P.SCAN
(Progressive Scan)
Function
Unlike regular Interlace Scan, in which two fields of picture information alternate to create the
entire picture (odd scan lines, then even scan lines), Progressive Scan uses one field of
information (all lines displayed in one pass) to create a clear and detailed picture without visible
scan lines.
While the player is in the Stop mode, hold the P.SCAN button down for longer
than 5 seconds.
•
The selection switches back and forth between " P.SCAN " and " I.SCAN " each time the button is held
down for a minimum of 1 second.
• The previous mode is indicated in the display first, followed by the selected mode in about a second.
In interlaced-scan video, a frame consists of two
interlaced fields (odd and even), where each field
contains every other horizontal line in the frame.
The odd field of alternating lines is displayed first, and
then the even field is displayed to fill in the alternating
gaps left by the odd field to form a single frame.
One frame, displayed every 1/30th of a second, contains
two interfaced fields, thus a total of 60 fields are
displayed every 1/60th of a second.
The interlaced scanning method is intended for capturing
a still object.
Interlaced Scan (1 FRAME = 2 FIELDS)
The progressive scanning method scans one full frame of
video consecutively down the screen, line by line.
An entire image is drawn at one time, as opposed to the
interlaced scanning process by which a video image is
drawn in a series of passes.
The progressive scanning method is desirable for dealing
with moving objects.
Progressive Scan (FULL FRAME)
What is Progressive (or Non-Interlaced) Scanning?
• This function works only on TVs equipped with component video inputs (Y, Pr, Pb) that support Progressive
Video. (It does not work on TVs with conventional component inputs, i.e., non-progressive scan TVs.)
• Depending on the brand and model of your TV, this function may not work.
