what is upscaling

[jayantadak]

Hi,

Reading a lot regarding upscaling. For sure, I don't exactly know what's that. Is it related to audio or video. How far does it affect the audio/video experience when one watches the Dolby digital stuff which is around. Does upscaling comes into picture when we watch HD /Blue ray movies. Pl. enlighten me.

Upscaling = "search on the forum and read the many posts related to it"

Sorry am being hard but you should first be searching before posting out the question that came to your mind.

Hi Jayant

Definition: Upscaling is a process that mathematically matches the pixel count of the output of a standard or non-hi-def signal (such as standard DVD) to the physical pixel count on an HDTV, which is typically 1280x720 (720p) or 1920x1080 (1080i or 1080p).
720p represents 1,280 pixels displayed across the screen horizontally and 720 pixels down the screen vertically. This arrangement yields 720 horizontal lines on the screen, which are, in turn, displayed progressively, or each line displayed following another.

1080i represents 1,920 pixels displayed across a screen horizontally and 1,080 pixels down a screen vertically. This arrangement yields 1,080 horizontal lines, which are, in turn, displayed in two successive fields of 540 lines (interlaced scan).

1080p represents 1,920 pixels displayed across a screen horizontally and 1,080 pixels down a screen vertically. This arrangement yields 1,080 horizontal lines, which are, in turn, displayed progressively.
