Re: If I just get FiOS TV do I still need a broadband router?
said by av3: It's most likely less cost effective. It would require another wavelength of light for the RF upstream channels, some method of multiplexing/demuxing the upstream/downstream RF channels onto and off of the Coax, a modulation scheme to time multiplex the data going onto the upstream wavelength so only one ONT is sending at a time, and then corresponding equipment on Verizon's side to do the reverse.
So the difference between a Comcast DVR and a FiOS DVR is that the Comcast ones have a built-in broadband modem so they can talk directly on the coax to Comcast servers for guide and on demand? I wonder why FiOS didn't do it this way too?
They could've taken DirecTV's approach and send the guide data on subchannels at all times and have the box periodically update from that stream, but then VOD still needs a return channel. DTV used to use a phone line for PPV.. and who wants to do that anymore? Not to mention that VOD would then take up QAM slots on the coax, where Verizon is already very limited due to their high picture quality.
They already have a dedicated, very high bandwidth channel for data and their internet service. Why not just use that?
