Recording: what is and is not supported
- Recordings are stored on an external USB drive. A microSD card cannot be used for recording or storage.
- The box records one programme at a time. Simultaneous recordings are not supported.
- Some DRM-encrypted ATSC 3.0 broadcasts carry additional restrictions on recording and playback.
- Pause and time-shift depend on the speed of your drive. A USB 3.0 flash drive or an external SSD is recommended, because a slower drive can cause playback to skip on high-bitrate ATSC 3.0 channels.
ADTH NextGen TV USB tuner
| Feature | Supported | What it needs |
| ATSC 1.0 channels | Yes | Host device must decode MPEG-2 and AC-3 |
| ATSC 3.0 (NextGen TV) channels | Yes | Host device must decode HEVC and Dolby AC-4 |
| Encrypted (DRM) channels | Yes | Internet connection. Whether a particular station authorises playback is set by the broadcaster |
| HDR | Passed through, on capable devices | The station must broadcast in HDR and your device must handle the ATSC 3.0 HDR format. On devices known to handle it badly, the app converts to SDR on purpose so the picture stays correct. The Google TV Streamer is one of those. |
| Host devices | Android TV, Google TV, Fire OS | A working USB port with USB OTG support, and the ADTH TV app |
For results on specific models, see tested and supported devices. If your device is not listed, it has probably not been tested yet rather than being unsupported, and the compatibility check is the quickest way to find out.
