Referring to Fig. 1, Fig. 1 is the flow chart of the data transmission method based on sound provided by the invention, comprises the following steps:
Step S100, source device receive the request that user is transmitted data, and data content address is sent to cloud server, be a sound short code, and feed back to described source device by described cloud server by described data content geocoding.
Wherein, the equipment that data transfer request is initiated in the present embodiment definition is source device, the equipment that obtains the data content of request transmission is object equipment, when carrying out multi-screen interactive, first source device receives the transmission request of data that user sends, according to this transmission request of data, determine the data content that needs transmission, then data content address is sent to cloud server.This data content address can be the network address of data content, can be also that the network address of source device adds the path that data content is stored in source device.Therefore, when carrying out transfer of data, each object equipment can obtain data content from source device, also can from network, obtain data content.Therefore, the scope of data content has obtained significantly expansion, the diversity of the transfer of data of enhancing.
Server, after receiving the data content address of source device transmission, is encoded to this data content address beyond the clouds, by data content geocoding, is a group code word, and we define this group code word is sound short code.For the coded system adopting, the present embodiment is not limited to any, for example, can by data content geocoding, be binary code word or decimal system code word or hexadecimal code word or ASCII character etc.If be binary code word by data content geocoding, such as data content address is " 123.com ", we can be " 00,000,001 00,000,002 00,000,003 00,101,110 01,100,011 01,101,111 01101101 " by this data content geocoding, if and be encoded to decimal system code word, by this data content geocoding, be " 123 46 99 111 109 "; If be encoded to hexadecimal code word, by this data content geocoding, be " 01 02 03 2E 63 6F 6D ".Certainly also have other coded system, then this differs one for example.And cloud server is after being sound short code by data content geocoding, described sound short code is returned to source device.
Step S200, described source device are encoded to a sound clip by described sound short code, and outwards broadcast described sound clip.
Wherein, after the sound short code that source device reception cloud server returns, this sound short code is encoded again, this sound short code is encoded to a sound clip.Particularly, source device, according to each code word in sound short code, is respectively the voice signal of each codeword matching different frequency, then by the synthetic sound clip of these voice signals.
For example, if cloud server adopts binary coding, source device can represent " 0 " in sound short code and " 1 " with the low and high level in voice signal, high level represents " 1 ", low level represents " 0 ", each code word of 0 and 1 in sound short code is represented with the voice signal of low and high level respectively, and then these voice signals are synthesized to a complete sound clip.After sound clip is synthetic, by this sound clip, the form with broadcast outwards sends source device.This coded system can be easy to sound short code to be converted to sound clip, and in Near-field Data transmission, sound clip is easy to transmission, is convenient to identification, and voice transfer is easy to realize.
Step S300, the object equipment described sound clip that receives and decode, obtains described sound short code, and described sound short code is sent to cloud server, by described cloud server, is therefrom parsed described data content address and is fed back to described object equipment.
Wherein, after source device is broadcasted sound clip, object equipment can be easy to obtain this sound clip, then object equipment is to this sound clip obtaining processing of decoding, this sound clip is decoded into above-mentioned sound short code, and the code encoding/decoding mode of its object equipment is identical to the code encoding/decoding mode of sound short code with source device.
Such as, object equipment receives the one section of voice signal representing with low and high level, object equipment is converted to high level " 1 ", by low transition, be " 0 ", after finishing dealing with, just can obtain a group code word " 00,000,001 00,000,002 00,000,003 00,101,110 01,100,011 01,101,111 01101101 ", i.e. above-mentioned sound short code.Object equipment obtains after this sound short code, this sound short code is sent to cloud server resolves, by cloud server, from this sound short code, parsed data content address " 123.com ", then cloud server returns to object equipment by this data content address
Step S400, described object equipment receive the data content address that cloud server sends, and access described data content address, obtain data content.
Object equipment receives behind this data content address, by accessing this data content address, can obtain data content.So just realized the transfer of data of source device and object equipment room.
Certainly, if data content is less, the present invention can directly send to cloud server by data content and encode, draw a sound short code, and by source device, convert a sound clip to and send to object equipment, object equipment is being decoded to this sound clip, obtain sound short code, and by server parses, go out data content and feed back to object equipment, like this, for the less transfer of data of data content, can save object equipment by the flow process of data content address acquisition data content, make the transfer of data of source device and object equipment room more efficient.
Data content of the present invention can be picture, document, video, audio frequency etc.And the present invention adopts cloud server to carry out encoding and decoding to data content address, be mainly in order to reduce the processing requirements of multi-screen interactive equipment, reduce equipment cost.
From said process, can find out, data transmission method of the present invention does not need the support of wifi, does not need two equipment rooms to establish a communications link yet.Therefore transfer voice of the present invention is beneficial to the multi-screen interactive of many equipment rooms near field very much, and not only efficiency is high, and disturbs little.
