Type of TV (interlaced or
■
progressive scan)
Many TVs use interlaced video.
Interlaced video displays a video
frame with two passes of
alternating scan lines. The TV screen
first displays the video image odd
lines one at a time, sequentially
from top to bottom, then it fills in
the other half of the video image
with the even lines. Because most
TVs use this interlaced method to
display the picture on the screen, a
standard interlaced analog TV will
most likely flicker when displaying
thin lines and small text. An
interlaced video display device will
produce a lower quality display,
especially when viewing and using
the Media Center computer
functions.
Progressive scan video displays a
video frame with one pass of
sequential scan lines. A progressive
scan TV displays the entire picture,
drawn sequentially from top to
bottom, without the odd/even
interlacing. This results in a fuller,
sharper picture and better display
quality for viewing and using the
Media Center computer functions.
The progressive scan picture is also
brighter and easier on your eyes.
