AbstractTelevision signals have been digitally transmitted for telemetry applications for several years. Reasons for digital transmission include the need for encryption, bandwidth compression, and the efficiency of time division multiplex. All digital coding techniques which have been employed to date, for video telemetry, are based on intraframe technology. In this case each TV frame is coded independently of the previous frames. In most video telemetry scenes there is a high degree of correlation between adjacent TV frames, and an interframe coding system which compresses the signal by reducing this frame-to-frame redundancy should be effective. This paper explores the potential advantages of interframe coding for video telemetry. Since this high level of compression typically causes the transmitted signal to be more sensitive to data link errors, the paper also examines advanced error control techniques.
