What was wrong with the old Analog system?

  • 1930’s Technology
  • Black & White
  • Monophonic Sound
  • Maximum Screen Size: 19 inches
  • Kluged Retrofits: Still not close to photographic and larger-than-life quality of movies.

Digital Television

Why Now? Actually it started in the 1980s

  • Congress Feared Further Technology & Patent Drain

Digital Television

Why Now? Actually it started in the 1980s.

  • Congress asked American companies to develop a more/better American System
    • Offered no government funding but instead enticed with opportunities for patent royalties.
    • Would conduct “fly-off” of all submitted systems.
    • 4 teams of companies entered the competition.

Digital Television

Why Now? Then Why Did It Take So Long To Develop?

  • Broadcasters insisted on being included; i.e. the high definition system would have to fit within current licensed stations (6 MHz Bandwidth/Channel).
    • The Japanese system had required higher bandwidth cable and satellite distribution.

  • FCC conducted not one, but three flyoffs over 10 years and found no system satisfactory.

  • FCC conducted not one, but three flyoffs over 10 years and found no system satisfactory.
  • During the third flyoff, one team proposed a digital system which showed promise.

Digital Television

Why Now? Then Why Did It Take So Long To Develop?

  • The four competing teams of companies and research institutions were about to drop out of the development: over 10 years of IR&D with no return in sight.

  • The four competing teams of companies and research institutions were about to drop out of the development: over 10 years of IR&D with no return in sight.
  • The FCC suggested that the four teams agree to share patent royalties and combine efforts to use the best of all proposed systems.

  • This Grand Alliance completed development of the current “ATSC” system in the mid 1990s and the FCC adopted it in 1997.

Digital Television
  • Wide-Screen Aspect Ratio

* * * *

* * * *

* * * *

* * * *

Resolution 4 Hor. X 4 Vert. = 16 Pixels

Aspect Ratio 4:4 or 1.0 to 1.0

digital television28
Digital Television
  • “Academy” Aspect Ratio

* * * *

* * * *

* * * *

Resolution 4 Hor. X 3 Vert. = 12 Pixels

Aspect Ratio 4:3 or 1.33:1.0

Analogue TV Has Theoretical 640 Hor. X 480 Vert. = Aspect Ratio 1.33:1.0

digital television29
Digital Television
  • Wide Aspect Ratio
    • Typical Movie Aspect Ratios - 1.33:1.0 (Edison),1.66:1.0, 1.85:1.0, 2.05:1.0, 2.35:1.0
    • How can HDTV accommodate all these aspect ratios? Take the geometric mean - 1.78:1.0
    • Actual Pixel Counts
      • 1280 X 720 = ~1 Megapixel; Refreshed 60 Times/Sec.
      • 1920 X 1080 = ~2 Megapixels; Refreshed 30 Times/Sec.

3. 5.1 Dolby Digital Surround

  • Left Front, Center Front, Right Front, Left Surround, Right Surround, Subwoofer
  • Also Carries Regular Stereo For TV Speakers

What Happens To My Old TVs When Analogue TV Is Turned Off on Feb 17, 2009?

  • Will need a converter box
    • Satellite receiver
    • Cable Box
    • Over-The-Air Box
  • Picture will still be standard definition on old TV, and will be letterboxed to accommodate wide-screen programs (or else 1. the sides of the picture will be cut off or 2. everyone will look really thin!)

The Coupon Progam

  • Nielson estimates 14.3 million US households rely on over-the-air TV. That’s 12% of the nation’s households.
  • Each household can apply for up to 2 $40. coupons to spend on ATSC digital tuner boxes for analog TVs.
  • Congress has allotted $1.5 B for the program to be administered via the National Telecommunications and Information Administration. = 33.5 Million Coupons.
  • Boxes are expected to sell for $50. - $70. 250 major retailers have been approved to sell them.
  • More than 1 million households have requested and received coupons so far.
