HAT TV Tuner for Raspberry Pi Official

The TV HAT allows you to receive and decode digital television (DTT) streams on your Raspberry Pi via its built-in DVB-T2 tuner. Then you can watch these streams on any computer connected to the same network as the Pi.

It is recommended to use it with a Raspberry Pi 2, 3, 3+ or higher for performance.

The recommended software to decode the streams (called multiplexes) and display the content is called TVHeadend. You will find the instructions below to configure it. The HAT TV can decode one multiplex at a time and each multiplex can contain multiple channels.

The content can be viewed on the Raspberry Pi to which the HAT TV is connected or remotely via another device on the same network.

Digital Video Broadcast (DVB) is a widely adopted standard for the transmission of television programs. The countries that have adopted the DVB standard are available here; https://www.dvb.org/resources/public/images/site/dvb-t2_map.pdf

Please note that it is the responsibility of the end user to ensure that they have the necessary licenses to receive television broadcasts in their country.
