description A method of filtering a packet data stream as transmitted in an digital audiovisual transmission system characterised 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 characterised 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.
