Comments on news posted 2007-04-27 12:24:37: Comcast is engaged in early testing for Switched Digital Video in portions of New Jersey and Denver. The technology frees up bandwidth on cable systems by delivering fewer channels to the cable-box, keeping the rest waiting at the edge router. ..

Boy I can't wait...

This is going to be some neat stuff once it gets off the ground, because it means more channels, including HD channels. I hope all goes well with the deployment. The only problem is, I'm a rep who answers the phones, so I hope the troubles, if any, aren't so strange they cause massive confusion with trouble shooting.

How many do they need to send?

What is the lag in sending the channel from the hub? If it's only a few seconds, I'd think they could just send the channel you've selected, + 2 or 3 in either direction ( times 2 for dual tuner boxes ). Since there's a lag anyway in changing from the guide, I think people would expect that. Freeing up bandwidth can only be good..

Boundary cases?

What happens when everybody in the neighborhood tunes in to a different channel? Sure the possibility of that happening is probably extremely low, but I haven't heard anything about that boundary condition.

 Not Looking Forward to SDV

As an owner of a Series 3 TiVo, I'm definitely NOT looking forward to SDV. Reason is because CableCards are not bi-directional, my TiVo will not be able to get any channels put on SDV. In fact, unless I rent set-top boxes from Comcast, NONE of the TVs in my house will be able to get SDV channels. I guess that's more money in Comcast's pocket and less in mine. *sigh*

Well, all of the Comcast people would likely have to replace their boxes to, unless this can be accomplished with a software upgrade of all of the existing deployed Comcast cable boxes.

Of course, I'm sure the folks at Tivo would love to sell you a Tivo Series 4 with SDV.

Fiber To The Premise is the only way to go.

The only way to delight the subscriber is to bring fiber into his building.

I agree, but cable co's are not at that point yet. Coax still has many years ahead of it. There are so many things cable co's can do to free up bandwidth before running FTTH. I think you will see FTTC (Node to passive coax network) before you see FTTH..

Re: Boundary cases?

Whats the error message now ?

"Please wait while we make this channel available" ? Some thing along those lines ?

Re: Not Looking Forward to SDV

All digital cable boxes have rf return and some use telephone returns. So when it requests authorization to tune a channel the SDV kicks the channel on and down it comes.

The cable card can't make that request. So It's stuck.

My guess is 2 way cable cards will have to be rolled out in the areas they put this in. So your tivo may need a software upgrade. But should work.

The way my wife surfs . she will stress the network out with in 15 minutes. Then maybe I can get dish networks full package again.

I'm assuming it'll be similar to Satellite or IPTV(multicast delivery)

With my IPTV it generally takes less than a second to tune to the channel

you learn pretty quickly that you can't really channel surf like the old analog cable days, but you become more accustomed to just using the mini guide, and scrolling thru the names of the shows on to choose what to watch

Sounds like messaging straight from Verizon marketing

FTTP stands for Fiber To The Press release. This is mostly hype and the smart techies know it. If fiber to the home is needed today, why aren't homes wired with fiber? Why are most office drops still twisted pair?

Copper and COAX have a long way and many technology advancements to go before home capacity requires a new media. Then, and only when it is needed, the fiber becomes deeper in HFC. Anything other than that is wasted capital for anyone other than telco's with 50 year old infrastructure.

Re: Not Looking Forward to SDV

According to the folks at the TiVo Community forums (»www.tivocommunity.com), two-way communication can't be implemented in software. Hopefully someone can build an external device (maybe USB) that can enable two-way communication. Otherwise, I'm stuck.

It's not the CableCard that needs to be bi-directional, it's the hardware it's installed in that needs the 2-way communication channel back to the headend.

CableCards simply are for decrypting the encrypted pay channels.

SDV will affect the free channels you receive without CableCard as well, because the hardware receiving has no 2-way communication. But since the free channels are likely the most popular channels, they will not be put on SDV, because there would be no bandwidth savings.

There are cable boxes now that use current CableCards that support 2-way communication. They have a DOCSIS modem in the box that does the 2-way communication. The CableCard is just decrypting the pay channels, as it does in any CableCard device.

Enabling 2-way communication requires new hardware, not a new CableCard.

Doesn't the Tivo Series 3 have an internet connection? I think that it would be possible, by Tivo in cooperation with cable providers (and maybe CableLabs), to work out a software interface that would permit the Tivo to initiate channel change requests out the ethernet to a server at the Cable Company. That server would handle the requests in the same manner that they would from a DOCSIS-based return set top box.

Needs work - but it can be done.

SPEEDS ?

This process sounds interesting but how will this effect bandwidth up and down?
