Aspect Ratio | The ratio between the width and height of the TV picture on the screen. In a normal TV set the aspect |
| ratio is 4 to 3 (4:3). The new aspect ratio in HDTV is 16:9 which resembles the aspect ratio in a movie |
| theatre (Widescreen). New TV systems support both 4:3 and 16:9 aspect ratio and can automatically |
| switch between them. |

Audio Video (A/V) | A term often used when discussing a channel on a TV receiver or on video equipment, which has been |

|
HDTV | The generally agreed upon definition of HDTV is approximately twice the vertical and |
| horizontal picture resolution of today’s NTSC TV, which essentially makes the picture twice as sharp. |
| HDTV also has a screen ratio of 16:9 as compared with most of today’s TV screens, which have a screen |
| ratio of 4:3. HDTV offers reduced motion artifacts (i.e. ghosting, dot crawl). |
|
|
Progressive Scan | In Progressive Scanning all the horizontal scan lines are scanned on to the screen at one time. The HDTV |
| Standards accept both Interlaced Scan and Progressive Scan broadcast and display methods. |

Resolution | Resolution: A measurement of the finest (smallest) detail that is visible in a video image. TV Resolutions |
| may be expressed as number of pixels in an image; or more commonly, |
| As Total Number of (horizontally scanned) Lines used to create the image. |
| Standard Digital TV Resolutions: |
| SDTV: 576i - The picture is 720x576 pixels, 576p - The picture is 720x576 pixels. |
| HDTV: 720p - The picture is 1280x720 pixels, 1080i - The picture is 1920x1080 pixels, |
| 1080p - The picture is 1920x1080 pixels. |
| Note: 32PFL7422 doesn’t support to 1080p |
