A recording system that is automatically triggered in response to the detection of a triggering event to record a desired signal. In order to determine whether the triggering event is present in the input signal, the recording system of the present invention detects whether a recognized pattern in the input signal corresponds to a reference pattern maintained in memory. Alternatively, the triggering event may be detected by performing a predetermined logic operation on those recognized patterns that match at least one of the reference patterns. The present invention also employs a buffer for delaying the input signal by a predetermined duration. Once the triggering event is detected, a recording device is activated to record the delayed signal for at least the predetermined duration. |
