Re: FiOS TV Features Update
Does anyone know how Verizon TV is going to handle the upstream path for things like PPV ordering? Is it going to require a phone connection? |

No, no phone connection. It will travel over the same bandwidth allocated for transmission of video. Video (CATV) has an allocation of bandwidth, phone has an allocation (up to 4 POTS lines), and data also has an allocation (supposedly up to 100Mbps from the start). There is also plenty of bandwidth to spare should Verizon decide to offer other nextgen services or bump up bandwidth to an existing service. |

So am I right in thinking that the coax path from the STBs to the ONT will be bidirectional, but the video path over fiber is unidirectional (since there is only a single wavelength laser for video). If so, I assume the ONT relays the STB upstream information onto the same datapath as used for upstream voice and internet. |

According to their marketing video, the video spectrum "dedicated" to video is 860MHz.
How does that compare to Comcast or Cablevision's coax lines? you guys tell me... |

Well I would say that it doesnt. Its far superior considering that Comcast and Cablevision operate 750MHz systems that share voice, video and data, whereas Verizons 860MHz is all video. |

| There's a radio ad I've heard here in Tampa FL which is designed to get consumers to push their local government to approve the addition of the new Verizon TV service. In that ad, they mention 'video conferencing'.
Any thoughts where/how a two-way service like video conferencing fits in? |

most cable companies are 750 with most being 860mhz |

Can you imagine a image sensor and microphone on the STB to video conference using your STB and TV. Thats a great ideo, are any STB manufacturers planning on doing this?
Then you dont have any need to buy new telephones and waste money on lcd screens for those telephones. |

DMS1,
No, the coax path from the ONT to the STB is unidirectional as well. There is no "reciever" on the RF side of the ONT. The ONT does indeed relay all information from the STB upstream via the 1310nm return path used for data and POTS, however connectivity is achieved through an ethernet return path from the STB to the ONT. |

Can you imagine telling people signing up for FIOS TV that 2 cables will be needed per tv? Sorry that is probably one the of silliest questions posted on this forum to date |

I asked the question in response to Mannix16's reply saying that there would be an Ethernet return path from the STB to the ONT. I agree that forcing people to install Cat 5 would be silly. Please enlighten us to the actual solution. Is it wireless? |

| The Motorola ONT uses just the coax: »www.motorola.com/content/0,,5537···,00.html
To date I haven't seen anything making it clear how the Tellabs ONTs handle the video return path. Of course the 611 (Vinci) ONT is the only one I've ever found any sort of datasheet for.
It might be interesting to see what this says about the return path: »www.itu.int/md/meetingdoc.asp?ty···5-C-0013 |

| Yes, the Moto unit (not in the field) has a return path on the coax. Indeed many "not in the field yet" ONTs have coax return paths. However the 610s and 610Xs in the field now do not. As of now, with a 610x, you would get regular/basic TV throughout the house, but if you have a TV with a set-top-box for VoD, PPV, or DVR, you will require an ethernet return path for these TVs only. I'd expect to see coax return paths (in the field) in the not to distant future, however this is not a critical feature as it will take Verizon some time to get their video service off the groung anyhow. |

| We'll just have to wait and see how the return path is implemented... but...
I expect that early field trial units will use a separate Cat5 path.
Later field trial units may mux the ethernet signals onto the same physical coax and demux in or near the ONT. The mux/demuxer might be built-in or separate little boxes.
There is at least one company www.coaxsys.com that specializes in equipment designs that allow for Ethernet packets over ordinary TV coax... |

| No I don't. I am very familiar with PON technology itself, however am I less aware of how the Telcos will use it, as it is a very flexible system. If I had to guess, I'd guess yes. If you can have one digital cable box in your house, but still get analog cable on the rest of the TVs in your home from a cable provider, I would assume Verizon would like to compete on that level as well. |
