Formatting and Coding the Audio in the DTTR

Kenneth P. Davies

Recording of digital audio in the D-1 format makes use of small sections of the helical tracks and associated channels, which are optimized for recording video data. Appropriate processing and precoding must be used to adapt this channel to the special needs of the audio data for secure, low error-rate reproduction. In addition, the processing must consider the need to interface with digital signal sources, the synchronization requirements between the data streams in the DTTR, and the special functions required for audio editing and other operations. This article discusses in detail the conclusions reached for the D-1 recording format, their implications, and the potential applications. It summarizes the essentials of the longitudinal tracks provided for audio and time code in the D-1 format.
