Sure, it stands to reason that if
I Love Lucy comes on at 9pm and your station clock says 8:55 even though it's really 9:01, your guide will be wrong.
However, ya might realize you were not actually watching
Leave It To Beaver, as the guide said.
I think the PAL is the only CECB which stores the entire matrix of guide info for all channels.
My Channel Master appears to load info for the current station when you tune to it.
(I'll have to look at that more carefully and characterize it properly)
This means you can see what's currently on, as you look at the transparent guide info for what will be on later (12 hours later)
With the PAL (assuming it's like the Dish satellite guide), you can stay on one station, and scroll through the guide in both time and through all stations.
In my market, there are around 25 stations transmitting 50~55 subchannels, so that's a big matrix!
If you were to rely on the Pal guide, it's more likely you would miss a show that was from a TV station with a bad clock.
Given a simpler guide like my Channel Master, you'd get more obvious feedback that something was wrong.
With a simplistic box with Now/Next, you'd always be alerted that the Guide/Time was wrong.
So, whether you wish to take to task my analysis above or not, the punch line is:
- that the more complicated guide (superior?) of the PAL
- in a market with lots of channels
- having stations with varying times
- you are more likely to be led astray
- and miss a show that's listed in your guide.
Because, with less of a guide to rely on, you won't be lulled into a false sense of security.
So, the PAL is a victim of it's own success! -
