Description
Technical field
The present invention relates to a kind of audience rating statistics system based on the many members of family and method.This System and method for belongs to digital television broadcasting field, also belongs to media information investigating system and method, relates to the automatic collection of user audience data, convergence, transmission, storage, statistical analysis and application etc.
Background technology
Audience ratings refers to that the number (or family's amount) of watching a certain program in a certain amount of time accounts for the percentage of televiewer's total number of persons (or family's amount).The audience ratings that wherein footpath calculates per capita is called individual audience ratings, is called a family audience ratings by the audience ratings of family calculation of diameter.
Method for statisticsing audience rating current both at home and abroad at present has three kinds: telephone questionnaire method, diary block-regulations and investigating instrument method.
Telephone questionnaire method is exactly directly make a telephone call in user family, and user is just at TV reception in inquiry.The viewing behavior of user can be interrupted, and user is reluctant active participate; Diary block-regulations is exactly that investigator provides in card to user family, and user fills according to the viewership of oneself, and user often takes to recall afterwards and fills in, and the possibility forgeing seen program is large; Investigating instrument method, is rely on rating personnel before and after rating, initiatively confirms observer identity by the mode of corresponding button, the situation that this " initiative " requires just inevitably to occur " forget by ".
These methods are all for the TV user in unidirectional broadcast network, therefore collect master data and there is a lot of problem.Such as, telephone questionnaire method investigation result is with obvious subjective colo(u)r; Method of filling in a form is because rely on the memory of spectators, so investigation result poor accuracy; The automatic writing-method of investigating instrument needs to install special equipment, and cost is high, and investigator must register one's residence and carries out Data Collection, and workload is large, efficiency is low.Above 3 kinds of method poor real, all need human and material resources and the financial resources of at substantial.
Under the overall background of China's " integration of three networks ", the utilization of " Set Top Box ", coming on stage with glittering appearance of " digital bidirectional cable TV ", traditional TV audience rating metering system and method for statisticsing audience rating can not adapt to the development of China.
Along with China's expanding economy, rating mode " diversification ", viewing behavior " Focus ", kinsfolk's viewed programs type difference is large, therefore one family (is positioned over parlor usually by having a large TV, all see) to having multiple stage TV or other-end (expands to each bedroom, the program that respective selection is liked oneself is seen) development, this change makes traditional changing in the audience rating statistical mode of " individual is unit " gradually in the audience rating statistical mode of " family is for unit ", the utilization of family's multimachine top box, also lay a good foundation for realizing " individual " audience rating statistical.
At present, at the tentative Set Top Box metering system in some areas, user is allowed initiatively to input personal information by remote controller, the individual important privacy informations such as such as name, sex, age, work, income, user worries that the privacy of individual is likely reluctant active participate by revealing, need to pay a large amount of informing and persuade cost, its advantage can be had a greatly reduced quality.Also have patent to propose, install camera at home, extract channel that user sees, programme information by graphical analysis, in family, privacy may be completely exposed.
, to add premised on wired network, when a certain market digital bidirectional cable TV does not all cover, iff this investigation method of employing, certain sample removing property can be there is in the metering system of top box of digital machine.When on a market network from non-networking spectators and deposit have concurrently, new and old different rating mode have concurrently time, how to monitor and analyze the viewing-data of different system, how to realize fusion and the unification of data, be also need inquire into and solution problem.
Summary of the invention
In order to solve the problem, the invention provides a kind of audience rating statistics system based on the many members of family and method, for the audience ratings real-time statistics in the many members of family " rating Focus " situation, not only can realize traditional " in units of family " and carry out audience rating statistical, " in units of the individual " that can also realize truly carries out audience rating statistical.
For the problem that domestic consumer's personal information input difficulty and privacy are easily revealed, take the method that fingerprint inputs and member Cookie combines, personal information typing is simple, and user participates in the initiative meeting obviously enhancing of audience rating investigating.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
System is made up of (see accompanying drawing 1) 5 modules: data acquisition module (101), family network management module (102), data transmission module (103), data analysis module (104), sector application module (105).Each intermodule is two-way communication.
System architecture and realization (see accompanying drawing 2): system is made up of five modules, corresponding five layers (data collection layer, family network management layer, data transfer layer, data analysis layer, sector application layer) of framework.Wherein data acquisition module adopts finger print remote controller and Set Top Box composition; Family network management module adopts multiple Set Top Box and miscellaneous equipment in intelligent home gateway management man; Transport module provides broadcasting and TV, movement, telecommunication interface; Data analysis module is become with the database servers group of two-node cluster hot backup by application server; Sector application module is made up of client or browser.
