Abstract
The invention discloses an information interaction technology for a media and a mobile device, and relates to the technical field of information. The technology comprises the following implementation steps: (1) terminal implementation, namely, (11) acquiring surrounding sound wave through Mic and converting analog signals into digital signals to be stored; (12) performing fourier transformation for the acquired sound wave; (13) extracting the maximum frequency at every 100 to 300ms and monitoring, decoding and then informing the internal of APP by call-back and other manners; (2) sound source, namely, (21) enabling phone side to face phone side, processing digital signal frequency by the sending side according to the fixed coding algorithm, and playing through a system loudspeaker; (22) mixing and inserting the generated high-frequency sound into an audio/ video file to be played. With the adoption of the technology, the existing sound wave information load can be increased, the problem of simple sound wave communication content is solved, the sound wave application field is expanded, and the sound wave coding standard is created.
Description
Technical field
What the present invention relates to is areas of information technology, is specifically related to the exchange technology between a kind of media and mobile device.
Background technology
Between current traditional media and mobile device neither one stablize, safety interactive mode.Traditional media content and mobile device are separated from each other, and traditional media and mobile device lack links up bridge.Acoustic current wave communication should use widely in iphone and android, the chirp in such as iphone, and the eggplant in android passes soon, and the sound wave of Alipay pays, and millet passes soon.These transmission technologys are all use sound wave as handshake mostly, then use wifi or other channel transmission datas.Such as eggplant passes possible being embodied as soon, recipient first sets up wifi hotspot, then hotspot name is sent by sound wave, and transmit leg decodes wifi hotspot title after receiving sound wave, then AutoLink focus transfer files, whole process does not need manual intervention.The core technology of these programs and difficult point are the acoustic communication of first stage.And our invention solves the Communication between traditional media and mobile device just.
Summary of the invention
For the deficiency that prior art exists, the present invention seeks to be to provide the exchange technology between a kind of media and mobile device, solve that existing sound wave actualizing technology information loads amount is little, acoustic communication content Single-issue, expansion applications of sound waves field be less; , coding criterion that sound wave is ununified problem.
To achieve these goals, the present invention realizes by the following technical solutions: the exchange technology between a kind of media and mobile device, and implementation step is: 1, terminal realizes:
(11), by Mic gather sound wave around, analog signal is converted to digital signal and carry out specimens preserving;
(12), Fourier transform is carried out to the sound wave collected;
(13), extract highest frequency in every 100-300ms and monitor, if meet induced signal frequency, then start to mate follow-up signal;
(14) if follow-up signal collection is right value, then this group signal response success, if fail in 10s, the match is successful, then abandon this coupling;
(15), notify that APP is inner by modes such as readjustments after decoding.
2, sound source portion
(21), mobile phone terminal to mobile phone terminal, transmitting terminal one side process digital signal frequency according to regular coding algorithm, and then calling system loud speaker is play;
(22), by generated high-frequency sound mixed insertion to sound (depending on) play in the middle of frequency file.
Beneficial effect of the present invention:
1, existing information of acoustic wave load capacity is improved;
2, acoustic communication content Single-issue is enriched;
3, applications of sound waves field question is expanded;
4, acoustic coded specification is created.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
This embodiment is by the following technical solutions: the exchange technology between a kind of media and mobile device, and implementation step is: 1, terminal realizes:
(11), by Mic gather sound wave around, analog signal is converted to digital signal and carry out specimens preserving;
(12), Fourier transform is carried out to the sound wave collected;
(13), extract highest frequency in every 100-300ms and monitor, if meet induced signal frequency, then start to mate follow-up signal;
(14) if follow-up signal collection is right value, then this group signal response success, if fail in 10s, the match is successful, then abandon this coupling;
(15), notify that APP is inner by modes such as readjustments after decoding.
2, sound source portion
(21), mobile phone terminal to mobile phone terminal, transmitting terminal one side according to regular coding algorithm to digital signal
Frequency processes, and then calling system loud speaker is play;
(22), by generated high-frequency sound mixed insertion to sound (depending on) play in the middle of frequency file.
The principle of the acoustic communication of this embodiment: mainly encode with unifrequency voice signal logarithm, then play these unifrequency sound, recipient, after receiving sound, identifies frequency, then decodes data according to frequency.Such as: we can by the corresponding numeral 3 of sine wave of the corresponding numeral of sine wave 2, the 1700HZ of the corresponding numeral of the sine wave of 1500HZ 1,1600HZ.So numeric string 3123 just corresponding 4 sections of sine waves, specify that every section of sine wave continues 100ms, then the acoustic segment of 3123 correspondence 400 milliseconds.Recipient's recorded voice, resolves the sound received, identifies 1700HZ, and 1500HZ, 1600HZ, 1700HZ tetra-sections of sine wave freuqencies, then search code book, the numeral decoded is exactly 3123.
This embodiment improves existing information of acoustic wave load capacity; Enrich acoustic communication content Single-issue; Expansion applications of sound waves field question; Create acoustic coded specification.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
