What is HDCP?
High-Bandwidth Digital Content Protection (HDCP) is a copy protection technology designed to prevent transmission of illegal High Definition content. You will need an HDCP capable monitor/video card in order to watch 1980x1080 high-definition HD-DVD/Blu-ray media.

What are the requirements for watching Hi-Definition content?

  • "HDCP Enabled" graphics card
  • Monitor supporting HDCP
  • Blu-ray/HD-DVD drive and media
  • Software Player that supports HDCP content
  • DVI/HDMI monitor connection

As you read about HD DVD and Blu-ray movie playback on PCs, you'll come across many acronyms describing new technologies and standards. We've provided a glossary of some of the most common terms.

The Advanced Access Content System (AACS) is a copy protection standard use with HD DVD and Blu-ray discs delivering movie content.

Blu-ray Disc
Blu-ray is a new high-definition video disc standard that offers up to six times the visual detail of traditional DVDs. Blu-ray discs can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc. This extra capacity combined with the use of advanced video and audio codecs offers consumers an amazing HD experience.

Digital Visual Interface (DVI) is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors.

H.264, also known as MPEG-4 AVC (Advanced Video Coding), is a video compression standard that offers significantly greater compression than its predecessors. It is one of the 3 CODECs that can be used by the Hollywood studios when authoring Blu-ray and HD DVD movies.

High-Bandwidth Digital Content Protection (HDCP) is a form of copy protection technology designed to prevent transmission of non-encrypted high-definition content as it travels across DVI or HDMI digital connections.

HD DVD is a new high definition video disc standard that delivers up to six times the image quality of standard DVD movies. HD DVD promises a major advancement over video discs in the same way that HDTVs deliver superior image detail over standard TV.

High Definition Multimedia Interface (HDMI) is a new interface standard for consumer electronics devices that combines HDCP-protected digital video and audio into a single, consumer-friendly connector.

Image constraint token (ICT) is a software-based flag within Advanced Access Copy System (AACS) copy protection that would automatically reduce the quality of the image produced by a high-definition video disc player to 540 lines of vertical resolution, when the player is connected to an analog display.

VC-1 is a video codec based on Windows Media Video Version 9. Both HD DVD and Blu-ray Disc have adopted VC-1 as a codec, meaning all video playback devices will be capable of decoding and playing video-content compressed using VC-1. VC-1 minimizes the complexity of decoding high-definition content through improved intermediate stage processing and more robust transforms. As a result, VC-1 decodes HD video twice as fast as H.264, while offering two to three times better compression than MPEG-2.
