What does HD-TV 'ready' mean?

[James Buddha]

I'm looking at buying a new tv and don't know what the difference between a
tv that is "hdtv ready" and "hdtv capable"??

'hdtv ready' is a marketing ploy. It means you can connect an HD signal into
it, but does not mean it necessarily has the actual screen resolution to
display it in that resolution. An example of this is some 480p plasma
screens. Their maximum display resolution is 480p, even though they can
accept a 1080i input. These screens downconvert the HD signal to their best
resolution. Bear in mind SD is 576i, and progressive-capable CRTs can
display 576p and will give a better image than those.

Basically you need to ask what the native resolution of the screen is. For
real HD it should be at least 768p. Less than that is not HD, no matter what
the sales drones tell you.

CRT's (Cathode Ray Tubes) use PAL(D) (Phase alternate line (Delayed) on 625
lines, although all the lines are not used, hence teletext which uses the
spare lines. The US use the NTSC (Never the same colour) system on 576
lines. There is one other system for colour television invented by the
French. SECAM. Used throughout the Arab world. PAL, invented by the
Germans is considered the best. PAL(D) is a modification on the original
system.

All Analogue SD Australian transmissions use 625 line PAL D
(interlaced) so all receivers use the PAL D standard. The actual number
of "Active" lines, that is the lines carrying picture information is
585.

In the various versions of 625 PAL "B", "D", "G", "N" etc the letters
all refer to the transmission method, channel spacing and sound
subcarrier frequencies but all use the same video standards so a
monitor will work on all versions. A receiver may not receive sound if
designed for a different version of PAL. This is the problem with PAL
receivers from the UK in Australlia.

There is also a 525 line version of PAL , PAL M which is used in
Brazil.

The USA uses 525 lines for Analogue with NTSC-M.

Digital transmissions use a multitude of standards from 576i, 576P,
720i, 720 P, 1080 i and theoretically 1080P.

There are several versions of SECAM all using the same line scanning
standards as PAL D.

The bottom line is if you have a component signal the originating
standard dosn't matter when it's YUV or RGB they are all the same just
so long as your monitor will work with 525, 625 and if you require HD
standards 576,720 and 1080.

Thanks.. I have a hd/sd stb already, just wondered if i can view HD if I buy
a LCD that is 'HDTV Ready'

[100246.2055@compuserve.com]

You can if it has 1080 and 576 capability.

For instance the 17 inch Philips LCD at a sub $1000 pricetag accepts
HD at 1080 in component and looks excellent.

How good most will look depends on the display resolution as almost all
will "downconvert" for display to whatever the native resolution is.

If you have a 800 X 600 plasma or LCD display obviously you will not
get the full 1920 horizontal pixels displayed on it, you get 800
although you do see
all of the picture at the lower resolution.

99% correct. The 1% refers to NTSC. It actually means Never Twice Same
Colour. LOL :>)
