APPARATUS FOR COLLECTING TV CHANNEL DATA AND MARKET RESEARCH DATA.

摘要

The data collecting apparatus is placed in each of number of monitor's houses to collect data such as TV audience rating and market research data and the monitored data thus collected are sent to a data centre through telephone circuits and are processed by a large computer to calculate desired data. The apparatus for collecting data comprises a channel detector for detecting the channel of a TV receiver that is being watched, a market research data input device, a personal data input device, and a data processing apparatus which stores and processes the data that are input. The detected channel data and a personal identification data are sent to the data processor via commercial power distribution lines. The market research data are input by using a bar code reader and a keyboard efficiently without any predetermined procedure. The personal data is input by using an input device which utilises infrared rays, and is easily identified by displaying a personal illustration.
