A data output apparatus is provided. The data output apparatus includes a playback unit and an audio processing unit. The playback unit carries out playback of data at 2× speed from a tape-shaped recording medium, on which has been recorded video data with a field frequency of 59.94 Hz and audio data with a sampling frequency of 48 kHz, by playing back video data in odd-numbered fields and audio data corresponding thereto and video data in even-numbered fields and audio data corresponding thereto in parallel. The audio processing unit writes the audio data corresponding to the odd-numbered fields and the audio data corresponding to the even-numbered fields played back in parallel in the playback unit into a memory, reads out the audio data from the memory at 96 kHz in order of the corresponding fields, and outputs the audio data to dual-link HD-SDI transmitters. |
