DVB-S2 stands for Digital Video Broadcasting via Satellite 2.

This is Digital Video Broadcasting for Satellite-TV Version 2.


DVB-S2 has quite a lot of features:

  • It has variable slopes. (Nyquist Rolloff rates)

This eventually affects lot of stuff, since a larger falloff, helps in wastage of transmitted RF power, thus saving energy, quite useful in portable equipment.

  • DVB-S suffers from climatic changes

DVB-S2 supports additionally quite a lot of things to make things better

  • Physical layer Scrambling (helps to improve data integrity)
  • Multiple streams
  • Many more advanced features that it supports more than a MPEG2 TS
  • some of the features allow it work in bad climatic conditions as well
  • Saves bandwdth, not just because of H.264, but because of the sharper filter slope, below a certain value the bandwidth is useless, it just occupies bandwidth that which is not useful
