Abstract

See full text

A reproduction apparatus and a reproduction method by which an error of time information that arises from interruption of power supplied to a timer that manages the term of term-managed contents data is minimized to allow accurate term management of the contents data. The timer produces time information when power is supplied to the timer from a cell, but the timer stops operating when no power is supplied thereto. The time information produced by the timer is stored into a memory, and the memory holds the stored time information when no power is supplied to the timer. When power from the cell is restored to the timer, the timer is set accordingly to the time information stored in the memory, so that the timer may thereafter produce correct time information thereby allowing term management of the term-managed contents data to be performed accurately.
