PURPOSE:To obtain a system which does not produce a burst error in a synchronizing pattern by applying interleaving to a synchronizing pattern of a digital data and sending the result from the sending side to the receiving side. CONSTITUTION:A T data from an interleaving section 3 is sent to a decoder 6 through a transmission line 5 having a possibility of burst error and an R data with an error in the T data is outputted from the line 5. The decoder 6 consists of a de-interleaving section 7 forming an FR data, a de-formatter section 8 extracting a synchronizing pattern from the FR data, expanding the result in the unit of one frame and forming (recovering) the reception data, a synchronizing detection section 9 detecting a synchronizing pattern from the R data and outputting a synchronizing detection pulse SF, a synchronizing protection section using the pulse SF to initialize the timing control section 11 and the timing control section 11 controlling the initialized de-interleaving section 7 and the de-formatter section 8. |
