Page 25 of 125
Mode Description
Dual Link 4K Text
Inserter
( 4K TI )
The DX-4400 functions as a single channel, 4K Text Inserter (4Kl TI). Video inputs and
outputs operate as SDI Dual Links with each port operating at 3 GB/s supporting 4K video
at frame rates up to 30 fps.
➢
3840x2160 and 4096x2160 resolutions are supported.
➢
Ancillary data from the inputs is discarded.
➢
Zoom and PiP functions are not supported.
➢
If you switch into 4K mode without a having a 4K IP Core License File installed, the
video is disabled.
Low Latency Dual
Link 4K Text
Inserter
( L4K TI )
The DX-4400 functions as a single channel, 4K Text Inserter (L4K TI). Video inputs and
outputs operate as SDI Dual Links with each port operating at 3 GB/s supporting 4K video
at frame rates up to 30 fps. The delay is less than one frame.
➢
3840x2160 and 4096x2160 resolutions are supported.
➢
Ancillary data and audio from the inputs is transported to the outputs.
➢
Zoom and PiP functions are not supported.
➢
If you switch into Low Latency 4K mode without a having a 4K License File installed,
the video is disabled.
Zoom Dual Link 4K
Text Inserter
( Z4K TI )
The DX-4400 functions as a single channel, 4K Text Inserter (Z4K TI). Video inputs and
outputs operate as SDI Dual Links with each port operating at 3 GB/s supporting 4K video
at frame rates up to 30 fps.
➢
3840x2160 and 4096x2160 resolutions are supported.
➢
Ancillary data and audio from the inputs is transported to the outputs.
➢
Text overlay is supported for 2SI and Quad mapped video.
➢
High magnification zoom is supported for 2SI mapped video only.
If you switch into this mode without a having a 4K License File installed, the video is
disabled.
Low Latency Text
Inserter with PiP
( LPiP TI )
The DX-4400 functions as a Text Inserter with PiP (LPiP TI)supporting two inputs, one
overlay, and two identical outputs.
➢
Input 1 is the main input. The product automatically adjusts the output to match the
video detected on Input 1. All ancillary data (including audio) from input 1 is
transported to both outputs. This input has a latency of less than 1 frame from input 1
to output. Zoom and PiP functions are not available.
➢
Input 2 is a secondary input that is typically used for a PiP display. Ancillary data from
input 2 is discarded. Input 2 can be a different resolution or frame rate than Input 1,
but if Input 1 is progressive, then Input 2 must be progressive, and if Input 1 is
interlaced or PsF, then Input 2 can be progressive, interlaced or PsF.
➢
Input 2 can be down scaled and clipped.
➢
Input two can support high magnification zoom with a latency of 2-3 frames or can
have latency 1-2 frames with zoom limits of 100% for 3G, 150% for HD and 300% for
SD modes.
➢
All the supported video modes are available except for the 4K modes. Refer to the
Video Input Formats list (under § 1.1 Supported Functionality ) for the supported
modes.
Notes:
1) The Low Latency mode decreases the frame delay and is described in Section 3.9.6 Video Buffering and
Frame Delay.
2) The REM Command can be used to display the current Mode of Operation.
3.7.1 Set Mode Commands
The Set Mode (SM) commands are used to select the Mode of Operation for the DX-4400 product and optionally
assign the Serial Command Port to either the RS-232 Serial port or the USB Serial port.
