摘要:
A device with a packetising module (C1) including a sensing circuit (22) for sensing synchronisation words in the input stream; a storage unit (23) receiving a series of input stream bytes that have been presented to the sensing circuit (22); means (32) enabling transfer to a packet memory (PM1); and a processor (26) for determining the headers of packets put together from the input stream on the basis of the synchronisation words sensed by the sensing circuit (22), writing the headers into the packet memory (Pmi), and controlling the transfer means (32) so that the length of the header of one packet can be determined while the bytes of a previous packet are being transferred from the storage unit (23) to the packet memory (PM1).
