Restrictions for Video Content with 4K Resolution on the SV-
4K Media Player
Before preparing video content with 4K resolution for the SV-4K media player, consider
the following restrictions:
l
H.264 video encoding is not supported. Be sure that your content tools support
H.265 encoding.
l
Videos with 4K resolution are not supported for HDMI-In streaming.
l
Display of dual 4K video regions is not supported.
l
The 4K video region should be played in the primary video region only. A
secondary video region can support up to HD (1920x1080) video resolution.
l
4K video can be displayed in full ultra HD resolution (3840x2160) when using any
of the Cisco StadiumVision Director templates using the primary video region.
l
No luma key can be applied to 4K video content. Luma keying is only supported
with 4K for dual video when an HD video in the secondary region uses a luma key
over a 4K video in the primary region.
l
The Screen Template editor in Cisco StadiumVision Director presents all region
sizes based on an HD 1920x1080 canvas size—do not configure templates
based on the ultra HD size of 3840x2160 when using a 4K display.
l
If you are using a 4K display, you must configure a fixed resolution value of
3840x2160x60p in the sv4k.videoMode serial command in the TV display
specification.
For more information about how to specify the TV display resolution, see the
“Configuring Resolution Under Control Panel Display Specifications” in the

Macroblocking
Video content that contains large IFrames can cause macroblocking during playback
on SV-4K and DMP-2K media players. Macroblocking is a video artifact where areas of
a video image appear as small blocks or squares as shown in the following figure.
