Off the top of my head I’d go with one of these: 1080P60 h.265 @ 6 Mbps and 8 Mbps

That’s probably a safe middle ground.

Hi,
I would try out-of-order with a 100ms->1.5 second window, and between 10%-50% percent probability. Additionally, I’d enable duplication for one or more tests. Finally, I’d consider potentially higher numbers of RTP packets->bundle (let’s say 20)

Thanks,
Jeremy

Thank you Joshua,

We held our HDTN team meeting this morning, and have plans to reset our Orin’s tomorrow in a separate facility adjacent to the Netropy.

With a fixed resolution/bit rate at the source we should be able to accommodate these 3 test sets once we get the desired Netropy values.  Sooner is better than later as we need to reallocate this hardware toward our LunaNet and flight testing, and I’d imagine sooner is better for you all as well.

Daniel

Subject: RE: [Sis-mia] [BULK] Re: [EXTERNAL] RE: RTP over DTN streaming tests - preliminary outcomes look good

Hey all, the MIA WG would like to request that our GRC counterparts please complete a few more specific tests.

Setup:
Hardware Encoder<->HDTN<->Netropy<->HDTN<->Hardware Decoder.

Test Sets:
No DTN just RTP over UDP by itself
Single RTP packet per bundle
Five RTP packets per bundle

Within each test please use the netropy out-of-order delivery option set three different ways.

Jeremy, please provide the netropy out-of-order values to use along with the resolution/bit rate to make sure the range you had in mind is covered.

If I missed anything please feel free to correct me or ask for clarification.

Sincerely,
Joshua Deaton

Hello Rodney,

Yes, several of us will be dialing in to discuss the results, do you know which particular block of the day the media group content will be discussed?

Prash just completed all of the bit analysis for the configurations, so we are going to review the results this afternoon.

As well, we are putting together our plans to conduct further tests throughout the summertime.

Regards,
Daniel

I finally have my NASA identity restored. Just in time.
Daniel, all this is good news. New data. Will you or someone from the team be able to join us tomorrow (Tuesday) for our CCSDS MIA meeting to share this data and answer questions? Anyone from the GRC team planning to attend in person?

Subject: [BULK] Re: [Sis-mia] [EXTERNAL] RE: RTP over DTN streaming tests - preliminary outcomes look good

Jeremy,

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.

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.

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.

Regards,
Daniel

Hi,
Looks good! Just to confirm one thing, these were done without induced packet loss/delay, correct?

Thanks,

Subject: [Sis-mia] RTP over DTN streaming tests - preliminary outcomes look good

Hello Rodney and All,

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.

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.

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:

720P30 h.264 @ 2 Mbps
720P60 h.264 @ 4 Mbps
1080P30 h.265 @ 4 Mpbs, 6 Mbps and 8 Mbps
1080P60 h.265 @ 6 Mbps and 8 Mbps
2160P30 h.265 @ 6 Mpbs and 8 Mbps
2160P60 h.265 @ 10, 11, 12, 20 & 30 Mbps

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.

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.

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!

Regards,
Daniel
