CableCARD to Get Relaxed DRM

It has always been hard to stomach the DRM variations that CableLabs has set up between OCURs and UDCP devices like TiVo’s.  TiVo gets the ability to have non-DRM recordings if the content provider hasn’t flagged the broadcast at all whereas Media Center with CableCARD has to protect everything no matter what.  This discrepancy might is ready to change.

CableLabs recently unwrapped an update to the OCUR specs in which they appeared to have removed the “Requirement to Protect Output of Content with No Protection Flags.”

Hard to say whether you will need the Windows Media Center TV Pack to take full advantage, but based on what S1Digital is planning to ship it would appear that at least at first the TV Pack will be required.  There will also have to be a Digital Cable Tuner update that would most likely allow shows not marked as copy protected to skip the WMDRM process within the tuner.

Is S1Digital not bound by an NDA ;)

Hmm...  I guess at this point I'll stick with my speculation that TV Pack is actually just an update to the Digital Cable (CableCard) version of Vista.

If (BIG "if") this is he case, I wonder if those of us who have already shelled out the extra cash for CableCard VMC over the last year will get in on the TV Pack goodness..

There is no such thing as the "Digital Cable version of Vista."  That's just a retail copy of Vista with a second product key that is input into Media Center (and the BIOS).

Hmm... and now I know... and knowing is half the battle...  Thanks.  

I'll quit spouting off about it then, and wait like everyone else.  :-)

Chris,

Can you link to the specification that changed? I look around CableLabs' site and wasn't able to figure out which one changed. I assume it is this one, but if so what page?

It is the table on page 40.

That is what I was looking at, but wasn't able to make sense of it.

Basically, if no flags are on the broadcast (all of those 0's), then no DRM needed.

great job with this site, Chris.

I'd like to see an article devoted to Cablecard and laptops - which ones are available that support cableCard. Right now I'm using a standard Vista laptop with HDHomeRun and Comcast, but would like to figure out how to get all the HD didgital channels through VMC that Comcast Offers.  

BTW - using firewire and fireSTB driver fouled up regular recording in VMC really badly, such that Service Pack 1 had to be installed which thankfully straightened it out. firewire recording and the Comcast STB seems not ready for prime time.  But maybe CableCard will get me where I want to go?

thanks again.

Your link to "Windows Media Center TV Pack" in the post is not functioning.

This actually might a be a flying pig moment.  When has DRM actually been lessened by a company?

hd: I might be able to do a CableCARD with laptop article at some point, but really only Sony has one that I know they are shipping.  Toshiba has one certified (I think), but I don't know if it is still shipping.  Having to connect a huge external tuner to a laptop isn't a big market opportunity.

DWAnderson: Thanks, fixed.

Jeffrey: This might be a first.  :)

Is now a good time or a bad time to buy a Cable Card-equipped XPS 420? I'd like to pull the trigger but with the Media Center TV update and now with the tuner firmware update on the way...?...should I wait?

# re: CableCARD to Get Relaxed DRM

Thanks for the info Chris. It seems to me that with lots of companies promoting the "desktop replacement," and also selling laptops with tuners (my Toshiba included one, and HP promotes a laptop with Expresscard), that including CableCard with verification would be the next logical step. I guess not.

thanks!
