Dish is already apparently okay with only having limited guide data on certain channels. Has anyone tried scrolling forward in the guide on the streaming Dish Scapes 2 channel 198? I always hit a wall where beyond a certain point, it will only say "No information available."
That gets to my point about why I feel it is a mistake for Dish to only be concentrating on fixing guide mapping issues with the four major OTA networks, while ignoring all other OTA guide problems. There is overlap onto other OTA channels that need to be fixed. For example, I provided an example earlier where WOIO (Cleveland CBS) OTA guide data is being mirrored on Cleveland's OTA CW affiliate, WUAB. Since the CBS guide data is correct, Dish apparently has no interest in fixing this. However, anyone setting a name-based Search timer for CBS programs might accidentally end up getting WUAB's programming recorded, instead of recording WOIO. I mentioned this particular guide issue in my private conversation with brittanygarden. There has been absolutely no reply since then, so Dish is remaining silent on this particular issue.
www.elliott.org What meta data is missing in what's provided in PSIP?
Preaching to the choir. As I said, I've brought up using PSIP for years on this board, if there's some issue with the satellite delivered data. What I listed were the reasons other posters would tell me why PSIP wouldn't work.
Remember the huge mess years ago, when Dish switched guide data providers (for the satellite-delivered guide info) and stopped using Gracenote? Even if the title of the show, season number and episode number (the data that is actually visible to the user) seemed to remain unchanged, the meta data behind the scenes (what the DVR actually uses to search for and record shows) was different from what it had been before. That caused all kinds of problems with timers that had been created before the guide provider switchover (and even with new timers that were created during the guide provider transition) and the only solution was to completely delete the old timers and start over with all new timers. Then, repeat that process the next time the timers screwed up.
I notice the same type of problem with the guide data on the streaming Vix TV channels that I have been tracking in the thread that I am using as a sort of make-shift uplink report. Whenever I flip through those channels, I notice that the description in the Info banner at the top of the screen will give tomorrow's date for every program. This is not even a case where the incorrect date could be attributed to the guide data using Universal Time (Greenwich Mean Time) as the time zone, instead of a US time zone, since I am flipping through the channels early enough in the evening or afternoon that the time zone difference would still put the shows within the same calendar date.
Don't remember that. But again, WHAT is the Metadata that isn't viewable that causes things to be screwed up? From what I remember, there's various charts and tables showing the PIDs for the audio/video and other assorted elements. I'm pretty sure the station provides guide data (programming charts including descriptions )to a company, and that company then provides the information out to the MVPDs and guide displays (TV Guide, etc). The channels use that same information for their PSIP.
Apparently, the issue started in 2017. Here are some posts from Scott about it at the time:
www.satelliteguys.us www.satelliteguys.us www.satelliteguys.us www.satelliteguys.us When channels were packed some to allow spectrum for ATSC 3.0, the Dish guide for -00 channels is correct but for some the -01 channel program guide for the same station is wrong. Here (Mobile, AL) 44-00 schedule is ok but 44-01 shows the virtual ch 15 NBC station schedule, the programming is correct though!! This caused by the RF freq for the 44-01 and the 15-01 on the same transmitter. ATSC 1.0 can multiplex two 1080i channels on the same transmitter.
Actually ATSC 1.0 you can get up to eight (?) channels, with either 2 or 3 HD from the same frequency.
Here in Chicago, we have one channel that has 9 subchannels, the last one is -10. None of them are HD, even the -01 is SD.
I vaguely remember reading about a company in one city that had like 30 channels that was delivered over two broadcast towers. The channels were mapped so that they were all subchannels on for one channel. There was even a TV guide channel on one of them.'
15 SD channels on each broadcast tower?
After doing some research last night, I realized that that I was confusing the Mhz Network with the Alaska Rural Communications Service.15 SD channels on each broadcast tower?
In the Washington D.C. market, we used to have MHz Networks which specialized in foreign language channels, all of which were SD IIRC. They had 6 channels on their very local (2mi away from me) broadcast tower in Merrifield, VA, and another 6 channels broadcast from a tower southwest of Dale City (name escapes me but it started with "Gold"). They all appeared as subchannels of 30. The MHz Network has subsequently given up both stations in favor of streaming only.
There is ~19.39Mbs that can be split up. Some of that gets reserved for PSIP and headroom and such. I think HD programming is usually 7-10Mbs, SD is anywhere from 1-3. Obviously the less bandwidth the poorer the quality.
USDTV?
en.wikipedia.org Considering that each broadcast tower could be used for multiple stations' broadcast antennas (with each antenna operating at its own separate frequency, obviously) yeah, that is not too surprising.
