That's not too bad, except you'd have to fit in 100 mpeg encoders into the system (not that unreasonable). You might be able to record the whole thing on a computer with a generic Digital to Analog converter, split it up in software and then reencode in mpeg, don't know how much processor power / bus bandwidth that would take.

I imagine any amount of secure encryption would really hurt people trying to play bandwidth-heavy games.

Cable companies that implement DOCSIS 1.1 can use something called Baseline Privacy Interface, which essentially provides for just that. Cox Communications (as an example) has turned it on for most if not all of their cable systems. BPI provides for encryption from the modem to the CMTS (where the cable system meets the rest of the IP network, essentially). I used to work for Cox, and I don't recall hearing any complaints at all in terms of speed or latency issues. A few modems here and there balked at the config changes, but those were issues with those modems, and nothing inherent in BPI or DOCSIS 1.1. Of course, BPI only works (I believe) if the modem is DOCSIS 1.1 compliant or better. Older modems won't be able to use it.

Depends on what you consider practical, I guess. I would say no. Your typical TV or VCR has one or two receivers or tuners in it. A receiver or tuner is capable of receiving or tuning a single channel at a time, so a dual-receiver or dual-tuner TV or VCR is capable of extracting two channels at once. Software-defined radio (the same principles apply to receiving channels on a wire that they do to receiving channels over radio waves in the air) could, in theory, receiving the whole spectrum at once and extract individual channels out of the stored data at a later time. Again, it becomes a question of what you consider practical. Or with a fast enough processor (does it exist?) controlling the tuner, sample each channel in real time, like a couch potato surfing through the channels and getting a fair idea of everything that's on, only much much faster. It'd have to sample all 155 channels (or whatever) each 30th of a second (for analog TV signals) in order to get a full 30-frames per second for 155 channels. But that's probably closer to the theoretical rather than the practical. It'd be pretty hard to do it quite like that, with one analogue tuner continually being retuned. You'd have to tune it through all 155 channels every 0.125us to get a 4MHz video bandwidth on each channel. As a side effect the selectivity would be reduced and adjacent channels would interfere with each other. You could ease the task by only trying to recover the audio, perhaps at less than the full audio bandwidth. Better to do the whole thing digitally - A-to-D the incoming signal directly and have a fast DSP implement 155 tuners and demodulators in parallel, in software. That's less impractical than it sounds. GPS receivers work vaguely like that, to receive several satellites at the same time. DAB receivers are also vaguely like that, to receive the multiple carriers of the DAB signal simultaneously. Both cases are less demanding, of course, but it's certainly possible in theory. In practice you'd probably have to use a combination of software and hardware parallelism - eg. 15 DSPs doing 10 channels each - with current processor technology.

Charter in St. Louis has been excellent; barring one problem which their support immediately recognized and came out to my neighborhood to repair, I have never had any noticable downtime and the connectivity has been superior. I believe they outsource their news, mail and web hosting services from Earthlink, but as I don't use it for that, I can't comment on the quality. You might also consider talking to a group local in your area; I've found that some St. Louis-area user groups can be helpful after sending a quick mail to their respective mailing-list. -- scott c. linnenbringer | [EMAIL PROTECTED] http://www.moslug.org/~sl | [EMAIL PROTECTED] pgp0.pgp Description: PGP signature

Sure you just need to tune in to a wider range of frequencies. Could it in practice? Let's assume there are 100 channels. That means that if you wanted to do it with analog technology, VHS, you'd need 100 times the capacity. Either 100 tapes in parallel (imagine having to synchronize 100 VCRs), tape rolling at 100 times the speed (tape would wear out, each tape would last 2 minutes instead of 2 hours, etc), tape 100 times as wide (lol, just try to imagine that), or a combination of each (twice as wide, ten times as fast and five in parallel),or of course a better technology. If you were doing it digitally, mpeg capture, then you'd need a tuner per channel each capturing at about 1 mbit/s. So that's about 100mbit/s or about 8 megabytes of video per second. That's not too bad, except you'd have to fit in 100 mpeg encoders into the system (not that unreasonable). You might be able to record the whole thing on a computer with a generic Digital to Analog converter, split it up in software and then reencode in mpeg, don't know how much processor power / bus bandwidth that would take. So the answer is yes it's possible but it probably woulnd't be trivial. Bijan -- Bijan Soleymani [EMAIL PROTECTED] http://www.crasseux.com signature.asc Description: Digital signature
