The Modes of Operation of the DX-4400 is configured by the user using the Set Mode (SM) Command are
described in the Table 6 below.
Table 5: DX-4400 Modes of Operation
Mode Description
Dual Text Inserter
( Dual TI )
The DX-4400 functions as a Dual Channel SDI Text Inserter (Dual TI ).
➢
An overlay layer is added to the video on Input 1. The output is available on Output 1.
➢
A different overlay layer is added to the video on Input 2 and the output is available
on Output 2.
➢
Input and 1 and 2 both pass all ancillary data including audio from the SDI input to the
corresponding SDI output.
➢
Zoom and PiP functions are not supported.
➢
All the supported video modes are available except for the 4K modes. Each output
will automatically adjust mode to match the signal on the corresponding input. Refer
to the Video Input Formats list (under §
1.1 Supported Functionality ) for the
supported modes.
Low Latency
Dual Text Inserter
( LDual TI )
The DX-4400 functions as a low Latency Dual Channel SDI Text Inserter (LDual TI).
The delay through the video path is less than one frame.
➢
An overlay layer is added to the video on Input 1. The output is available on Output 1.
➢
A different overlay layer is added to the video on Input 2 and the output is available
on Output 2.
➢
Input and 1 and 2 both pass all ancillary data including audio from the SDI input to the
corresponding SDI output.
➢
Zoom, Alpha and PiP functions are not supported.
➢
All the supported video modes are available except for the 4K modes. Each output
will automatically adjust mode to match the signal on the corresponding input. Refer
to the Video Input Formats list (under §
1.1 Supported Functionality ) for the supported
modes.
Zoom Dual Text
Inserter
( ZDual TI )
The DX-4400 functions as a Dual Channel SDI Text Inserter (ZDual TI)with zoom on
both video paths. No ancillary data is passed through.
➢
An overlay layer is added to the video on Input 1. The output is available on Output 1.
➢
A different overlay layer is added to the video on Input 2 and the output is available
on Output 2.
➢
PiP functions are not supported.
➢
All the supported video modes are available except for interlaced and 4K modes.
Each output will automatically adjust mode to match the signal on the corresponding
input. Refer to the Video Input Formats list (under §
1.1 Supported Functionality ) for
the supported modes.
Text Inserter
with PiP
( PiP TI )
The DX-4400 functions as a Text Inserter with PiP (PiP 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.
➢
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 must be interlaced or PsF.
➢
Both input 1 and input 2 can be down scaled and clipped, allowing for display as Side
by Side, or Split screen in addition to PiP display.
➢
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.
