    摘要： The digital VTR includes an extractor, variable-length decoder, quantizer and variable-length encoder. The extractor receives digital data divided into blocks, and which is quantized and variable-length coded on a block-by-block basis. Portions of the digital data are encoded according to a first type of encodation, and other portions of the digital data are encoded according to a second type of encodation. The extractor identifies and extracts the digital data encoded according to the first type of encodation. The variable-length decoder variable-length decodes the extracted portions of the digital data, while the quantizer quantizes the decoded data output by the variable length decoder. The variable length encoder variable-length encodes the quantized decoded data to form special-playback data. Alternatively, a convertor converts the extracted portions of the digital data into variable-length coded data having different quantization steps to form the special-playback data.

    摘要： A codeword contains information symbols representing elements of a Galois field, a parity check symbol generated using a certain element of the Galois field, and additional check symbols generated using a polynomial of which this certain element is not a root. The reliability of corrected codewords is assessed by counting the number of symbols found to be in error, or by counting the number of symbols having at least a certain number of bits in error. When a row-column array is decoded, rows of intermediate reliability are not corrected but their error patterns are stored in a memory, and columns of intermediate reliability are corrected if their error patterns match the error information stored in the memory.

    摘要： A management unit (110) which issues a digital certificate to a new transmission unit (410) includes a wireless communication section for performing communication in a network (300) and a wire communication section to which the new transmission unit (410) can be connected; when the new transmission unit (410) is wire-connected to the management unit (110), it is judged in accordance with the received device type information of the new transmission unit (410), whether or not the new transmission unit (410) is a device having a communication means that can communicate in the network (300); and if the new transmission unit is judged as a device having that type of means, the management unit creates a digital certificate by using a device identifier specific to the new transmission unit (410), and sends the digital certificate to the new transmission unit (410).
