TiVO users in SDV markets gets some good news...
(old news - 10:31AM Monday Jul 21 2008)
tags: Video · business · hardware · bandwidth · cable
A growing number of cable operators are deploying switched digital video (SDV) technology, which frees up bandwidth on cable systems by delivering fewer channels to the cable-box, keeping the rest waiting at the edge router. In current cable systems, all channels are consistently made available to the set-top box, using up valuable bandwidth even if your TV is off. In early trials, Time Warner Cable announced the bandwidth savings "exceeded 50%," so they've been aggressively deploying the technology.

Third-party DVR competitors such as TiVO were worried the two-way technology would render one-way Cablecards useless. The National Cable & Telecommunications Association (NCTA) announced last year they'd work with TiVO to develop an external adapter by Q2 '08. While they wait, some Time Warner Cable CableCARD users have been forced to use incumbent set tops if they still want to watch video in SDV markets.

Good news for those users: Light Reading notes that CableLabs has awarded qualification to tuning adapters from Cisco and Motorola that will allow CableCARD users to view programming in switched digital video (SDV) markets. Now it's just a matter of the cable operators getting them into customer hands, something there's not huge incentive for, given they want users paying to use their own set top gear. For their part, Cox says they'll be handing out the adapters for free, while Time Warner Cable says it's "too early" to discuss specifics.

TWC best watch their step

Or they risk the wrath of FCC do-gooders pressured by Sen. in an election cycle.

Meanwhile everything I read was about the focus on TiVos but I'm wondering about other cablecard tuners. The other day there was a Sony Blu-Ray Vista HTPC with CableCard built in for $999 in the Hot Deals forum. I wonder if these USB SDV adapters will work with these Cablelabs approved Vista machines that include Cablecard.

That is a big question I have. I just implemented an HDHomerun - I'd hate to have it killed by SDV.

Why should TWC watch their step? they're not doing anything they shouldnt be doing with SDV.

Re: TWC best watch their step

If they start charging high fees for SDV add-on boxes it could be seen as anti-competitive by the FCC who is pushing cablecards.

... for the very small, and I do mean VERY small group of people that SDV affects, I don't see the issue. There's not "step" that needs to be watched, etc. There are millions and millions of cable TV customers out there and the number of those that have the older Tivo and other devices is a very small amount.

Can't even see that these devices will be out there for very long as it is as new equipment will be made to handle SDV.

Personally, I think the end user should PURCHASE the adapters themselves. NOTHING, not a dime, should be subsidized to the end user consumer...

This is hardly anti-competitive.. it's called evolution.

Tivo info on switched tuning adapters

»www.tivo.com/setupandsupport/how···ils.html

Explains what Tivo is doing and page has a Q&A on tuning adapters for switched digital video.

Note that these tuning adapters for SDV do NOT support VOD from the cable companies.

Re: Tivo info on switched tuning adapters

Ok, I was interested in Tivo perhaps if the SDV adapter would enable VOD support, but Tivo just lost my business. No VOD, No Tivo. I could of potentially purchased a Tivo HD and used this adapter, but I guess I'll stick with the subpar Motorola DVR. Might be slow, but at least it gets HD-VOD.

Technically the SDV Adapter should be able to support VOD, just a software frontend that reads and displays the titles and talks to the VOD server is all that's needed. VOD is technically switched across 4 QAM's on my Comcast system.

HD compression?

Does this mean Comcast can now un-compress HD signals such that subscribers who want to watch shows in full HD quality can actually do that?

From what I understand, this is optimization of the last mile (edge router to STB) bandwidth. So wouldn't it be possible for the user to control what exact channels consume that bandwidth?

It could. But it will most likely mean MORE HD channels, which is what users are clamoring for. They are not clamoring for less compression.

Re: HD compression?

Sure - but how does this really work? As an end user, am I told how many HD channels I can have in the last mile versus that plus X regular channels?

What I mean is, they add more HD channels, hold them at the edge router and I as a user control how many full signal,uncompressed channels stay active in the last mile pipe?

Think of it like DSL - your last mile is capped at X Mbps whereas before the CO, there's a OC-X pipe but content trickles down the X mbps capped pipe to your PC.

End users will have no say in how their channels are delivered to the edge router. It will be a statistical algorithm based on how many users are on a node and how many different channels they are watching spread over the available bandwidth.

The problems that arise will happen when the multiple viewers on a node watch more unique channels than the bandwidth allocated to the node allows. Sort of like what happens today when many users try to use VOD at the same time and run out of channel space allocated to VOD at the node. They get an error message.

If SDV is not configured correctly or some unique combination of users on a node all requesting different channels occurs, you could end up trying to watch a channel and get refused and end up just getting an error msg.

