That ol' HD confusion thing..

Killing time in Morrison's while the wife was doing the shopping, I
wandered over to the 'electrical section', as we have been talking about
getting a small TV for the guest bedroom, and I thought that I might
see what was on offer.
The two smallest sets they had (of three), with their brand name on
them, were a 22" Full HD set, with 1080p resolution, and a 24" set, HD-Ready, with 720p resolution.
I thought that HD-Ready was supposed to include at least 1080i
resolution ability.
I think I'll go to a proper shop anyway.

Morrisons have no idea on technology of TV sets. Stick to buying cans of
beans there.

Excuse me, are these beans really broad, or just anamorphic?

Have no fear. They have been known to carry Verbatim DVDs, though.

Not necessarily. Internationally, 720 is classified as HD, along with
1080i/p.

As the table here shows, HD Ready means "720 horizontal lines (rows) in
widescreen ratio" and HD Ready 1080p means "1920×1080":
http://en.wikipedia.org/wiki/HD_read...ents_and_logos

http://en.wikipedia.org/wiki/Full_HD

The AV equipment manufacturing industry has adopted the term Full HD
as the consumer-friendly marketing term to mean the set is a safe
purchase because it can display all available HD resolutions up to
1080p. The term is misleading, however, because it does not
guarantee the set is capable of rendering digital video at all frame
rates encoded in source files with 1080 pixel vertical resolution.
Most notably, a "Full HD" set is not guaranteed to support the
1080p24 format, leading to consumer confusion.

We've discussed this before. The problem is that the sellers are trying
to use short phrases when longer descriptions would be more accurate and
complete.

Actually, I wouldn't. In my experience the staff are just as clueless.

What I do is research the product(s) extensively on the web, so I'm
sure I understand exactly what I'm getting (and what I'm not).

They I buy it from John Lewis, because they often give good guarantees
and in any case I want to support them.

A set that is marked 'HD ready' will only do 1366x768
resolution or around 1Mp. It will usually accept 1080i but
you won't see much difference - certainly not on small
screens like those.

Full HD is designed to work with 1920x1080 or around 2Mp so
you get 70% better resolution and the picture will
subjectively seem sharper even in SD.

In terms of broadcast, most transmission upscales to 1080i
especially if it is moving only going to 1080p when static.
Having said that the only way a broadcast signal will do
1080anything is by upscaling as both DTTV and Sat both use
720p native.

AIUI native 1080p can only be obtained from a Blu-Ray disc.

What annoys me sets labelled HD do not in many cases have Freeview HD TV
stations.
Morrisons in particular with their TV sets and digi boxes are only SD, the
staff think they have the very latest standards.

Depends what you mean by 'Native 1080p' ?

1080p25 is alive and well and in use on Freeview HD transmissions
on the PSB 3 mux, on a GOP by GOP basis the encoders look at the
picture content, and if there's no difference between field 1
and field 2 of the 1080i50 signal, then the encoding switches
to 1080p25 mode. Been like that for a couple of years now.

Not sure about Mux 7 ? the Beeb don't encode that, like D-Sat
that's fixed at 1080i50 I think, regardless of content.

BluRay supports 1080p24, (for movies in their native frame rate)
or 1080i50, I don't think it can support 1080-p at anything beyond 24p.
It can only do 50p at 720 resolutions ?

Yes indeed. Much the same seems to go for Tesco. A friend told me that they
don't know what an hdmi lead is.
Well the droid on duty didnt.
