An information processor for processing an information stream comprising input packets, said information processor comprising input means for receiving said information stream and for receiving an indication of the boundaries in said information stream for each of said input packets, classification means for classifying said input packets according to transitions in quantitative characteristics of two or more of said input packets, and parsing means responsive to said classification means for parsing said input packets into output packets and for generating an indication of the boundaries of said output packets, wherein each of said output packets comprises or represents one or more of said input packets. view more

An information processor according to claim 1 or 2 wherein said parsing means generates an output stream comprising input packets parsed by said parsing means and said indication of the boundaries of said input packets.

An information processing method for processing an information stream comprising input packets, said method comprising receiving said information stream and receiving an indication of the boundaries in said information strum for each of said input packets, classifying said input packets according to intrinsic characteristics of said input packets or transitions in quantitative characteristics of two or more of said input packets, and parsing said input packets into output packets in response to said classifying, and generating an indication of the boundaries of said output packets, wherein each of said output packets comprises or represents one or more of said input packets. view more

An information processing method according to claim 9 wherein said parsing generates an output stream comprising input packets parsed by said parsing and said indication of the boundaries of said input packets.

An information processing method for processing an information stream comprising input packets, said method comprising receiving said information stream and receiving an indication of the boundaries in said information stream for each of said input packets, wherein each of said input packets comprises or represents one or more previously parsed packets, said previously parsed packets having been parsed according to one or more intrinsic characteristics of said previously parsed packets, classifying said input packets according to intrinsic characteristics of said input packets, and parsing said input packets into output packets in response to said classifying and generating an indication of the boundaries of said output packets, wherein each output packet comprises or represents one or more of said input packets. view more

An information processing method according to claim 9 or 11 further comprising reiteratively classifying and parsing said output packets to generate further output packets comprising or representing one or more packets previously classified and parsed. view more
