摘要： Error correction of digital signals is suited for codes having error detection and correction words, such as doubly-encoded Reed-Solomon code. In a first decoding, at least error detection is effected and flags indicating decoding conditions are added. In a second decoding, error detection for first code blocks and error correction for S2 words at unknown locations and E flagged word erasures, where d1 is a Hamming distance and S2 and E satisfy a relation of 2S2+E.ltoreq.d1-1, are parallely or sequentially effected, and a combination of S2 and E having a high correction capability and a low probability of miscorrection is selected from a plurality of correction results of error locations and the numbers of flags added at the first decoding, and the word errors are corrected based on the selected combination.

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： 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： A method of transmitting a digital signal in the form of successive signal frames containing codes for detecting and correcting errors of the digital signal for reducing degradation in the quality of the reproduced sound due to generation of the code errors in a digitized audio signal transmission system. An analog signal such as an audio signal is sampled and subjected to A/D conversion. The sample word thus obtained is divided into a plurality of symbol elements. Parity words for detecting and correcting code errors are added to every group of a predetermined number of the information symbols through an interleave procedure before being transmitted. The method includes the steps of applying a first frame of symbols, taken one from each input channel, and having a first arrangement state, to a first error-correcting code encoder to generate a series of first parity words; delaying each of the symbols in the first frame and each of the first parity words by a respective different delay time in a unit of the sample word at a delay line to provide a resulting second frame of symbols in a second arrangement state; applying the second frame of symbols to a second error-correcting code encoder to generate a series of second parity words; and transmitting said second frame of symbols together with said second parity words.

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.
