An EPG is schedule data supplied by the service or imported separately, then interpreted by the player.
Use one test sheet
Put candidate services side by side for IPTV EPG and TV guide. An EPG is schedule data supplied by the service or imported separately, then interpreted by the player. Use the same device, connection, test time and definition of success.
Compare evidence
Check the current time zone and whether the player successfully refreshed its guide. Record the supplier link, total period cost, player charge and renewal route for each candidate.
Choose deliberately
Assuming an empty guide means the video stream is down. If one service has an unknown condition, treat it as unknown until the supplier confirms it rather than awarding it the best score.
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.
