Abstract
A device for demultiplexing data encoded according to a MPEG standard in the form of a data flow including system and picture packets. The device includes means for independently organizing, according to the nature (system packet, video packet, audio packet, etc.) of the data included in the packets, the storing of the data in various registers, some of the registers being accessible in read mode by a RAM and other registers being accessible by a microprocessor.
Claims11
A device for demultiplexing data encoded, in the form of a data flow in system and picture packets, according to a MPEG standard, including a hardwired state machine which receives said data flow and searches for packet start codes for routing said packets, according to the content of said packet start codes, to various registers, some of the registers being accessible in read mode by a RAM and, some other registers being accessible in read mode by a microprocessor.
