Cinavia watermarking

This method of DRM (Copy Protection) has started turning up on BD and other theatrical digital recordings and is currently (starting in 2012) detected by Sony PS3 and maybe some other Blu-Ray players.

It is an additional protection method to AACS and is also designed to protect media that is captured by video cameras, CAM or TS recordings. The detection of the "watermark" in the recording by the playback device will suspend the playback of the media after a period of time. It is supposed to be able to determine whether the copy was made from a camera or a direct copy of the BD, i.e. a "rip".

get_iplayer

get_iplayer.exe is a separate downloading program (from the BBC iPlayer download facility) and can be used to download  BBC TV and Radio, DRM free and not time limited.

Since Po-Ru`s ipdl.exe broke late in 2010 I have been using a variation of Phil Lewis's get_iplayer.exe for BBC TV and radio (a fork by David Woodhouse, infradead.org) .

It was thought that ipdl broke due to  the changes that the BBC instituted to make iPlayer compatible with Apple's iOS4, a full account can be found on Po-Ru`s blog.

I have found a few "work-arounds" as even get_iplayer has been broken over this time period. The version that I have working uses a different version of the FLVstreamer module.

The get_iplayer package is an extremely complex and competent suite of Perl scripting using the RTMP library.

Other pages relating to get_iplayer and the RTMP library:

• RTMP and RTMPdump - Freeware console application for downloading RTMP and RTMPE streams
• get_iplayer development on tempusfugit.ca
• Downloading 4OD and Channel 5 using RTMPDump. 

I use get_iplayer to build my archive of BBC programming. get_iplayer is a very competent Perl script that has many options. get_iplayer can be used as a command line program and there is a GUI PVR version of get_iplayer, that runs get_iplayer in a scheduled mode.

DRM and circumvention

The circumvention of DRM systems. A wide range of issues from the backup of digital media to the access of material from outside specific geographic locations.

• The use DVD43 in a 64 bit environment. - Copying DVDs and Blu-Ray
• Vidalia Tor and Geo-location restrictions
• The main page for Vidalia Tor on The Technology Muse - GeoIP circumvention in general
• Will Vidalia Block Copyright enforcement companies?

DRM - Digital Rights management (Restriction) is the general term given to the techniques used to restrict the copying and access to digital media in situations where the rights holder does not want you to.

libdehdcp

Now that the HDCP key**** is loose will the ghost of Dr. Peter Gutmann emerge from the shadows?

Halloween is coming up after all.

Is there really a need for an AACS defeating version of good old libdvdcss? It would seem that many are content with the DVD quality and the step to BD is not worth the hassle of wrestling with HDCP keys and the like.

Oh, for those that may be lost in the acronym soup:
AACS - Advanced Access Content System (for High-Definition Video discs)
HDCP - High-Bandwidth Digital Content Protection
BD - BluRay Disc (of course - but it still needs to be said)

 **** in fact the usage of HDCP is not really relevant as the discussion is more likely to be about libaacs.dll

Copy Protection and methods used to protect Copyright

How to overcome DRM and backup the things that you own. The methods used by Copyright owners to protect their intellectual property.

• DRM and its circumvention - a general discussion on the methods that I have discovered
• ACTA and other International agreements related to copyright protection
• The DMCA - Digital Millenium Copyright Act
• PIPA and SOPA
• The issue of IP rights - 2012
• Bill C-11 - An Act to amend the Copyright Act (Canada)
• Anti Peer-top-peer organizations
• The use of DVD43 on a 64 bit computer

AACS - Advanced Access Content System

Advanced Access Content System (for High-Definition Video discs)

I have full details on how to overcome the AACS encryption system, if you want to find out more about this you need to search this blog.

Torrent and Bandwidth Hogs

Why would an ISP offer accounts with 95G of bandwidth per month if they didn't have the network infrastructure to support 3 to 4GBytes of traffic per day?

To say that ISPs would rather the users of torrents go away and that this is detrimental to the other users of the network does not make sense.

Copyright infringement and DRM is another issue and will be pursued.

anyDVD HD by SlySoft

This is an alternative method used by to decrypt DVDs and BD - other methods include:

• DVDs are copied using DVD43 in an XP-Mode Virtual Machine
• DVD43 in a VirtualBox VM (you don't need a computer with Windows 7 or XP-Mode).

• anyDVD43 a "cracked" copy of anyDVD HD
• Slysoft website
• Running DVD43 on a 64 bit Windows computer on the Technology Muse. 

As you can see, anyDVD is not cheap - you can buy a 1 year license or subscribe to lifetime updates:
