Fig. 2 is a handset interior block diagram of the present utility model.
Fig. 3 is the general module interface schema that the utility model adopted.
Fig. 4 is an another kind of machine tool functional-block diagram of the present utility model.
Below in conjunction with drawings and Examples structure of the present utility model and operation principle and the course of work are elaborated:
Embodiment:
The utility model comprises two parts, 1) have the large scale TV of emission function, be referred to as machine tool; 2) have the small size TV of mobile receiving function, be referred to as handset.
Machine tool video screen is being play or the picture signal in it and audio signal after treatment, picture signal in it and audio signal are meant that the TV in the machine tool has signal but just not have picture signal and audio signal in the video screen broadcast, send plug-in wireless sending module to, or built-in radio transmitter, radio transmitter passes through transmitting antenna after this signal is modulated to a higher Frequency point (this Frequency point have several values available), launch wirelessly, the audio-video signal of described machine tool emission, it can be analog audio-video signal through ovennodulation, also can be the audio frequency and video digital signal through compressed encoding, the machine tool end has a plurality of switchable emission frequencies.Handset by receiving circuit and reception antenna with this signal next, through after the demodulation, signal is reduced into after the audio-video signal, generates rgb signal and audio signal by decoding circuit again, finally screen and the loudspeaker in handset reappear machine tool broadcast or image transmitted and sound.Handset can be the LCD TV of the small screen, can use powered battery, also can adopt the external power supply power supply.Be light flexible again.At removable playing audio/video---the fixedly in progress audio frequency and video of large scale TV synchronously display the play on the handset.Fixedly the TV end has a plurality of switchable emission frequencies.Can be by user's manual switchover, or automatic frequency-hopping.The removable playing audio/video of small size---handset adopts small size liquid crystal display screen or picture tube as display device, and built-in circuit has that wireless receiving, demodulation, video are separated, the voice playing function.Many the removable playing audio/videos of small size---handset can receive simultaneously and play same the audio-video signal that the large scale TV is launched.Described machine tool also can be band DVD fixedly TV that play and that be provided with radio transmitter and have the traditional tv function, so also can launch the content signal that machine tool DVD plays by radio transmitter, is received by handset and plays.
Example one:
As Fig. 1, Fig. 2, shown in Figure 3, example one adopts modular notion, the radio transmitter of radiating portion is integrated on the little module, this module is called wireless transmitter module, be prior art, by a general expansion interface, can adopt general module interface as shown in Figure 3, be connected to a large scale liquid crystal TV that has extendable functions and constitute machine tool.Provide the television audio and video signals that needs modulate emission by machine tool, and associated control signal, then it is transferred to the transmitter section in the module, by the transmitter modulate emission, come demodulate reception by handset at last again.Also can be by the action of manual frequency diverter switch control wireless control module.
One, the machine tool in the example: can be any TV that television audio and video signals output can be provided, in this example, employing be the large scale liquid crystal TV (27 cun, 32 cun, 37 cun and 40 cun) of our company's exploitation.
Described TV: this TV selects for use the PW118B+PW2300 of U.S. Pixelworks company as main scheme.
Wherein, 1) the PW118B major function is:
The interlacing of vision signal is changed line by line; The convergent-divergent control of digitized video; The figure image intensifying;
The core cpu of built-in x86 is as the master control IC control whole system of TV.
2) major function of PW2300 is:
The digital decoding of the vision signal of multiple standard; The analog-to-digital conversion of analog video signal; The output of composite video signal is provided.
In addition, in the TV of example 1, also adopted the processor of the MSP3410G of German Micronas company as audio signal, its major function is:
The beautiful tone signal of mediation of separating of television audio signals is decoded; Acoustic processing; The stereo output of left and right sides dual track is provided.
To sum up, be used for the audio-video signal of modulate emission, just come from Video Decoder PW2300 and audio decoder MSP3410G respectively, under the control signal effect of PW118B, be transferred to wireless transmitter module then.
In being connected of TV and wireless transmitter module, can adopt a kind of specifically defined general module interface, see shown in Figure 3ly, this interface definition is 44 cores, has wherein comprised audio-video signal, control signal, communication identification signal, infrared remote-controlled signal, power supply and ground wire.What use in this example is: the vision signal input; Stereosonic L channel input; Stereosonic R channel input; Wireless transmitter module Opportunity awaiting control for linear signal; Infrared remote-controlled signal; The module identification signal; Power supply; Ground wire.
Described wireless transmitter module then is made up of two following parts:
1) the wireless module T15T/D that provides of general sincere company mainly finishes the audio-video signal modulate emission of 4 passages, and it is operated in 2.4GHz, and bandwidth is 20M.And can be by the switching of 4 passages of outer control realization, frequency is respectively 2.410G, 2.430G, 2.450G, 2.470G.
2) the microcontroller ATTiny12 of Atmel company mainly finishes the decoding of infrared remote-controlled signal, and main frame is parsed by the control command that the infrared remote control form sends, and finally the passage by I/O mouth control wireless module T15T/D switches.
Two, handset: receiver section, comprise liquid crystal display screen and receiving circuit, what receiving circuit adopted is that the wireless module R10T that general sincere company provides is a wireless receiving module, after demodulating audio-video signal, video is sent into T100 and is carried out video decode, generate rgb signal and row field sync signal, send into 7 cun liquid crystal display screens and show.Audio signal is sent into sound accompaniment processing audio power amplifier and is handled amplification, finally drives loudspeaker and sounds.
By each part mentioned above, complete realization the product of panel TV composite aircraft.
Example two:
As Fig. 2, Fig. 3, shown in Figure 4, example two is a kind of changes to example one implementation method.For the product that does not need to provide modular functionality, or can not realize the TV of modular functionality.We have adopted the method formation machine tool that radio transmitter is integrated into television set inside, the preferred large scale liquid crystal TV of the utility model television set, comprising LCD TV audio frequency and video treatment circuit and microprocessor, can also be plasm TV, and radio transmitter as mentioned above; Be that with the difference of example one maximum the former wireless transmitter module that places the television set outside of machine tool is integrated into the inner formation of television set machine tool, has further simplified system, has omitted the general module interface.Other characteristic electron aspect is identical with example one as handset etc.
