发明名称 TELEVISION AND MARKET RESEARCH DATA COLLECTION SYSTEM AND METHOD
摘要 <p>TELEVISION AND MARKET RESEARCH DATA COLLECTION SYSTEM AND METHOD A remote data collection unit is provided at each of a plurality of panelist locations. The remote unit is adapted to be coupled to one or more television receivers or cable television converters. The data collection unit monitors and stores information as to what TV mode is in use, identification of the TV viewing audience and events such as channel changes and the like. The data collection unit further includes means for optically scanning bar codes and the like and storing that information, which can be representative of product purchase information or panelist responses to market research surveys. Substitute programming information may be supplied to selected panelist locations, as by transmission over an otherwise unused channel in a cable system along with control information. Information stored in data collection unit is periodically collected, either by interrogation of the data collection unit by a central computer, or by manual transfer of information to a portable data collector.</p>
