A Very High Bit Rate Image Data Recorder

A number of applications for high-resolution image capture and processing operate with data derived directly from the colorimetric values of the image source rather than with video signals. One purpose is to accommodate more flexibly the greater variations in spatial resolution, color gamut, transfer characteristic and aspect ratio that can occur when the original is film-based, rather than video camera based. Another is to allow universal mastering that can deliver the finished content to a variety of destinations-conventional cinema, digital cinema, DVD and broadcast video-without the need for re-mastering each one. — Several products now exist to support operations in this desirable data form, including disk-based storage of very high speed and capacity, but what has been missing so far has been a suitable mass storage backup device: data representing high-resolution moving images is extremely voluminous, and the limited capacity and transfer rate of most tape-based storage devices has until now caused backup and restore operations to be a major bottleneck in the workflow.
