fault-tolerant memory architecture for storing one hour of D-1 video in real time on long polyimide tapes

Research is under way to fabricate large-area thin-film transistor arrays produced on a thin polyimide substrate. The polyimide substrate is available in long thirty centimeter wide rolls of tape, and lithography hardware is being developed to expose hundreds of meters of this tape with electrically addressable light modulators which can resolve 2 $\mu$m features. A fault-tolerant memory architecture is proposed that is capable of storing one hour of D-1 component digital video (almost 10^12 bits) in real-time, on eight two-hundred meter long tapes. Appropriate error correcting codes and error concealment are proposed to compensate for drop-outs resulting from manufacturing defects so as to yield video images with error rates low enough to survive several generations of copies.
