The Digital Television Tape Recorder — Audio and Data Recording Aspects
The digital television tape recorder (DTTR) is expected to achieve very high video performance. Audio performance must be comparable while offering far greater operational facilities and flexibility. The designer of the audio systems for the DTTR is constrained in many directions — user needs, specified performance, relationships to the video channel, and interconnection to a completely digital production facility — while having to be conservative in terms of circuit complexity and reliability. There are few precedents to rely on, and the specification of the audio and data formats has produced novel ideas and concepts heretofore unknown in television technology. This article outlines requirements and constraints, proposes a format that meets them, and offers several new features not currently found in analog recording.
