ABSTRACT OF THE DISCLOSURE A system for reproducing digital audio data from a recording medium on which segments of digital audio data are recorded with video data, 3 segments of the digital audio data corresponding to 1 field of the video data, each segment including plural samples of the digital audio data, the number of the samples in each fields out of 5 fields being different from that of remaining 1 field, and each segment further including identification data indicating field numbers I through 3 to which each segment belongs, comprising means for detecting the identification data in each segment or-the digital audio data, means for detecting an error in the identification data, means for deriving numbering data 1 through 15 (= 3 x 5) from the identification data, the numbering data indicating the phase of each segment in a set of periods of the 5 fields, counter means into which the numbering data derived from the identification data is loaded when no error is detected in the identification data and which counts a clock signal when an error is detected in the identification data, the clock signal having a period corresponding to 1 segment, and means for reconstructing the digital audio data according to the output of the counter means.
