Abstract
During both MVM’°73 encounters, real-time TV data at 117.6 kilobits/s will be transmitted from DSS 14 to the Space Flight Operations Facility (SFOF) along a 230.4-kilobits/s supergroup line. The reliability of this link is largely an unknown parameter, but previous experience with similar data channels suggests that random (nonbursty) bit errors may occur at rates between 1 in 10' and 1 in 10° bits. The original design of the word formatter necessitated by the discrepancy between the source and ground transmission rates is shown to be inadequate to guarantee acceptable reception of the TV data at the SFOF. An alternative formatter design is described, which alleviates this problem with minimum cost changes from the original system.
