Abstract
In a transport packet stream separating apparatus, a packet identification filter extracts transport packets having a predetermined packet identification from a stream of transport packets. Each of the extracted transport packets includes at least one section. A section filter unit determines whether a header portion of each of the extracted transport packets is coincident with a reference data, and receives the section of each of the extracted transport packets to output regardless of coincidence or discrepancy between the header portion of each of the extracted transport packets and the reference data. Also, the section filter unit generates a reset signal when it is determined that the header portion of each of the extracted transport packets is not coincident with the reference data. An interface unit receives the section data from the section filter unit, and stores the received section in a storage unit while updating a write address from a start address. Also, the interface unit resets the write address to the start address in response to the reset signal.
