Question

What is the diffrence between HD tv and regular tv?

Answer 1

its high definition...better quality

Answer 2

Regular TV was designed in the 1940's to fill a 9-inch black and white screen and mono sound. Color and stereo sound were added a few years later.

HDTV is different because:

- The resolution and color depth is much higher giving a 10 fold increase in picture quality.

- It's digital instead of analog (taking advantage of years of computer technology and monitor development)

- The sound standard is Dolby Digital 5.1 for real surround sound.

Answer 3

HD TV is generally only "HD ready", since there is no HD source included.

Conventional (SD) TV generally operates at 576i (PAL) or 480i (NTSC), for the 625 line or 525 line formats.

HD is 720p or above (720 line progressive).

Possible sources which are above standard definition are:

1. DVD with progressive scan (actually only 576p, but better than ordinary SD, as it can apply inverse telecine to reconstruct 576 line frames at film speed).

2. Upscaling DVD player using HDMI connection (again, not true HD).

3. Blue-ray

4. Satellite or cable box with HD service

NB. HD-DVD (obsolete) will be HD on HD-DVD material, upscaling on normal DVD, at the right price (low!), a HD-DVD player can be quite a good upscaling DVD player.
