MPEG-2/MPEG-4 COFDM NEWS AIRCRAFT TRANSMITTER

Nucomm SkymasterTX (SKTX) is a lightweight, full-featured digital COFDM video downlink transmitter built to address the unique requirements of aircraft downlink operation. The chassis design features either horizontal or vertical ARINC mounting. All of the connections and controls have been located on one side of the unit. This allows the SkymasterTX to be removed from one aircraft and installed in another with ease.

A unique feature of the SkymasterTX is a built-in GPS receiver. This allows aircraft position data to be downlinked to the command center for display on a moving map system. This feature allows rapid location of the aircraft.

The SkymasterTX can operate in a wide variety of bands delivering High Definition and Standard Definition video resolutions. The SkymasterTX can output up to 8W of RF power extending and improving link reliability. The SkymasterTX features COFDM digital modulation. COFDM modulation is unaffected by multipath – unlike single-carrier modulation formats such as FM, CDL or QAM. The SkymasterTX has a built-in H.264 (MPEG-4) and MPEG-2 encoder. MPEG-4 encoding is the latest encoding method. MPEG-4 requires 50% less bit-rate over MPEG-2 improving the reliability of the transmission even more. MPEG-4 also allows for the transmitting of HD video without sacrificing performance.

IMT has taken great care with the design of the internal H.264 encoder. It has been designed with video quality as its cornerstone. The quality of the encoding rivals that of full-featured rack mounted encoders. Switcheable MPEG-2 options makes the transmitter compatible with the legacy installed system, thus protecting your capital investment and extending the life of your legacy infrastructure.

Knowing that security of the video is critical, the SkymasterTX features the latest in AES 128 and 256 encryption. This feature can be enabled or disabled very easily allowing the mode to be selected depending on the mission requirements. To ensure interoperability between vendors we also conform to BCRYPT, a published, non-proprietary standard.The front panel LCD and a Remote Control user interface allow for quick control of preset selection, standby mode, and encryption mode. For advanced functions such as changing frequency plans, AES encryption keys, or unit naming, an easy-to-use administration software package is supplied. Configuration is flexible with 16 or more different presets available.
