3 Overview
The high quality
FC-49
DVI / Audio to HDMI Converter
accepts a DVI input
and an audio input (analog, optical or digital), and combines both these A/V
signals into an HDMI output.
In particular, the
FC-49
:
Adds HDMI output capability to your DVI source so that, for example,
an HDMI television can be used with your DVI source

3.1 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.
3.2 Defining EDID
The Extended Display Identification Data (EDID
3
) is a data-structure,
provided by a display, to describe its capabilities to an HDMI source. The
EDID enables the
FC-49
to “know” what kind of display is connected to the
output. The EDID includes the manufacturer’s name, the product type, the
timing data supported by the display, the display size, luminance data and (for
digital displays only) the pixel mapping data.
1 For example, the DVI source can also be the DVI graphics output of a PC as well as its audio signal
2 If an analog signal is not detected, the digital input (S/PDIF) is selected. If both analog and digital signals are not detected,
the machine selects the optical input (TOSLink)
