Description

Audience rating statistical system and statistical method thereof based on tuning frequency and station symbol coupling

Technical field

The present invention relates to a kind of audience rating statistical system and statistical method thereof, especially relate to a kind of by station symbol being carried out the way of image recognition, automatically obtain the corresponding relation between TV signal frequency and the TV station, and utilize this corresponding relation, carry out the audience rating statistical system and the statistical method thereof based on tuning frequency and station symbol coupling of audience rating statistical.

Background technology

The traditional TV station and the audience rating statistical of TV programme adopt diary method and personnel's measuring instrument method usually.Diary method is meant by filling in the method that the diary card is collected audience information by all 4 years old and above kinsfolk in the sample family.Each kinsfolk has diary card separately in the sample family, requires them situation about televiewing every day, comprises that the channel watched and time period etc. are recorded on the diary card of oneself at any time.The listed time interval is 15 minutes on the diary card.Each Zhang Riji card can write down the viewership in a week.Because the error of user memory cause the error of statistics, can not in real time carry out easily by the calculating of statistics simultaneously for the method.

Personnel's measuring instrument method is meant that utilization " personnel's measuring instrument " collects the method for television program receiving information, is audience investigation means commonly used in the world at present.Each member of sample households has the button of oneself on hand controller, but also leaves guest's button.When the member of family begins to see TV, must click the button of representative oneself on the hand controller earlier, when not seeing TV, click this button again, measuring instrument can be all information that teleview the time period to store with the per minute, is sent to the central computer of general headquarters then by telephone wire.In this scheme, data can be by Network Transmission to data center, and audience ratings is calculated comparatively rapid, but personnel's measuring instrument cost is higher.

At present, a kind of new product form, internet television have appearred in television set.This kind television set has increased mixed-media network modules mixed-media in television set inside on the basis of general television set function, make that TV can be by the broadband access the Internet, thereby realizes watching and use on the television set content and service from the Internet.Because this type of television set has the internet information return path, therefore, have an opportunity to watch the viewing-data of TV to collect automatically the user, and automatic returned data center, the automatic statistics of realization audience ratings.

As application number is that 200810305143.8 application for a patent for invention discloses a kind of television audience rating data collection method, this method is: in the time of start or replacing channel, the television set microprocessor obtains the tuned frequency of current in progress television channel from its internal storage, the modulation frequency and the current time of television channel are sent to the audience rating data receiving system as audience rating data, and the audience rating data receiving system reports to audience rating data processing center by network with audience rating data.There is following defective in this scheme:

1) in different areas, under different radio and TV operator's networks, be different to the employed modulating frequency of the channel of same TV station, and, areal, under the network of same operator, regular meeting changes during the employed frequency of same television station channel;

2) angle of using from reality is difficult in time collect and follow the tracks of the nationwide, several thousand big and small radio and TV operators, up to ten thousand frequency point information and the variations that channel is provided with.

Therefore, by frequency and the time point of only collecting, will be difficult to be converted into the viewership information that channel and time point are formed.
