摘要： A system and method for controlling the transmission of signals within an interactive network which transmits audio/visual (A/V) information on at least one channel to a user and including a transmission source configured to transmit the A/V information on the at least one channel is provided. The system includes at least one set-top box and at least one random number generator. The set-top box is configured to record the A/V information on a channel at a predetermined recording time and to transmit a change channel request signal to the transmission source prior to the predetermined recording time to change the channel to record the A/V information at the predetermined recording time. The random number generator is configured to generate a time value such that the at least one set-top box transmits the change channel request signal to the transmission source at the time value prior to the predetermined recording time.
