With only 32 (RX & TX count as one channel per sub) channels per Passive Optical Splitter, again, Verizon is limiting their service as I stated before to their sub's. Unless they change the delivery to a IPTV or SDV type delivery, which also means changing out millions of boxes, due to the only thing that currently is IPTV on CATV & FiOS is the App's if there are any, and OnDemand. Everything else, eats up Qam channels.
At 2 to 4 HD streams, max of 6, and with up to 12 to 16 SD channels, there is only so much they can push through the system, since they are pushing all channels downstream to all customers at the same time. Unlike UVerse, where the IPTV service only sends out a channel stream, when a customer tunes their IP STB or DVR to that channel, and in turn the VHO sends down the IP address for that channel to the box. If multiple customers on the VRad are watching say NBC, the VHO will only send one stream for NBC to the VRad, and then the VRad will send the signal to the boxes tuned to NBC. In turn you are not choking the system, because you are not sending multiple streams of all channels regardless if they are being watched or not.
I find it entertaining that you're arguing with me when you are flat out wrong.
You are now just stating random facts about FIOS, and not addressing what you were saying before, which is wrong.
The point we are arguing here is not whether FIOS has a capacity limit (IT DOES), but whether it has a higher limit than cable. It does have a higher limit than cable, because it has the same 860mhz system, but ZERO internet, VOD, or phone service in that 860mhz, only linear channels.
I know how FIOS and U-Verse work. U-Verse's limited bandwidth to the home is why it can only handle 4 HD's at once, and why the picture quality is so atrocious, but also why it can offer a lineup of nearly unlimited size of horribly over-compressed channels.
Verizon's QAM system has limits, but with MPEG-4, the limits are likely larger than the number of HD channels Verizon can buy to put on it. With 810mhz of usable bandwidth, from 50-860mhz, you get 135 channels. At 5 HD's per channel, and say 10 MPEG-2 SD's per channel, you can take 300 SD's, and still have 105 channels left for HD's, which is 525 HD's. I don't think there are 525 HD's. Even with MPEG-2, they have a metric assload of bandwidth for HD's.
FIOS is also unique in that they have the capability to switch to all IPTV, and in fact much of the existing hardware would still work in an all-IP world, of course not CableCard boxes.

Please stop making blanket assertions as if you know exactly what is going on for everyone. You're doing the same thing over at TCF and it really takes your cred way down.
I missed this post yesterday. I guess I should have been more clear. They triple channel everything they can. Theoretically, they should be passing OTA signals on straight through with each OTA channel and all its sub-channels in half a QAM, I'm not sure if they are. And a couple of channels, like ESPN and HBO mandate bitrates that you can't get through triple-channeling. They are now, however, giving them a full half-QAM, they're probably doing 2 HD's and a couple SD's, so that it's like a 40/40/20 split, with 20 being SDs, instead of a 33/33/33 dynamically encoded split.
