Abstract
A data processing apparatus for synchronized audiovisual output has synchronizing signal bits which are assigned to bits of each sound data, represented by a 16-bit PCM code. A predetermined bit of the assigned bits having the least influence upon the human auditory sense is extracted as a synchronizing signal bit for synchronization of the image data output and sound output.
