Described receiver module 130 is installed on the television set, and is connected with the AV passage of television set, displays the play to receive video/audio signal that described sending module 120 sends and this video/audio signal is sent on the television set.Wherein, described receiver module 130 comprises the second Frequency Band Selection unit 131, rf receiver unit 132, demodulating unit 133 and filter unit 134; The described second Frequency Band Selection unit 131 corresponding described transmit frequency bands are selected suitable reception frequency range, so that described receiver module 130 can correctly receive the signal that described sending module 120 sends, and corresponding to the described first Frequency Band Selection unit, the described second Frequency Band Selection unit 131 also has four gears; Described rf receiver unit 132 receives the modulation signal that carries video/audio signal that described sending module 120 sends according to the described second Frequency Band Selection unit 131 selected reception frequency ranges; The described modulation signal that 133 pairs of described demodulating units receive carries out demodulation, so that described modulation signal is converted to the CVBS signal, thereby reduces video/audio signal in the described modulation signal; Video/audio signal after 134 pairs of demodulation of described filter unit carries out filtering, with the described video/audio signal of filtering issuable various clutters in transmission course, thereby exports stable video/audio signal to described television set.
Please refer to Fig. 2, Fig. 2 has showed the flow chart of the radio transmitting method embodiment that the present invention is based on iphone or ipod.As shown in Figure 2, described radio transmitting method based on iphone or ipod comprises the steps: step S101, and the decryption information of deciphering iphone or ipod video/audio signal is provided; Step S102 judges whether iphone or ipod are inserted on the connection base; Step S103 after judging that iphone or ipod are inserted on the connection base, obtains the video/audio signal after iphone or ipod decipher and sends described video/audio signal; Step S104 receives the video/audio signal of iphone or ipod and exports described video/audio signal to television set.
As shown from the above technical solution, the embodiment of the invention based on the radio transmitting method of iphone or ipod when described iphone or ipod are inserted into connect on the base after, can the video/audio signal in described iphone or the ipod be decrypted by described decryption information, make sending module can obtain and send the video/audio signal of described iphone or ipod, and receive this video/audio signal by receiver module, and on television set, display the play; Therefore the radio transmitting method that the present invention is based on iphone or ipod can be wirelessly transmitted to the video/audio signal of described iphone or ipod and show on the television set and broadcast, and is easy to operate simple.
Particularly, please combination is with reference to figure 3 again, and the embodiment of the invention of the present invention specifically comprises the steps: based on the radio transmitting method of iphone or ipod
Step S201 provides the decryption information of deciphering iphone or ipod video/audio signal; In this step, the video/audio signal of described iphone or ipod is decrypted,, sends and the reception operation thereby conveniently carry out follow-up signal so that described iphone or ipod can normally export the video/audio signal of himself by described decryption information is provided.
Step S202 judges whether iphone or ipod are inserted on the connection base; In this step, connect on the base by judging that described iphone or ipod are inserted into, but to determine whether the video/audio signal of described iphone of normal transmission or ipod.
Step S203 after judging that iphone or ipod are inserted on the connection base, reads described decryption information and sends described decryption information to iphone or ipod; In this step, described decryption information being sent to described iphone or ipod goes up so that described iphone or ipod can be decrypted the video/audio signal of himself.
Step S204, iphone or ipod receive described decryption information, and according to the described video/audio signal of described decryption information deciphering output; In this step, described iphone or ipod receive described decryption information, when the id information of received decryption information and iphone or ipod itself is not complementary, described iphone or ipod do not export video/audio signal, have only when the id information of received decryption information and described iphone or ipod itself mates, described iphone or ipod just export video/audio signal and send described video/audio signal for subsequent step.
Step S205 carries out frequency modulation(FM) to the described video/audio signal after the deciphering, and produces the modulation signal that carries described video/audio signal; In this step, by described video/audio signal being carried out frequency modulation(FM), send described video/audio signal thereby make things convenient for to carry out the conversion of signal mode.
Step S206 selects available transmit frequency band, and sends described modulation signal according to described transmit frequency band.In this step, by in available band limits, selecting the frequency range of the described modulation signal of emission, can prevent effectively that multiple signal from sending and issuable interference problem simultaneously.
Step S207, corresponding described transmit frequency band selective reception frequency range; In this step, corresponding described transmit frequency band is selected corresponding reception frequency range, to guarantee correctly to receive the modulation signal that carries described iphone or ipod video/audio signal.
Step S208 receives the modulation signal that carries described video/audio signal according to described reception frequency range.
Step S209, demodulation carries the modulation signal of described video/audio signal; In this step, by the described modulation signal of demodulation so that described modulation signal is converted to the CVBS signal, thereby reduce described video/audio signal.
Step S210 carries out filtering to the described video/audio signal after the demodulation, and exports filtered described video/audio signal to television set; In this step, the described video/audio signal of filtering is issuable various clutters in transmission course, display the play to export stable video/audio signal to television set, thereby make on the television set the shown image that plays back and sound clear bright and clear.
From the above, radio transmitting method based on iphone or ipod of the present invention by decryption information to determine whether to send video/audio signal, and after determining to send described audiovisual information, transmit frequency band and the selection that receives frequency range by transmitting terminal and receiving terminal, exactly the video/audio signal of described iphone or ipod is transferred to receiving terminal, realize described iphone or being wirelessly transmitted on the television set of ipod video/audio signal are displayed the play.
Above invention has been described in conjunction with most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
