Abstract: PROBLEM TO BE SOLVED: To make it possible to select a sub-image and improve convenience by combing display information meaning that it is not at the stage for changing over a image, when 1st and 2nd program information are not reproduced at reading of disk information, demodulating an output signal from a pickup means, storing the demodulated multi-image composition information, and inputting a change-over signal. SOLUTION: This reproducing device decides whether or not a parental consent mode should be set, and displays a comment picture if should be set. At reproducing of multi-image recorded disk, the reproducing device reads the data of the disk, and at detecting of a code showing the presence of a multi-image in a sub-code, the device refers to link information and decides the presence or absence of a linked program bar. If the program is detected, the device displays an image to the effect that it is not at changeover stage, and when a multi-image is changed over, handleability of operation is improved for a user by displaying data information corresponding to the present.

Abstract: PROBLEM TO BE SOLVED: To realize reproduction of a mu1ti-scene by displaying an identification signal for the first and second program information to generate a first menu image and inputting a secret code to generate a second menu image. SOLUTION: A first program information and a second program information which may be reproduced by replacement with the first program information are recorded in a data area and existence of a previous selecting information from the control data is judged at the end of a program bar. When existence of the multi-scene selecting information is judged, the program bar of the selected scene is reproduced but in the case of the parental consent mode, a secret code input request for canceling this mode is displayed. A masked image is switched to the normal image to reproduce multi.-scene by inputting a secret code to the secret code input image.

Abstract: PURPOSE:To provide a disk reproducing device exclusively used for CD+MIDI disk capable of surely synchronizing respective regenerated sounds by means of an audio signal and a control signal for electronic musical instrument with each other. CONSTITUTION:A signal for adjusting synchronization is recorded on the leading part of main data and sub-code data on a CD+MIDI disk 11 prior to an audio signal and an MIDI signal. The phases of the synchronizing signals of the respective data after signal processing are compared by means of a phase comparator 21 at the time of reproduction and the phase difference signal is fedback to a MIDI decoder 17. A digital memory 20 for temporarily storing the sub-code data and generating optimal timing for sending the MIDI signal to an electronic musical instrument 18 is built in the MIDI decoder 17 and the increase or decrease of the delay time is adjusted according to the output of the phase comparator 21 so that the phase difference of the respective synchronizing signals becomes zero.

Abstract: PURPOSE:To measure a bit length, by detecting that the counted value of a counter reaches a value corresponding to an about half length of the next bit length and counting the number of clock pulses during the time ending the zero- crossing time in the rise (or fall) direction. CONSTITUTION:The counted value of a counter 9 which is detected by a NAND gate 11 is so set that bit signals having a 3.5-bit length or longer are judged to be 4-bit or longer signals and bit signals having a length shorter than 3.5 bits are judged to be 3-bit signals. When the bit signal reaches the trigger level during rising, a zero-crossing detecting circuit 2A generates an output pulse, and output clock pulses from a clock pulse oscillator 3 are supplied to the counter 9 and are counted; and when the bit signal reaches the trigger level during falling, a zero-crossing detecting circuit 2B generates an output pulse, and the supply of clock pulses to the counter 9 is stopped. The length of the 3-bit signal is measured by the time from the rise zero-crossing time to the fall zero-crossing time of a detection EFM signal.
Abstract translation: 目的：为了测量位长度，通过检测计数器的计数值达到对应于下一个位长度的大约一半长度的值，并在结束过零时间的时间内对时钟脉冲数进行计数 （或下降）方向。 构成：由NAND门11检测的计数器9的计数值被设置为使得具有3.5位长度或更长的位信号被判断为长度短于3.5的信号和比特信号的4比特或更长 比特被判定为3位信号。 当位信号在上升期间达到触发电平时，过零检测电路2A产生输出脉冲，并且将来自时钟脉冲振荡器3的时钟脉冲输出到计数器9并进行计数; 并且当位信号在下降期间达到触发电平时，过零检测电路2B产生输出脉冲，并且停止向计数器9提供时钟脉冲。 3位信号的长度由检测EFM信号的上升过零时间到下降过零时间的时间来测量。

Abstract: PROBLEM TO BE SOLVED: To select a sub-image and to improve convenience by demodulating an output from a pickup means, storing multi-image composition information from the demodulated output, and combining identification information of program information being reproduced when either a 1st or a 2nd program information is being reproduced. SOLUTION: When a disk is inserted in this reproducing device, it reads management data in a management area, and stores it in a work memory. When a multi-image recorded disk is reproduced, the device reads the data of the disk, and when it detects a code showing the presence of a multi-image in a sub-code, it refers to link information and decides the presence or absence of a linked program bar. When the multi-images are changed over, an image is displayed by decoding the number of a specified data string to be stored in the work memory and the identification numbers of the disk and the program.
