In Reply to: Long cables posted by Vaughn3D on October 21, 2002 at 06:14:44:
In spite of SamM's good fortune, there are problems.
1. Signal strength.
2. NoiseI, too, have run 8 metre S-video cable (from Laser Player to Projector) and it worked well, though I found that the routing of the cable in the room made a significant difference in the signal quality. I should point out that this was in Manhattan, a veritable soup of interference.
Various people make video boosters/amplifiers to help in the signal strength problem. There are usually some for sale by Audio Advisor and probably others inknown to me.
Thay ain't cheap, however.
Follow Ups:
the underlying assumption is that you should always start by using the best quality s-video cable you can afford and then go from there, since shielding is obviously an important factor for such a long run.Sam
As we did. Nevertheless, the signal strength problem does not go away. It is not dissimilar from the constraints in VGA cable runs. As always, the problems are far more obvious in a projection system (mine was +/- 72" in Manhattan). As to cable quality, the better cable was obviously better than other remedies, in fact it was better than a lesser cable running 1/2 the distance. Sometimes (only sometimes) there is more to cables than fairy dust and hype!As an aside, Composite video (ugh) fares better over long runs, all things being equal. That is not to say one would prefer the composite feed (though in LaserDisc players that becomes a shootout amongst the competing comb filters and their synergies with cables and other "stuff").
