摘要： Digital companding without range bits involves comparison of a digital input with predetermined boundaries separating a plurality of numerical ranges, detection of a numerical range to which the digital input belongs, generation of an off-set unique to each numerical range, bit-shifting of the digital input, and addition of the bit-shifted input with the generated off-set to provide a companded digital output which is in one-to-one correspondence to the digital input. The off-set values are stored in a memory.

摘要： A PCM signal processor which converts an analog signal into a digital signal to transmit or record the digital signal. When the PCM signal processor receives a PCM signal whose data has been compressed in such a manner that one or more lower bits are cut off from a plurality of bits for forming the PCM signal and indicating the signal level of the analog signal, in accordance with the signal level of the analog signal, one or more bits corresponding to the number of bits having been cut off are added in the processor to the compressed PCM signal at the position following the least significant bit of the compressed PCM signal. Correction data indicating about one half the largest one of numerical values that can be expressed by the added bit or bits, is given to the added bit or bits.

摘要： An offset compensation circuit for compensating a DC offset which occurs in a circuit line including an A/D converter or an A/D and D/A converter in which not only the polarity bit of digital data but also information concerning the amplitude of an analog input signal are applied to an integrator to precisely compensate an offset voltage in a circuit line. The level of a proper offset compensation voltage is provided even when an input analog signal such as a music signal is absent, and when an A/D and D/A converter is provided which can perform both A/D conversion and D/A conversion the DC offset can be precisely compensated shortly after the change of the mode from D/A conversion to A/D conversion.

摘要： In a stationary head type PCM recorder having an A/D converter for sampling an analog signal and converting the analog signal to a digital signal, a signal processing circuit including data delay means for adding an error detection and correction code and a predetermined signal to the digital signal for each error correction group of a predetermined number of samples, and a multi-track head for recording an output of the signal processing circuit on a plurality of tracks of a magnetic record medium and reproducing the signals recorded on the magnetic record medium; incorrectability of the error detection and correction code for a burst error in the output analog signal due to a burst error in the reproduced output is reduced by delaying parity data by the error detection and correction code and the digital signal data by different delay times such that the digital signal data are dispersely recorded in a track direction and a tape transport direction, and allotting the delayed data to the multi-track head such that the data of the adjacent sample points are spaced from each other by at least the distribution length of the parity data and the parity data is arranged between the distributed adjacent data.

摘要： This invention enhances usability while performing copy control when recording a digital broadcast program specified as “Copy One Generation”. In this copy control method, digital contents received by a first recording apparatus are copied to a second recording apparatus via a network interface and to a third recording apparatus via a local interface according to the copy control information received by the first recording apparatus. When the received control information indicates “Copy Free with Limit of the Number” permitting a predetermined copy number of multiple copies, the received digital contents can be recorded and managed in the first recording apparatus to be copied up to the predetermined copy number. The digital contents copied to the second recording apparatus are managed as “No More Copies”, and the digital contents copied to the third recording apparatus are managed as “No More Copies and No Move”.

摘要： The usability while performing copy control can be enhanced in the case of recording a digital broadcast program for which recording of one generation is permitted (“Copy One Generation”). When an output route in the case of copying digital contents from a first recording apparatus to a second recording apparatus is via LAN, authentication is executed between the first recording apparatus and the second recording apparatus. The capability of a move process with a predetermined copy number of multiple copies being kept is confirmed, and dedicated key information is shared to be used for encryption and decryption of the digital contents moved with the predetermined copy number of multiple copies being kept. Then, the digital contents recorded and managed in the first recording apparatus is added with the information about the predetermined copy number of multiple copies, and transmitted.
