dropouts and pixelation with new quattro

Postby inline_phil » Thu Oct 18, 2018 2:13 pm

Have a new quattro, Model: HDHR5-4US, Device ID: 1074D2A3, Firmware: 20180817.

Have followed others with this same issue so I have already power cycled, assured current software, and re-scanned channels from the "Digital Antenna" tab in the setup app. I have also re-scanned channels [Detect Channels] from the admin login on the HDHomerun TV [from its IP address].

Tuner status shows: Virtual Channel 8.1 WFLA HD
Frequency 177.000 MHz
Program Number 3
Modulation Lock 8vsb
Signal Strength 95%
Signal Quality 100%
Symbol Quality 100%
Streaming Rate 10.044 Mbps
Resource Lock 192.168.1.103

Problem occurs most frequently when a scene quickly changes and there is motion in the new scene. Pixelation appears where the motion starts and follows the motion.

HELP!!!

Is it specific to that one channel?

Are you using something with NVIDIA graphics?

Channel 8 shown is the worst but it also appears on channel 3.

Signal level was low [about 74%] so I bought an antenna preamp and mounted it just below the antenna. Made no difference in dropouts but it did improve the signal strength to 95-97%.

Dropouts appear on my PC and on the TV. Yes, it has an NVIDIA GeForce GTX 1060 graphics card on the PC.

Also using an NVIDIA Shield to the Samsung TV.

Do you have any devices that don't have NVIDIA that you can compare to? There's an issue with NVIDIA decoding on certain streams that we have encountered before and reported to NVIDIA.

No I do not. Same dropouts/pixelation on my TV and my PC on these channels. Streaming from my NAS. Recordings/live show the same results.

I thought the HD HomeRun TV had an HDMI output but I was wrong. Cannot test it by switching HDMI cables.

Thoughts?

Watching the NASCAR Xfinity race recorded earlier today. I believe your suspicions about the NVIDIA Shield TV is spot on. Here is what I've found:

Watching the TV [WD NAS > HD HomeRun Quattro > NVIDIA Shield TV > OPPO UDP-205 > Samsung TV] all hard-wired ethernet is pixelating terribly, and not just when scenes change but definitely a motion-related issue. Have a video I can send you if you need it.

Watching from my cell phone [WD NAS > HD HomeRun Quattro > MOTO G5+] via wireless connection is fine.

So, looks like NVIDIA is having an issue with the Shield driver again.

What's the next step?

Wait and hope NVIDIA fixes it. We've got a sample of an affected station and have confirmed that it plays properly when not using the NVIDIA decoder, but has issues when using the NVIDIA decoder (including using the builtin player on the Shield). We've sent it to NVIDIA and they responded that they believe it's part of an issue they're already aware of, but were sending it to their engineering team for further review. Haven't heard anything more since then.
