Belden Grass Valley K-Frame - 4 K 2 D-Dpms; 4 K Video and Key Sources; Idpm Support for Full 4 K 2 SI Effects

366 K-FRAME — User Manual
Section 8 — Advanced Operations
When placed in a 4K Frame Operating Mode, two physical VPEs (Video
Processing Engines) are used per logical ME to automatically configure 4K
MEs, with three keyers each. Every two full VPEs starting with ME-A1 and
ME-A2 will be acquired as a logical 4K ME. The Controller ME (ME-CT), is
a 1080p resource in 4K mode. See the K-Frame Kayenne/Karrera/GV Korona
Installation & Service Manual.
MEs are placed into Split Mode in order to configure the system for three
4K keys.
CAUTION Keys must remain split between the Primary (Key 1-3) and Secondary (Key
4-6) partitions for an ME to function properly in 4K mode.
4K Video and Key Sources
4K video and key sources are configured for use prior to operation. Once a
4K source has been configured, it is previewed and taken to air the same as
any other source, either as video or key. See the K-Frame Kayenne/Karrera/
GV Korona Installation & Service Manual.
In 4K 2SI mode, two pixels from each of the four inputs are layered to create
one 4K image.
In 4K Quad mode, each quadrant of video from the 4K source (for example
a 4K camera in 4K Quad mode) is one quarter of the 4K source’s image.
Four physical inputs, each with one quarter of the 4K image, are passed
through the switcher.
4K 2D-DPMs
In 4K Mode, logical 4K MEs have three keyers. 2D-DPM effects can be
enabled for each, up to twelve for 4K 2SI or one for every two MEs in Quad
mode. 2D-DPMs are delegated to 4K keyers in the iDPM, Transform,
Keyers 2DPM menu (as with any keyer) or from the Control Panel (
Enable/
Delegate DPM Channels on page 113).
Note iDPMs are not supported in 4K Frame Operation Modes, currently.
iDPM Support for Full 4K 2SI Effects
Four iDPMs per keyer are used to fly a full 4K effect in 4K 2SI Frame Oper-
ating Mode. Up to four 4K iDPMs are possible with 16 physical iDPM
resources licensed and acquired. See the K-Frame Installation & Service
Manual for physical resource allocation between suites and iDPM licensing
instructions.
When an iDPM is selected in 4K 2SI mode, four sub-images from the keyer
source are delegated to four iDPMs. This allows you to create a full 4K
iDPM effect when the keyer source image is 3840x2160 (a 1080p image will
be replicated to four iDPMs).
