Arkham TV

Watch free-to-air digital terrestrial television live and schedule recordings on Ubuntu. Plug a supported AVerMedia AVerTV Volar HD USB tuner into your computer, connect an antenna to the tuner and scan for the channels available in your area.

Hardware and system requirements

Arkham TV supports only the AVerMedia A835 and A835B for DVB-T reception. Ubuntu must recognise the tuner through its DVB driver. The Snap includes playback codecs and is available for 64-bit Intel and AMD computers and ARM64.

Watch and browse

• Scan UHF frequencies, save channel lists for different locations and keep your favourite stations within reach.
• Watch in an Ubuntu desktop window, in full screen or in a floating mini player.
• Browse the TV Guide for programme times and details received over the air. Select a programme to open its channel or schedule a recording.
• Adjust audio sync per channel, choose from ten-band equalizer presets and monitor the live stereo signal with digital or analogue meters.

Record to your computer

Record the current broadcast or schedule one from the TV Guide. Choose or create a destination folder in Settings. Recordings are saved locally as MP4 files with 1080p video and AAC stereo audio. Open, manage and play your recordings from the app. For scheduled recordings, keep Arkham TV open and the computer awake.

English and Spanish

Switch the interface and changelog from the language menu. Channel names and programme descriptions are shown as supplied by the broadcaster.
