The abbreviation itself is so dry we cryptically: DVB-T 2. Behind it is concealed the public television broadly advertised antenna television. Despite the high standing of the program providers, DVB-T enjoys little popularity among the population – satellite and cable reception are far ahead.
What advantages does DVB-T 2 have?
This could change with the version of 2. It provides important technical advantages. Up to now, the ARD and ZDF wanted to introduce them only at the end of 2020, but now the start "already" middle 2019 to take place. Still quite late, considering that European neighbors already use the technology.
What is the catch?
The technology has mainly two important innovations in petto. It increases bandwidth efficiency and makes the signals more robust. This gives you the following advantages:
New recipients: eyes on when buying
The mentioned advantages, however, do not all come unrestrictedly to the train. Because the more you want from one, the less you get from the other.
It is up to you to decide which optimizations the transmitters want to make. They have not yet guessed what priorities they want to set.
As with the change from standard pictures to HDTV you also need for DVB-T 2 new receivers. They exist separately as a box or they are already plugged into the TV sets. Many manufacturers already offer suitable equipment for DVB-T 2, but not all.
DVB-C2 and DVB-T2: the future of digital television
Since boxing already from the price category around 50 euros are to be had, this is not so much in weight. If you buy a TV with integrated receivers, however, it looks different. As a rule, the tuners can not be retrofitted.
As an unusual one, one does not have to consider the change of receivers in the TV world any more. Differently than before, there are now continuous further developments, which also increase the TV picture quality. So you can welcome the changes rather than be surprised.
This is also true of UHD technology. It provides the fourfold image point number of the current full-HD resolution and makes the TV images more natural and sharper. But here, too, you will have to change the receiver for satellite and cable reception. In the case of DVB-T 2, UHD should not be an issue for economic reasons well beyond 2019.
More transmitters than before can be transmitted thanks to the higher bandwidth. This eliminates one of the most blatant disadvantages of DVB-T. Above all, the private parties complain that the cost of the transmission is high, but the transmissible transmission offer is very small. Higher picture quality is also available in addition to the larger number of channels. Because of the currently low bandwidth HDTV is not an issue. With DVB-T 2 this becomes different. The standard will no longer serve only as an emergency solution or as a second television, but will also be of interest in home theater systems with larger screens. Improved reception is made possible by the greater robustness of the signals. The present "everywhere TV" is not available at any place. Difficult reception conditions cause image failures or require corresponding antenna installations. However, signals from the second technology are designed in such a way that they are less susceptible to interference and reach a higher range. Mobile TV reception is to be possible thanks to DVB-T as with the radio via the simple, extendable antenna on the device. With good reception conditions and little movement this is actually possible. However, the connection is often quite susceptible. Especially when you are really mobile, on foot or by car, on the road. Here, too, this can improve the performance thanks to improved transmission technology, 2-DVB-T.
View Profile Higher image quality: this conflict is also known from satellite and cable reception. The higher data rate for HDTV reduces the "space" for other stations. Here the program providers have to make a bid decision. Additional HD and SD stations: this competition is only noticeable when receiving the antenna. The robustness of the signals is achieved by means of additional information which can be used by the DVB-T receiver to "repair" damage during the transmission to the picture and sound information. This also consumes space, but increases the reception capability for both stationary and mobile use.
