Abstract (en)
[origin: WO9217027A1] A method and apparatus for generating and collecting viewing statistics in a cable television system (100) is provided. A system manager (310) transmits one or more record times downstream to one or more remote terminals (120, 315a-315c) indicating a future point in time at which the terminal (120, 315a-315c) is to record the viewing statistics. The remote terminals (120, 315a-315c) store the one ore more record times in memory (503) and when the record time matches the current real time, the remote terminals (120, 315a-315c) store in memory (503) the viewing statistics. Thereafter, in response to a polling signal from the system manager (310), the set-top terminals (120, 315a-315c) transmit the previously recorded viewing statistics along with a time code corresponding to the time at which the viewing statistics were recorded upstream to the system manager (310), and the system manager (310) processes this information accordingly.
