The "only way"

I didn't know that TW had eliminated 100% of their analog channels.

Depends...
said by Joe12345678:

At what point is the SDV split done the headend? the node?
Headend. It's where the data transport ends and the distribution begins anyway. It's the choke point where the cable company has to decide and generate what to send down the smallest pipe in their network. It's where the RF channels are created.
said by Joe12345678:

What happens when there is not room left channels that are need in a area?
Customers and server logs get an error message. Network management should be monitoring such events for repair or upgrades.
said by Joe12345678:

Things like that may end of stopping cable from having 200+ hd channels?
Why? It's possible they could also just go IPTV and send just the channel requested. Without SDV or IPTV, they can't even get to 200+ HD channels because of all the other channels demanding RF spectrum.
said by Joe12345678:

Will all channels be on SDV or will some high use ones be on all the time?
Only the channels the provider setup are on SDV, it doesn't have to be all of them. It could be a handful. It could just be the PEG (public, education, and government) channnels they're mandated to carry but everybody claims never to watch... or it could be shopping channels or Hallmark and Wealth in a college area or G4, Playboy, and SciFi in a senior citizen home. It really just depends on demand.

You'll never hear FIOS say "We're totally out of bandwidth!"
Verizon has been in a major hurry to ditch the analog channels they carry on FIOS and pretty slow to add HD channels. With the current FIOS setup and design, they're limited to the same 860 Mhz RF bandwidth for TV that channels many cable providers are... so "totally out"? No, but the limitations they've run into has caused them to change their plans and look at IPTV in the not too distant future.

It's all the talk here:

said by Joe12345678:

Depends on the engineering. In a non-switched system, every possible channel is transmitted to every house. That's what, 100 or two hundred channels?
said by Joe12345678:

At what point is the SDV split done the headend? the node?
Wouldn't make sense to do it at the headend. Presumably it's done where ever the system transitions from fiber to coax.
said by Joe12345678:

Things like that may end of stopping cable from having 200+ hd channels?
You don't need a separate channel for each house, just each channel being watched. Clearly they've done the analysis that shows that subscribers on a given node are unlikely to exceed the bandwidth available.

Anyway, SDV is just an interim step until they install fiber to the neighborhood or house.
said by Joe12345678:

Will all channels be on SDV or will some high use ones be on all the time?
What purpose would it serve to be broadcasting a channel noone is watching?

Well clearly...

It's in the cableco's best interests to not have folks using their own gear.

TiVo is unfortunately caught out in this. They have the best UI no question, but when you have to piggyback onto the provider's network you have a serious control problem.

TiVo states they're working with the cablecos to come up with a solution, but it shouldn't be too hard to figure out that there isn't much motivation for the cable industry to have that solution in place.

TiVo's best bets are more device partnerships like they are doing with Comcast but hey we all know how long that's taking to roll out.

It's crap but it's getting to be harder for me to continue supporting TiVo just because of the inconvenience.

The cable industry shouldn't be responsible for Tivo's slowness. It's Tivo's responsibility to their customers to keep up with the cable companies.

TWC shouldn't have to wait to rollout SDV when it's Tivo's fault for not putting out two-way hardware.

No, it is a TWC issue. They give people flawed hardware. Most cable boxes do not suffer from this problem. I can't wait until the day some kind of drm screws up right in the middle of the superbowl. That might actually get people to fix things.

Re: How much space does SDV free up in a high use area?

With the amount of Digital Channels that are used in a node at any given time, I'm almost certain that you won't saturate the node. I believe it was about, what, 20 channels per node in use at any-one time? Or was it 20%. Either way, the digital tier is used so little as compared to analog it's not a problem.

Re: That is one hell of a downgrade

If it were a TWC issue, other connection types would be similarly impacted. They're not. It's only HDMI. And as I said, other devices have similar problems with HDMI.

HDMI is the culprit. In their haste to lock down the "perfect connection", issues were created with the convenience factor. It's almost better to use Component and optical so you don't have to deal with that crap.

