Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the structure of the DTV investigating system that the embodiment of the invention provides, and for the ease of explanation, only shows the relevant part of the embodiment of the invention.This DTV investigating system comprises: digital TV front-end system 11, STB terminal 12, audience investigation instrument 13, investigation and analysis server 14.
In embodiments of the present invention, digital TV front-end system 11 sends questionnaires and gives STB terminal 12, after STB terminal 12 receives the questionnaire that said digital TV front-end system 11 sends; Be shown to the user; The user reads questionnaire, and fill out answers is in the test paper page of STB terminal 12 correspondences, after the user fills in and finishes; The coding code value of the answer of each exercise question is given audience investigation instrument 13 in the questionnaire numbering of STB terminal 12 transmission questionnaires and the questionnaire; Investigation and analysis server 14 receive and the said code value of store storage in audience investigation instrument 13 after, decode and obtain survey results information, can realize different types of investigation.
Because domestic all digital TV front-end systems all possess mail function at present; And the corresponding numbered television set intelligently card of each STB terminal; This digital television intelligent card has the unique ID number sign indicating number; Digital TV front-end system 11 can send mail according to this ID number and give specific user or customer group like this, and as one embodiment of the present of invention, digital TV front-end system 11 sends questionnaire through the form of mail and gives STB terminal 12.
STB terminal 12 receives the questionnaire that digital TV front-end system 11 sends; Be shown to the user, read questionnaire the user, fill out answers in the corresponding test paper page of STB terminal after; The answer of each exercise question in the questionnaire numbering of extraction questionnaire and the questionnaire from this test paper page; It is encoded, generate code value, send this code value through serial ports and give audience investigation instrument 13.
Audience investigation instrument 13, receive and the questionnaire numbering of storage STB terminal 12 through the questionnaire of serial ports transmission and questionnaire in each exercise question answer the coding code value and store.
Investigation and analysis server 14, the coding code value of the answer of each exercise question is decoded in the questionnaire numbering of reception questionnaire and the questionnaire, obtains survey results information.
All include different types of questionnaire in the wherein predeterminable some investigation of questionnaire batch, each investigation batch, the questionnaire of each kind can be made the multiple-choice question form, if problem is many, can questionnaire be numbered, and makes many parts of questionnaires.
Fig. 2 shows the realization flow of the digital television investigation method that the embodiment of the invention provides, and details are as follows:
In step S201, the digital TV front-end system sends questionnaire and gives STB terminal.
At present; Domestic all digital TV front-end systems all possess mail function; And the corresponding numbered television set intelligently card of each STB terminal; This digital television intelligent card has the unique ID number sign indicating number, and the digital TV front-end system can send mail according to this ID number and give specific user or customer group like this.
As one embodiment of the present of invention; All include different types of questionnaire in the predeterminable some investigation of questionnaire batch, each investigation batch, the questionnaire of each kind can be made the multiple-choice question form; If problem is many; Can questionnaire be numbered, make many parts of questionnaires, send to investigated STB terminal user with mail by the digital TV front-end system.Wherein, the kind of said questionnaire can relate to investigation to the digital TV front-end system service, advertising research, product investigation, market survey etc.
In step S202; After STB terminal receives the questionnaire of digital TV front-end system transmission; Be shown to the user; The user reads and fills in questionnaire, and the questionnaire numbering of filling in questionnaire, the answer that exercise question is numbered and each exercise question is corresponding are stored in the corresponding test paper page of STB terminal.
As one embodiment of the present of invention; STB terminal is shown to the STB terminal user after receiving the questionnaire of digital TV front-end system transmission, and the user chooses the exercise question in the questionnaire; From alternative answer, select the answer of corresponding exercise question; The questionnaire numbering of this questionnaire, exercise question numbering and the pairing answer of each exercise question are stored in the corresponding test paper page of STB terminal, and the concrete page is as shown in Figure 3.Wherein the alternative answer of exercise question can be shown to the user with the form of drop-down menu, also can be shown to the user with the form of OptionButton.
In step S203, STB terminal extracts test paper information and encodes from the corresponding test paper page of STB terminal, generate code value.
As one embodiment of the present of invention; After the user has filled in questionnaire; Click " completions " button among Fig. 3, confirm that test paper finishes, STB terminal receives the user and answers the questions in a test paper after the affirmation information that finishes; From the corresponding test paper page of STB terminal, extract the questionnaire numbering of the questionnaire that the user filled in and the answer of each exercise question and encode, generate code value.
In step S204, STB terminal sends code value through serial ports and gives the audience investigation instrument, and the audience investigation instrument receives and store said code value.
In step S205, send the code value that is stored in the audience investigation instrument through IP network and give the investigation and analysis server.
In step S206, the investigation and analysis server receives and is stored in the code value in the audience investigation instrument, and decoding, obtains investigation result.
Fig. 4 shows the structure of the STB terminal that the embodiment of the invention provides, and for the ease of explanation, only shows the relevant part of the embodiment of the invention.This STB terminal has investigation apparatus 41, and investigation apparatus 41 can be to be built in the unit that software unit, hardware cell or software and hardware in the STB terminal combine.
The questionnaire that questionnaire receiving element 42 receiving digital television front end systems send.Its detailed process repeats no more at this as stated.
Questionnaire information process unit 43 shows that the questionnaire that receives is to the user; The user reads questionnaire; After the fill out answers; The questionnaire numbering of STB terminal storage questionnaire, exercise question numbering and the pairing answer of each exercise question and to being stored in questionnaire numbering and the answer coding of each exercise question in the test paper page, generate code value in the corresponding test paper page of STB terminal.Its detailed process repeats no more at this as stated.
Investigation result transmitting element 44 sends the code value of questionnaire information process unit 43 generations and gives the audience investigation instrument through serial ports.Its detailed process repeats no more at this as stated.
