  16. Display Aspect Ratio The Great Train Robbery (1903) How film appears on screen Old film and TV standard is 4 x 3 (1.33 : 1)

  29. But, the Solutions are Imperfect • Pan and scan format: • shows the most important action • uses all the TV screen • 30 to 60 percent of the movie is still lost • Letterbox format: • shows everything in reduced size • uses part of the TV screen • 30 to 60 percent of the screen is wasted

  30. The Director’s Message is Changed

  31. Display Aspect Ratios (DARs) Abound

  35. Digital Versatile / Video Disk (DVD) • Replaces • CD-ROM (also supported by player) • Audio CD (also supported by player) • Laser videodisc • Offers support for 4 x 3 DAR • Maximizes HD with 16 x 9 DAR and high computer PAR

  36. 4.7 GB (clear layer) 8.5 GB (dual layer; = 13 CDs) 9.4 GB (one layer) 17 GB (dual layer; = 26 CDs) 133 min. MPEG-2 5-channel Dolby DSS CD-ROM versus DVD Capabilities 650 / 800 MB Single-sided 19 min. of video Stereo (2-channel)
