ABSTRACT:
In an apparatus for transmitting digital data which includes information data and synchronous data having a plural-byte code arranged in a plural-byte code of the information data; the top bit position of the sync code is predicted by converting the transmitted digital data into parallel data at a desired timing and then comparing each byte of the parallel data with a particular byte of the sync code; and the sync code is detected in the transmitted digital data by first extracting, from the parallel data, a length corresponding to the plural-byte sync code starting from the predicted top bit position of the sync code and then comparing the extracted parallel data with the sync code.
