    • A navigation system (20) includes a transceiver unit (210), a display unit (250), an input unit (260) and an ECU (230). The transceiver unit (210) transmits a signal for demanding a detection of a navigation path to a path detecting server (10) and then receives path data which represent the navigation path from the path detecting server (10). The display unit (250) outputs the navigation path or a revised navigation path. The ECU (230) conveys data on a departure point and a destination from the input unit (260) to the transceiver unit (210) and transfers the path data from the transceiver unit (210) to the display unit (250). Further, the ECU (270) precalculates deviation-expected paths in the course of driving along the navigation path and selects the revised navigation path among the precalculated deviation-expected paths in case a present position of a mobile object deviates form the navigation path to thereby provide the revised navigation path to the display unit (250).
    • 导航系统(20)包括收发器单元(210),显示单元(250),输入单元(260)和ECU(230)。 收发器单元(210)向路径检测服务器(10)发送要求导航路径的检测信号,然后从路径检测服务器(10)接收表示导航路径的路径数据。 显示单元(250)输出导航路径或经修改的导航路径。 ECU(230)将出发点和目的地的数据从输入单元(260)传送到收发器单元(210),并将路径数据从收发器单元(210)传送到显示单元(250)。 此外,ECU(270)在沿着导航路径行驶的过程中预先计算偏差预期路径,并且在移动对象的当前位置从导航路径偏离的情况下选择预先计算的偏差预期路径中的修正导航路径 提供修改后的导航路径到显示单元(250)。

    • An error correction decoding method and apparatus are provided. The error correction decoding method involves (a) outputting data corresponding to input codewords by referring to a lookup table, which stores data of a predetermined size and corresponding codewords; (b) outputting predetermined error values if there are no matches for the input codewords in the lookup table; (c) forming an error correction block by arraying the data output in step (a) or the error values output in step (b); and (d) performing an error correction decoding process, without allowing codes constituting the error correction block to exchange erasure information with one another, by referring to locations of the error values in the error correction block and the number of errors in the error correction block.
    • 提供了一种纠错解码方法和装置。 纠错解码方法包括:(a)通过参考存储预定大小的数据和对应码字的查找表来输出与输入码字对应的数据; (b)如果查找表中的输入码字没有匹配,则输出预定的误差值; (c)通过排列步骤(a)中输出的数据或步骤(b)中输出的误差值来形成纠错块; 和(d)执行纠错解码处理,而不需要构成纠错块的代码通过参考错误校正块中的错误值的位置和纠错块中的错误数量来彼此交换擦除信息 。

    • The present invention relates to method and apparatus of converting a series of data words into modulated signals. This method generates for each data word a number of intermediate sequences by combining mutually different digital words with that data word, scrambles these intermediate sequences, translates each scrambled sequence into a (d,k) constrained sequence, detects running digital sum (RDS) every bit for each translated (d,k) constrained sequence while counting sign changes of each RDS, selects one sequence of which RDS changes most in sign among the (d,k) constrained sequences after discarding every sequence of which maximum value of RDS is beyond a preset threshold, and records the selected sequence onto a recordable medium such as an optical disk or a magneto-optical disk. The present invention can suppress DC component more remarkably in case that a sequence becomes longer.
    • 本发明涉及将一系列数据字转换为调制信号的方法和装置。 该方法通过将相互不同的数字字与该数据字组合,为每个数据字生成多个中间序列,对这些中间序列进行加扰,将每个加扰序列转换为(d,k)约束序列,每个检测运行数字和(RDS) 在计算每个RDS的符号变化的同时,对于每个翻译的(d,k)约束序列,选择在(D,k)约束序列中RDS变化最大的一个序列,在丢弃RDS的最大值之后的每个序列超过 预设的阈值,并将选择的序列记录到诸如光盘或磁光盘的可记录介质上。 本发明可以在序列变长的情况下更明显地抑制DC分量。
