Re: Faster internet but same prices for cable TV
have you ever written a check to a programming provider for a viewership of 1.6 million? Try figuring out how much you need to pay the food network and then discovery channel x only those customers who subscribe. Not just an addressability thing. |

cable companies don't DWDM their forward plant signal. The only reason they would is if they had two cable plants. One for the 1490 lambda and one for the 1550 lambda. It would be useless to DWDM a fiber when it is destined for one coaxial cable. |

dude, you're making me sick. You obviously no squat about TeleVision Recieve Only, A-Synchronous Serial Interface, Multi Program Transport Streams, Motion Picture Experts Group Version 2 Numbers, Digital Multiplexors, Gigabit Ethernet Interfaces, Small Form Factor Pluggables, Cisco, Small Form Factor Pluggables, Smartstream Encryption Modulators, Digital Encryption Standard, Two Hundred Fifty six Quadrature Amplitude Modulation, Dense Wave Division Multiplexing,Fiber Optic Transport Mediums, Optical Network Terminals. Do you have a "duh" key on your keyboard? Or maybe an "anykey" to continue what you were doing before you started posting your uninformed knowledge? Spend your time elsewhere like a lemonade stand, you'd be seeing more people who are at the knowledge level you are obviously showing.
P.S. you're welcome for the class on acronyms

said by G_Poobah  : Again, ZERO technical reason you can't belong to a single channel group. And again you still miss the point! Delivering single channels has NOTHING to do with the technology. Cable companies have been able to do this for at least 15 years now. Where have you been?
Delivering singles channels can be done with anything from Analog cable to digital cable. In analog, they have to scramble basic and deploy settops. The box drivers can be sent channel and service masks that authorize single channels.
Same can be done with the digital cable too. As long as a system is addressable, it can be done. The reason it's NOT done is because it's not financially feasable to deliver service to the masses on an ala carte basis. Those choosing single channels wanting a couple of channels would be wind up paying the same rate as basic cable at about $3.00 or so per channel. And, it would cause the basic and digital tiers to increase as well for loss of viewship and advertising revenue.
It's obvious you have some degree of insight into technical jargon - don't know if you are just quoting stuff you have read or if you have some level of first hand knowledge, but it's obvious you don't take in the whole world of television which is important if you want to justify your point. |

said by G_Poobah :umm, not IPTV? I'd be very very interested to know how you can send an analog signal over fiber. Yes, it IS IPTV all the way (IGMP to be specific). There's no 'analog' signal on fiber. Video on Demand is RTSP or some proprietary cisco crap. In fact, if you want analog, they have to install a DAC converter in your house. FIOS TV is a multicast IGMP signal, and the headend box is configured to decode the appropriate signals to display on your TV, depending on your group membership. Channel selection is ALL configured at the central site, which broadcasts the keys for your personal box so you can decode a channel. Again, ZERO technical reason you can't belong to a single channel group. Well I guess the above posts may have had you change your mind. I have done contract work for verizon and your idea's are not how they are doing it. But it was really fun to see ya shot down so quickly and proven wrong with out me even having to be present.

Actually you very wrong. Verizon FIOS TV is not IPTV. It's an RF overlay. In essence what Verizon is doing is they extending the node all the way to the customer home. The OTN node they install for FIOS converts digital TV feed to RF. Reason for that is that Verizon wants to reuse the existing coax cable inside the house and they can use existing cable set-tops from Motorola (like DCT-2500, DCT-6200 and DCT-6412) without too much modifications. It's a relatively simple and elegant and less expensive solution than end-to-end IPTV.
The fiber that comes to the house can carry multiple multiplexed wavelengths. One for video, one for data and one for VoIP. Just like the cable companies do. |

wmcbrine is spot on about the experience being mis-leading..I jumped to the same conclusion when I heard FTTP was coming my direction. Good reading re: FTTP / VPON / IPTV

said by G_Poobah :umm, not IPTV? I'd be very very interested to know how you can send an analog signal over fiber. The same way as you send any other signal. There's nothing intrinsically digital about fiber. It's just modulated light in place of modulated electricity.
Experience is misleading in this case, since everything light-based that the average person has encountered has been digital -- CDs, DVDs, optical digital audio, sometimes networking. But it doesn't have to be that way. Recall the analog video of the original 12" laser discs.
And even if it were digital, that wouldn't necessarily imply IPTV, either. Digital Cable and OTA ATSC are digital, but not IP-based. |

Still the "Analog" portion is about 20 channels.. anything more and you require a STB.

LOL, you are too quick for me mischaej 
Historically, most of the video distributed by CableCos and others over fiber has been as QAM MPTS's over 6 MHz analog channels, just because it is the much ballyhooed, mythical elixir called "fiber", does NOT mean it is by default "digital".
It has been only relatively recently that video SPTS's have started to be distributed as IP over a switched data network (usually GigE fiber).

It's called CATV HFC Emulation. They use a wavelength of fiber and dedicate it to the TV section, and from there simply transform it from Fiber to Coax.
»FiOS CAPEX, why not IPTV, VoIP, Data and No ONT
Any respectable cable co in 2005 uses fiber in some part of their backhaul, all verizon is doing is bringing that backhaul to your doorstep |

said by G_Poobah :Which goes to show you once again that it's greed, not what the customer wants driving the change. This is FIOS. There is now officially ZERO technical reason they could not sell you a single channel at a time. ZERO reason at all. It's digital, it's not even SENT over the wire unless it's ordered. There's no chance of 'theft of service', etc. So what's their justification for forcing someone who wants to see the Discovery Channel having to buy ESPN2? Greed, plain and simple. Though I generally despise the government, I would love to see the companies put in front of the nation, and be forced to defend their practices. They no longer have any technical reason to say they can't provide ala-carte pricing/packaging. They are providing 15 channels for 12.95. Why can't I choose the 15 channels I want for 15.95? Really, even with 160+ channels, there have been tons of studies that show people only watch 15-20 channels. The only reason they bundle them all is simply greed. The tv portion is NOT IPTV. It is always present. The PPV is like IPTV and on demand.
