Abstract
Aspects of the present invention relate to methods and systems for controlling the distribution of supplementary content by generating a first control signal when known content is initially detected in a broadcast stream, and after generating the first control signal, generating a second control signal when the detected content is no longer detected in the broadcast stream. The first and second control signals may be used to control the distribution of supplementary content.
