iDPM Support for Full 4K 2SI Effects
Four iDPMs per keyer are used to fly a full 4K effect in 4K 2SI Frame Operating 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).
4K Mode and Image Store
In 4K Mode, images and image sequences imported into the Image Store cache will be
divided into four sub-images, and assigned Image IDs and descriptions to reflect their
association as a 4K image. For example, Image ID 1000 will load as IDs 1000, 1001, 1002, and
1003. The image descriptions will be 1000-1, 1000-2, 1000-3, 1000-4.
A tolerance of +/-10% of the width and height of an image is allowed. Stills, sequences, or
movies outside those tolerances will be center cut, the default for progressive images.
Two Image Store channels are automatically configured as 4K, Image Store 1 and Image
Store 5. Each source uses four channels.
Each of the four sub-images must be loaded starting in either Image Store Channel 1 or
Channel 5, then each sub-image in order of Image ID. For example, Image Store Channels:
• 1/2—1000/1001
• 3/4—1002/1003
-or-
• 5/6—1000/1001
• 7/8—1002/1003
Importing Images with Audio to Image Store
Images, image sequences, and movies with paired audio (stereo) can be imported into
Image Store cache, and/or saved to disk. The video with audio must also match the frame
rate; 59.97Hz, 50Hz, or 60Hz, otherwise only the video will be imported.
4K 2SI (2 Sample Interleave) Modes and 2D DPMs
Three 4K Keyers (Keyers 1,2 or 1-3) are available per 4K M/E, up to twelve on a 4-M/E
switcher. Enabling a 2D DPM on a 4K key, is the same as in non-4K modes.
iDPMs are not supported in 4K 2SI mode currently but if used they will replicate the input of
sub-image 4. This will have the affect of down sampling the image to a pixel replicated
1080p image on-screen. This may be sufficient quality for some uses.
