PURPOSE:To renew a reception frame time axis to a region where various timing signals and control signals do not exist by generating reception frame time axis information corresponding to a reception position of a frame synchronizing code. CONSTITUTION:Frame synchronizing code reception position information (c) is outputted to a frame synchronizing code position error detection circuit 12. A variable delay circuit 13 inputs a timing signal (g) preceding by A bits from the end of a frame, gives a delay commanded by detection position error information (d) to the timing signal (g) and a signal indicating the end position of the frame is transmitted to a reception time axis information generating circuit 14 as a reception time axis renewal timing signal (e) to a reception time axis information generating circuit 14. The reception time axis information generating circuit 14 is reset at the end position of the frame corresponding to the position commanded by the reception time axis renewal timing signal (e), that is, the end position of the frame. Thus, the reception time axis information is confirmed and outputted without giving any hindrance to the reception data processing. |
