IPTVx supports two type of playlist files - XML and M3U

XML playlists have an advantage as allowed to create web-like description field using CDATA. It can load in-build EPG or simple web page in iframe tag. Also, you may link channel to another playlist using playlist_url tag   [example in red box number 1] Playback of the channel or video file will use the link between stream_url tags [example in the box number 2] Please note, that folders or links to another playlists could be only created in XML file, not in M3U Regarding Samsung supported formats and codecs, please follow this link

  • items - beginning and end of the whole playlist - everything else goes between those tags [required]
  • playlist_name - playlist name [optional]

Example of the extended M3U playlist structure:

#EXTM3U #EXTINF:-1, Channel NAME 1

  • tvg-shift - time shift for EPG (only for Yandex)
  • tvg-logo - link to icon or channel logo
  • tvg-name - channel name (used to parse XMLTV EPG)
An example with channel logo and XMLTV EPG:
