The Raspberry Pi 3 Model B+ delivered this year by the Raspberry Pi Foundation is a low-cost, single-card nanocomputer (NanoPC) that is suitable for multiple uses. It is scalable and many hardware components (extension cards) can be added to it to increase its functionality.
Two months ago, the Raspberry Pi Foundation launched a HAT (Hardware Attached on Top), the Raspberry Pi PoE HAT, which enables Pi to be powered via Ethernet using a technology commonly called PoE (Power over Ethernet). More recently, it announced the arrival of HAT TV, a component that once attached to the Pi allows you to watch television on a Raspberry Pi or, even better, to create a TV server to broadcast the stream to other devices connected via a network.
The Raspberry Pi TV HAT (or simply TV HAT) plugs into the Pi’s 40-pin GPIO connector. It has a port to connect a TV antenna. It has been designed so that, once installed, it does not obstruct the display connector.
HAT TV allows you to receive and decode digital television (DVB-T) streams on a Raspberry Pi via its integrated DVB-T2 tuner and then view these streams directly (also called multiplex) or remotely via another device (PC for example) connected to the same network as the Raspberry Pi. The Sony CXD2880 TV tuner it integrates allows it to decode one multiplex at a time, each of them can contain several channels.
It should be noted, however, that it is the end-user’s responsibility to ensure that he or she has the necessary authorizations and licences to receive television broadcasts in his or her country. The TV HAT can be used with a Raspberry Pi 2, 3, 3, 3+ or higher. It supports DVB-T2 TV standards (1.7 MHz, 5 MHz, 6 MHz, 6 MHz, 7 MHz, 8 MHz) and DVB-T (5 MHz, 6 MHz, 7 MHz, 8 MHz) and the following reception frequencies: VHF III, UHF IV and UHF V. It sells for around 23 euros.
“Initially, we will only offer HAT TV in Europe, but compliance work is already underway to open up other DVB-T2 regions,” explained the Raspberry Pi Foundation.
