a) in the MAC field enter the MAC address of your TV;
b) The "snake" to the right of the MAC field changes the playlist loading method, either you download the playlist and specify (select) the path to it, or you provide a link (URL) to the playlist and the device itself downloads the required playlist from our resource; You can see the playlist link in your personal account Playlists->Links, select the SmartIPTV playlist and click the Copy button, the playlist link for this player looks like this http://tv.team/pl/13/*****/playlist.m3u8 (instead of stars your unique access code (token)); We recommend the second method of loading the playlist, because if there are changes in the list of channels, you will not need to download the playlist again;

Configure the player according to the instructions 5.5 Setting up the ott-play player.
Player M3U IPTV (only for Samsung Tizen and LG WebOS)
https://m3u-ip.tv/
To set up the M3U IPTV player, use the Televizo playlist.
It seems that the archive on the M3U IPTV player only works on the Premium version of the player, which costs 1400 rubles.
ATTENTION! due to the update of the donor application RedBull, on many Samsung TVs, the player ott-play (FOSS and DRM), installed this way, stopped loading. For this reason, it is better to install these players on Samsung TVs via widget (you need a computer/laptop). You download the archive of any player to your computer, unpack it, run the application (file with the extension exe), and follow the instructions that appear on the screen:

Additions and explanations to the instructions:
1) For more details on how to enter the developer menu, you can search on the Internet;
2) the computer and the TV must be on the same local network, i.e. connected to the Internet in the same way - both by cable or both by Wi-Fi;
3) press the buttons in this order: 1-OK-2-OK-3-OK-4-OK-5-OK, i.e., after selecting the numeric button you need to press OK, and the buttons should be pressed quickly, without pauses.
