System.
By taking Spring Festival Party as an example, common typical scene has two kinds：A kind of is the user for watching on TV living broadcast of programs,
Another kind is the user relayed at the moment a little later in video website viewing.Meanwhile the user of these viewing Spring Festival Parties, it would be desirable to
Discussed for some specific program (singing, dancing, essay etc.) in party, rather than Spring Festival Party is discussed.See
See the user of relay, do not like yet program have it is acute in advance or participate in as live user the interaction of program thoroughly, such as and its
The user that he observes relay discusses together, participates in program hobby ballot etc..Based on above-mentioned scene, a kind of base provided by the invention
Referred in the video content recognition of dual-tone multifrequency and positioning and interaction systems shown in Fig. 8, its workflow includes following several portions
Point：
1st, program data generation workflow
Fig. 9 A are the workflow diagram that the present invention generates program data as the interactive service device of a citing.Refer to figure
9A, in this process, keeper set video frequency program title, video playback total duration and broadcast platform.If broadcast platform
It is uncertain, there is provided a general setting of acquiescence.Then server generates partial data according to double-tone multi-frequency coding allocation table.
Step 401- steps 404：, video frequency program is in server generation program name data, such as Spring Festival Party in 2015；
Need to set the total duration of program in advance simultaneously, for example set Spring Festival Party and broadcast total duration as 5 hours.This when services
Device identifies three essential informations：Programm name, actual program broadcast time (such as the 10th minute) and total program duration.Simultaneously
It can select to add additional information broadcast platform (such as CCTV, other TV stations, certain video website etc.).This four essential information lists
Member adds check code, constitutes the master data of 16 bit digitals.
| 1-3 positions | 4-6 positions | 7-12 positions | 13rd | 14-16 positions |
| Broadcast platform code | Program duration | Programm name | Check code | Current time |
Such as 16 master datas of generation are：6936983800013098
This data is divided into 5 parts, is respectively from left to right：
1-3 positions：Totally 3, corresponding 693, it is to broadcast platform code, by being distributed on server.
4-6 positions：Totally 3, corresponding 698, program total duration is represent, unit is minute, illustrates the total duration of this video
Position 698 minutes, submitted in advance in server by keeper.
7-12 positions：Totally 6, corresponding 380001, programm name code is represent, is distributed unitedly by server.
13rd：Totally 1, to should bar code 3, be check code, according to certain algorithm, calculated by above 12 bit digitals
And obtain.
14-16 positions：Totally 3, corresponding 098, program current time is represent, illustrates that video has played 98 minutes,
Distributed automatically by server.
Remarks：The equivalent international bar code general-purpose algorithm rule of check code algorithm.
Check code is calculated by above 12 bit digitals and obtained, detailed process is as follows according to certain algorithm：
S1：Take out the sum of the odd bits of the number, c1=6+3+9+3+0+0=21；
S2：Take out the sum of the even bit of the number, c2=9+6+8+8+0+1=32；
S3：By odd bits and be added with " even bit and three times ".
S4：Take out the units of result：117 (117%10=7)；
S5：This units is subtracted with 10：10-7=3；
S6：Units is taken (to remove remaining) 3%10=3 to 10 again to obtained number.
Step 405：Complete audio coding distribution.
Dual-tone multifrequency (DTMF) is the technical scheme developed by AT＆T Labs, is made up of high frequency group and low frequency group, two groups
Frequency respectively includes 4 frequencies, and a high-frequency signal and low frequency signal are superimposed to form a composite signal, can represent 1 numeral.
Dtmf signal can have 16 codings.Therefore the more traditional single-tone technology of dual-tone multifrequency technology is used, efficiency of transmission is higher, and the time is more
It is short, sound wave identification can be obviously improved in environmental noise accuracy rate and speed.In the present invention, acoustical range corresponding to this technology
In 17KHz~22KHz, the sound in the range of this, the mankind are difficult to discover, but mobile phone, TV, and the loudspeaker of computer etc. can be located
Reason.Table 1 illustrates double-tone multi-frequency coding mode.
Table 1, a kind of corresponding coding schedule of dual-tone multifrequency
| 19000 | 19300 | 19600 | 19900 | |
| 17000 | 1 | 2 | 3 | D |
| 17300 | 4 | 5 | 6 | E |
| 17600 | 7 | 8 | 9 | F |
| 17900 | A | B | C | 0 |
Such as 17000 and 19000 superposed signals in table 1, numeral 1 is represented.
Assuming that by taking table 1 as an example, it is also necessary to which voice signal addition origin identification in position is used for identifying one section of basic voice unit (VU).Such as
AD, i.e. 17900-19000 can be set, two superposition acoustic signals of 17000-19900 originate as unit data to be identified.This
Outside, we also set the encryption of 2 Bit Matrix Codings, and different digital represents behind can be with the corresponding coding schedule of dual-tone multifrequency.Such as table 2
It can also be encoded such as table 3.By the encryption to matrix coder, not only can effectively solve the capacity problem of 6 context identifiers,
And the safety issue of sonic transmissions can be lifted, effectively reduce the spoofed possibility of acoustic signal source.
Table 2, the corresponding coding schedule of another dual-tone multifrequency
| 19000 | 19300 | 19600 | 19900 | |
| 17000 | 0 | 1 | 2 | D |
| 17300 | 3 | 4 | 5 | E |
| 17600 | 6 | 7 | 8 | F |
| 17900 | A | B | C | 9 |
Step 406：Finally, complete data message is most of by seven, 20 bit digitals composition：
| 1-3 positions | 4-6 positions | 7-12 positions | 13rd | 14-16 positions | 17-18 positions | 19-20 positions |
| Broadcast platform code | Program duration | Programm name | Check code | Current time | Origin identification | Encode table code |
2nd, sound exports
Fig. 9 B are the workflow diagram that the present invention exports interactive acoustic signals as the interactive service device of a citing.It please join
Fig. 9 B are read, are comprised the following steps：
Step 407：In the server, partial data deposit sound coding data storehouse

Mesh combines broadcast.
Step 502：User equipment is acquired to broadcast sounds, gathers program audio sample.
Step 503：It is local in user equipment, audio sample is decoded, and preceding 13 bit digital is carried out according to rule
Correction.If correction failure, return to step 502, gathers audio sample in user equipment again.This process helps to be lifted
The preparatory and speed of audio identification, significantly reduce to the requirement of transmitted data on network amount.
Step 504：Based on successful data are corrected, complete program data is restored.
Step 505：Encrypt local data.
Step 506：By cipher mode, interactive request is initiated to server.
Step 507：Interaction request is identified server, recognition failures then return to step 506, identifies and successfully then enters
Step 508.
Step 508：Server actively pushes according to programme content identification code and actual program broadcast time to user equipment
Interaction content data.
Step 509：User on a user device, the interaction content provided according to service, participates in program interaction, for example chat
My god, ballot etc..
Step 510：User equipment again returns to user behavior data (user interaction data) database of server.
5th, the interactive flow of server and broadcast platform
Figure 11 is interaction diagrams of the present invention as the server and broadcast platform of a citing.Figure 11 is referred to, is wrapped
Include following steps：
Step 601：The interactive data that user leaves in user equipment (i.e. receiving device), returned data storehouse.
Step 602：Server carries out real-time data analysis to all customer data, produces data results.
Step 603：Server administrators can according to demand, self-defining data analysis method and result form.
Step 604：Server provides data external interface, can be used for other platforms (such as broadcasting platform).
