Techopedia Explains Digital Video Broadcasting-Satellite Second Generation

DVB-S2 is based on DVB-S and electronic news gathering specifications. This system is specially designed for the following:

  • High-definition and standard definition TV (HDTV and SDTV) broadcasting
  • Interactive services, such as Internet access
  • Professional applications, including news gathering and digital TV contribution
  • Internet trunking and data content distribution

The DVB-S is used by mobile units for sending sounds and graphics from anywhere in the world back to home television stations. The development of DVB-S2 corresponds with the introduction of HDTV and H.264 advanced video codes. The evolving process from DVB-S to DVB-S2 is anticipated to be complete by approximately 2020. The reason behind this long upgrading process is that the DVB-S is recognized as a flexible and well-designed standard among multimedia engineers and professionals, which works well and does not need to be revised immediately.
