Video Distribution & Video Conversion
On more complex airborne surveillance aircraft – where a number of video displays or other equipment such as computers, video recorders and microwave links are being used – it is sometimes necessary to provide high quality video distribution inside the aircraft to make sure that the image quality is kept throughout the system and is available to all operators simultaneously.
Tracer Aviation provide both simple and comprehensive distribution solutions to enable complete flexibility in the aircraft without compromising quality.
Our TVD-160 series multiplexer is our most common video amplifier and includes options for producing a quad screen view from any four video sources. Further options include video conversion allowing for a multitude of applications from one simple unit.
The TVD-160 is essentially a comprehensive video matrix allowing up to 14 HD-SDi video inputs to be amplified, distributed or converted to multiple outputs. For example one input can be amplified to anywhere between 2 & 12 outputs. Or, 4 different inputs can be amplified to 3 sets of outputs enabling each of the video sources to be used on multiple screens, datalinks, video recorders etc.
The Quad option on the TVD-160 allows a quad view image to be constructed from 4 live video inputs and the output as a quad to multiple sources. This can be especially useful where an operator wants to record all of his video sources only using a single channel to record them on.
Video & data conversion
In addition to video & data distribution we also supply a number of products to convert different interfaces to standard video or graphic interfaces commonly used on surveillance equipment. Please contact us for your particular requirements.

Weather radar converters, Seaspray radar display
AIS transponder interfaces
STANAG 3350 A/B/C conversion
RGB to VGA and most other common video signal conversions
STANAG 4609 data-streaming NATO digital motion imagery format
Metadata from camera systems
STANAG 4609 is intended to provide common methods for exchange of motion imagery across systems within and among NATO nations. It provides a guidance on uncompressed, compressed, and related motion imagery sampling structures; motion imagery time standards, motion imagery metadata standards, interconnections, and common language descriptions of motion imagery system parameters.
Unmanned Air Systems use two types of KLV encoded metadata. Universal Data Set (UDS) – the 16-byte key, basic encoding rules (BER) formatted length, and the data value is appropriate for applications where bandwidth isn’t a concern. However, transmitting the 16-byte universal key quickly uses up the available bandwidth. UAS airborne platforms use a wireless communications channel where the bandwidth for metadata is limited. Because of the bandwidth disadvantages of using a Universal Data Set, it is more desirable to use a Local Data Set for transmission over a Datalink. Local Data Set can use a 1, 2 or 4-byte key with a 1, 2, 4-byte, or BER encoded length. For more info about KLV use please contact us.
Used in both military and civil applications, KLV allows developers to create applications that receive streaming video coming from UAV platforms, extract the telemetry and other metadata (KLV format, for example EG 0601.X) process it in real time or archive for later retrieval.
