Abstract: A compensating deemphasis circuit (50) is connected to a preemphasis circuit (10A) in series. The deemphasis circuit (50) has the same characteristic as a deemphasis circuit (20B) provided in a playback system. An input signal and an output signal which are connected in series are supplied to a subtracter (41). The subtracter extracts a distortion component. This distortion component is overlapped (43) to an output signal of the preemphasis circuit (10A) through a weight coefficient generating device (42). When the signal passes through the deemphasis circuit in the record and playback system and that in the playback system, the distortion component is canceled.

Abstract: Copying, dubbing or reproducing copyrighted digital data can be inhibited or restricted to properly protect a copyright. AV data recorded on a pre-recorded tape is output from a reproducing unit of a first digital VCR with protective information indicating whether the copy of the AV data is inhibited or not. The protective information is input with the A/V data to a second digital VCR. Copy permission information of a blank tape loaded in the second digital VCR is discriminated and the second digital VCR records the AV data supplied from the first digital VCR based on the protective information and the copy permission information.

Abstract: A noise reducing circuit for removing noise from an incoming video signal comprises a first circuit (1, 2) including a high-pass filter (1) for extracting a high band signal component of the incoming video signal and a limiter (2) for amplitude-limiting an output signal of the high-pass filter (1), a second circuit (4, 5) for detecting a correlation in the vertical direction of the video signal, a weighting circuit (6) for weighting an output signal of the second circuit (4, 5) in response to the output signal of the high-pass filter (1), a first calculating circuit (7) for adding an output signal of the first circuit (1, 2) and an output signal of the second circuit (4, 5), and a second calculating circuit (3) for subtracting an output signal of the first calculating circuit (7) and the video signal from each other.
