Apparatus for recording and reproducing packetized data containing selectively recorded identification data

摘要

A data packet recording apparatus according to a first aspect of the present invention is comprised of: a trick play packet generator for generating trick play data by extracting one or plural types of prescribed date packets from an input data packet train comprising plural types of time-division multiplexed data in a prescribed number or packets based on an identification signal inserted for every packet and outputting a trick play data packet train by packetizing the generated trick play data; an identification table packet inserter for separating and retaining an identification table packet contained in the input data packet train for discriminating the identification signal and outputting the identification table packet into the trick play data packet train several times; and a recording circuit which is capable of recording the output of the identification table packet inserting means in trick play data recording areas at specified track positions.
