ABSTRACT:
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.
