About this app

Universal MediaSync turns your mobile or tablet into a second screen perfectly synchronized with your TV.

Discover HbbTV-compatible TVs on your Wi-Fi network and enjoy complementary content - private listening with headphones, audio description, sign language, original version or alternative audio tracks - all perfectly synchronized with what is playing on the big screen.

MAIN FEATURES
• Automatic discovery of compatible TVs on the local network (DIAL/SSDP)
• Private listening: send TV audio to your headphones
• Accessibility tracks: audio description and sign language
• Alternative audio: original version and additional languages
• Precise synchronization with DVB-CSS (CSS-WC + CSS-TS)
• Playback continues with the app in the background
• Available in Catalan, Spanish, Basque, English, German, Italian and French

HOW IT WORKS
1. Connect your mobile to the same Wi-Fi network as your TV.
2. Tune to a channel that offers HbbTV Private Listening / MediaSync.
3. Open the app and choose your TV from the list of detected devices.
4. Choose the audio or video track you want and enjoy it synchronized.

Universal MediaSync is an open source initiative maintained by the HbbTV community: a single companion app for all broadcasters who want to offer second screen experiences, without having to develop one of their own.

Note: Requires an HbbTV compatible TV and a MediaSync enabled channel, both connected to the same Wi-Fi network.
