You ask, we answer.

Currently, millions of Poles watching TV use built-in TV sets or external DVB-T decoders. These devices allow free reception of digital terrestrial television. These decoders will soon prove to be useless – all through change of broadcasting standard. Therefore, Internet users ask a lot of questions on the Internet, which I decided to answer here.

1. When will the broadcast signal change in Poland?

The change will enter into force before June 30, 2022. A statement by the National Broadcasting Council suggests that it will be as close to this date as possible. Interestingly, countries neighboring Poland, including the Czech Republic, Germany and Austria are already using the new generation of signal.

2. What decoder do I need to receive digital terrestrial television after changes?

DVB-T decoders with MPEG-4 will be replaced by newer DVB-T2 decoders with HEVC. It is the new generation decoder that will be necessary to be able to continue to receive the signal for free, under RTV subscription.

3. Does the TV need to have a built-in DVB-T2 decoder?

The answer to this question is simple: no. If your current TV does not support the newer standard, there is no reason to panic. Instead of buying a new TV, all you need is a much cheaper decoder that supports the modern standard.

4. Does my TV have a built-in DVB-T2 decoder?

There is a high probability that … yes! According to estimates forecasted by the Digital Poland Association, in 2019 in Poland even about 62% of TVs in households had a decoder adapted to receive a new signal. If you are not sure if your model supports it, enter your device's model name in Google and attach the phrase "DVB-T2" or contact the manufacturer's technical support.

According to the same report, in the last five years as many as 7 out of 11.5 million TVs sold in our country enable the reception of DVB-T2 digital terrestrial television. It is estimated that by 2022 as many as 91% of households will have television sets supporting DVB-T2.

5. What is the difference between DVB-T and DVB-T2?

The newer DVB-T2 standard primarily uses more modern HEVC encoding (H.265 / MPEG-H part 2), which ensures identical image quality with twice as little bandwidth consumption. In theory, the sender will be able to emit a signal in even higher resolution and in better sound quality. DVB-T2 also has a larger multiplex capacity (40 Mb / s in 8 MHz vs 24.88 Mb / s in 8 MHz), thanks to which it is possible to broadcast a larger number of channels. Due to the freeing of the 700 MHz band for the needs of the 5G network, the signal will be transmitted on frequencies in the 470-694 MHz range.
