Abstract
An integrated receiver with dual channel transport stream decoding and delivery substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides multiple time-base clocks for two transport streams. Transport processor circuitry uses multiple PCRs to track transport streams through decoding, storage and or delivery of the decoded signals for display. Provision of a multiple time-base clock for decoding and delivering multiple transport streams allows display of the two decoded audio-video signals on independent monitors.
