TV program audience rating investigation method and system thereof

Abstract

The system includes a server and at least two terminal collection devices. Through Internet or GPRS device, the server transfers information including command of collecting images, discriminant function or weather forecast etc. to the terminal collection devices. Based on different commands received from the server, the terminal collection devices deliver different responses: transmitting image of TV program users watch for, sorts of TV programs users watch for, or information input from users to the server. Based on image information and information sorts of TV station sorts transferred back from terminal collection devices, the server calculates audience rating. Terminal collection devices collect signal from video output port of TV set. TV stations users watch for are realized through identifying station caption and carrying comparison of information of specific pixels picked from frames of TV images.
