Patent

CA 2138603

In a packet audio/video signal transmission system, program guide information is formed as a master guide (250) and a special guide (260). The master guide contains programming information for the period of the current several hours. The special guide contains programming information for the next thirty days, for example. The master guide is sent as a service on each carrier or transponder (210-230, 240) to render it readily available regardless of the carrier frequency to which the receiver is tuned. The special guide (260) is transmitted on only one of the carriers (transponders) to minimize use of system bandwidth.
