Hdcp Copy Protection

With most developments in life that are meant to make our life easier, there always seems to be an accompanying down side; the rapid advancements and availability in digital content the world over is no exception to this rule, and is a perfect example of this dilemma.

The upside is that the problems we face with the ever increasing availability of digital products, also motivates the manufacturers of these devices to improve them to meet the demands and concerns of both the consumer and those who publish the popular content used via these digital devices.

Copy protection of content held on digital media is of major concern and many years and millions of dollars have gone into the research and development of an effective method of protecting valuable digital content.

This is where High-Bandwidth Digital Content Protection comes into the picture.

* What is HDCP?
High-Bandwidth Digital Content Protection is a copy protection system developed by Intel and licensed by Digital Content Protection LLC, to prevent the copying of digital information; a technology which uses an authentication and key exchange process prior to rendering the digital content for its intended purpose.

Typical devices compatible with HDCP are DVD players and HDTV equipment; it is a standard that is gaining rapid acceptance by many manufacturers of relevant digital equipment. Therefore, it is highly recommended that you ensure whatever HDTV or DVD equipment you purchase is compatible with HDCP.

* Reasons to Purchase HDCP Equipment
Besides the obvious copy protection technology, the other main reason to start purchasing HDCP compatible equipment is that manufacturers are gradually phasing out the older analog based technologies.

Although the new generation of products like HD-DVD and Blu-Ray devices will still support the analog output resolution, the resolution of this type of output will be limited to 720p, 1080i and 1080p. This support will be provided via the digital (DVI or HDMI) connections that make use of HDCP encryption.

* HDCP Compliant PC Monitors
HDCP is not yet a standard for use in PC monitors, which means that although PC monitors are HDTV capable, they are severely limited when it comes to HDCP content. You need to make sure that your monitor is HDCP compatible if you wish to make use of it with HDCP media.

* Basic HDCP Key Exchange Process
The HDCP media and rendering device swap digital keys, which is basically a way of ensuring that each party in the key exchange is actually authenticated to manage the digital content. If either party is unable to issue the required digital key then the content will not be rendered to the display.
