As Ethernet based networks have become the dominant choice for Flight Test Instrumentation
(FTI) network applications, it is also clear that Ethernet based camera integration and applications
have yet to become more wide spread for system level design and integration. A significant
customer base utilizes either separate video compression systems or even just stand-a-lone gopro
cameras for recording purposes in an unsynchronized ways. The use of uncompressed high
definition (HD) video from GigE Vision Ethernet cameras for flight test applications is a
significant issue in managing the large volumes of data produced by the cameras and forwarding
them to any 1000BASE-T(x) switch port without packet loss and significant delays. Of course an
easy approach to overcome this issue would be to just increase the network bandwidth from
1000BASE-T(x) to 10GBASE-SR, but most FTI systems just moved to 1000BASE-T(x) in the
past years and therefore changing the overall system hardware is cost prohibited. One concern
has been the use of compression algorithms to reduce the required video bandwidth, with the
negative side effect that the image quality reduces and end-to-end latency increases, which is not
acceptable for some applications. Further, it is important that data from cameras is available to a
number of different multicast consumers within the FTI network, for example workstations,
recorders and telemetry systems. These video data stream also require synchronization so that
they can be analyzed in post processing.
