Patent ID: 8630530

Claim:
A time shift reproduction time controlling method for digital broadcasting for controlling a time limit in a case wherein reception data of digital broadcasting which includes time information is temporarily stored into recording means and the data recorded in the recording means is read out to perform time shift reproduction of information based on the recorded data, comprising the steps of: extracting, when time shift reproduction of information based on the recorded data recorded in the recording means is to be performed, the time information included in the recorded data; calculating a difference between time indicated by the extracted time information and time indicated by the time information included in the reception data currently received; and permitting the time shift reproduction of the information if the calculated difference is within the time limit determined in advance; but inhibiting the time shift reproduction if the difference exceeds the time limit, wherein the reception data is encoded data, and information used for reproduction of a decoding clock signal utilized to decode the encoded data is used as the time information included in the reception data and the recorded data; and information used for reproduction of a decoding clock signal utilized to decode the encoded data is used for regenerating a position of the encoded data on a time axis.
