Extron electronics Quantum Ultra Series User Manual page 45

A maximum of 10 canvases can be defined for each Quantum Ultra Series chassis, with
each canvas able to support up to 128 window presets associated with it. All canvases
(output groups) must be operating at refresh rates that are factors of each other to be
properly supported by the HyperLane bus (for example, 60 Hz and 30 Hz or 50 Hz and
25 Hz).
Output format
Each output group (canvas) defined in VCS can be formatted as HDMI, DVI, or Auto.
When set to Auto (the default), the output format is applied based on the EDID of the
display (see the VCS Help File for instructions on configuring and grouping the displays).
The format selections for a canvas have the following results:
HDMI — With this selection, the AVI info-frame packet and a blank audio payload are
•
included.
• DVI — This selection does not include the info-frame packet or blank audio.
• Auto — With this selection, an HDMI sink device format is determined by the
detection of a valid CEA extension header in the second block of EDID data.
HDCP mode
Using VCS, you can select the HDCP mode, which specifies whether the Quantum
Ultra Series processor encrypts source content. The processor can be set to always
encrypt HDMI data, to never encrypt (Off option), or to not encrypt after attempting
unsuccessfully to exchange keys with the target display for 1 minute (see the VCS Help
File for instructions on using this option).
Source up-scaling
The on-board scaler on the output card provides up-scaling of live video sources.
Independent horizontal and vertical scaling is possible up to 32 times the native
(outgoing) resolution. For example, a source of 1920 x 1080 pixels can be scaled up to
approximately 61,440 x 34,560 pixels.
