<p class="MsoNormal">Thank you, Rodney. These test points are very helpful. Nadia and Ethan have been working in the lab, and we are confident we could start testing the H264 @30 with hardware encoding with little change to our current setup. They have also
added scripts to automate the testbed configurations, so making changes will be very straightforward in the future. They have also added the capability to stream content directly from YouTube, in addition to our file transfer and camera streaming capability.
For the H265 points, we will likely need to make some adjustments to the streaming code to accommodate the memory requirements, which should take a few weeks.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There are a couple areas where we could use some assistance.
<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">Since our lab camera tops out at 30fps, we would be interested in borrowing one to accomplish the 60fps test points.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">We are planning on using the Nvidia Jetson Orin for the hardware encoding/decoding. However if there is alternate encoding hardware available we could also use, we would be interested
in that as well for the purpose of comparing results, especially if it was more representative of s/c subsystems.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo3">Up to this point we have not evaluated GOP as a performance metric, do you have any recommended code or process for that?<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you, and we’d be happy to talk through things with you as we endeavor to conduct these tests. As well, beyond these tests we are VERY interested in improving our LunaNet testbed to conduct higher fidelity daily con-ops representative
of Gateway-esque operations. We’d love to learn from you how to improve our testbed to become more relevant and useful to the human spaceflight community, and help answer DTN lunar infusion questions. For these particular test points, if would be great to
eventually publish our performance findings within the context of emulated lunar operations.<o:p></o:p></p>
