摘要： PROBLEM TO BE SOLVED: To provide a digital data processing method capable of making a buffer memory system simple constitution. SOLUTION: A timing control part 13 controls the access timing when the audio digital data digitized at a sampling frequency fs=32kHz are written in a buffer memory 3 through an fs system data writing buffer b1 , or are read out through an fs system data reading buffer b5 according to the access timing when the audio digital data are read out at RF system = 16MHz from a buffer memory 3 through an RF system data reading buffer b3 , or are written in through an RF system data writing buffer b7 .

摘要： PROBLEM TO BE SOLVED: To increase a data transfer speed by making the maximum value of a seeking time small for recording/reproducing time sequential data such as a video signal or an audio signal in a disk storage medium. SOLUTION: A harddisk is divided into, for instance four segments S1 to S4 and, while write segments are sequentially switched, video/audio information is written. That is, data 1 of time t(0) is first written in the head address 0 of the segment S1 located in the outermost periphery. Then, data 1 of time t(1) is written in the head address 1 of the segment S2. Hereinafter, similarly, data of t(2) is written in the head address 2 of the segment S3, data of t(3) in the head address 3 of S4, data of t(5) in the second address 5 of S4 and data of t(6) in the second address of S3, and while the segments are sequentially changed for writing like this, and when data is written in the segment of the innermost or outermost periphery, the changing direction of the segments is inverted and data is written. Thus, the maximum value of a seeking time is reduced to 174 for writing data in continuous addresses.

摘要： PURPOSE: To record/reproduce a moving picture without providing a FIFO in the outside by performing the rotational control of a magnetic disk and controlling the timing of an interface in synchronisim with a synchronizing signal. CONSTITUTION: At the time of reproducing the magnetic disk, the synchronizing signal from a synchronizing signal generating circuit 9 is transmitted to a CPU 7 and a terminal 6 via a switch 60. The synchronizing signal of the terminal 60 is transmitted to a hard disk controller CNT 3 and a spindle servo circuit 20. The circuit 20 performs the rotational control whose phase is locked with a vertical synchronizing signal and the signal reproduced from a magnetic disk 10 via a magnetic head 11 is transmitted to the CNT 3 via a modulation circuit 12 to be subjected to an error correcting processing. The CNT 3 transmits data to decoder circuit 91 via an interface 5 in agreement with the phase of the vertical synchronizing signal. The synchronizing signal from the circuit 90 is added to data transmitted to the circuit 91, and is video signal is sent to a terminal 90.

摘要： PURPOSE:To obtain the MUSE signal reproducing device in which troublesome phase matching adjustment such as use of an oscilloscope is not required. CONSTITUTION:A reproducing signal from an optical disk 101 through an optical head 102 is demodulated by an FM demodulator 103 to obtain a MUSE signal SMUSE. The MUSE signal SMUSE is fed to a TBC 104, in which jitter is eliminated and the resulting signal is given via an output terminal 117 to a MUSE decoder 200, in which the signal is demodulated to obtain a high vision signal SVo. The high vision signal SVo is fed to an input terminal 121, a phase comparator 109 compares phases of synchronizing signals PHo, PVo separated from the high vision signal SVo and phases of synchronizing signals PHr, PVr separated from the high vision signal SVr (synchronizing reproduction reference signal) fed to an input terminal 107 and its comparison error signal controls an oscillated frequency of a VCO 110. Thus, the reproduction speed is controlled to match the phase of the high vision signal SVo with the phase of the high vision signal SVr automatically.
