This document was prepared by the Range Commanders Council RCC frequency Management Group FMG in response to RCC task FM-4, Flight Test Video Encryption System. It is intended to identify a common, recommended frequency band for the operation of range flight test digitizedcompressed video systems. In the early 1980s, the National Security Agency NSA recommended that all test range communications transmissions be secured. At the time, all range flight test video transmissions were made using nonencrypted conventional analog video systems. To use standard NSA encryptors, it became necessary to digitize and compress these analog video signals. By the late 1980s, it became obvious that a standard digitizedcompressed video system, operating in a common portion of the frequency spectrum, needed to be developed. This task was initiated to determine the common frequency spectrum to be used by this digitizedcompressed video system.
