Piren is a fully-featured channel-list manager for Internet TV, with an integrated player which currently supports M3U8/HLS streams.
Once registered, you have granted access to a personal URL for your own M3U playlist, that you can use from everywhere, with any compatible set-to-box or IPTV software, or with any compatible app for your Apple TV or smart television.
Pirens extremely easy-to-use interface allows you to add, edit, delete and reorder any of your TV channels or video streams in no time.
