8.2 Video/Audio Setting
Resolutions
– Use Input: Will pass the received video resolution to the endpoint.
– 4K: Scale to UHD (3840x2160).
– 1080p: Scale to Full HD (1920x1080)
– 720p: Scale to HD (1280x720)
Frame Rates
– Use Input: Will pass the received video frame rate to the endpoint.
– 60 Hz: Fixed Frame Rate of 60 frames per second.
– 50 Hz: Fixed Frame Rate of 50 frames per second.
– 30 Hz: Fixed Frame Rate of 30 frames per second.
– 25 Hz: Fixed Frame Rate of 25 frames per second.
– 24 Hz: Fixed Frame Rate of 24 frames per second.
Path Policy – Dropdown menu with the following options.
– Dynamic: Uses the EDID read from the connected endpoint. If the endpoint EDID supports
the current source's incoming audio format, the pass-through path will be used. If the
endpoint's EDID does not support the current source's incoming audio format, the down
mixed path will be used.
– Pass-thru: Pass-thru the HDMI audio format to the endpoint.
– Downmix: Uses audio processing to downmix the audio to 2 channel PCM.
NOTE: Scaling HDCP 2.2 sources to a HDCP 1.4 sync device requires the resolution input of the
HDCP 2.2 source to be 4K 60 4:2:0 8Bit or below.
For a Basic understanding of how these options affect the system review the following:
Use Input resolution and frame rate
– Virtually no switching latency, always less than 120 microseconds
of video latency.
– Output colorspace is the same as the source.
– Video latency depends on display to source synchronization time.
– HDR supported.
– 3D modes supported.
Scale video output resolution only
– Very low switching latency (less than 4ms).
– Output colorspace is always RGB 8bit.
– Video latency depends on display to source synchronization time.
– Display timing remains constant. There is no need to resync on
input changes.
– Switching time is dependent on the network switch.
For switches with the IGMP FASTLEAVE feature enabled,
switching time is < 0.1 seconds.
– Output colorspace is always RGB 8bit
– Latency is never less than one frame, but never more than two
frames.
– Video stutter may occur due to frame rate conversion frame slips.
