Abstract: PCM data with time information is read out by an ATAPI controller 4. PCM data with time information is read out from the ATAPI controller 4 into an AV decoder 11 while ascertaining coincidence between the amount of transmitted data and that of received data. The time information is output in synchronization with the PCM data. Therefore, PCM data and time information can be easily synchronized with each other, and a dedicated line for PCM data can be omitted.

Abstract: An optical disk apparatus includes a data conversion unit that converts input video data into record data, a data record unit that temporarily stores the record data in buffer memory and writes on to an optical disk while maintaining data continuity, and a control unit that controls the data record unit and the data conversion unit. The control unit acquires free space of the buffer memory in a reference data unit smaller than a video object unit when the video data is converted into record data in the video object unit, instructs to divide the record data into the reference data units and to store in the buffer memory based on the acquired free space, to convert the video data into record data when the record data is stored, and to divide termination processing data in to the reference data units and to store when a record stop instruction is input.

Abstract: Disclosed is a digital sound signal processing apparatus which performs predetermined sound processing to a digital sound input signal of a predetermined format and is capable of outputting a digital or an analog sound signal from a plurality of output terminals, the apparatus including: delay units severally provided at preceding stages of the plurality of output terminals; a delay time setting unit to set delay times of the delay units respectively; and a sound output selection unit to select an output terminal that outputs the sound signal among the plurality of output terminals, wherein the delay time setting unit refers to sound output timing of a sound output apparatus connected to one of the output terminals as a standard to set the delay time of the delay unit of the other of the output terminals, when a plurality of output terminals are selected.

Abstract: When an input video signal is not present, a signal presence/absence deciding unit decides that the input video signal is not present. A switch unit is switched to an output side of a flash memory in response thereto. Then, fixed image data from the flash memory 18 is supplied to an MPEG 2 encoder. Compressed fixed video data outputted from the MPEG 2 encoder is recorded on an optical disk. That is, when there is no input video signal, a fixed image is recorded on the optical disk in place of a noise image. Accordingly, even when the optical disk 15 is reproduced, the noise image is not outputted and the fixed image is outputted instead thereof.

Abstract: An optical disk apparatus includes an information readout unit that reads out information recorded on an optical disk while seeking, a storage unit that temporarily stores the information read out, and a control unit that performs readout and seek controls for the information readout unit and performs readout and writing controls for the storage unit. When a readout error detection signal is inputted during reading out the information, the control unit seeks from a retry address preceding an error-detected address by a predetermined amount, and subsequently, when the readout error detection signal for the same address is inputted, seeks from a retry address further preceding the immediately preceding retry address by a predetermined amount. When the readout error detection signal is inputted on performing retry seek actions predetermined times, the control unit seeks from a head address of a video object unit preceding the error-detected address by a predetermined amount.
