Use-related billing for pay TV

摘要

Technique for billing viewers for use of pay TV based on duration of viewing rather than a flat fee. A code signal is broadcast together with a programming signal. The encoded programming signal is received while a viewer is tuned to a selected program and decoded to derive a code therefrom which is used for determining a duration of time during which the viewer was tuned to that program. The thusly determined duration of time is combined with a designated billing rate to derive a use-based billed amount.
