Freeview Play will land next month, with Panasonic's TVs first in line.
Owners of Panasonic's Viera TVs that run the Firefox operating system (the CX680, CX700, CX730, CX802 and CR852 models) will be able to download a software update to get the service.
Freeview Play is next-gen Freeview. Like YouView, it brings together linear digital terrestrial TV channels with catch-up and on-demand.
For example, instead of launching BBC iPlayer as a separate app, you can just scroll back in time on BBC channels on the electronic programme guide and select a show to watch.
BBC iPlayer, ITV Player, All 4 and Demand 5 will be available at launch, with more to follow.
"We're really excited about this launch because, as the Freeview Play launch partner, we can deliver a wider range of excellent programming with the best possible picture quality," said Andrew Denham, managing director of Panasonic UK.
"September and October are big months for TV, so it is fantastic that our customers will be the first to have all these superb on-demand channels just in time for 'Strictly Come Dancing' and the 'Great British Bake Off' final!"
Humax, Manhattan and Vestel will also support Freeview Play in future.
