How IPTV Works and What You Need to Know
A clear explanation of how IPTV works — from servers and streaming protocols to buffering, the program guide and what affects picture quality at home.
Key points
- The EPG is the on-screen TV guide in your player app.
- Guide data is downloaded separately and refreshed regularly.
- Wrong times are almost always a device time zone problem.
- QLD, WA and NT don’t observe daylight saving.
What is an EPG?
An EPG (electronic program guide) is the grid on screen that shows what’s on each channel now and later. In an IPTV app it usually lets you scroll ahead, read program descriptions, and jump straight to a channel.
How the guide works
Guide data comes from a separate feed, not from the video stream itself. Your app downloads it, matches each listing to a channel, and converts the times to your device’s local time zone.
Because it is refreshed on a schedule, a newly added program may take a short while to appear. Refreshing the guide in the app settings, or restarting the app, pulls the latest data.
Australian time zones and daylight saving
| State / territory | Standard time | Daylight saving? |
|---|---|---|
| NSW, ACT, Victoria, Tasmania | AEST (UTC+10) | Yes — AEDT (UTC+11) |
| Queensland | AEST (UTC+10) | No |
| South Australia | ACST (UTC+9:30) | Yes — ACDT (UTC+10:30) |
| Northern Territory | ACST (UTC+9:30) | No |
| Western Australia | AWST (UTC+8) | No |
Daylight saving runs from the first Sunday in October to the first Sunday in April in the states that observe it. If your guide is exactly an hour out during that period, your device’s time zone is the cause.
Fixing guide problems
- Set the device’s time zone to your state (not just “GMT+10”) and keep automatic time on.
- Check the player app has no separate time offset set.
- Refresh or reload the guide in the app settings.
- Restart the device.
If the guide is missing for specific channels only, contact support with the channel names.
