Abstract: In a time correcting apparatus, a signal including time codes is sampled to generate a bit sequence of input TCO data. A prognostic TCO data generating unit 33 generates a bit sequence of prognostic TCO data based on a current time calculated by a time calculating circuit 17. An error number calculating unit 34 compares bits of the input TCO data with bits of the prognostic TCO data to count the number of discrepancy, thereby calculating the number of errors, and shifts bits of the prognostic TCO data to generate new TCO data and compares bits of the new TCO data with bits of the input TCO data to calculate the number of errors. A judging unit 35 judges if the number of errors is valid. When the number of errors is valid, a time correcting unit 36 calculates a time difference of the calculated current time based on the number of shifting bits, as much as which number of shifting bits the prognostic TCO data has been shifted to calculate such valid number of errors.

Abstract: In a jitter correction method and circuit, combination data combined by adding, to referenced data, an end bit of data 1 clock prior to and a head bit of data 1 clock subsequent to the referenced data is sequentially generated. Each bit of the combination data is sequentially referred. When a change between a referenced bit and a bit directly adjoining the referenced bit is detected, and when a number of references reaches a multiplication number of the oversampling and a change between at least three adjoining bits including the referenced bit is not detected, change position display data regarding the directly adjoining bit as a change bit of the referenced data is generated and the number of references is initialized. When the change is not detected and the number of references does not reach the multiplication number, the number of references is incremented.
