IPTV work on Roku. You can stream IPTV on your Roku-connected device using a technology called screen mirroring that lets you wirelessly share media playing on smaller devices such as Windows, Android, or Apple devices to significant devices such as media protectors or television.  With the mirror or cast option, you can access content on your Roku TV from devices on the same network. In other words, the IPTV player app and Roku TV should use the same Wi-Fi network.
