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： An information recording and reproduction apparatus for recording and reproducing the information supplied through the transmission line is capable of protecting the copyright by limiting the reproduction of the recorded information. A main information signal supplied through the transmission line and a deadline signal attached to the main information signal and representing the reproduction deadline of the main information signal are recorded and reproduced by a recording device and a reproduction device respectively. A temporal information signal representing the date and time is acquired. The deadline signal reproduced is compared with the temporal information signal acquired. The reproduction output of the main information signal is cut off in accordance with the comparison signal produced by the comparison. In the case where the temporal information has passed the deadline, the reproduction output of the main information signal is cut off.

摘要： This invention relates to an error correction upon reproduction of digital signals. The error correction is performed by decoding code words such as cross-interleaved Reed Solomon codes, in which first code blocks are formed by a plurality of information words which are in the first arrangement state and a plurality of first check words which are produced by codes associated with the plurality of information words with a Hamming distance of d.sub.1, and second code blocks are formed by a plurality of information words and a plurality of first check words which are in the second arrangement state and which consist of the said plurality of information words and the said plurality of first check words which are respectively included in the different first code blocks, and by a plurality of second check words which are produced by codes associated with the plurality of information words and the plurality of first check words with a Hamming distance of d.sub.2. At the first decoding stage, errors are detected and at the same time the flags indicative of the decoding states are added with respect to the second code blocks. At the second decoding stage, in accordance with the contents of the flags and on the basis of a combination of p.sub.2 and q selected from their combinations satisfying 2p.sub.2 +q.ltoreq.d.sub.1 -1, errors are detected and errors of p.sub.2 words are corrected and erasures of q words to which the flags were added are corrected with respect to the first code blocks.

摘要： A rotary-head PCM data recorder in which PCM signals of m in number, a synchronizing signal, control signals related to the PCM signals, and a parity signal for error detection and correction are formed into data blocks, and data blocks of n in number are recorded on one track of a magnetic tape. Among the control signals, bits of signals common to n data blocks (i.e., information needed once for each track) are formed in distributed data allocated in a group of consecutive blocks or tracks, and multiple block distributive control data are recorded on one track multiple number of times, or multiple track distributive control data are recorded along n block strings a multiple number of times. In reproduction, block or track distributive data are composed to reproduce the control signals. The recorder thus arranged reduces the bit number needed for the control signals and compensates dropout of reproduced data due to scratches on the tape and the like.
