    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.

    摘要: In order to provide a recording and reproducing device that allows a user to select and manage arbitrary play lists, a unit of management for managing all registered play list information and an upper management hierarchical level are added. The unit of management is adapted to be handled on the same level with unified information that indicates a reproduction range of all AV data. User-defined unified information is adapted to be handled on the added management hierarchical level. The user-defined unified information is formed to allow arbitrary reproduction ranges contained on a lower hierarchical level to be registered.
