HDCP status: inputs and outputs
Through a series of SIS commands (see
) or using PCS
(see
Product Configuration Software
starting on page 61) the DVS 605 has the ability
to report HDCP status of the HDMI input signals as well as connected HDMI sink devices.
When the unit is queried, it reports feedback on the specified input (source) or output (sink)
as follows:
•
There is no sink or source attached.
•
The connected sink supports HDCP, or the connected source is currently providing a
HDCP encrypted signal.
•
The connected sink does not support HDCP, or the connected source is currently
providing an unencrypted signal.
HDCP status of the current input can be viewed on the OSD bug. If the input is encrypted
the OSD bug displays an HDCP padlock symbol. The HDCP status of the currently selected
input, and the capabilities of the connected HDMI sink device, can also be viewed on the
AV
Controls
pane within the internal web pages of the unit.
HDCP Authorized
The HDCP Authorized function allows the DVS 605 HDMI inputs to be able to report as an
HDCP authorized sink or a non-HDCP authorized sink device to a source. This is especially
useful for sources that encrypt their output even if the source material does not require
HDCP encryption, which would then prevent content from being displayed on non-HDCP
compliant displays.
For example, if the user wanted to show a non-HDCP protected presentation from a
PC using the HDMI output of the PC, there is a chance that the PC encrypts the HDMI,
because it can see that the DVS 605 HDMI input supports HDCP authorization. If the user
were going to use only the HDMI output of the DVS 605 to a display (sink) that supported
HDCP, there would be no issue. However, if the user wanted to use the DVS 605 analog 15-
pin HD output to an analog sink, the green HDCP notification screen would be displayed,
due to the source unnecessarily enabling encryption on its HDMI output.
By disabling HDCP authorization on one of the DVS 605 HDMI inputs, the PC with
non-HDCP protected content determines that the signal path does not support HDCP, and
therefore does not encrypt its output. With HDCP authorization disabled on the
DVS 605 input, the user is be able to view their non-HDCP protected content from any
video output of the DVS 605. With HDCP authorized disabled on an input, if HDCP
protected content is selected on the source, the source either simply mutes its video output
to black, or displays a warning message to the user.
Genlock/AFL modes
The DVS 605 has the ability to lock the output vertical refresh rate to the selected input
signal vertical refresh rate (AFL), or to an applied SDI Genlock signal (SDI models only).
The three available modes for genlock are:
•
Off
— A free running pixel clock is generated internally by the DVS 605.
•
Input AFL
— This mode locks the output vertical refresh rate to the vertical refresh
rate of the currently selected input using Extron Accu-Rate Frame Lock technology to
ensure no frames of the input are repeated or dropped due to frame rate conversion.
This mode results in glitches or interruptions in output sync when a new DVS 605 input
is selected, or when a new signal has been routed to the DVS 605 selected input,
as the DVS 605 locks to the vertical refresh rate of the new input. If no input signal is
detected, or if locking to the input signal would result in a >165 MHz pixel clock, a free
running pixel clock is generated by the DVS 605.
