 But of course, the more channel information you add, the better. Here's an example of what a full version of a link in a playlist might look like:
 
 ```xml
-#EXTINF:-1 tvg-id="exampletv.us" tvg-name="Example TV" tvg-logo="http://example.com/channel-logo.png" group-title="News",Example TV
+#EXTINF:-1 tvg-id="exampletv.us" tvg-name="Example TV" tvg-language="English" tvg-logo="http://example.com/channel-logo.png" group-title="News",Example TV
 http://example.com/stream.m3u8
 ```
