huge thanks for that; must admit i, for one, didn't know about it (no trade journals, alas!).
as i understand system, receiver still gets "chosen" channel via standard tuner, which means that complete mutiplex. There's approx 30 "slots" in 1-2 Ghz, so you can connect 30 receivers to 1 cable, after which there's "blocking probability". To guarantee 120 receivers can get all channels, you're back to 4 trunks again! Once the whole thing "packaged", I'm not sure it's any cheaper or better than existing multiswitches. Might be though with volume production. Probably ideal for in-flight entertainment.
Then there's new diseqc ICs and extra software, will take some time to get established.
If you could interconnect the chips digitally at very high speed, with single optical fibre, now that would really be something! But again, probably too expensive for existing applications. But, clearly, "it's the future" .... |
