发明名称 TELEVISION AUDIENCE DATA GATHERING
摘要 A method and apparatus of collecting data from a television audience comprising storing in a first memory demographic descriptions of expected viewers of a television receiver, receiving signals from a viewer control operated by a viewer, displaying one or more indicia on a television screen for viewing by the viewer, designated by the character of the signals received from the control, in confirmation of the particular signal received from the control, and storing a signal in a second memory for later access corresponding to at least one form of the designated signal character, which is related to the designation of at least one selected expected viewer as an active viewer. The television viewer may use his remote control at any time, when the flashing prompt is flashing, or when it is not flashing, to change channels. There is no channel lock nor is there an annoying on-screen prompt enquiring as to the identity of persons in the viewing audience.
