摘要： A magnetic detection apparatus includes a first comparison circuit that waveform-shapes the amplitude of a detection signal from magneto-electric transducers by DC coupling, a third comparison circuit that waveform-shapes the detection signal by AC coupling, an oscillation circuit having a natural frequency, a control circuit that counts the output of the first comparison circuit by using the oscillation means, and a selection circuit that selects the output of the first comparison means and the output of the second comparison means. The control circuit counts rising from the next rising or falling from the next falling of an output rectangular wave of the first comparison circuit, and provides output to the selection circuit at the time point at which the count value reaches a desired value. The selection circuit selects and outputs the output rectangular wave of the first comparison circuit or the third comparison circuit.

摘要： A disc apparatus includes a readout unit, an audio signal output unit, a memory, a switch, and a controller. The readout unit reads out data from a disc wherein the data includes at least digital audio data. The audio signal output unit produces an audio signal output in accordance with the digital audio data. The memory stores the digital audio data read from the disc by the readout unit. The switch switches the digital audio data supplied to the audio signal output unit between the digital audio data stored in the memory and the digital audio data currently being read by the readout unit. Furthermore, the controller controls the readout unit and the memory so that, prior to a playback start operation, the digital audio data of a first predetermined period from a beginning of at least one program is read out by the readout unit and stored in the memory; controls the switch so that, at a beginning of the playback start operation, the audio signal output unit produces the audio signal output based on the digital audio data stored in the memory; and controls the switch so that, a second predetermined period after the start operation, the audio signal output unit produces the audio signal output based on the digital audio data currently being read out by the readout unit.

摘要： A coding apparatus for reduction and variable-length-coding of digital image data, wherein the image data is once variable-length-coded to obtain a variable length coded data. The variable length coded data is coded again to produce an amount of data. The amount of data is used to select an optimum quantization level. The variable length coded data is then coded again with the optimum quantization level to maximize a recording density of the twice coded data on a recording medium.

摘要： A magnetic recording and reproducing apparatus records audio signals digitized by rotary heads (9, 10) on a magnetic tape (12), and reproduces the recorded audio signals. Clock signals and time code data are extracted from externally inputted time code signals by means of a demodulating circuit (72), and phase difference between the frame clock signals and the reference signal is detected by a phase difference detecting circuit (74). A microcomputer (23) assigns the phase difference information and the time code data to sub code packs and stores the same in the memory circuit (40). The stored phase difference information and the time code data are recorded on the magnetic tape. In reproduction, the microcomputer outputs and original time code signals responsive to the reproduced phase difference information and the time code data.
