Re: ATSC 3.0: Tampa
Does this mean we won't have real 4K broadcast for another 5 years? I bought this solely for the 4K broadcast, even the local news in 4K is fine (understanbly big 4 commercial network will stick with 1080/60i + 720/60p for a while It means no one knows if or when we'll ever have 4K available via br...

Re: ATSC 3.0 Portland: QUATRO 4K
Keep in mind that ATSC 3 doesn't use transport streams, and the ones you do get from the HDHomeRun are being generated on the fly so that ATSC 3 broadcasts can be received by apps that haven't been updated to support ATSC 3 (i.e. literally everything). You can use the HTTP source in TSReader to tune...

Re: No Tuners Available - Getting More Common But not True
Stream closed would tend to indicate that something interfered with communications between the DVR and the device. What do the device logs show at that time?

Re: What can you do with the hardware without a subscription?
AFAIK EyeTV hasn't supported the HDHomeRun since version 3.6.9 or something like that, so upgrading to 4 will definitely be much worse since it won't work at all.

Re: No Tuners Available - Getting More Common But not True
You need to post more of the log from around that time to get an answer. "no tuners available" has a lot of potential causes. All tuners being in use is one of them, but if it tries to tune and the station is off-air, or the signal is bad enough that the tuner can't lock it well enough to decode, or...

Re: Roku TV issues
Roku's video player sucks and can't play most cable channels.

Re: ATSC 3 PQ improvement ?
It would seem that sending progressive would be the safe thing to do for now, anyway. Obviously though, from the discussions in other threads here, not all broadcasters are taking the safe (smart?) route. On the other hand, it's probably better that some are going with 1080i during this experimenta...

Re: ATSC 3 PQ improvement ?
In the Portland market, all 1080i stations are upconverting to 1080p for ATSC 3.0 (HEVC doesn't support interlaced encoding). There is an option in the standard to provide metadata to indicate the content is interlaced, but as far as I know the encoders we're using here aren't sending that info. HE...

Re: Channel Detection Scan (channels 2-6)
The problem is that since wavelength is calculated by dividing by the frequency, the lower the frequency goes (especially below 300MHz), the more the wavelength changes from one channel to the next. Bowties are effective for UHF because the wavelength doesn't change very much across the band. The wa...

Re: ATSC 3.0: Tampa
The whole point of the original digital transition was to sell 52-69 to the cell phone companies and give the government more money to spend. The ATSC tuner requirement happened as a way to facilitate that. The funding for the coupon program came out of the revenues from the selloff, and it was stru...

Re: ATSC 3 PQ improvement ?
The ATSC 3 channels in Dallas, when they're up (which is less often than when they aren't), are running at reduced framerate and even without the full complement of frames to encode they still look worse than the legacy ATSC broadcasts.

Re: Channel Detection Scan (channels 2-6)
A bowtie style design would still need to be huge to pick up low VHF. https://www.changpuak.ch/electronics/Butterfly-Antenna-Designer.php will calculate the numbers, and at 79MHz for channel 5 it wants 1.5m long legs, and the antenna overall ends up about 3m*1m. Better off with a (folded) dipole. A ...

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...
