Talk:Content Protection for Recordable Media

There was an article deleted about -RW2 blank media, as it was thought to be a hoax, but JVC DVD-RW ver.1.2 media works with CPRM and has a "RW2" logo. Jnhrtmn (talk) 21:07, 25 March 2010 (UTC) jH

I have a Toshiba HDTV. I recently purchased a Toshiba progresive scan DVD player. My son played a dvd on our system and the tv shut down. I think he had a boot copy of some movie. Can the DVD player send a code to the TV and shut it down? I can nolonger get my tv to come on.

That kind of vandalism wouldn't be practical for several reasons. I think something is wrong with your TV.

Anyway..

"Only special CPRM-enabled media formats, which do not yet seem to have achieved market visibility, will impose copying restrictions."

According to its manual, the Panasonic DMR-ES20 DVD video recorder requires a CPRM compatible disk (DVD-RAM) to record digital broadcasts that impose a "one time only recording" fair use restriction. If this is similar to other DVD recorders then it would seem like CPRM-enabled media formats have achieved market visibility. -DWM


 * This is true of the Panasonic DMR-ES35V too.  I wound up on this page after looking it up when I noticed it in the manual. ~IMP

Can someone explain what this is? A duplicate key? A similar key? Thx, Daniel.Cardenas 18:38, 25 June 2007 (UTC)

Usage of CPRM by the end user
I think the article does not clarify of what use CPRM may be to the end user, e.g. of a digital camera. From reading the article I cannot get the point how the content protection should work. Is it simply a kind of encryption such as an encrypted disk image, which requires a key or password to open it? One of the moste widely spread uses of SD cards is digital photography, but I have never seen a digicam which asks the user for a password to access or encrypt photos. Or did I completely misunderstand the way CPRM works?

Anyway, large passages in the article seem to be copy & pasted from (which, however, does not answer the questions above either).--SiriusB 16:04, 23 August 2007 (UTC)

You seem to be under the mistaken impression that DRM is equitable: consumers can't produce protected content. You have to pay a licensing fee for that. From "The Digital Paradox" section: "The downside of digital is consumers’ ability to make near-perfect copies of music, videos, and games and distribute them en masse, without paying for them. Consumers don’t want to be told how they can use their content or playback devices, nor do they want to bother with protection technology that forces them to comply with cumbersome procedures or prohibitions."

Memory Card Reader need to support CPRM?
Just would like to know if I need a CPRM supported Memory Card Reader to store the media into SD card? —Preceding unsigned comment added by 210.80.72.178 (talk) 07:28, 24 February 2010 (UTC)

Exists?
Does this exist? I've never encountered it, and I've ton of devices that I transfer all kinds of data to and fro. Apple8800 (talk) 04:32, 2 February 2011 (UTC)
