A time shift reproduction time controlling method and an information
reproduction apparatus are disclosed wherein reproduction of data at time
which is beyond time shift reproduction possible time is prevented with
certainty. An input PCR extraction section extracts a PCR from a
reception transport stream and outputs the extracted PCR to a subtractor.
An output PCR extraction section extracts a PCR from a transport stream
read out from a recording medium and outputs the extracted PCR to the
subtractor. The subtractor subtracts time information from the output PCR
extraction section from time information from the input PCR extraction
section and outputs a result of the subtraction to a comparator. The
comparator compares the output of the subtractor and output of a
reproduction time control register in which a value indicating a time
limit to time shift reproduction is stored with each other and outputs a
result of the comparison to a reproduction stopping control section. The
reproduction stopping control section performs control for outputting a
transport stream outputted from a TS readout section to a video and audio
decoder in accordance with the comparison result of the comparator.
