"But just for the sake of argument, say they allocate 72MHz out of that 200MHz for VoD. This would give 12 6-MHz channels, within which they could pack 10-15 VoD (SDTV) subscribers (per 6 MHz channel)simultaneously. Let's call it 12. That would enable 144 simultaneous users." ftth- Thanks for the general notes about VOD and the HFC architecture requirements. I'm just starting to understand how this all works, but I'm still a little confused. Regarding your excerpt above--I thought that a single 6 MHz channel was good for only three SDTV signals. Why would the MSO be able to stream 12 discrete video streams down a single 6 MHz channel? In other words, wouldn't 72 MHz you estimate for argument purposes be capable of serving only 36 simultaneous users? ____________ I noticed I did a typo in my comments about number of subs per hub. I wrote 500 but this is not accurate at all. I meant to say 500 subs per node. And I see this is an important consideration as I read your notes. Can you tell me what is the average number of subs per a typical hub in a modern 750 MHz plant? I've read quite a few figures that peg the number of subs per 'node' at around 400-500. But I don't recall ever reading stats on the number of subs per hub? __________ And here's a wild hypothetical question that will help clear up some confusion on my part. Say the MSO has unlimited budget to purchase VOD servers. Say they go out to a particular hub and want to be able to support 100% of the subscribers connected to that particular hub with simultaneous VOD. Say they purchased 1,000 servers and placed them in that hub. I'm assuming there is no WDM available. Just the typical current fiber out to the node and typical coaxial drops. And I'm also assuming your figure of 72 MHz allocation to VOD services is still in place. Would 1,000 servers make this goal of 100% simultaneous VOD users possible? _____________ "Or do they "push" a software download to your STB to enable it?" No extra fee for VOD. No truck roll(except for the time I switched to digital services from analog months ago). A few days ago, they pushed the software down to my box. One day I had no VOD. The next day I did. _______________ "...and all I want for Christmas is for @HOME to get their email running reliably for more that 24 hours straight!" I know exactly what you mean. My cable modem spits and coughs all the time. It's pretty annoying. So I'm just totally perplexed at how the same MSO is able to insure that my TV signal is not giving me the same fits as my CM does. And I'm especially concerned they will fail on the VOD as you would think delivering a consistent Internet connection would be much easier than delivering a VOD signal. Maybe delivering a discrete VOD SDTV signal(with VCR like controls) to my particular STB is easier than an Internet connection?? Thanks. -MikeM(From Florida)
