing and is transmitted into corresponding remote control receiver module through wireless technology again and handles.
TV power supply supply module: provide the energy to each module work of TV.
Band display screen remote controller comprises audio-video signal receiver module, remote control decoding module, remote control governor circuit, remote control display screen, remote keying instruction module, remote control transtation mission circuit, remote circuit supply module.
Audio-video signal receiver module: refer to the special transmitter module audio-video signal that receives from the TV end.
Remote control decoding module: refer to that being transferred to the remote control decoding module again by the audio-video signal that the remote control receiver module is handled carries out audio-video signal decoding decompression.
Remote control governor circuit: comprise remote control CPU, audio frequency and video switching controls, audio frequency and video processing, memory, wireless telecommunications etc.
The remote control display screen: can show and play the sub-program of PIP TV, be the second terminal display interface.
Remote keying instruction module: refer to the remote keying instruction that the user uses always, like channel key, sound key, number button, PIP key etc.The logical transition of this each key command input signal of module special disposal is calculated.When straighforward operation < PIP key >, television image is cut into PIP, when straighforward operation < PIP Out key >, can select one of which signal in the middle of TV1 or the TV2 signal as finally in the remote controller output of band display screen and play the sub-program of TV.Remote controller end broadcast program can be identical with TV end program, also can be different.
The remote control transtation mission circuit: the data message of special disposal button input instruction signal at last becomes light signal to be transmitted into the television infrared resume module in the middle of the TV by the instruction electrical signal conversion.
