A DVB-T stick (also known as a USB TV stick ) is a small receiver for DVB-T television signals that is connected to the PC or laptop via a USB interface. The signal is decoded using the software supplied. Modern DVB-T sticks use diversity technology to ensure good reception quality even in areas with weak transmission power. Two DVB-T receivers are used in one device at the same time, bundling their received signals. This technology also makes it possible to receive two different stations at the same time, for example to record and watch programs in parallel. Some software enables this even without diversity technology if the transmitters are on the same multiplex . Often, DVB-T sticks are supplied with BDA drivers , which means that the user has a large selection of viewing software available from the Internet and does not have to stick to the manufacturer's program supplied.

With regard to the transmission standard for DVB-T, there are currently two systems: DVB-T and DVB-T2 . DVB-T2 receivers are usually backwards compatible with DVB-T. With DVB-T2, MPEG-4 is also used as the standard video compression, in contrast to DVB-T with MPEG-2, but this has nothing to do with the DVB-T stick hardware, so you could also use MPEG- Receive 4 compressed channels. However, VISEO + , the only German example of this, is encrypted. In Germany, DVB-T2 uses HEVC compression, which places significantly higher demands on the CPU.

Current providers of DVB-T sticks are ADS Tech , AVerMedia , Digittrade , dnt , Elgato , Emtec , Genius , Hama , Hauppauge , PCTV Systems , takeMS , Teac and TerraTec . The scope of delivery usually includes a remote control and a small indoor antenna with a magnetic base, which should be placed on a small piece of sheet metal near the window: upright for a vertically polarized transmitter and horizontally for a horizontally polarized transmitter (see article on the transmitter mast for polarization).

With the switch from DVB-T to DVB-T2, TV reception is no longer possible with DVB-T sticks that do not support DVB-T2. There are two applications for sticks with a chip from the Realtek RTL2832 series that can still be used:

  • With the DAB Player software (see web links) you can receive DAB + (digital radio).
  • In the RTLSDR project , the devices are used to receive almost any broadcast, such as VHF radio.
