Do you supply the songs?
No. AktivKTV plays a library you already own or license yourself. That
keeps you in control of your catalogue, but it does mean the app is
no use until you have karaoke video files to point it at.
Can I use YouTube in my bar?
The app can play a YouTube link, and that is fine at home. A venue
playing YouTube to paying customers is public commercial use, which
YouTube's terms do not cover and for which no venue licence is sold.
For a business, your own library is the licensable route.
What do guests need to install?
Nothing. They scan the card and a web page opens. It works on any
phone with a browser.
Does it need internet?
No. Guests join the venue's Wi-Fi, or the tablet's own hotspot when
you are portable. One thing to check at each site: guest Wi-Fi
sometimes has client isolation switched on, which stops phones
reaching the screen. It has to be off.
What file formats play?
MP4 with H.264 video and AAC audio is the safe combination on every
device. The server includes tools that check a library and convert
anything that would fail — including files that play silently on a TV
box because their audio is in a format it cannot decode.
What hardware do I need?
For a venue: a small PC for the library, and an Android TV box per
screen. For portable: an Android phone or tablet, Android 10 or newer,
with room for your songs — around 10 GB per thousand.
