It's heard to do a search for this answer because these terms show up often in other contexts, so if it is out there, my apologies. I'm trying to figure out the difference between each of these terms/labels in an m3u, and mistakes to avoid (such as duplicating them across sources). (This came up for me in trying to trouble shoot my "jump to top of guide" glitch on the Apple TV (this glitch doesn't happen on Android TV for me in limited testing).
Here's what I think I've figured out so far:
- tvg-chno is the channel number as I want it to appear in Channels. This can be duplicated (I think?) across sources, so long as they are in fact the same channel in each source.
- tvc-guide-stationid is the Gracenote station ID, for purposes of downloading guide data. These should be the same across sources, for the same channel, if you want your sources to rollover from one to the next when one is in use (I think?)
Are the above two points correct? And I'm not sure of the significance of the other two. Any other things to be cautious about? Thank you.
