Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] figure 1 Among them, it is mainly composed of two parts: the user-end data acquisition system and the central-end data processing system. The user-end data acquisition system includes an audio acquisition module 1, a feature extraction module 2, a data encoding storage module 3, and a sending module 4. The audio acquisition module Module 1 collects the audio signal of TV AV terminal, and audio frequency collection module 1 is connected with feature extraction module 2, and feature extraction module 2 carries out feature extraction to audio signal, encodes and packs and sends to data encoding storage module 3, and data encoding storage module 3 again Regularly send data to the center-end data processing system through the sending module 4; the center-end data processing system includes a corresponding receiving module 5 and a data processing modul...

Abstract

The invention relates to an audience rating survey system and an audience rating information searching method based on audio frequency characteristics. The invention has the advantages of restraints free from districts and nations, dependence free from all coding standards, influence free from environmental noises, volume and frequency response changes, wide applicability and popularization property, and the like. In the structure of the rating survey system, a user side comprises an audio frequency acquisition module, a characteristic extraction module, a data storage module and a transmitting module; a data processing center comprises a receiving module and a general microcomputer or minicomputer processing module; wherein the audio frequency acquisition module is connected with an AV terminal of a television; acquired audio frequency signals are sent to the characteristic module for extracting appointed passband characteristics and carrying out energy unification processing; processed data is stored into the storage module through coding packing; and finally, the transmitting module uploads the recorded audio frequency characteristic data of an audience rating user channel periodically / regularly (such as at the beginning of each month) in a wired or wireless mode; and a data processing center terminal carries out a statistic processing on received audience rating information by adopting the audio frequency searching method provided by the invention.

Description

technical field [0001] The invention relates to an audio feature-based audience rating investigation system and an audience information retrieval method. Background technique [0002] At present, the role of audience rating survey has become increasingly prominent. It not only helps TV stations to better arrange advertisements, evaluate program topic selection and production effects, but also helps TV stations to plan and design more targeted programs, maximize benefits and efficiently Use the time and audio / video resources of the program to realize the information dissemination, economic benefits and viewing effects of TV stations, audiences and advertisers. In the past, the statistics method of audience rating has the disadvantages of dedicated channel information collection equipment, complicated coding standards, geographical restrictions, poor versatility of equipment in application and promotion, and limited statistical data. Contents of the invention [0003] The o...
