Step S13：Export the audio/video program after audio mixing.In this step, the audio/video program after audio mixing can be carried out
Then compressed encoding is propagated via the channel of pre-selection, such as cable TV network, Web TV network, closed-circuit television net
Network, public's medium TV network etc..It can also be output on storage medium after above-mentioned compressed encoding, such as DVD disc etc..
After continuing to illustrate that voice signal is propagated in air for via vision signal of the dissemination channel with audio below
The process of processing is received by the equipment of user local.As for the acoustic communication algorithm in air, some existing maturations can be used
Wireless communication technique, such as chirp spread spectrums, MFSK, PSK modulation are in conjunction with channel equalization, OFDM, CDMA.
Step S14：Playback equipment receives the audio/video program then played in step S13.Here playback equipment includes
The video playback apparatus containing loud speaker such as television set, personal computer, tablet computer.Voice signal is i.e. in sky after being played
It is propagated in gas channel, that is, the audio signal for being mixed with acoustic coding signal is propagated via air passage.Following step by
Audio signal reception equipment intelligent terminal such as personal computer, tablet computer, smart mobile phone with such as microphone is complete
At.That is locally there are above-mentioned playback equipment and receiving device both equipment in user.
Step S15：Receiving device receives the audio signal in audio/video program.
Step S16：Receiving device carries out analog/digital conversion to the audio signal of reception.
Step S17：Receiving device extracts audio signal according to the feature of pre-selection from the audio signal after analog/digital conversion.
This feature should select to form the feature of acoustic coding signal in step S11.
Step S18：Receiving device successively carries out demodulation processing and decoding, checking treatment to the audio signal of extraction.
Step S19：The digital information that decoding in receiving device output step S18 is handled.As previously mentioned, here
Digital information can be the brief introduction of the commodity, the network address of online shopping, price information of discount etc., so that user utilizes.
