Whats the difference between regular TV channels and HD channels?
Question:
Answer:
If you receive the HDTV broadcast and you have a HD television, you will receive a much clearer, more defined and less of a pulsating image. The HD picture will also be easier on your eyes because it does not scan to form a picture. If you have a camcorder or digital camera and viewed a standard TV and compared it to a digital/HD TV looking through the LCD screen, you will see the scan line in the standard TV. You don't feel it at first, but your eye will get tired quicker on the standard TV.
In addition to that, a lot of the HD broadcasts are in widescreen or letterbox (black bars) format.
Ummm It a clear sharper image I mean it High Defination man of coure it will look better be sure to use good cables for the best picture
HD is sending more pixels per sq unit than regular tv so you get a more in depth view of the image.
When resolution is considered, both the resolution of the transmitted signal and the (native) displayed resolution of a TV set are taken into account. Digital NTSC- and PAL/SECAM-like signals (480i60 and 576i50 respectively) are transmitted at a horizontal resolution of 720 or 704 "pixels". However these transmitted DTV "pixels" are not square, and have to be stretched for correct viewing. PAL TV sets with an aspect ratio of 4:3 use a fixed pixel grid of 768 × 576 or 720 × 540; with an aspect ratio of 16:9 they use 1440 x 768, 1024 × 576 or 960 × 540; NTSC ones use 640 × 480 and 852 × 480 or, seldom, 720 × 540. High Definition usually refers to one million pixels or more.
In Australia, the 576p50 format is also considered a HDTV format, as it has doubled temporal resolution though the use of progressive scanning. Thus, a number of Australian networks broadcast a 576p signal as their High-definition DVB-T signal, while others use the more conventional 720p and 1080i formats. Technically, however, the 576p format is defined as Enhanced-definition television.
there will be a huge difference! of course.
standard channes broadcasts at 420i.
HD channels broadcasts at 1080i. it just means that the pixels are a lot smaller.
and make sure to use an HDMI cable
