The new SkymasterTX is described as a lightweight, full-featured digital COFDM video downlink transmitter designed to address the unique requirements of airborne downlink operations in news helicopters.
With a built-in H.264 (MPEG-4) encoder and optional MPEG-2 encoder, it caters to users with legacy receive systems. Its ability to support both MPEG-2 and MPEG-4 systems protects IMT’s customers’ capital investments in earlier legacy technologies while enabling them to take advantage of the newest MPEG-4 encoding.
MPEG-4 requires a bit rate of 50% less than MPEG-2, improving the reliability of the transmission. MPEG-4 encoding also allows users to transmit high definition video without sacrificing performance.
The airborne downlink transmitter has secure BCRYPT AES 128/256 encryption, which is said to ensure seamless integration and interoperability with any standard-compliant equipment that customers may already have in their inventory. The chassis design features ARINC mounting, with all of the connections and controls located on one side of the unit. This allows users to remove SkymasterTX from one aircraft and install it in another with ease.