The key data of system flows to (see accompanying drawing 3): kinsfolk inputs finger print information by set-top box remote controller, the encoded Set Top Box that passes to stores, kinsfolk watch TV or zapping time, finger print information or cookie information (kinsfolk no input fingerprint time, acquiescence cookie information) and programme information (business or channel, program, program category, time started, end time) stored in Set Top Box Flash or E
2in PROM, when sending (cycle) arrive, this information (data) is sent to application server after home gateway converges, after application server is unpacked according to preset format, stored in database server, application server outputs to each client or browser after analyzing from database extraction corresponding data according to sector application needs.Audience ratings rating Information and the descending kinsfolk's TV EPG that reaches of program recommendation information (in conjunction with video server) show.
Personal information gathers
(1) fingerprint code collection
Set-top box remote controller increases fingerprint identification function (Fig. 4), kinsfolk's information adopts fingerprint input, carry out encode (Fingerprint_ID) according to finger print information, code length is divided into 8 and 32 binary codes, main employing 8 binary shorter code, are convenient to set-top box processes at present.32 codings are reserved, can meet 42.9 hundred million populations everyone yard, so that following coding mapping and system extension.Finger-print codes adopts infrared remote control to pass to data of set top box acquisition module.
Kinsfolk switches: kinsfolk inputs finger print information first, stored in memory, can produce a finger-print codes, the then corresponding one and same coding when the same family member presses fingerprint again.When different home member presses fingerprint, then there is kinsfolk to switch, corresponding to the finger-print codes of current home member, this scene mainly occurs in parlor, the whole family sees the situation of TV together, in most cases individual sees TV in oneself bedroom, and a fingerprint and a Set Top Box correspondence, the probability switched is less.
(2) generation of Cookie
For watching TV first or being reluctant to input the kinsfolk of fingerprint, by the concept of internet C ookie, audience rating statistics system based on the many members of family takes similar Cookie mechanism to store the viewing channel of kinsfolk, program, time started, end time information, in Set Top Box, adopt the form of " variable=value " to preserve kinsfolk's audience information, design parameter is as follows:
STB_Number: Set Top Box is numbered
Cookie_ID: when kinsfolk chooses certain program, self registering kinsfolk's numbering
Expires: the life span of packet
Service_ID: service identification or channel identication
Program_Number: program code
Program_Class: program category code
Start_Time: the initial time of watching certain program, form is " YY-MM-DD HH:MM:SS GMT "
End_Time: the termination time of watching certain program, form is " YY-MM-DD HH:MM:SS GMT "
Secure: authentication field
Viewed programs information extraction
Take Set Top Box as the digital television receiving rate investigating system of hardware platform, the collection of data is obtained by the parsing of PSI/SI service information list, and this partial data comprises Set Top Box code, channel (business) code, program code, program category, watches date, time started and end time.
For traditional tv, because a channel can only play a program in a period of time, namely TV programme is linearly unidirectional.As long as therefore gather watch channel, the time started, the end time, then contrast electric program guide, just can know the programme information watched.And for Digital Television, using multiplex technique, the channel of a physics provides the road transport stream comprising multi-channel program.Watch a certain road program wherein, also must extract the compressed package of this road program from this transport stream, and then decode.So how from numerous transport stream, while choosing a road program to play, extracting business (or claiming channel) code and program code is realize the problem that audience rating statistical needs to solve.
In Digital Television, all videos, audio frequency, word, picture etc. become data after digitized processing, pack, define the transmission package of regular length (188 bytes) according to the standard of MPEG-2, then these packets are carried out multiplexing, form transport stream (TS).The channel of the corresponding 8MHz bandwidth of the transport stream be usually made up of multiple program and service integration.In order in a transport stream, find the code stream of needs, identify different business, MPEG-2 special definition PSI (Program Specific Information), its effect carries a transport stream of multiple program from one correctly to find specific program.Because system exists multiple transport stream usually, in order to find out the business that oneself needs from multiple transport stream fast, the PSI of DVB to MPEG-2 expands, and the basis of PSI tetra-table adds nine tables, defines SI (Service Information).The Integrated Receive Decoder (IRD) of Set Top Box can extract the rendition list and broadcast parameter from transport stream.
For Digital Television program request, prolong for the business of broadcasting, be not single linear broadcast mode, Set Top Box adopts usually shows analytic construction EPG and searching programs simultaneously from pat table → pmt table → NIT table → SDT table → EIT.But according to the actual decoding process of SI standard and Set Top Box, be first ignore pat table, pmt table, directly construct EPG from NIT table.First shown by extracting directly NIT in the dominant frequency point transport stream that pre-sets in Set Top Box, all carrier informations are searched for according to the transmission system parameters that NIT shows to carry, resolve SDT table, EIT table again, construct basic EPG information, its process is: show → generate EPG from NIT table → SDT table → EIT.
