Abstract
The concluding phase has been reached for an advanced development task to determine the feasibility of implementing a computer-based system to preprocess digitally encoded block-formatted video data at serial rates up to 250 kilobits per second. A software model has been completed showing that under typical mission conditions the SFOF 360/75 primary computer would be virtually preempted by raw video data at this rate. A High-Rate Telemetry Preprocessor or some similar concept would relieve the primary computer in the Central Processing System of the severe loading that could result from injecting unpreprocessed video information directly into the SFOF 360/75 serial input channels in a real-time or near-realtime environment. A recommendation is made that the technique of video preprocessing be pursued in order to meet the known objectives of future missions.
