EDID Minder
The DTP2 R 212 uses EDID Minder, which ensures that a source device connected to the
receiver input continuously sees the EDID of a sink device, even if the sink is not physically
connected. By default, the EDID is set to 1080p @ 60 Hz with 2‑channel audio. EDID can
be configured with PCS (see the DTP2 R 212 PCS Help File).
EDID Memory Retention
The assigned EDID is stored to an EEPROM, which is located at the HDMI input. The stored
EDID is retained until a reset is initiated.
Hot Plug Detect (HPD)
HPD remains high on all inputs while the unit is powered on. The HPD drops low only while
EDID is updated.
HDCP
Input
The HDMI input negotiates and authenticates HDCP with the source device if the source
requires HDCP encryption. The authentication process is repeated whenever the stored
EDID is changed or updated, which is indicated by pulling HPD low.
HDCP support can be disabled only for the HDMI input using the SIS command
Authorized Device (for HDMI input only)
PCS Help File).
Output
The output is individually pre‑authenticated and encrypted, in accordance with the
configured HDCP output mode using SIS commands (see
page 43) or PCS (see the DTP2 R 212 PCS Help File).
If an output requires encryption but the connected sink device cannot be authenticated, that
output displays a green screen.
HDCP output modes
Follow input — Output is always authenticated but only encrypted when required by
•
input. HDMI authentication is continuous. DVI authentication occurs for a maximum of
10 seconds, then fails. This is the default mode.
•
Always encrypt output — Output is always authenticated and encrypted. HDMI
authentication is continuous. DVI authentication occurs for a maximum of 10 seconds,
then fails.
Audio Configuration
Analog Audio Mute
The analog audio output can be muted via SIS commands (see
or PCS (see the DTP2 R 212 PCS Help File).
Output Audio Configuration
Embedded audio can be enabled or disabled on the HDMI output via SIS commands (see
Output Audio Configuration
on page 43 or PCS (see the DTP2 R 212
on page 45) or PCS (see the DTP2 R 212 PCS Help File).
