	Digital Transmission Content Protection (DTCP) - Intel in Standards
		Protect the rights of content providers and content owners, recognizing their right to be compensated for their intellectual property.
		Content owners were rightfully concerned that the new unprotected digital outputs would enable pirates to hijack a digital data stream and create an unlimited number of perfect copies.
		Digital terrestrial broadcast is transmitted "in the clear" (unencrypted) and thus can't be protected at the source.

		Digital cameras, personal video recorders, MP3 audio players, HDTV displays, digital set-top boxes, and new generations of mobile devices and media center PCs are just a few of the products generating buzz in the world of consumer electronics (CE).
		Content protected by known (and future) DRM schemes should be brought together into a secure location where it may be transcrypted from the original DRM into a common, single copy protection mechanism that preserves the digital rights information of the original DRM.
		Additionally, premium content protected by a future DRM technology may not be render-able on devices already in the field unless they included a mechanism for in-field updates.

	Smart TV & Sound -Guide to Digital Home Entertainment
		In the digital world, television signals are perfect, you either have the signal or you don't and built-in error correction takes care of the rest.
		Watermarking is a technology that allows information to be embedded in content in a way that is intended to be invisible (and inaudible) to the end-user of that content and robust against the information being removed or altered.
		DTCP is a standard specifically developed by DTLA (Digital Transmission License Administration), according to Reed Hinkel, vice president of business development for Oregan Networks Americas (http://www.oregan.net).

		As the whole content distribution chain went digital, Hollywood was concerned that there would be no legal or technical recourse against devices or applications that were easily hacked to allow perfect copies of digital content.
		DTCP — Digital Transmission Content Protection is a link protection for compressed digital transmission over IP as well as MOST, Bluetooth and 1394.
		For example, if the content is marked as "copy no more", then the application could play the content locally, such as via a speaker, but must not pass it out on certain digital outputs.

	Sony, Warner license anti-piracy standard - ZDNet UK News (Site not responding. Last check: 2007-10-16)
		DTCP is a standard that prevents people from intercepting and re-broadcasting movies delivered digitally to home viewers.
		When the program "is received in your home on a digital set-top or cable box, it then enters the DTCP domain," said Michael Ayers, president of the Digital Transmission Licensing Administrator, an organisation created by electronics manufacturers Sony, Hitachi, Intel, Matsushita and Toshiba.
		While the DTCP is a step toward protecting digital programs, there are still gaps in the overall picture.

	Global Music Resource - Digital Rights Management and Content Protection (Site not responding. Last check: 2007-10-16)
		With a watermark embedded in the digital audio file the copyright holder can certify the copy is authentic (fraud prevention) and the owner of the copy is authorized to have it in their possession (anit-pirating or license compliant).
		Various content providers are joining together to use this platform to provide digital commerce services parallel with the offering of digital audio to the public.
		This concept envisions that digital files (not only music) will be encoded, and depending upon what decoding application you may have purchased for your computer and what "rights" that application entitles you to, you will only be able to listen, download, purchase or reproduce the file, or a combination of the several rights.

	Bringing content protection to the digital home (Site not responding. Last check: 2007-10-16)
		DTCP defines a secure protocol for protecting audio/video entertainment content from illegal copying, intercepting, and tampering as it moves across digital interfaces such as Universal Serial Bus (USB*), and IP-based home networks.
		Intel’s goals for a protected digital environment for the home network face new challenges as content protection moves from wired to wireless.
		Intel sees this technology as crucial to its vision of the digital home where DTCP-IP makes a perfect common denominator for protecting content as it is exchanged from one device to another, such as from a desktop PC to a digital video recorder (DVR) connected to a TV.

		DTCP was developed by the so-called "5C" group of PC and consumer heavy-hitters: Hitachi, Intel, Matsushita, Sony, and Toshiba.
		Hollywood wants the 5Cs to include such conditions as "no Internet retransmission" in the DTCP specifications so that "it would be much easier, on a long-term [basis], to manage the situation where everything can be connected and retransmitted digitally, when the high-speed connection becomes available," said a movie industry executive.
		The 5Cs insist the DTCP spec was primarily designed to protect "just the wire" connecting a set-top and a digital TV or a PC.

	Content protection plan targets wireless home networks
		But when DTCP was developed by 5C — a group comprising Intel Corp., Hitachi Ltd., Sony Corp., Toshiba Corp. and Matsushita Electric Industrial Co. — "the notion for the wireless-connected home was not there," said Husson.
		Other approaches to content protection don't necessarily ignore wireless transmission, but Philips is actively focusing on that transmission approach, he added.
		And while DTCP requires re-encryption at every digital device border, SmartRight keeps content encrypted from the time it reaches a digital set-top at home until it is rendered, he said.

	DVD FAQ
		When protected content is recorded onto the disc, it can be encrypted with a 56-bit C2 (Cryptomeria) cipher derived from the media ID. During playback, the ID is read from the BCA and used to generate a key to decrypt the contents of the disc.
		Digital devices that do nothing more than reproduce audio and video will be able to receive all data (as long as they can authenticate that they are playback-only devices).
		Digital recording devices are only able to receive data that is marked as copyable, and they must change the flag to "don't copy" or "no more copies" if the source is marked "copy once." DCPSes are designed for the next generation of digital TVs, digital receivers, and digital video recorders.

		If a content owner doesn't want to risk degrading content with a watermark, CPSA also allows CMI to be packaged as a discrete piece of data that accompanies, but is not embedded into, the content.
		The lock that enforces such a system in the digital domain is encryption, which scrambles content until it is decrypted by a compliant device, according to the rules specified by the CMI.
		In the case of DVD content protected by CPPM or CPRM, encryption is performed by the C2 (Cryptomeria Cipher) function, a mathematical operation designed specifically to protect multimedia content.
