     Title: Sentinel - QHD Runway camera recording

Camera imagery of airfields and their control zones, streamed to Air Traffic Control Units to be overlaid with fine detailed graphics and text, is becoming a widespread technology, but until now the recording of this data has been a costly and storage intensive endeavour with only moderate performance.

 

Thruput have long supported a research programme seeking to optimize the recording technology for this type of data, and in the last weeks we have had a breakthrough, that is achieving astonishing results.

 

Thruput have been able to tune a standard Sentinel DP1.2 so it captures streaming camera data, while still maintaining true lossless capture of the overlaid vector graphics. Most important of all, standard zipping tools are able to keep pace with the recording process and perform true lossless compression of these files so they are practical sizes to work with.

Thruput have long supported a research programme seeking to optimize the recording technology for this type of data, and in the last few weeks we have had a breakthrough, that is achieving astonishing results.

Thruput have been able to tune a standard Sentinel DP1.2 so it captures streaming camera data, while still maintaining true lossless capture of the overlaid vector graphics. Most important of all, standard zipping tools are able to keep pace with the recording process and perform true lossless compression of these files so they are practical sizes to work with.

A comparison for the same 60 Hz 3840 x 2160 runway camera data recorded in our RMV format and by an H265 recorder is shown below.


Compared to the H265 solution, Sentinel is achieving better than 400:1 reduction in storage, at a higher frame rate and with perfect fidelity to the original data. The existing features of multi-channel replay and cross channel syncronistation with audio or data are all functioning normally.

Ths is a signifcant advance in afordability and performance that makes possible effective support for CAA CAP 670 and ICAO annex 10 requirements.
