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

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

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.
