    wherein the digital video inband transport stream does not contain SI data associated with and time multiplexed with the digital video data;

    receiving an out of band Asynchronous Transfer Mode (ATM) packet containing the digital video SI data, the ATM packet having a virtual channel indicator (VCI) in a header thereof associating the type of SI data in the ATM packet with a virtual channel;

    storing the SI information in a memory associated with the VCI; and

    retrieving the SI information from the memory associated with the VCI upon request of a system processor.
