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 list.
1080i
In one high definition image, 1080 (1125) alternating scan lines pass
every 1/50th 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 definition 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 flicker.
720p
In one high definition 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 flicker.