Re: HD compression?

The TTL question still remains. There needs to be a concise policy on which takes precedent (re:bandwidth), vod or hd.
The market would come into play of course but I could see a clear cut in service when it comes to VOD and HD. Ex: are you going to have antiquated movies removed and offer less than popular HD channels because more people are demanding a certain video or want a specific channel?

I don't think there's a real chance of that if they actually deploy all of the channels as switched video. I don't think they have more than 200 households on a single node that will watch 200 exactly different channels at the same time

But with multiple users and multiple TVs & STBs in many households, it starts to become possible.

Scientific Atlanta?

I see Motorola and Cisco are the two vendors providing these devices so far. Presumably the Cisco adapter will be deployed in Scientific Atlanta equipment areas?

bandwidth savings "exceeded 50%"

In early trials, Time Warner Cable announced the bandwidth savings "exceeded 50%," so they've been aggressively deploying the technology.
This suggests that since the bandwidth savings directly correlates with TV viewing habits, that more than 50% of the content that's being broadcast at any time of day (that you're paying for) is not being viewed. So, since this technology definitely results in a bandwidth savings and potentially lower power needed to distribute the content, will the consumer see a benefit? Lower costs? Unlikely. A greater ability for cable companies to track your viewing habits, absolutely! Lower consumer prices because they can more accurately target their viewing audience's viewing habits? Unlikely.

Re: bandwidth savings "exceeded 50%"

Actually, you'll probably see price increases because the cablecos will need to purchase additional content that they can now distribute with their unused spectrum.

Free? hardly. nothing dealing with tivo will be free. as a tivo user you should know that by now. a nickle here a dime there...

The adapter will not be coming from the folks at TiVo, it will have to be deployed to you by your FCO. Some are opting to offer them for free and others I'm sure will charge for them.

this defeats the whole purpose

I got a CableCARD tv to get away from boxes....so now my solution to "fix" cablecard is to get an adapter box.

this is so fucking retarded.

Re: this defeats the whole purpose

Yes, but this box is easily hide able behind your Cablecard device. It does not have a remote, or any need to be otherwise visible, stash it behind your TiVO, or back in the bundle of wires behind your entertainment center, and you are good to go.

It is also worth noting that these tuning resolvers will NOT work on a normal CableCard set, only on the TiVO Series3/HD (so far).

Re: this defeats the whole purpose

I dunno. Using a basic wallwart with wire nearly the size of human hair leads me to believe it's not using much power at all let alone 'more'.

If it uses 12V and not much amperage, why not tie it into the power supply of your tivo? Or get a real short extension and power plug splitter and use a single socket.

As much as you may want a 'clean' setup, NOTHING is going to use 0 power.

If it wasn't for Tivo doing everything in their power to avoid doing things 'right', they could have VERY easily put 2-way tuners in their boxes and implemented a resolver in software and avoid all this in the first place.

What's the big deal about boxes? My Directv HD DVR looks pretty slick in Glossy Piano Black, and I'm used to a box I guess, we've had one since cable first came to our West Covina home in SoCal back in 1984.

So the SDV allegedly frees up bandwith. Is there any quantifiable evidence of this theory? Why should I want one. Where is the Features-Advantages-Benefits of this device so I can make an intelligent decision as to whether it's even worth my time.

You'll want one when/if your cableco begins using SDV. Otherwise, use your cableco's STB or choose a different mechanism to receive TV.

That's not how it works- they can't just deploy SDV to one user, they have to deploy it to the entire system at once because of how the cable system works.

And of course SDV frees up bandwidth- let's say you have 20 SD channels, on a 5-1 compression that uses 4 channels. But if only ten of those channels are being watched at once, you only need to dedicate two channels on the coax, and have two open for other uses (more channels, more HD, DOCSIS 3 channel-bonding, etc.)

That is if the cable co do SDV the right way by useing it for low use channels and keeping the high use ones on all the time.

SdV is used heavly in San Antonio

The way the SDV works in San Antonio they cannibalized all the PPV, the west cost channels for HBO, Showtime, TMC, Max and Starz, and the sports package channels ie. NBA league pass, NHL center ice, ect. and put them on SDV. All new channels added after this are SDV now. So mainly all the newer HD channels. The only HD channels that are real channels are the local stations, TNT, Discovery HD theater. ESPN, Mojo, HD Net/Movies, Universal HD, HBO East, Showtime East. All other HD channels are SDV. As far as I can see they really did not eat any heavy use channels.

why not put all of HBO, Showtime, TMC, Max and Starz on SDV there must be some area with very low use of them.
