Re: HDHR3 Prime. How do I troubleshoot pixelation on DRM channel with dark background?

The OOB signal strength doesn't really matter for several reasons: The data it carries is background information like authorizations for the CableCARD and the channel lineup, not anything that would directly impact live viewing except when you're on the phone with the cable provider and they're maki...

Re: HDHR3 Prime. How do I troubleshoot pixelation on DRM channel with dark background?

Assuming it's an encode problem, you should see similar issues on a cable box, though not necessarily identical since the MPEG2 spec allows different decoders to produce different outputs given the same input, and once that output is obtained, it gets fed into other things that might do postprocessi...

Re: HDHR3 Prime. How do I troubleshoot pixelation on DRM channel with dark background?

If it's happening across multiple devices and multiple GPUs, I'd be inclined to blame the cable provider's encoder. Encoders rely on technology called statistical multiplexing to dynamically allocate bits between different services that are carried on the same channel. They monitor the content of al...

Re: ATSC 3.0: Raleigh/Durham

It's probably 1080i. A lot of decoders (including ffmpeg, which is the basis for pretty much every open-source app out there including VLC and Kodi) don't properly support interlaced HEVC video, because outside of the world of broadcast TV, interlaced video is basically dead and buried. And, until A...

Re: Recording 4K HDR via curl/FFMPEG

Even a bottom-end ARM-based NAS can record the 4K channels from Verizon. They're encoded at a somewhat higher data rate than the highest rate HD channels so it might struggle on wifi or other slow networks, but if your setup can record 2 regular HD channels then it is more than fast enough to do a s...

Re: ATSC 3.0: Raleigh/Durham

Ahhh that would explain it.... Though generally speaking I've not had good luck with windows store version of application install (professionally) which is why I tend to shy away from that route. Still begs the question why isn't the version on SD's website newer or better???? Unless they plan to i...

Re: MacBook Air / 20201119 Release

You should get a short recording of the stream, upload it to Google Drive/Dropbox/whatever and send a link to SD's support team so they can look at it and determine if it really is an app problem or if the station is messing something up.

Re: Want to switch to Spectrum cable

All areas that were TWC before the merger are DRM protected on everything except the broadcast channels. I'm pretty sure all of the legacy Charter areas in DFW (most of Tarrant County, Park cities, etc.) are the same way. DRM channels can only be recorded by WMC on Windows 7 or 8.1.

Re: ATSC 3.0: Dallas

The framerate problem isn't intentional as far as I can tell. There's just something somewhere that is dropping frames that shouldn't be. Playback starting seems to take a while because a lot of apps have a 5 second timeout to receive data, and it can take longer than that depending on precisely whe...

Re: "diy" connect heatsink/fan help

The Extend varies the fan voltage depending on the CPU temperature to limit noise. If you're using your own fan you might want to power it separately since the lower voltages might not be enough to spin it up. You might be able to just wire it straight to the power connector since that's 12V.

Re: ATSC 3.0: Dallas

I wish I had a way to see the format being transmitted- I think the framerate might be a little low. Replying to your post from the other thread here since it's a Dallas-specific thing. You are correct, all 3 of the 1080p channels on KSTR are being transmitted at a reduced framerate (49.2's is corr...

Re: Roku changes channels slowly

Roku devices won't start playing until they have whatever they consider enough data buffered. When you're playing pre-recorded video (including "live" web streaming video), there's always enough data on the server to fill the buffer as fast as the data can transfer. When you're watching true live TV...

Re: FiOS without Coax?

There's no way to test it. Data can be active either over ethernet or over MoCA, not both at the same time. And again, TV is always over coax.

Re: HDHomeRun VIEW won't display Cable Channels: HDHR3-CC, Win 7 64bit

All your "cable" channels are going to be DRM protected on Spectrum, so everything you've described is exactly what should be happening.
