Abstract: In a data communication network wherein broadcasted transmissions include a portion uniquely identifying the content of the following transmission and wherein transmissions are repeated at predetermined intervals, a communication unit for operating within the system includes a receiver, a processor, and memory for storing data and instructions for the processor. The receiver receives transmissions over the communication network. The communication unit receives a record command from a user that causes it to record the audio/video content being broadcasted during a subsequent transmission thereof. The memory includes space for storing the program that causes the communication unit to automatically record the transmission at the time the transmission is re-broadcasted.
