About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard developed by
Intel protects digital video and audio signals transmitted over DVI or HDMI
connections between two HDCP-enabled devices to eliminate the reproduction of
copyrighted material. To protect copyright holders (such as movie studios) from
having their programs copied and shared, the HDCP standard provides for the
secure and encrypted transmission of digital signals.

About DisplayPort–General Description
DisplayPort (DP) is a digital display interface standard for the PC industry. It
delivers the highest resolutions and sound quality. In addition, DisplayPort:
•
Provides a simple interface between a PC and a display, projector or TV
•
Supports 1 to 4 data pairs ("lanes") at a transfer rate of either 1.6Gbps or
2.7Gbps (device dependent)
•
Has a maximum length of 15m (49ft) for video transmission at a resolution of
1080p/60Hz and 3m (9.8ft) for full bandwidth transmission
•
Video specs include a video path that supports 6 to 16 bits per color
channel, a maximum resolution of 2560x1600 pixels and a total maximum
bandwidth of 10.8Gbps over four lanes
•
Is backward-compatible with HDMI, DVI (Digital Visual Interface) and VGA,
via an appropriate adapter
•
Version 1.1 supports HDCP
•
Supports two-way communication over its auxiliary channel between the
video source (for example, a PC) and the digital display, enabling new
functionality such as automatic configuration and one-button play
•
Replaces the interface needed between the PC and an external display, as
well as the low voltage differential signaling (LVDS) interface in notebook
computers, monitors, to connect to LCD panels
