A bit more about HD

The three things which make HD differnet to SDTV are:

  • Frame size This is the number of horizontal pixels x number of vertical pixels, for example 1280 x 720 or 1920 x 1080.
  • Scanning system is progressive scanning rather than interlaced.
  • Frame rate which is identified as the number of video frames per second.
