KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
4
•
Supports standard, enhanced, high-definition video, and multi-channel digital
audio
1
•
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
on a single cable
•
Benefits consumers by providing superior, uncompressed digital video
quality via a single cable
2
•
Is backward-compatible with DVI (Digital Visual Interface)
, and user-friendly connector
•
Supports two-way communication between the video source (such as a DVD
player) and the digital television, enabling new functionality such as
automatic configuration and one-button play
HDMI has the capacity to support:
•
Existing high-definition video formats (720p, 1080i and 1080p @60), as well
as standard definition formats such as NTSC or PAL
3.2 About HDCP
The High-Bandwidth Digital Content Protection (HDCP) standard (developed by
Intel), protects digital video and audio signals transmitted over DVI or DVI
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.
3.3 Defining EDID
The Extended Display Identification Data (EDID
13F
3
) is a data-structure provided by a
display to describe its capabilities to a graphics card (that is connected to the
display’s source). The EDID enables the
PT-101H4
to “know” what kind of monitor
is connected to the output. The EDID includes the manufacturer’s name, product
type, timing data supported by the display, display size, luminance data and (for
digital displays only) the pixel mapping data.
1 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to support
Dolby 5.1 audio and high-resolution audio formats
2 HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-
effective manner
3 Defined by a standard published by the Video Electronics Standards Association (VESA)
