PURPOSE:To prevent errors due to the missetting of a frame address from increasing by setting address data on the basis of the address value of the preceeding frame data and the error check result based upon the error check code that the frame data contains. CONSTITUTION:When reproduced frame data is inputted, a selector circuit 16 which uses the value of reproduced frame address data as the address of a frame and the address value is outputted to a terminal 17 up to frame data which is considered to have no error by decision making as an error check result inputted to a terminal 10. Then, when it is judged that the frame data has no error and the error check result goes down to a low level, the value obtained by adding 1 to the preceeding frame address is preset in a counter 15 and its counted value is selected by the selector circuit 16 and outputted to the terminal 17 to generate an address signal. Consequently, address data updated to a correct frame address value 1 or 2 is obtained. |
