I'm not sure what this is but it killed my network. I assume it was flooding it, as packet loss was huge, ping times were huge, and I couldn't control the HDHR at all.


It forwards the ATSC 3.0 multicast IP packets onto the LAN (with just the source address and port changed). Probably not a ...

Trip, have you tuned PLP0 via the CLI and set the target to forward and watched either the network rate in Config GUI or monitored via Wireshark to see if there's anything actually on there?

hdhomerun_config xxxxxxxx set /tuner0/channel atsc3:25:0
hdhomerun_config xxxxxxxx set /tuner0/target ...

How are you getting the capture from the HDHR to work?


I'm probably not emulating WNUV close enough. Especially using Transport Streams instead of IP packets. I'll guess the processing path for TS is quite a bit different than IP in the HDHomeRun.

Also, I don't have a universal frame mapper. I ...

I've added CTI to my open source ATSC 3.0 transmitter so that I could run some experiments. I've set up a flow that's similar to the WNUV configuration, but just TDM (not LDM+TDM). But I have used the same parameters for the low bitrate BPS PLP.

The low rate PLP works fine. The data comes out in ...

WNUV could use a 36 (PLP0 and 1) + 1 (PLP16) block HTI configuration and use more cells (and have a higher bitrate on PLP0 and 1) than they are with the CTI configuration.

I think the Sony demodulator is just sensitive to CTI configurations. I bet if they switched to HTI, it would all work. They're not using all the cells in their frame as it is (they're leaving 51257 cells unused), so the "we're able to maintain the efficiencies of CTI" argument is weak.

Some additional info. I can't even test multiple PLPs with CTI on my open source ATSC 3.0 transmitter. When I implemented multiple PLPs with TDM and FDM, I didn't include the CTI interleaver in the frame mapper. There were no multiple PLP test configurations from ATSC with CTI (there are 22 ...

This is just a guess, but I think some of these PLP 16 configurations are out of spec. Specifically, when there are two PLPs in a subframe using the CTI interleaver.

If you look at section 7.1.1 of A/322, it talks about what interleavers can be used. Unless you're using LDM, if there are multiple ...

I may have lost track of this. But usually there a fixed number of days for comments and then a set day for a "ruling". What is the end date if any. That way I can just hibernate until then


The end date for reply comments was June 6, 2025. No date set for a ruling.

The FCC has posted a document that seeks comment on the NAB proposal to sunset ATSC 1.0.

Proceeding 16-142 is a HOT topic on the FCC Filing page. It has 4,102 responses . No other topic has above 2,000 responses, and only 5 (including 16-142) have over 1,000. The responses I've read are almost exclusively opposing DRM, and all are very well written.
