Detailed description of the invention
In order to overcome the deficiency of existing multi-screen interactive, the present invention proposes a kind of data transmission method based on sound and system, make user when carrying out multi-screen interactive without individually buying a wifi equipment, and need not equipment room and set up the process connected, this multi-screen interactive is the multi-screen interactive in a kind of near field.Data or link are mainly encoded by it by cloud server, are encoded into one section of brief sound short code, then return again to source device, and this section of sound code is converted into the sound of corresponding different audio frequency and plays back by source device.It is decoded into sound short code after carrying out other this section of sound of equipment uppick of multi-screen interactive, and decodes this sound short code by cloud server, obtain the reference address information of data to be shared or content, thus complete a multi-screen interactive.
For making the purpose of the present invention, technical scheme and advantage clearer, clear and definite, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
See the flow chart that Fig. 1, Fig. 1 are the data transmission methods based on sound that the present invention provides, comprise the following steps:
Step S100, source device receive user and transmit the request of data, and dataacontent address is sent to cloud server, described cloud server described dataacontent address is encoded to a sound short code, and feeds back to described source device.
Wherein, it is source device that the equipment of data transfer request is initiated in the present embodiment definition, equipment for the purpose of the equipment of the data content obtaining request transmission, 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 needing transmission, then dataacontent address is sent to cloud server.This dataacontent address can be the network address of data content, it is also possible to be the path that stores in source device plus data content, the network address of source device.Therefore, when carrying out data transmission, each purpose equipment can obtain data content from source device, it is also possible to obtains data content from network.Therefore, the scope of data content has obtained significantly extending, the multiformity of the data transmission of enhancing.
Server is after receiving the dataacontent address that source device sends beyond the clouds, encodes this dataacontent address, dataacontent address is encoded to one group of code word, and we define this group code word is sound short code.For the coded system used, the present embodiment is not limited to any, for example, it is possible to dataacontent address is encoded to binary code word or decimal scale code word or hexadecimal code word or ASCII character etc..If dataacontent address is encoded to binary code word, such as dataacontent address is " 123.com ", then this dataacontent address can be encoded to " 00,000,001 00,000,002 00,000,003 00101110 by us
01100011 01,101,111 01101101 ", and if be encoded to decimal scale code word, then this dataacontent address is encoded to " 123
46 99 111 109”；If being encoded to hexadecimal code word, then this dataacontent address is encoded to " 01 02 03 2E 63
6F 6D”.Certainly also have other coded system, then this citing that differs.And cloud server is after being encoded to sound short code by dataacontent address, described sound short code is returned to source device.
Described sound short code is encoded to a sound clip by step S200, described source device, and outwards broadcasts described sound clip.
Wherein, after source device receives the sound short code that cloud server returns, this sound short code is encoded again, this sound short code is encoded to a sound clip.Specifically, source device, according to each code word in sound short code, is respectively the voice signal of each codeword matching different frequency, then these voice signals is synthesized a sound clip.
Such as, if cloud server uses binary coding, then " 0 " and " 1 " in sound short code can be represented by source device with the low and high level in voice signal, high level represents " 1 ", low level represents " 0 ", the code word of each 0 and 1 in sound short code is represented with the voice signal of low and high level respectively, these voice signals are synthesized a complete sound clip the most again.After sound clip synthesis, this sound clip is sent out away by source device with the form of broadcast.This coded system can be easy to be converted to sound short code sound clip, and in Near-field Data transmits, sound clip is prone to transmission, it is simple to identify, and voice transfer is easily achieved.
Step S300, purpose equipment receive and decode described sound clip, obtain described sound short code, and send described sound short code to cloud server, described cloud server therefrom parse described dataacontent address and feed back to described purpose equipment.
Wherein, after sound clip is broadcasted by source device, purpose equipment can be easy to obtain this sound clip, then this sound clip obtained is decoded processing by purpose equipment, this sound clip is decoded into above-mentioned sound short code, the code encoding/decoding mode of its purpose equipment and source device identical to the code encoding/decoding mode of sound short code.
Such as, purpose equipment receives the one section of voice signal represented with low and high level, then high level is converted to " 1 " by purpose equipment, is " 0 " by low transition, the most available one group of code word " 00000001 after having processed
00000002 00,000,003 00,101,110 01,100,011 01,101,111 01101101 ", the most above-mentioned sound short code.After purpose equipment obtains this sound short code, the transmission of this sound short code is resolved to cloud server, being parsed dataacontent address " 123.com " from this sound short code by cloud server, then this dataacontent address is returned to purpose equipment by cloud server
Step S400, described purpose equipment receive the dataacontent address that cloud server sends, and access described dataacontent address, obtain data content.
After purpose equipment receives this dataacontent address, i.e. can get data content by accessing this dataacontent address.Thus achieve the data transmission of source device and purpose equipment room.
Certainly, if data content is less, data content directly can be sent to cloud server and encode by the present invention, draw a sound short code, and be converted into a sound clip by source device and be sent to purpose equipment, this sound clip is being decoded by purpose equipment, obtain sound short code, and parsed data content by server and feed back to purpose equipment, so, for the data transmission that data content is less, purpose equipment can be saved and obtained the flow process of data content by dataacontent address, make source device more efficient with the transmission of the data of purpose equipment room.
The data content of the present invention can be picture, document, video, audio frequency etc..And the present invention uses cloud server that dataacontent address is carried out encoding and decoding primarily to reduce the process requirement of multi-screen interactive equipment, reduce equipment cost.
From said process it can be seen that the data transmission method of the present invention is not required to the support of wifi, it is not required that two equipment rooms set up communication connection.Therefore the transfer voice of the present invention is especially advantageous for the multi-screen interactive of many equipment rooms near field, and not only efficiency is high, and disturbs little.

, or be encoded to hexadecimal code word " 01 02 03 2E 63 01101111 01101101 "
6F 6D " etc..
This sound short code is returned to device A by step S104, cloud server；
Step S105, device A receive the sound short code that cloud server sends；
Step S106, device A, according to sound short code, send the sound of corresponding frequencies；When sending the sound of corresponding frequencies, first sound short code is processed by device A, for the voice signal of each different code assignment different frequencies, then these voice signals is synthesized one section of sound, and this section of sound transmission is gone out by device A again.
Such as, if cloud server uses binary coding that video address " 123.com " is encoded to " 0000001
00000002 00,000,003 00,101,110 01,100,011 01,101,111 01101101 "; then the code word of each 0 and 1 in sound short code can be represented by device A respectively with the voice signal of low and high level, the most again these voice signals are synthesized one section of complete sound.
Step S107, equipment B hear the sound that device A propagates from；
The sound heard is decoded by step S108, equipment B, obtains a sound short code；The cataloged procedure that sound short code is encoded to sound is mutually matched by equipment B by the decoding process of sound with device A, i.e. the code encoding/decoding mode of the two is identical.Such as, the voice signal that the low and high level form in sound represents is decoded as code word " 0,000,001 00,000,002 00,000,003 00101110 by equipment B
01100011 01101111 01101101”。
Sound short code is sent to cloud server by step S109, equipment B；
Step S110, cloud server receive the sound short code that equipment B sends；
Step S111, cloud server decode described sound short code, obtain video address；Decoding process in this step and the server reverse process to the cataloged procedure of video address in step S103.Such as, the sound short code " 0000001 that will obtain in step S108
00000002 00,000,003 00,101,110 01,100,011 01,101,111 01101101 " it is decoded as " 123.com ", that is to say video address.
Video address is returned to equipment B by step S112, cloud server；
