NHK's unexpected SoftBank TV tuner allows you to watch TV even if the tuner and the iPad on the display are separated.
If you look at the WI-FI at home, it's just a separate tuner TV, but you can call the tuner at home and watch the TV even in the WI-FI environment on the go.
When I asked NHK if I had a tuner in my parents' house and an iPad in my apartment, I wasn't expecting such a device.
Iranechkei can't be welded, but what about this tuner?
By the way, although it is a Softbank tuner, it can be used without a contract.
The app is also free, but Android has few compatible models.
Professor Mori Ah T is a villain, but since he has a contract with NHK, there is no particular problem with using this.
