Referring to a condition flag of the condition flag register every sampling period of the DSP, the DSP can change the content of a process every sampling period in accordance with the set status of the condition flag. The DSP sets the condition flag in the condition flag register at the beginning of a sampling period of the DSP by a set instruction, and resets the condition flag at the end of a sampling period by a reset instruction. The DSP may be modified to automatically reset the condition flag at the end of the sampling period in which the condition flag has been set.

摘要： The present invention provides an apparatus and a method that judge whether contents recording processing is in progress and make it possible to execute reproduction processing under accurate control. A recording control process for executing contents recording processing generates reproduction synchronization management information having a reproduction synchronization management information name, which is uniquely decided from a reproduction management information name of reproduction management information, and stores the reproduction synchronization management information in a directory that is automatically erased at the time of system startup or a volatile memory that is erased at the time of power off. A reproduction control process extracts reproduction synchronization management information on the basis of a reproduction management information name and judges whether contents to be reproduced are being recorded to execute control of a reproduction process. At the time of restart after power supply interruption, the reproduction synchronization management information is reset, and the reproduction control process is prevented from performing control misunderstanding that contents are being recorded simultaneously.
