Abstract
A channel identifying rolling bar code, transmitted with a television broadcast signal, is displayed at a selected location on the receiving television screen. An apparatus is secured to the television set to view the rolling bar code to identify the channel being transmitted and process that information as necessary to detect the periods of time that different channels are received by the particular set. That information is stored in an internal memory for eventual use by a central processor.
