ABSTRACT:
A method of filtering a packet data stream as transmitted in a digital audiovisual transmission system characterized in that transport packet data is filtered at a first stage by a digital filter (42) according to the characteristics of the transport packet header, selected filtered data being then passed directly to a memory element (44) within the receiver/decoder. In a second aspect, the method comprises filtering a packet data stream characterized in that transport packet data is filtered at a first stage by a first digital filter (42) according to the characteristics of the transport packet header, selected filtered data from the payload corresponding to a continuous flux of data then being passed to a second digital filter (45) for a second stage of filtering.