When Set Top Box switches the channel of different frequency by EPG menu, according to SDT(Service Description Table) show the task identifier Service_id that provides and find PAT(Program Association Table) table, this table shows the PMT(Program Map Table of each program in transport stream) PID, therefrom find program code (Program_Number) and correspondence Program Map Table mark (Program_Map_PID); Find the pmt table of corresponding program according to Program Map Table mark, pmt table gives the PID of each code stream of composition program; The TS of required programs just can be found to wrap according to the PID of each code stream; Then in conjunction with CAT(Condition Access Table) CAT Conditional Access Table (PID=1), descrambling, decoding.
When adding BAT(Bouquet Association Table) when showing, this table provides the relevant information of program service group, gives the business list in the title of bouquet and each bouquet.Utilize this table can carry out browsing and selecting of related-program or a certain class program easily.Kinsfolk can retrieve required program channel according to program classification.In the case, first the transport stream corresponding to this business will be found, according to the transport stream identification symbol of correspondence given in BAT table, search the transport stream indications of transport stream identification coupling therewith in NIT (Network Information Table), then according to the parameter in descriptor (as frequency, modulation system etc.) demodulate this transport stream, i.e. tansport_stream_id → NIT (obtaining the demodulation parameter flowed), complete according to the service group identifier bouquet_id in BAT again: bouquet_id → service_id → pat table → pmt table → find the TS of required programs to wrap → CAT table → descrambling → decoding.If this business is not by scrambling, " CAT table → descrambling " process can be saved.Search in SDT according to service_id simultaneously, obtain relevant service information, EIT(Event Information Table can also be searched) Event Information Table, obtain pertinent events information, such as time started, duration, program category etc.
By above analysis, when kinsfolk's switching channels, TV reception, can resolve from transport stream and intercept out business (or channel) code (Service_id), program code (Program_number), program category, enclosing Set Top Box coding, watching time started, the end time of program.The main syntactic structure of audience rating statistical traffic descriptor is as follows:
Audence_Rating_Statistcs
{
Family_Gateway_ID // home gateway mark
STD_ID // Set Top Box numbering
Family_Member_ID // kinsfolk's mark, fingerprint code or Cookie mark
Service_ID // business or channel identication
Program_Number // program code
Start_Time // time started
End_Time // end time
CRC_Check //CRC check
For (I=1; I<N; I++) // add up audience ratings one by one by program
{
Fingerprint_Cookie_Associate () // finger print data associates with Cookie data
Audence_Rating_Statistcs () // statistics audience ratings
}
}
Data of set top box sends form
Native system have employed top box of digital machine that can be mutual with application server, do not need the active participate of spectators, just sent the packet of set form from trend application server by network every the set time, initial data packet format (as shown in S51 in Fig. 5) is: " kinsfolk's code+traffic ID or channel ID+ program ID+ program category code+time started+end time+check code ", Set Top Box send data format (in Fig. 5 S52) be: " set-top box identification+kinsfolk's code+traffic ID or channel ID+ program ID+ program category code+time started+end time+check code ".Wherein kinsfolk's code has 2 kinds of forms: a kind of kinsfolk's form being fingerprint and identifying, and a kind of is the data format identified with Cookie_ID.If in kinsfolk's mark first " 0 ", representative is fingerprint code, if " 1 ", representative is Cookie code.
The data format that home gateway sends
After home gateway receives data of set top box, increasing home gateway mark, is generally MAC Address or IP address, then through TCP/IP encapsulation, is sent to the application server being in public network.
Home gateway send data format (in Fig. 5 S53) be: " home gateway mark+kinsfolk code+traffic ID or channel ID+ program ID+ program category code+time started+end time+check code "
Network is selected
Can unrestricted choice according to application needs: the transmission of CHINA RFTCOM Co Ltd transmissions/mobile network transmission/communication network.
The command format of Set Top Box and application server communication
Communication protocol aspect, according to communication process, initiate and receive different tasks and need different command protocols and controlled, each protocol instructions has its clear and definite task in communication process.
Set top box side instruction mainly comprises: initiate to connect (TS01), pair time success (TS03), collection period configuration successful (TS05), send data (TS07), Set Top Box wakes confirmation (TS09) up;
The instruction of application server end mainly comprises: connect confirm (TS02), pair time instruction (TS04), collection period configuration-direct (TS06), response confirm (TS08), wake Set Top Box instruction (TS10) up.Application server also has a special instruction: initiative Set Top Box uploading data (fetch data instruction TS00).
