Problems with HDTV and Analogue

I'm new and got caught in the cross post from the soap opera group but
am glad I found this list..

I have a square screen HDTV capable 36" Sony Wega XBR, about six or
seven years old. I am in Toronto and have hooked up the Rogers HD box
four times only to return it within a day.

Here's why:

The HD reception has many more lines than DVD obviously. It must steal
compression from analogue as when I opt to receive a few things in
analogue the great picture I got with conventional cable is
compromised.


I hate the postage stamp digital channels with top and side margins.

I am electrically sensitive and sense strong emissions from HD. Maybe
the box is not well shielded.

I am really disappointed and don't know what will happen when Rogers
goes all HD some day, likely in 2009.

And these emissions to which you are sensitive are stronger when your
receiver is displaying HD content then when it is displaying SD content?

Yes, much stronger and stronger when playing DVD movies through a
Sony player. Their boxes are poorly shielded metal which must be a
conductor .
audio, I can use a Kloss '88 radio but when I hook up a Sony CD
player to it, it makes me sick at once. Same thing happens if I play
an audio CD in my Sony DVD player. I am really not here to carry on
about the electrical sensitivity as I belong to another support list
for that.

I did a lot of research on compression and how the analogue picture is
subtly advanced when using the HD box and most people are not aware of
it.

Now I'm really curious. Do you have to be looking at the HD produced
image, or is it enough for it to be displayed. Does the sensitivity
diminish when the when the HD stream switches to SD for a commercial?
Could it be that it's just the differing scan rates that trigger your
sensitivity? Are the symptoms different when viewing CRT, LCD, DLP, or
plasma displays? Does projection or direct view make a difference?

I've done a lot of work with DTV image compression algorithms and I have
no idea what you mean by the analog picture being subtly advanced,
advanced relative to what?

I am fascinated about your affliction and electrical sensitivity. Please
can you explain how it manifests itself. Do you get,say, audio reception
through your tooth fillings, or does your whole body start to vibrate at,
say, 60 Hertz? Could you please let us know which group you are discussing
this problem in. I am very curious.

I just had to fend off a marketeer selling some kind of technology to
ward off EMFs and am pretty provoked at the moment. I'll detail my
history briefly tomorrow. I understand my mother was similarly
afflicted but I did not have these sensitivities until I developed an
immune system problem seven years ago.

There is only one solution to your problem... Sit down, loosen your
tinfoil hat and dial: (212) 562-4141; quickly before it's too late!!!

Transmitting HDTV information takes up five times more transmissions
and the quality of analogue is compressed and digitized and pixels
detained and information lost leaving a lousy picture on basic cable.
To transmit in higher compression gives a poorer picture, In analogue,
every pixel is included!
A lot of information gets thrown away but there's still enough to look
like everything is there.
But if other services have to be accommodated it has to be at the
expense of Analog video services
A standard TV screen includes over 300000 pixels per frame To transmit
an HDTV picture, the pixels increase more than five times which means
more BW requirement.
The compression scheme called MPEG-2. is already an industry standard
The compressed video is delivered to the home over the cable network
over QAM.
Analogue 108 Mbps
Analog live Video - Compressed format - 6.0 Mbps
MPEG-2 has some problems, One problem with MPEG-2 is that it's a
"lossy"compression method. That means that a higher compression rate
And using these compression schemes, MPEG-2 can reduce the amount of
bits by about 55. It ruined the excellent reception I used to get on
my analogue basic cable channels 1-42 and no technician would explain
or admit to this flaw in technology.

Sorry, I saved the above but not the source.

Nothing as exotic as fillings receiving. I get absominal swelling,
dizziness, an odd nasal sensation and fatigue.

Lear more by Googling electrical sensitivities.