In other words, to make some extra dough before the fourth quarter, and to help cover the costs of switching to SDV, TW wants owners to start paying for a STB.

Are they planning on giving the 1200 customers free set top boxes to replace their Tivos? After all, it's only 1200 customers, a 'small' number.
Those should be FREE DVRs not just FREE STBs since that is what replacing a Tivo needs to be an equivelent swap - you need to get a DVR not just a STB,

If the feed to the STB were upgraded from IPv4 to IPv6 then the SDV type channels could be sent via IPv6 Multicast which would automatically allow only one copy of the content to flow to a Node and would prevent that content from going to any Node where a STB is not tuned to the channel.

There is nothing on the www.twckc.com web site indicating most of those changes. The only indication is that next week, the rest of the HD channels (outside of local channels) will be moving.

Now, I will admit, I'm definitely liking how it is easy to remember the HD channels = 1000 + SD channel number so TNT is 32 and TNTHD will become 1032.

When they are adding Weather Channel HD?

Re: That is one hell of a downgrade

Other connection types do not have hdcp. That is why only HDMI(which is dvi) can be effected by a terrible implementation of it. And only syncing with a device when the box is initially turned on is a flaw. Switching between inputs doesn't work with TWC's junk.(Although I wouldn't consider that a valid solution either)

Re: How much space does SDV free up in a high use area?

That has nothing to do with it. The amount of channels will still remain proportionate to the amount of bandwidth they expect to reclaim with SDV. When you consider that they will stuff about 6 to 8 analogs into one frequency. Take a 70 channel analog basic and stuff that into digital, you'd reduce the analog burden by about 57 to 60, depending. Even if you had every typical analog in use and the 20 digital in use, you'd still only be using about 15 frequency slots in anode which is far less than before.

The fault can go multiple ways, box, tv, guide... including the cable in between too.

It's possible the TV has an issue with the HDMI signal the box puts out, even if the box signal correctly follows the HDCP spec. It's possible the TV is NOT communicating with the box correctly during the sync.

See the Fios TV thread regarding Samsung TVs and their boxes as an example...

or read this:
»utahtechinfo.com/video/hdmi.html

or this:
»www.popularmechanics.com ··· 233.html

or this:
»www.avrant.com/?p=194

HDCP over HDMI is by no means perfect, even if everybody is following the same spec. Component connections are far more reliable...

Either way though, it has NOTHING to do with Tivo users not being able to use SDV.

Re: Well clearly...

If Tivo wasn't such an arrogant company and played nicely before, we all would have an option to have Tivo on cable company's box. I think it was the biggest mistake Tivo made -- by not trying to get into cable company's hardware and waiting until they "crawl back to them" asking for a better deal. Instead it's the Tivo that did the crawling and still it has no agreement with Time Warner cable...

What's wrong with IPv4 IPTV multicast?
Simple.

With IPv4 Multicast EACH user has their own SEPARATE copy of the session between them and the Multicast Server. IOW: It is the same (ie: Equivalent to) as each user doing their own FTP Download of the stream. Thus if there are 1000 users turned to the same channel who are talking to the same Server from my Node (or Nodes that share the path to the Server that my Node is using), there are 1000 sessions and thus 1000 copies of the content flowing eating up bandwidth. Think of it like 1000 phone calls listing to the same one-way conversation.

With IPv6 Multicasting, there is one Session per Node which each user is monitoring (the User's End is a IPv6 Multicast IPN like the old IPv4 Broadcast IPN [1 bits in the Host Section of the IPN - Ex: For a /24 IPN the Bradcast address is x.x.x.255 and all nodes in the x.x.x/24 subdomain listen and hear the session]). If there are 5 nodes that are receiving the session from the Server, there are only 5 sessions with data flowing not 1000. Think of it like the old Telephone Party Line.

As an analogy, it is the difference between 1000 people driving to work and these 1000 people using buses to get to work which start at Park&Ride Parking Lots. The same 1000 people use LOTS LESS vehicles between work and the Park&Ride lots.
