<p class="MsoNormal">Jeremy,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Yes, that is correct. This particular battery of tests were done in more controlled conditions, as a way to evaluate our HDTN streaming implementation across the range of video configurations.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Concurrently in another facility we have been running a separate experiment streaming a single camera feed 24/7 across a LunaNet HDTN scenario. Over there we do things such as induce delays, change contact plans, reroute, etc to evaluate
performance more at a network systems level. Those more complex scenarios are the ones we plan to upscale to our field demonstrations from May-July.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Working with the video teams on this has been really educational for us, and I know will greatly inform our upcoming space networking tests. We’ve also been able to recently procure some 4K camera equipment and processors with hardware
decoders which we can incorporate into the flight tests to increase their fidelity. Right now we are working on tying our delay/network emulator box into the field tests so we can conduct such things live with the flight test for LCRD and such.<o:p></o:p></p>

<p class="MsoNormal">Hello Rodney and All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Wanted to give you a preliminary status update. We had a lot of help getting things going, which we greatly appreciate, so I am including some extra folks in the cc.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Firstly thanks Walt, Beth and Sandy for hooking us up with the gear to conduct the tests. Hugh, Jim and Mike offered huge assistance in configuring all the equipment and keeping organized with hitting the test points.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We used the available camera in the video lab and supporting equipment, imaged an oscillating fan with streamers and shadows for some dynamics, and swapped things out as necessary to complete the following configurations across our DTN
nodes running the media streaming application:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">720P30 h.264 @ 2 Mbps<o:p></o:p></p>
<p class="MsoNormal">720P60 h.264 @ 4 Mbps<o:p></o:p></p>
<p class="MsoNormal">1080P30 h.265 @ 4 Mpbs, 6 Mbps and 8 Mbps<o:p></o:p></p>
<p class="MsoNormal">1080P60 h.265 @ 6 Mbps and 8 Mbps<o:p></o:p></p>
<p class="MsoNormal">2160P30 h.265 @ 6 Mpbs and 8 Mbps<o:p></o:p></p>
<p class="MsoNormal">2160P60 h.265 @ 10, 11, 12, 20 & 30 Mbps<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The hardware encoder had some trouble getting down to 8 Mbps, I think it was hovering more around 9.7, so we took some extra data points in the vicinity. As things wrapped up today, each of these test points successfully passed the visual
inspections, with the exception of 2 ‘bonus’ points we took with the encoders cranked up to 20 & 30 Mbps. These were done as a curiosity, just to drive our system harder to see it degrade, and we did start to finally observe some blocking and dropped frames
at those extreme cases, but for all the ‘in-bound’ configurations everything looked great! I think we’re ready to go flying.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have copies of all the source and destination media files from the data bundles traversing through the DTN network. Prash is going to now start comparing them more objectively, starting with bitwise checks. I don’t know how much we
are going to be able to get done before your CCSDS briefing which I believe is on Tuesday, but we’ll keep moving forward and keep you apprised. Looking longer term, we would like to do some PSNR, SSIM and VMAF evaluations, combine these results with the field
testing we’ll be performing this summer with the ISS and NASA aircraft laser links, and properly publish the results. When we get to that phase I’ll be reaching out to everyone for proper attribution and such as we pull together the paper.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks to everyone for pitching in! And thanks to Tad, Prash, Nadia and Shaun for supporting on the HDTN side. Have a great weekend, all!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
