Figure 9-14 HDMI implementation
The description of the lines is as follows:
• TMDS (Time Minimized Differential Signal): the actual
HDMI signal
• DDC (Digital Data Channel): the bus used by the source to
read EDID data in the EEPROM and HDCP
authentification
• HPD_RST_A (Hotplug Detect Reset signal): used to pull-
down the HPD signal level at the connector when switching
in/out of HDMI mode; the duration of the pulse is around
500-550 ms
• DDC_RST_A has the same behaviour as the HPD_RST_A
signal. It is used to pull-down the I
some problems with certain video graphic cards
• HDMI_CEC_A is the Consumer Electronic Control remote
control signal bus.
It should be noted that in this chassis the HDCP-key is
embedded in the main processor (no need for a separate
Service-SSB).

High-bandwidth Digital Content
Protection; A "key" encoded into the
HDMI/DVI signal that prevents video
data piracy. If a source is HDCP coded
and connected via HDMI/DVI without
the proper HDCP decoding, the
picture is put into a "snow vision"
mode or changed to a low resolution.
For normal content distribution, the
source and the display device must be
enabled for HDCP "software key"
decoding
