Types of DVB S2 Linux

DVB-S2 is an international standard for digital satellite television broadcasts received via satellite dishes and set-top boxes. It is based on the DVB-S standard and utilizes a more advanced transmission scheme that offers higher efficiency and better error correction capabilities. This makes it possible to broadcast multiple channels simultaneously on a single frequency using different bandwidths.

Linux is an open-source operating system widely used in various computing devices, including satellite reception equipment. A DVB Linux device for satellites typically consists of a satellite tuner (or tuner card) connected to a computer running the Linux OS. It can receive satellite signals from a dish antenna and decode them using software running on the Linux system, allowing one to watch and record satellite TV channels directly on their computer.

The following are some types of Linux devices that can be used to receive satellite signals:

• PC Tuner Cards: In earlier times, people would use PCs with tuner cards installed as satellite receivers. These tuner cards would connect directly to the satellite dish and were capable of tuning into different frequencies to get the signal from satellites. With advancements in technology, dedicated boxes have replaced using a PC with a tuner card installed as a satellite receiver.
• Tuner USB Devices: Some small USB devices called tuner USBs are made for receiving satellite signals. They can be plugged into the USB port of a computer running on Linux. Similar to tuner cards, these tuner USBs work like a satellite tuner built inside them. Their purpose is to receive satellite signals so that one can watch and record TV channels on their computer just like using a tuner card before.
• Network Attached Tuners: Some satellite receivers are specifically designed to work with televisions and computers via networks. These dedicated box-type satellite tuners connect directly to a dish placed outside and receive the satellite signals into it. From there, they could then share the received signals over a network in the home, such that computers or televisions located anywhere within the home network could access them. This is done through an Ethernet cable connecting the tuner to a router or switch in the network.
• Integrated Receivers: Some satellite tuners are built directly into devices like digital recorders or multimedia centers. These combined units contain both the satellite tuner function, which allows them to get satellite signals, and also serve additional purposes like recording TV programs or playing multimedia content. Having the satellite tuner integrated within these types of devices eliminates the need for separate external tuners, as they already serve that purpose in addition to other functionalities.

Function and features of DVB S2 Linux

The satellite TV system can deliver excellent video quality with more programs using the current satellite systems. Viewers can have exciting TV watching and listening experiences with more channels.

• Advanced Features

  The Linux-based DVB S2 receiver has advanced TV features, such as electronic program guides, interactive services, and multimedia broadcasts. These advanced features boost the viewing experience and make TV watching more enjoyable.

• Cost Saving

  The DVB S2 Linux system can be a cost-effective satellite TV solution. Its better reception reduces the need for technical support, thus saving costs. The system can deliver excellent video quality with fewer expenditures and offers good value to viewers.

• Customization and Flexibility

  Using the DVB S2 Linux receiver gives room for customization and flexibility. System designers can add new features and functions to the receiver to meet specific needs. They can improve the viewing experience with tailored services. The flexibility in customization allows set-top box designers to deliver desired viewing experiences.

• Digital Broadcasting

  The S2 part of the DVB is for digital satellite and adds features for new technology. It is made for digital signals, which are better than the old analog signals. The DVB S2 uses the BETACAM digital recording system. The system can help broadcast digital video to many viewers using satellites instead of cables or the internet.

• Multistream Reception

  DVB S2 allows the reception of multiple satellite signals at the same time. Broadcasters can send different language audio tracks and alternate game feeds for major sports events. It creates a better experience for viewers.

• FEC (Forward Error Correction)

  The error correction part of the system improves the reliability of a shaky satellite signal. The system can help reduce transmission errors, so video quality stays good. The transmission error correction keeps video quality high, even when satellite signals are poor.

Scenarios

• Satellite TV Reception:

  One of the primary uses of DVB-S2 is to receive satellite television. In many countries, especially those with remote or rural areas, satellite TV is a crucial service. Using a satellite dish and receiver, one can watch hundreds of channels from different satellites. DVB-S2 is the upgraded version of DVB-S, offering better picture quality like 4K UHD and advanced features like interactive TV and more channels.

• Digital Satellite Radio:

  DVB-S2 is not just for TV. One can use it to get digital satellite radio services for an excellent high-quality listening experience. Many satellite radio programs in different languages are available across various genres. These, too, are received using a satellite dish and decoder.

• Regional and International Broadcasting:

  DVB-S2 allows the reception of satellite television broadcasts from both local satellites and those belonging to other countries. This is important for receiving international channels in diverse communities and for specific regions where local programming is inadequate.

• Cable Television Transmission:

  Besides satellites, cable TV providers also use DVB-S2 for delivering television signals to homes via cables. Cable subscribers can utilize their set-top boxes or receivers to watch various channels and programs encoded with DVB-S2.

• Broadcasting Content to Multiple Locations:

  Similar to how cable companies use DVB-S2 to send content to customers, some businesses use it for sharing content among offices or within a business. For example, a company with multiple branches can use DVB-S2 to transmit training materials or videos to all its locations from a central site.

• Hospital and Hotel Entertainment Systems:

  Hospitals and hotels often have entertainment systems so that patients and guests can watch TV. Many of these facilities use DVB-S2 to provide various television channels. Usually, a DVB-S2 receiver is connected to a multi-room system that distributes TV signals to different rooms or lounges where patients or guests can watch TV.

• Applications for Surveillance:

  In some cases, those working in security or monitoring use satellite systems like DVB-S2 for viewing CCTV cameras over long distances. Security personnel can decode and view multiple camera feeds on a monitor.

• Data Streaming:

  People in remote areas lacking reliable internet can use DVB-S2 for receiving updates like weather reports and other data through a TV. A service known as broadcast data application (BDA) allows users to get text, graphs, and images that help them stay informed. Fishermen, researchers, and field workers find this service handy. While DVB-S2 is mainly for video and audio, it has other uses like receiving messages.
