摘要： A processing system for reproduced audio digital signals used in an audio PCM (pulse code modulation) recording/reproducing system using a recording/reproducing apparatus such as a video tape recorder having a dropout-compensation circuit is disclosed. The reproduced signal processing system is connected to receive digital information signals reproduced through the dropout compensation circuit from a recording medium on which audio information signals are recorded in the form of digital data words and includes circuit means for detecting whether a reproduced digital signal is dropout-compensated or not and circuit means for adding an error pointer to a reproduced digital signal which is detected as being dropout-compensated.

摘要： A signal copy device for a digital record/reproduction system includes an encoding circuit for producing a first digital encoded signal corresponding to an analog audio signal. The encoding circuit is connected to a first VTR through a switch section of a switch circuit and a first digital signal processor. A second VTR reproduces and generates a digital encoded audio signal to be copied. The switch circuit is connected to the encoding circuit and the second VTR. The switch circuit includes two switch sections which operate in cooperation with each other. When a reproduction signal is generated from the second VTR, the two switch sections are switched. The reproduction signal is supplied to the first VTR through these switch sections, thus accomplishing copying.

摘要： A wave-shaping circuit which comprises a comparator for comparing the level of a signal reproduced from a magnetic tape on which, for example, PCM signals are recorded with the level of a reference signal, and a D flip-flop circuit for holding an output signal from the comparator for a prescribed period. Where the reproduced signal has a higher level than the original level of the reference signal, then the reference signal is made to have a higher level than the original level by an output signal from the D flip-flop circuit, that is, an output signal from the comparator. Where the reproduced signal has a lower level than the original level of a reference signal, then the reference signal is made to have a lower level than the original level by the output signal from the comparator. As a result, strains occurring at the high density recording are not reproduced.

摘要： Reinforcement of a system renewability is realized skillfully utilizing properties peculiar to a system. As a result, there is produced such a new effect as to similarly reinforce required specification with respect to copyright protection of a content recorded in a medium for exclusive use in reproduction and a recordable medium. In a system which encrypts information such as a content to record/reproduce the information, design is made so that encryption/decryption processing information differs for a device (software (S/W) main body device) whose main body is software constituted of a recording/reproducing drive of a recording medium and a personal computer (PC), a device (hardware (H/W) main body device) whose main body is hardware integrally containing a drive and data coding/demodulation processing, and the medium for exclusive use in reproduction and the recording medium.

摘要： When detecting a rotational position of a seconds hand, it is determined whether data stored in a register in correspondence with a supply state of a drive current previously supplied to a coil of a stepping motor is “0”. When the data is “0”, the rotational position of the seconds hand is optically detected. When the data is “1”, the seconds hand is rotated one step, and then, the rotational position of the seconds hand is optically detected. Even though the seconds hand is shifted one second, the position detection is executed every two steps.

摘要： A row of the data block which is a set of the data sector is distributed to constitute two blocks. In this case, as a distribution condition, an even-number row block of the even-number sector and the odd-number row block of the even-number sector, the odd-number row block of the even-number sector and an even-number row block of the even-number sector are obtained. Then, the block is aggregated in the transmission order, and an outer parity is scattered to each sector to form an interleaved form.
