Thus, the operation of the MPEG encoder 4 is stopped and compressing processing to digital signals is not performed until the finish of the CM. With the detection of the finish of the CM, conversion to the digital signal of the compressing processing of a normal MPEG 2 form is restarted. The digital signal converted after removing the CM or the digital signal including the CM, which is selected from the kind information of the CM constituted to be the layer of the flag and converted are recorded in a recording medium 6.
