<p class="MsoNormal">Hello Rodney and All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We had a good meeting with Hugh and James with our GRC media group, who have the hardware encoder from Sandy, and are awaiting an additional piece (or two?) which should be arriving Friday or perhaps Monday of next week. Our plan is to
conduct the testing in their media lab, as Hugh and James have graciously offered to provide their talents on the video side of the tests while we handle the DTN processing. To reiterate, we are planning on the following streaming configurations for the test
points:<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 @ 8 Mbps<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A few important questions remain:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo4">Any priority to the above points, such as start with the highest load and step down from there?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo4">One unknown still is the media source. Walt, were you still sending a camera? GRC may also have equipment available in the ITC studio, but it sounds like we need to check for the
encoder interconnect compatibility with the component yet to arrive. <o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo4">Should we rather utilize a standardized complex test pattern/protocol instead of a random live camera image?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo4">We are getting very close to the end of the month, so am I correct in understanding you need these results for the upcoming CCSDS meeting? And if so, what is your actual deadline
so we can rally around it?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo4">Finally, what kind of verification for test success are you looking for? Are simple bit checks between the source and destination file content after transmitting across a DTN sufficient?
We could perform some post-processing quality metrics, but given the time crunch I don’t know what all we could promise here.<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We’re still very committed to conducting these tests for you, so as soon as the equipment situation can be sorted we can commence the testing.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance for your timeliness.<o:p></o:p></p>
