A Multiframe Rate Compression-Free Video Recorder for Universal DTV Mastering in High Resolution

David J. Bancroft

A number of proposals have been made for a single universal mastering format for DTV to cater to the multiple distribution formats, both high and standard-definition, now being encountered in this medium. Such a universal format is projected to reduce production costs and increase efficiency. A key element to support such a format has so far been missing: a videotape recorder of sufficient internal bandwidth to perform the basic functions expected of a classic post-production VTR, but at high-definition bit rates, and without recourse to compression. It is equally important that the machine be adaptable in frame rate, to cover both universal mastering and international distribution formats for DTV. It must also record more audio channels than earlier designs, to satisfy DTV's surround sound requirements. This paper describes a new device that satisfies these requirements. Adherence to important SMPTE standards is also covered, together with a development path planned for the recording of images in a pure data form as an alternative to video.
