Time Warner Austin has continued to switch the digital channels to Switched digital. everyday I lost another channel or two.. by the end of the year I don’t think i will get any digital channels except the local over the air ones..

I would not recommend that anyone buy a TivoHD until the cable companies are ready for it.. I love Tivo, but not getting the channels you pay for is unacceptable.

The Cable boxes that are now required can do SDV and other 2way stuff even with a series 1 cable card because the box is the thing taking care of the 2way communication. The cable cards are only used to authorize it on the cable companies network.

Why can’t TiVo just develop a S3 which is capable of doing 2 way communication? Is there something which prevents TiVo from doing this?

Jeremy you are totally wrong.

Unfortunately, since the CableCard 2.0 standard (which certifies the device, not the card) was certified prior to the July 1, 2007 deadline, cable companies’ SDV WILL be compliant with this standard and thus the law. Needless to say, your Cablecard 1.0 Tivo Series 3 won’t be. Sorry to be the bearer of bad news.

Doug,
That Multi-channel news article does a great job of explaining why all channels won’t be SDV and of course you’r right it’s not fair to say “all new” either. The “all new” explanation only works if they are less popular, which I’d assume they are at first.

There is no way “all digital channels” will be SDV or even all new channels. Less popular channels will be SDV.

SDV only saves you bandwidth if the channel isn’t being watched, if it is, then it uses the same bandwidth as if it was a broadcast digital channel. SDV is not the same as packet switched (IPTV), it still uses a channel like a phone call uses a line.

Think of it like a phone system where there is a wire to everyone’s house, but not enough “circuits” for everyone to use the phone at the same time. But if everyone wanted to join the same party line, they could all use one circuit for that.

Look at the illustration above, but realize there are many more houses than 10 on distribution hub, I’d guess there are more than a 100.

Lets imagine there were 300 homes on a hub, then if all digital channels were SDV and everyone wanted to watch something different, they would need the same complicity as if all 300 channels were sent 100% of the time.

Making a statement like “all NEW channels will be SDV” may not be correct as it doesn’t seem to jive with this article:

http://www.multichannel.com/article/CA6454447.html

It looks like they can’t put everything on SDV as the system couldn’t handle it.

It’s clearly not a good situation for TiVo 3 owners though.

Given the FCC is now requiring cable company boxes to use cable cards in their own boxes, it seems SDV will either need to be delayed or some serious progress made with cablecard 2.

SDV is no doubt a concern for every Series3 owner, but there is still hope that the FCC will step in and force CableLabs to come with a work around. Honestly my biggest fear is that they will add a channel via SDV that I actually want to watch before there is a solution.

Based on your knowledge, do you think that it is likely that TWC would/could switch over all digital content in my area to SDV?
