摘要:
A photosensitive medium, such as motion picture film, having digital data in multiple formats and analog audio signals photographically recorded thereon, and a system for photographically recording digital data (preferable including digital audio bits) in multiple formats and optionally also analog audio signals on a medium. Shown is a block diagram of an embodiment of the inventive system which includes a first camera assembly (56, 58) for photographically recording both digital and analog audio signals on a single motion picture film (61) in real time, and also includes a second camera assembly (96) for recording additional data on the same film (61) at a rate slower than a real time rate.
