Abstract
A method of processing a packetized datastream that includes program information and ancillary information used to acquire desired program information packets. The method includes the steps of identifying a first data unit that includes channel information and identifying a plurality of second data units included with the first data unit. The plurality of second data units are of a fixed length, and thus, separated in the packetized datastream by a multiple of a fixed offset. The method further includes the step of acquiring desired second data units using the fixed offset and subsequently determining the available services associated with a program and acquiring the desired program packets from the datastream.
