摘要： PURPOSE:To execute consecutive recording which can match tracks and control track signals (CT) even to a tape recorded by another equipment before and behind an editing point by making the phases of a reproducing CTL and a recording CTL coincident by resetting an (n) frequency divider circuit, which divides the frequency of a capstan reference signal into (n), according to a reset pulse. CONSTITUTION:This device is equipped with a control track signal head 1 and an edge detection circuit 22 which detects the edge of a reproduced control track signal pulse reproduced by the control track signal head 1. According to the reset pulse outputted in the case of edge detection, this edge detection circuit 22 resets the frequency dividing pulse of the capstan motor reference signal in a frequency divider circuit 23 and as the result, a recording control track signal pulse is generated and outputted with the same frequency and phase as those of the reproduced control track signal pulse. Thus, when consecutive recording is executed onto the tape recorded by the other equipment, the recording track and the CTL can be matched at the editing point.

摘要： PURPOSE:To switch a switching circuit according to the detected failure of a sound reproducing device or an out of synchronism with a time code, etc., and to constantly obtain a sound signal corresponding to a video on a film by introducing the reproduced sound outputs of an optical track reproducing machine which reproduces a sound track and of the sound reproducing device to a reproducing device through the switching circuit. CONSTITUTION:A sound signal reproduced by the sound reproducing device 5 is selected and sent to the reproducing device 7 by the switching circuit 3 of the sound reproducing device for movie. When the failure of the sound reproducing device 5, the out of synchronism with a time code or the out of synchronism due to a time code skip caused by the use of an edited film occurs in a condition described above, it is detected by a detecting part 6 and the circuit 3 is switched by the detecting signal. Then, the sound signal reproduced from the sound track 10 obtained by the optical track reproducing machine 2 is selected and sent to the reproducing device 7 by the circuit 3 according to a switched result. When the sound reproducing device 5 is repaired or the time code is resynchronized, the circuit 3 is switched on the side of the sound reproducing device 5.

摘要： PURPOSE:To enable automatic speech signal edition and the labor saving of an editing work by performing the dubbing edition of a recording medium on which speech signals are recorded according to the front and rear time codes of the discontinuous points out of time codes recorded on an edition- finished movie film. CONSTITUTION:A magnetic tape on which continuous time codes before edition are recorded is dubbing-edited by an editing device 4. At this time, dubbing the speech signals of a part sandwiched by the front and rear time codes of the discontinuous points is eliminated by the control of the time codes recorded on the recorder. At the next stage, the magnetic tape is reproduced by the editing device 4 and reproduced speech signals are supplied to a sound track recorder 5. Hereby, the speech signals are recorded on the sound track of the movie film. In this case, time codes obtained from a moving picture projector 1 are read by a time code reader 2 and the editing device 4 is simultaneously controlled by these time codes. Thus, only the cutting-edition of the movie film is performed and the speech signals are automatically edited according to the time codes.

摘要： PURPOSE:To attain coding/decoding processing by providing a circuit controlling the signal processing of a coding system and a decoding system operated asynchronously so as to control a processor capable of constituting the coding circuit and the decoding circuit by means of one circuit through the program. CONSTITUTION:A recording signal 1 is subject to interleave 2, and a decoded signal 5 is inputted to a coding/decoding processor 13 by an instruction 4. The decoded signal 19 is subject to interleave 18 and the decoded signal 15 is inputted to the processor 13 by an instruction 14. Since coding/decoding signals 7, 8 are asynchronous, when a start signal of the other processing is inputted to a control circuit 9 during the one processing, the other processing is started as soon as the preceding processing is finished. For example, the control circuit 9 inputs the signal 14 to the circuit 18 by the decoding start signal and while the signal 14 is at 'L', the decoded signal 15 to the processor 13 is in standby. While the mode signal from the circuit 9 is at H, the processor 13 selects the program from the decoding processing and becomes the decoding circuit, the busy signal 11 is brought into L level and the signal 16 to be decoded is outputted as the reproduction signal 17 via the circuit 18.

摘要： PURPOSE:To edit a sound fully electronically by adding the same address codes to a magnetic film capable of traveling in perforation synchronism with a movie film and a sound signal corresponding to the magnetic film. CONSTITUTION:When the movie film 2 to be edited and the magnetic film 3A to be edited where a time code signal is recorded are made to travel simultaneously, a sound signal part to which the same time code signal as the time code signal from a film editing machine 1A is added is reproduced and displayed on the monitor 23 of a console panel to know which part of which kind of sound is being reproduced at a glance. A time code display device 49 corresponding to an image projected on a viewer 4 is fitted on the film editing machine 1A and the same time code is displayed on the monitor 23 and a time code display device 49. The video film to be edited is made to travel continuously, an unnecessary part such as an NG scene is deleted, and the film is joined again. Consequently, a sound is edited electronically without touching the recording medium directly.

摘要： PURPOSE:To obtain sound of high quality and to readily and smoothly join sound to sound at a film joint by providing a sound reproducing device which performs reproduction previous to absolute time information reproduced by a moving picture projector by a prescribed time and supplying a delay memory circuit controlled by the absolute time information reproduced by the movie film with the output of the sound reproducing device. CONSTITUTION:The absolute time information and a sound signal which is used instead of a sound signal stored in the optical sound track 8b of the movie film 8 are separately recorded in the recording medium of the sound reproducing device 2 in advance. By the absolute time information inputted from the moving picture projector 1 and the absolute time information reproduced by the device 2 itself, a synchronized operation with such an offset as that the device 2 performs reproduction previous to the moving picture projector 1 by the necessary prescribed time is performed. Besides, the sound signal reproduced by the device 2 is sent to a delay memory 3 and the absolute time information reproduced by the moving picture projector 1 is sent to the delay memory controlling circuit 5. Therefore, when the absolute time information is continued, a circuit 3 is controlled so that the input-output delay quantity of the circuit 3 is set at definite value.

摘要： PURPOSE:To prevent the generation of the abnormal sounds, etc., by sampling and holding the pulse width reproduction signal undergone the waveform shaping and holding the level of the signal which is sampled and held right before the drop-out in a section corresponding to the drop-out. CONSTITUTION:A PWM (pulse width modulation) reproduction signal undergoes the waveform shaping via a PWM reproduction circuit 3 and is inputted to a programmable PLPF 4. At the same time, a speed data production circuit 10 counts the sampling frequency to convert this counted frequency into the set data of the cut-off frequency of PLPF 4 and 6 respectively via a PWM sampling frequency extracting circuit 8 based on the high frequency clock produced by a high frequency reproducing clock generator 9. Then the set data are sent to both PLPF 4 and 6. An S/H (sampling/holding) signal production circuit 11 detects the drop-out and produces an S/H control signal and an S/H signal to send these signals to an S/H circuit 5. The circuit 5 holds the level of the signal sampled and held right before the drop-out in a section corresponding to the drop-out section. Thus an abnormal signal waveform is never produced.
