Australia, and parts of Central and South America. PAL format displays at 625 scan lines (rows) of
resolution at 25 frames per second (25Hz)

Pixel
Pixel is the most basic element of a display. The resolution of a monitor is defined by the number of
pixels existing horizontally and vertically within the screen part of the monitor. 1 pixel consists of 1
or a number of bits in storage media. The more bits a pixel consists of, the more range of brightness
and color can be expressed. For example, a display device offering 24 bits per pixel can express
16.7 million hues.
A pixel consists of one or more dots in a screen. In a colored display, a hue is defined by a mixture
of red, green and blue dots of different strengths.
Pixel Resolution
Pixel resolution is classified by resolution as follows.
- VGA: 640 x 480
- SVGA: 800 x 600
- XGA: 1024 x 768
- SXGA: 1280 x 1024
- SXGA-Wide: 1600 x 1024
- UXGA: 1600 x 1200
- HDTV: 1920 x 1080
- UXGA-Wide: 1920 x 1200
- QXGA: 2056 x 1536
HDTV
HDTV (High Definition Television) offers clearer pictures (higher resolution) than ordinary TV.
It usually is wider than present NTSC and offers twice as higher resolution. In order to transmit high
resolution picture through present TV bandwidth, a picture is digitized, compressed and signalized
before transmission and when it reaches each home, its data is decompressed and separated before
displaying on the monitor.
DxVA
DxVA (Direct X Video Acceleration) is hardware-wise processing of some of the functions
necessary for MPEG decoding and encoding such as Hardware Motion Compensation iDCT DCT
and color space conversion, etc.
