Abstract
A circuit and method for demultiplexing in a receiver a digital data stream including at least two types of data. In one particular application, such a receiver is used in a television system having a digital set-top-box receiver. A first control circuit extracts a packet identifier from an input data packet in the digital data stream, and generates a signal in dependence on whether the input data packet is of the first or second type. Sets of information associated with the first types of data packets and required by the receiver are stored in a memory under the control of a second control circuit. A third control circuit, responsive to receipt of the first type of input data packet, determines whether at least part of the input data packet matches the stored sets of information, and sets a match signal responsive thereto.
