INSERTION OF WIDE BANDWIDTH VIDEO DATA FOR COMMUNICATIONS FROM RECONNAISSANCE SATELLITES
Abstract
An analysis is presented of design parametersAND DEVELOPMENT OF A BREADBOARD DEVICE TO DEMONSTRATE THE FEASIBILITY OF REAL-TIME ENCODING OF THE ELECTRICAL ANALOGS OF WIDEBAND PICTORIAL DATA. The analog-to-digital conversion technique, along with the peripheral logic and communicating circuitry resulting from this effort, shall be capable of quantizing and coding video signals, with frequency components up to 25 mc, to a precision sufficient for faithful reproduction of reconnaissance photographs. The objective is the determination of the optimum components and techniques for providing a data conversion equipment for the transmission and reception of reconnaissance photographs. The devices to be considered for the realization of this equipment include tunnel diodes, varactor diodes (i.e. snap-on diodes, snap-off diodes) parametric diodes, transistors and other applicable solid-state devices. The three-month study phase is to investigate and analyze the various approaches to high-speed conversion. A detailed breakdown of the advantages and disadvantages of the various techniques is included. (Author)
