    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.

    摘要: This invention manages temporary storage of content data according to guidelines. According to this invention, when temporary storage of a recording transport stream TS3 which is allowed to be temporarily stored in a recording medium so as to be reproducible only within a temporary storage allowable time is managed, a reproducible start point indicating a start point from which the recording transport stream TS3 can be reproduced is associated with a first time stamp out of the time stamps of the GOPs of the recording transport stream TS3, and every time when a period from a time stamp associated with the reproducible start point to the current time reaches a temporary storage allowable time, the reproducible start point is re-associated to another time stamp following the time stamp, so that an overtime part of the recording transport stream TS3 can be removed from a reproducible range so as to easily and correctly disable its reproduction, thus being capable of easily and correctly managing the temporary storage of the recording transport stream TS3.

    摘要: A digital signal processor (DSP) comprises a condition flag register directly accessible by the control microcomputer. 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: A digital signal processor (DSP) makes a conditional judgment based on a value held in a flag register in accordance with the result of an arithmetic operation, selectively outputs data representing either a predetermined value or "0" in accordance with the result of the decision, adds the value of the output data to a value held in a coefficient memory address register, and holds the resultant value in the address register. Accordingly, in executing pipeline processing, a read address of the coefficient data memory can be directly designated without altering the flow of a program, thus shortening the processing speed and facilitating the programming.
