I heard about the japanese HiVision(or something like that) discs and was
wondering what's known about them? I know they're 1125 lines of res.

Also, I have a japanese import laserdisc on the way to me in the mail
right now. It's Genesis Invisible Touch tour from 1987 and it says on the
cover "SONY HI-DEF" this doesn't have anything to do with HiVision does
it? Does it just mean they mastered it well?

If it is a Hi-Def disc, I doubt if it will play in your standard LD
machine. More than likely, it was mastered from a Hi-Def source into
standard NTSC video.

HiVision, also called "Muse" discs were essentially standard discs containing
compressed High Def material. There was a small selection of movies avaliable
on the format, as well as a small catalog of "special interest" films. The
discs require a MUSE capable player, such as Pioneer's HLD-X0 or HLD-X9 as well
as a special decoder and an HDTV. Obviously, an RF demodulator is neccesary if
you're interested in AC-3 soundtracks, but not otherwise. Here is a list of
MUSE titles:

According to the database, the concert was filmed using 1125 line Sony Hi-Def
cameras, but it's a standard NTSC disc in widescreen. So no, it's no a HiVision
disc, and your current player can handle it. If the transfer was any good, the
video quality should be great. Here's the disc:

I've never seen a HiVision LD with a separate AC-3 soundtrack. HiVision has
its own multi-channel Audio encoding that is decoded in the MUSE decoder.
Since I cannot read Japanese I cannot give the details from my owners manual
for my decoder.

Hello,

Hi-Vision LDs (through a decoder) can be watched on a 1080i compatible
display.

Rgds,
Julien

You have a HiVision player? I didn't think that would be able to work on an
american HDTV. The only modes they support are 480i/p, 720p and 1080i.

1. Sound

Hi-Vision pre-dates Dolby Digital. At best it has discreet Dolby
Surround (ie, 4 separate channels: front left, front center, front
right, rear).

2. "Hi-Def" NTSC LDs

These were converted from Hi-Vision video masters and do in general
exhibit an exceptionnally good picture quality. They are 16:9 by
nature, as their source is. Apart from that Genesis, check out the
Sting 40th Birthday for example.

3. Hi-Vision specs

1125i is theoretical, 1080i is actual and therefore shows on any HDTV
worldwide. Not only HDTV brings us higher PQ, it also drops the country
barriers that existed in the age of NTSC/PAL/SECAM, at least at the
display level.

4. Hi-Vision hardware, LD list, info and offers:

Can be found on my web page here:

Also listed in eBay in my Discs-of-Japan store (seller n$a):

Orders, enquiries, requests welcome.


Greetings,

As others have said, it works great displaying at 1080i

They don't downscale, there is only one HDTV format, it is 1125i
theoretical = 1080i actual. You can call it 1125i or 1080i, it is the
SAME THING.

Oh, I didn't know the players downscale to 1080i. I figured they just
output 1125 and only work on some weird japanese HD format TV sets or
something. That's awesome!

I would hope that for a concert disc it's not discreet, but instead
discrete!

I didn't know if they had AC-3, but I was under the impression that
the X9 had an RF output for standard NTSC discs.

<<HiVision has

Interesting...how many speakers does this format support, and in what
configuration? Once the decoder decodes this special soundtrack, how
should a reciever handle it (pro-logic mode, stereo mode, etc...)? Can
the decoder be connected to a reciever via coaxial or toslink?

Most of these questions are already answered on my page:
http://home.q03.itscom.net/nsa/muse.htm

One simple and effective way is to connect the 5 analog discrete
outputs of the decoder to the amp's 5.1 input zone, leaving .1 empty.

Some HDTVs can exceed 1080i. JVC's 34-inch CRT HDTV can produced 1500i, which I
believe is standard for Japan (although I'm not certain). However I don't know
if anything, even in Japan, is broadcast at that resolution, and I wasn't aware
that the players downscaled MUSE discs to 1080i.

So how do I get audio for the LFE channel? And what audio mode should a
reciever be in when running a MUSE disc, Pro-Logic? Lastly, your site
says that the Victor/JVC HV-VMD1 has a toslink optical output. Is that
a pass through for the digital audio on regular NTSC discs, or is that
a digital carrier for the MUSE type surround sound?

Josh is correct. Another way is to have the 4 outputs of the MUSE
decoder sent to an external Dolby processor with such input and let the
processor make a 5.1 out of it, send this to the amp.

Answer to this is on the site as well, copy/paste:
HV-VMD1: [...] 2 optical (L'R', CS)
L'R' denotes a 2-channels mix down-converted from MUSE's LRCS.

The NTSC output of the LD deck does not go to the MUSE decoder. Which,
as you may now figure out, results in that a fully installed Hi-Vision
LD setup has even more audio cables running around than a regular LD
setup.

But my Denon always needs to be set on a "mode". If I want Pro-Logic,
Dolby Digital or DTS sound I set it to "Pro-Logic mode" and it auto
detects what codec it's getting. Otherwsie, I put it in Stereo or
"Direct" or I can set it for some sort of "simulation mode" such as
5-channel Stereo, Rock Concert, etc...If I were feeding it with the
6-channel analog inputs from a MUSE player, whuch of those "modes"
would it need to be set to?

The Denon I'm currently using is an integrated processor and
multi-channel amp, it's all in one unit. It has 6-channel analog inputs
on the back, which is what (I think) I'd need to use with the MUSE
decoder. What I'm not understanding is what "Mode" the reciever should
be set to when watching a MUSE movie. I can set it to Pro-Logic mode,
which auto detects Pro-Logic, Dolby Digital or DTS signals and switches
itself accordingly, or I can set it for Stereo, "Direct", "5-Channel
Stereo" or any of several simulation modes such as Rock Concert and
Video Game. If I were feeding it with a MUSE decoder, I assume that I
would need it set to either Pro-Logic or "Direct" and I'm curious as to
where it should be set.

Any of those as anyway it won't be applied to the incoming 5.1 signal.
You do have a 5.1 input zone, right ?
Do you have a manual, have you tried to find the answer in it ?
