Within an IPTV context, the M3U playlist acts as a database for live television streams. Each line in the file corresponds to a specific channel and contains metadata such as the channel name, logo, and group information (e.g., "Sports," "News," "Entertainment").
Modern M3U playlists include #EXTINF tags with group titles (e.g., group-title="Sports" ), logos ( tvg-logo ), and EPG IDs ( tvg-id ). This enables automatic channel sorting and guide population. iptv m3u playlist 2024 2021
