An EPG is schedule data supplied by the service or imported separately, then interpreted by the player.
Step 1: prepare
Write down the device, player version, connection and what you want to measure for IPTV EPG and TV guide. An EPG is schedule data supplied by the service or imported separately, then interpreted by the player.
Step 2: run the check
Check the current time zone and whether the player successfully refreshed its guide. Test a second example and make one controlled change at a time so you can tell what made a difference.
Step 3: decide
Record the result, full price and support response. Assuming an empty guide means the video stream is down. Repeat the test if the comparison was made on a different network or time of day.
What to do next
Open the relevant brand page and check the original supplier information before ordering. For a technical issue, write down the device, player, connection and one reproducible example. For a price question, ask for the full charge in the currency you will pay.
