    • A circuit which recovers a synchronization code, and a method thereof. Where a synchronization code is not detected from an incoming bitstream, a plurality of synchronization code recovery candidate patterns are compared with an original synchronization pattern, and location data to produce an optimal synchronization pattern is determined and generated on the basis of a result of the comparison. The synchronization code is recovered to a location corresponding to the location data. Alternatively, where a synchronization code is not detected from an incoming bitstream, a plurality of synchronization code recovery candidate patterns are error-corrected, and location data to produce an optimal synchronization pattern is determined and generated on the basis of a result of the error correction. The synchronization code is recovered to a location corresponding to the location data. Accordingly, a damaged synchronization code can be recovered by inserting a synchronization code to a more accurate location, further increasing the reliability of data.
    • 恢复同步码的电路及其方法。 在没有从输入比特流检测到同步代码的情况下,将多个同步码恢复候选模式与原始同步模式进行比较,并且基于比较结果来确定和生成用于产生最佳同步模式的位置数据 。 将同步代码恢复到与位置​​数据相对应的位置。 或者,在不从输入比特流检测到同步代码的情况下,多个同步码恢复候选模式被纠错,并且基于纠错的结果来确定和生成产生最佳同步模式的位置数据 。 将同步代码恢复到与位置​​数据相对应的位置。 因此,可以通过将同步码插入更准确的位置来进一步增加数据的可靠性来恢复损坏的同步码。
