Progressive/Interlace
The PAL video signal standard has 576 (or 625) interlaced (i) scan
lines, whereas progressive scanning, called 576p (or 625p), uses
twice the number of scan lines. For the NTSC standard, these are
called 480i (or 525i) and 480p (or 525p) respectively.
Using progressive output, you can enjoy the high-resolution video
recorded on media such as DVD-Video.
Your television must be compatible to enjoy progressive video.
Panasonic televisions with 576 (625)/50i · 50p, 480 (525)/60i · 60p
input terminals are progressive compatible.
Protection
You can prevent accidental erasure by setting writing protection or
erasure protection.
RGB
This refers to the three primary colours of light, red (R), green
(G), and blue (B) and also the method of producing video that
uses them. By dividing the video signal into the three colours for
transmission, noise is reduced for even higher quality images.
Sampling frequency
Sampling is the process of converting the heights of sound wave
(analog signal) samples taken at set periods into digits (digital
encoding). Sampling frequency is the number of samples taken per
second, so larger numbers mean more faithful reproduction of the
original sound.
Thumbnail
This refers to a miniature representation of a picture used to
display multiple pictures in the form of a matrix.
1080i
In one high-de
fi
nition image, 1080 (1125) alternating scan lines
pass every 1/50
th
of a second to create an interlace image.
Because 1080i (1125i) more than doubles current television
broadcasts of 480i (525i), the detail is much clearer and creates a
more realistic and rich image.
1080p
In one high-de
fi
nition image, 1080 (1125) scan lines pass at the
same time every 1/50
th
of a second to create a progressive image.
Since progressive video does not alternate scan lines like interlace,
there is a minimal amount of screen
fl
icker.
720p
In one high-de
fi
nition image, 720 (750) scan lines pass at the same
time every 1/50
th
of a second to create a progressive image. Since
progressive video does not alternate scan lines like interlace, there
is a minimal amount of screen
fl
icker.
