|
|
Hi
Will a HD DVD player playing a Hd DVD that is only connected via SVHS look better than a normal DVD player?
With all the cheap HD stuff around a friend asked me if it was worth it.
Thanks

Connected only to a SVHS machine? Seems in insane way to do it and a rather silly question. I doubt the SVHS will pass the HD signal at all - it's SD, you know, with no downconverting capability - so my answer would be no, it would not be worth it to try. But it's easy enough to attempt; just do it.

I think he mean's via an S-video cable. So he'd be getting 576i, I think.

Yes, a CRT TV with only SVHS input.

Unlikely. A regular DVD is encoded at 480p, which is already higher bandwidth than s-video can handle.

I wouldn't bother. Why would you want to put up with the 1-2 minute load times to watch stuff on a small TV that in the end wouldn't look any better than on a regular DVD player since you're using S-Video?

SVHS = Super VHS (ie: a VHS tape recorder that records in stereo)
You mean: S-Video which is a connector type.
More information here: http://www.curtpalme.com/CRTPrimer_17.shtm
S-Video (Analog, limited to 480i)
One step above a composite video signal. Relatively speaking, I’d say that an S-Video signal is about 25% better in picture detail than a composite video signal, so wherever possible, use an S-Video feed to send to the projector over a composite video signal.
Use the S-video connection will get about 20% more detail (my estimation) over a composite video connection.
Due to the black and white and chroma (color) signal being run separately within an S-video cable, the general recommended length of an S-video cable is limited to 30 feet or less. Longer runs will show that the black and white and color images will not overlap completely on the screen, and the color portion of the signal can lag the black and white one by ¼" on the screen. I’ve seen this happen in one of my own installations, and the only cure is to use a shorter S-video cable (or buy a very expensive S-video signal booster with adjustable phasing controls on it). It is very easy to bend one of the 4 pins on the S-video cable, take care not to bend a pin, or a loss of picture or color will result.

Sorry Kal but you are wrong on the SVHS.
That does not mean stereo VHS.
It stands for Super VHS which does look way better than regular VHS but not quit as good as DVD. You can not play something recorded in SVHS on an ordinary VHS machine but the Super machines would play a regular VHS.

But regular VHS is stereo. Only first players and later cheap players were mono.

But I didn't say that. I wrote:

Didn't know it was a completely different standard however with increased resolution. It is stereo though (whereas VHS is not).
Kal |
VHS 250-280 lines or resolution
SVHS 400-410 lines of resolution
Stereo was first added to VHS in the form of linear stereo edge tracks that were mono compatable. Many of these systems used Dolby B noise reduction. Later on VHS came out with the HiFi sound recording. This lay's the HiFi sound tracks on the tape with helical scanning between the blanking interval's of the video signal.
(IIRC I read that back in 1988 in Video magazine)
S-video connections were used not only by Super VHS machines but also LaserDisk, ED-Beta, Hi8 and of course DVD. Some manufactures took to mislabeling the S-Video jacks S-VHS which has caused some confusion.

LaserDisc never came with S-Video. Composite was the best connection on LaserDisc machines.

This is WRONG. Most LD players after 1989 had Svideo. Although most preferred the composite over svideo.
Plus, my LD-S9 had Svideo.
from Wiki:
| Quote: | | Many Laserdisc players manufactured from the late 1980s through the time of the format's death had both composite (red, white and yellow RCA type connectors) and S-Video outputs on the rear panel. When using the S-Video connection, the player would utilize its own internal comb filter, designed to help reduce picture noise by separating the luminance (brightness) and color parts of the signal, while using the composite outputs forced the player to rely on the comb filter of the display device. Although using the S-Video connection was often considered to yield superior results in the late 80s and early 1990s, most of today's mid and high level television sets contain better comb filters than the vast majority of players were equipped with. In these instances, where a player is being used with a more modern display, using the composite output and allowing the display device's internal comb filter to do the work may yield better results. |

All the great info posted so far aside, (albeit related to aged technology), I'm curious....are HD players made with an SVID connection??? (It's Monday...my designated gullible day) I wouldn't think so... but I only have the XB360 drive so wouldn't know. I can't see any logic in it but stranger things have happened....like Blu-Ray beating HD-DVD for instance.  (ducking).

All 5 of mine have S-video, the oldest being a Sony from 1993. Granted the LD was encoded with composite video but I found on my systems S-video looked the best. Especially on my Sony 27" TV who's dot crawl was legendary when running composite.

I have two laser disc players (same model) that have component video out.

The reason you have component on your Laserdisc Players is because they are LD/DVD Combo players.
You will not get a laserdisc picture out of those component output only DVD.

The Toshiba HD-A2 has composite out! It's handy for making initial settings (resolution, etc). It doesn't have S-Video out though. I think.

That wouldn't be because you scarfed up a thousand beta porn tapes from the last format war would it?  
dculberson- Thanks for the answer. Wow...I never would have guessed they had composite and not SVID.
