Using Pro:idiom DRM Streams on LG Devices

Users can now display IPTV channels with Pro:idiom DRM encryptions on LG webOS SoC (System-on-Chip) devices running Appspace App.


  • LG devices running webOS 4.0 and above
  • Supported protocols:
    • Realtime streaming protocol (RTSP) – Pro:Idiom + RTSP
    • Hypertext Transfer Protocol (HTTP) – Pro:Idiom + HTTP
    • User Datagram Protocol (UDP) – Pro:Idiom + UDP.
The DRM (Pro:idiom) encryption does not support the Real-time Transport Protocol (RTP) protocol
