Presentation Transcript
slide2
Communication Theory, Analog or Digital
  • Any systems approach to electronic imaging dictates that TV signals and TV sets speak the same language….
slide3
MSNBC Headlines...
  • History of TV from John Logic Baird’s 28 line spinning disc in 1923, the 1935 343 line RCA system, the 1936 RMA 441i/30 to the 1941 NTSC 525 line we watch now & HDTV
slide4
How Many Lines Do We need!
  • ISO 12233 Standard for “Type A Aliasing”

slide8
Why Calibrate?
  • Leaving your HDTV at the factory picture settings is like installing a new air conditioner without setting the thermostat. Basic picture adjustments take less than five minutes and could improve your TV\'s performance dramatically.
  • Brent Butterworth, Editor-in-Chief, Home Entertainment Magazine
slide9
Why Calibrate II?
  • “Calibrating your television will likely have a far greater impact on the picture’s quality than the brand, features or technology used to create it”
  • Mike Wood, Editor in Chief, Digital TV & Sound
slide10
Why Calibrate III?
  • "Every Runco HDTV is engineered for ISF calibration. Understanding TV calibration is simple at our company - calibrating Runco HDTVs insures happy Runco HDTV owners. Period".
  • Sam Runco, Runco International
slide11
Why Calibrate IV?
  • "We manufacturer Faroudja HD processors, HDTV displays and Meridian DVD players. We consider ISF calibration to be an essential last step in optimizing your system to achieve the same performance as we do in the lab. Over the years myself and all of my sales guys have attended ISF training and always carry calibration DVDs whenever we visit our dealers."
  • Norm Steinke, VP sales Faroudja/Meridian
slide12
Why Calibrate V?
  • "Pioneer Plasma HDTVs are specifically engineered for precise on site ISF calibration - Pioneer was the 1st manufacturer with ISFccc certification - calibration will make even the best HDTVs look even better by adjusting your HDTV to the exact lighting in your own home." 
  • Josh Kairoff, Pioneer Electronics USA