Instruction odd number coding stands Top to Server, even numbered represents Server to Top, and TS is Set Top Box (Top) and application server (Server) acronym, represents my sky simultaneously and thinks (TS) company.
Set Top Box and application server interactive communication be as shown in Figure 6: Set Top Box initiatively initiates connection request TS01, and server replys TS02 responsively after receiving the request, represents successful connection; Then when server sends TS04 instruction notification Set Top Box pair, Set Top Box receives rear reply TS03, success during expression pair; Then server sends TS06 (carry collection period parameter, collection period requirement >=5s, being less than 5s user may in zapping), and Set Top Box replys TS05, represents collection period configuration successful; Set Top Box starts data acquisition subsequently, and after the cycle arrives, send TS07 instruction notification application server, start to transmit data, after Data Transfer Done, application server is replied TS08 confirmation command and received.
Server initiatively sends heartbeat instruction TS10 every the set time, wakes Set Top Box up, if receive Set Top Box to reply TS09, proves that STB working status is normal; If do not receive, then continuing to send TS10 and wake Set Top Box up, through repeatedly attempting, still confiscating TS09 or setting-up time arrives, then think that Set Top Box is closed or fault.If STB working status is normal, application server can also send TS00, requires that Set Top Box passes the data cached of nearest time period back.
Data prediction
After application server receives data, according to agreement form unpack resolve after, stored in database.
Audience ratings (audience rating) is analyzed
According to service needed, statistical analysis is carried out to image data, by fingerprint statistic, can add up by CooKie, also can associate statistics by fingerprint with Cookie, produce corresponding audience ratings seniority among brothers and sisters table.
Number/total number of persons × 100% of this program of audience ratings=watch
Data mining, audience rating statistical and program commending
Because kinsfolk's viewed programs type there are differences, such as father likes to see news controlling, and mother likes to see South Korean TV soaps, and little daughter likes to watch animated films.Therefore according to viewed programs type, the fingerprint code data of certain hour section (being defaulted as a week) can be associated with Cookie data, analyses and prediction go out the program that kinsfolk individual likes seeing, carry out program commending.
The medium and small daughter of such as family inputted a fingerprint, see cartoon, Set Top Box can record her audience information: fingerprint code, service identification, program code, program category, time started, end time, in one week subsequently, during viewed programs, (being generally cartoon) have forgotten and press fingerprint on a remote control, at this moment Cookie can record her audience information automatically: Cookie_ID, service identification, program code, program category, time started, end time, therefore be " cartoon " according to viewed programs type, we have reason to infer that all viewed programs types be the kinsfolk of " cartoon " are the medium and small daughters of family, because it is a small probability event that father and mother watch animated films, therefore can be that finger print data and the Cookie data of cartoon produces and associate by viewed programs type, then audience ratings is calculated, the television EPG display of medium and small daughter and the audience ratings seniority among brothers and sisters returning cartoon is got home.
Fig. 7 is data mining, association audience rating statistical, program commending flow process:
Step S71: kinsfolk starts after using Set Top Box or Set Top Box to reset first;
Step S72: first judge that kinsfolk inputs fingerprint? exactly receive fingerprint code for Set Top Box? if receive fingerprint code, go to step S73; Otherwise go to step S74;
Step S73: by finger print data form store (set-top box identification+fingerprint code+traffic ID or channel ID+ program ID+ program category code+time started+end time+check code);
Step S74: by Cookie data form store (set-top box identification+Cookie_ID+ traffic ID or channel ID+ program ID+ program category code+time started+end time+check code);
Step S75: data are transferred to application server and stored in after database server, application server judges that kinsfolk's viewed programs type is identical or close through home gateway? S76 is gone to step if identical or close; Otherwise, go to step S79 and terminate;
Step S76: finger print data and Cookie data are associated, replaces Cookie code (Cookie_ID) with fingerprint code (Fingerprint_ID);
Step S77: then calculate audience ratings according to Fingerprint_ID;
Step S78: the audience ratings ranking list exporting the type program;
Step S79: terminate.
Data fusion is carried out with non-networking user
System provides the data importing interface of non-networking user, can carry out data fusion in proportion, by weights, calculate the audience rating data of fusion:
Merge audience ratings=networking user's audience ratings × networking user's weights+non-networking user's audience ratings × non-networking user's weights
Sector application
Client and browser two kinds of application models are provided.For client mode, client and application server adopt Socket to communicate; For browser model, browser communicates with application server http protocol.Client comprises: TV station, advertiser, ad-agency, research firm, national news publish General Bureau of Radio, Film and Television etc.
