  15. VIDEOSCREENS • When seated too close, the scanning lines on the tube or the pixels on the projectors will be apparent. • Seating far enough back will blend these details to the human eye.

  16. VIDEOSCREENS • Movie theaters are designed so that viewing angles are reduced to provide more realistic images. Prime seating is designed to view the movie at a 30 degree angle (peripheral view of the human being). • When adopting this design to the home theater; visual scanning lines and pixels are detected.

  17. VIDEOSCREENS

  18. SEATING RANGE DILEMMA • Seating distance to overcome visual image structure is typically 4X the height of the video screen. • Or this distance can be also measured as 3X the width of the screen. • These two parameters are commonly recommended distances by projection screen manufacturers.

  19. DVD • Innovative creation of digital and audio and video. • Can play up to 133 minutes of full motion video on a single sided disc (92% of all movies ever made).

  20. DVD • Picture quality approaches “D-1” studio production standard. • Over 500 lines horizontal resolution (240 lines VCR). • Up to 8 languages and 32 subtitles.

  21. DVD • Choice of PCM stereo sound or digital multi channel surround. • Supports letterbox, pan and scan or 16 X 9 formats. • Holds 4.7 gigabytes of data per layer (compared to 680 megabytes of data on a CD). • Offers dual layer double sided disc options.

  22. DVDFUTUREAPLLICATIONS • The ability to view scenes shot at multiple angles. • Recordable, rewritable and high definition media.

  23. PROGRESSIVE SCAN DVD • PLAYERS WITH PROGRESSIVE SCAN WILL OFFER OUTPUTS FOR HDTV READY DISPLAY MONITORS. THE PLAYER WILL THEN BE CAPABLE OF RECONSTRUCTING 3/2 PULLDOWN EFFECT INTRODUCED WHEN THE FILM-BASED PROGRAMS ARE TRANSFERRED TO VIDEO. RESULTS IN THE BEST PICTURE QUALITY AVAILABLE!
