I'm going to be outfitting a 10 floor hotel with an HDTV system. They have a Com 1000 at present, but that contract is expiring at the end of this year and will not be renewed, and so I can either give them a similar system with a few more channels, or I can give them something else, if there is a something else. I did a lot of commercial work a decade ago and I even got a Level 3 certification back before they thought to issue installer numbers (1998, I think) but because I now only get involved with hotel systems once or twice a year, I don't bother to digest all the new product literature. Their biggest constraint is that they use loop riser wiring, which limits what signals I can deliver to each room in two ways: it can't support so-called "legacy" multiswitches, and it has too many receivers per riser wire to be serviced by SWM, even if I upgraded the taps (are there now approved SWM directional couplers?) and if I could manage the signal power over those lengths. This hotel is not going to home run wire in a manner that would support DRE or any other conventional L-band distribution. A year ago, there were rumors that DirecTV was going to develop something like the SWM but that used the cable TV band. Did anything ever come of that? I remember thinking at the time, that if they made a cable-band SWM and if they staggered the return signal frequency just a little so that it would not be incompatible with the current SWM return signal, then maybe they could be combined into a single riser wire that has a few more than eight drops on it, by putting the L-band equipment on the nearest few drops. I've serviced dozens of ten story hotels that would benefit from such a system. But if such a product existed, I think I would have heard of it by now. I'd say that for now, the most I can offer them for an upgrade is digital on the standard def channels. Last I knew, a few manufacturers were making clear QAM encoder/modulators that put the outputs of four A/V sources, like D12s, onto one cable channel. Is that still the state-of-the-art technology, or are there now any products that put more than four on one channel, or that bypass the needlessly cumbersome digital-to-analog-to-digital architecture of doing it that way?
