The Digital Television Tape Recorder — Audio and Data Recording Aspects

Kenneth P. Davies

For some users, the digital television tape recorder (DTTR) is most attractive for reasons of its video performance, particularly in regard to numbers of generations without significant impairment addition. Others, however, recognize that the largest improvement in performance when going to these new machines from current analog-based, C-format machines will be in the quality, flexibility and quantity of the audio recording tracks. The recording format proposed offers the potential of: * 120 dB dynamic range. * 20 kHz bandwidth. * Very low distortion. * Negligible timing errors such as flutter, wow and dispersion. * Four channels individually editable in sample, track, field or frame increments. * Twenty or more generations without impairment build-up if digital processing is employed. * Graceful reduction of performance, at worst, in the event of catastrophic failures such as heads clogging, tape scratches etc.
