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 non-linear preemphasis-deemphasis system comprises nonlinear preemphasis and deemphasis circuits. The preemphasis circuit comprises a non-linear signal increaser (10) for increasing the amplitude of a signal component higher than a predetermined frequency of an original signal to a predetermined threshold level in accordance with the frequency, a first adder (14) for adding the output of the signal increaser (10) to the original signal, a non-linear signal decreaser (16) having a characteristic inverse to that of the nonlinear signal increaser (10), and a second adder (20) for adding the output of the signal decreaser (16) to the original signal. The nonlinear deemphasis circuit comprises a non-linear signal decreaser (30) having a characteristic inverse to that of the non-linear signal increaser (10) and serves to decrease the amplitude of the signal component higher than the predetermined frequency of the received signal to a predetermined threshold level in accordance with the frequency, and a subtracter (34a) for subtracting the output of the signal decreaser (30) from the received signal.

Abstract: Video and information signals, such as audio signals, are recorded (16, 17) in oblique tracks on a magnetic tape (18) having a wrap angle of no more than 180 DEG by timebase converting (3A, 3B, 6a, 6b, 11) at least the video signal which then is time division multiplexed (14A, 14B) with the information signal. The time division multiplexed signals are recorded (16, 17) sequentially in a length of rack that is less than the wrap angle to form successive tracks.
