What is the difference between them

Each TV is capable of working with the standards specified by the manufacturer. This means that from a technical point of view, by connecting a cable from the appropriate source to the appropriate connector, a television receiver can provide high-quality source reception. In practice, obtaining video is complicated by the fact that the quality of the incoming signal may not be high enough. This will prevent you from getting good picture and sound. For example, this situation arises if the satellite tuning is done poorly. Another problem has to do with channel encryption. In some cases, in order to be able to view certain programs, you need to pay for them to the provider. It will issue either a receiver capable of receiving them or a CAM card that will automatically decode the video and make it available for viewing.The use of DVB S2 provides users with the following advantages:

  1. DVB S is the most common standard for watching satellite TV. The high quality of the display brings the more serious to the nodes that provide reception. DVB S2 provides better reception quality.
  2. Some channels broadcast only in DVB S2. Having the ability to view only DVB S, you cannot access them. Thus, if the user wants to have access to modern broadcast channels with high quality, he will need to focus on using the new option.
  3. Information transfer rate is 30% higher.
  4. Using DVB S2, the user gets access to more HD channels.

The use of the new standard is more economical in terms of energy costs.

What DVB S2 is capable of

The DVB S2 tuner has a higher quality of work. It is able to provide the owner with the following benefits:

  1. It can easily support standard television viewing along with regular television.
  2. The standard in question is, in contrast to DVB S, two-way. It not only allows receiving information from the satellite, but also transmitting it in the opposite direction. This allows you to use it to get satellite Internet access.
  3. This tuner allows other devices to connect to the Internet.
  4. Reduces the level of distortion when receiving a satellite signal.
  5. The risk of freezing while watching an image or sound is eliminated.

Communication using this option is faster and more reliable. If there is a built-in tuner, this makes it possible to watch unencrypted channels. Typically, these are no more than 10 percent of their number. To view the rest, you will need to purchase a CAM card from the provider. If the setup is done correctly, it becomes possible to view open channels from several providers. This allows access to a significant number of transmissions. By purchasing a TV with a built-in tuner, the user saves on the purchase of a receiver. In addition, this reduces the use of unnecessary wires in the apartment. The disadvantage of DVB S2 is still its low prevalence. At the same time, the number of such channels is constantly growing, making the connection more and more profitable.
