摘要： A reproducing device, error correcting device, and error correcting method which can avoid useless power consumption without sacrificing the reliability of data. The reproducing device is provided with a first error correcting means which detects and corrects the error of data which have been corrected in error and encoded with a product code by using an internal code, a second error correcting means which detects and corrects the error of the data by using an external code, a condition discriminating means which discriminates whether or not the data meet a prescribed condition, and a control means which inhibits the error detection and error correction using the external code in accordance with the discriminated result of the condition discriminating means. Since the error detection and error correction using the external code are inhibited only when the data meet the prescribed condition by discriminating whether or not the data meet the condition, the power consumption by the error detection and error correction using the external code can be saved when the error detection and error correction using only the internal code are sufficient to obtain sufficiently reliable data.
摘要翻译：可以在不牺牲数据可靠性的情况下避免无用的功耗的再现装置，纠错装置和纠错方法。再现装置设置有第一纠错装置，其通过使用内部代码来检测和校正已经被错误地校正并且被编码的产品代码的数据的错误;第二错误校正装置，其检测和校正错误，通过使用外部码的数据，鉴别数据是否符合规定条件的条件判别装置，以及根据条件识别装置的判别结果禁止使用外部码的错误检测和纠错的控制装置。由于使用外部代码的错误检测和纠错仅在数据符合规定条件的情况下被判定为是否满足条件时被禁止，所以可以节省通过使用外部代码的错误检测和纠错的功耗，仅使用内部代码的错误检测和纠错就足以获得足够可靠的数据。

摘要： A method and device for correcting errors in digital data suitable for high-density recording to a Hi-Vision VTR, etc. A block external-code ECC circuit (4A) adds more than 1/N of external codes of every block to digital data, for example, a video signal to be recorded when the number of tracks per field is N, and a block internal-code decoding circuit (14A) adds internal codes to the video signal in the form of codes representing the products of the external codes by the internal codes, thus generating error-correcting codes structured doubly. The external codes in these error-correcting codes are recorded distributedly on N tracks for one field on a video tape (1).
