摘要： An error detection and correction device in which a word train including a number of error correction codes each constructed from a plurality of words is input, the error correction code being of the type that two error words can be corrected by each error correction code. Error words are corrected by using the error correction code within the word train. Mode setting information associated with an error rate of the word train is generated, and an error correction means is controlled in a first or a second error correction mode depending on the mode setting. The error correction means corrects one or two error words for each error correction code in the first error correction mode and corrects only one error word for each error correction code in the second error correction mode.

摘要： The present invention relates to an encoding apparatus for digitizing and encoding an input image signal, the input image signal being sequentially sampled to sequentially form sample signals at respective sample points. The encoding data which respectively correspond to the sample signals at respective sample points are formed, and the plurality of resultant encoding data are sequentially output on a group unit basis of k (k being an integer equal to or greater than 2) encoding data in accordance with the order different from the forming order of the encoding data. In accordance with a combination of the k encoding data which have been output, the k encoding data are converted into the data train having less DC and low frequency components and output, so that the image signal can be highly efficiently encoded.

摘要： A digital signal recording apparatus includes first circuitry for forming digital video data, and second circuitry for forming digital audio data. Third circuitry is provided for forming (a) video synchronizing blocks each of which comprises a predetermined number of digital video data and synchronizing data, and (b) audio synchronizing blocks each of which comprises a predetermined number of digital audio data and synchronizing data. Recording circuitry is provided for recording the video synchronizing blocks and the audio synchronizing blocks in tracks formed on a recording medium, the tracks being generally aligned in the direction of travel in the recording medium. The recording circuitry includes time-division multiplexing circuitry for time-division multiplexing a predetermined number of video synchronizing blocks and a predetermined number of audio synchronizing blocks to produce a data sequence for each of the tracks. The time-division multiplexing circuitry produces different data sequences for neighboring tracks.
