Cables & Connections
HDMI Jack and Cable
The DIRECTV Plus HD DVR incorporates HDMI™ [or High-Definition Multimedia Interface] tech-
nology. HDMI offers a high-quality connection that combines the video and audio signal into a single
cable.
The HDMI jack uses HDCP content protection to allow you to view HD programming that has been
encoded using the HDCP protection system. For the best access to HD programming at the highest avail-
able resolution, connect this to an HDTV that supports HDCP technology.
DVI (Digital Visual Interface) is an older digital connection standard that has been replaced by HDMI
and is compatible with HDMI. DVI carries video only. You can also use an HDMI to DVI converter (not
included), which also carries video only, so must be used with audio cables to receive the audio signal.

Component Video Output (YPbPr)
The component connector provides high-quality video for your HDTV system. Component video is also
referred to as “YPbPr.” It uses three separate cables—with connectors colored green, red and blue—one for
each component of the HD video signal. A separate audio connection is also required, using either Digital
Audio Optical cable or the audio portion of an A/V cable.

Digital Audio Outputs (Optical Jack and Cable)
The Digital Audio Optical cable provides the best quality audio. The jack and cable use light to send digi-
tal audio data to A/V receivers equipped to receive and interpret it. The jack and cable (cable not includ-
ed) must be aligned before plugging in, and may be covered by protective caps, which must be removed
before making connections. Use caution when handling optical cables: They are delicate!
