The DX-4400 is a high performance low latency single/dual channel SD/HD/2K/4K-SDI Video Text and Graphics Overlay Inserter supporting alpha blended text overlay / on screen display (OSD) on progressive, progressive segmented frame (PsF) and interlaced SD, HD, FHD, 2K, UHD 4K and Digital Cinema (DCI) 4K video formats.
An integrated ARM SoC supports enhanced text, image and graphics overlay, line/circle drawing and rotations. Up to 1,000 independent text fields, images and graphic elements can be overlaid (inserted) onto the video stream. An extensive command set allows for full control of size, font type, color, position, background color and full transparency control. The overlay data and user commands are delivered to the unit through the RS-232 (DB9 or USB) serial ports or via a TCP Ethernet connection. A Web user interface is available for configuration, management, maintenance and control.
The product passes all video content* (on the primary video input) including audio channels and embedded metadata. Either SDI input can be used for PIP and for a scaled dual (side-by-side) display. Secondary SDI outputs provide a clean loop pass-thru output of each input.
Modes of Operation
The unit has several user selectable Modes of operation, each offering a different set of features and functionalities.
NOTE: Based on customer feedback, additional Modes of operation are being added via firmware updates.
Dual Channel Text & Graphics Overlay Inserter
In this mode the product provides 2 video channels with separate text and graphics overlays for each channel. Each channel supports the SD, HD, and 3G video resolutions (listed below) complete with Ancillary (ANC) data pass through.
Low Latency Dual Channel Text & Graphics Overlay Inserter
This mode also offers a low latency setting in which the video path has 1 to 2 lines of frame of delay. In this configuration, zoom, Alpha Blending and PiP functions are not supported.
Zoom Dual Channel Text & Graphics Overlay Inserter
This offers a zoom control for each channel for progressive video formats at SD, HD & FHD video resolutions. Ancillary data pass-through is not supported.
PiP Text & Graphics Overlay Inserter
This mode provides a single channel text inserter with a main input and a secondary input. Both inputs have scaling capabilities to allow for use as Picture in Picture (PiP), split screen or side by side configurations. The unit has a single text and graphics overlay and supports the SD, HD, and 3G modes listed in the product specifications. Ancillary data from input 1 passes through the unit to the output.
Low-latency PiP Text & Graphics Overlay Inserter
This is a low-latency version of the PiP Text Overlay Inserter with less than one frame of delay from input to output. Input 1 does not support PiP or Zoom. Input 2 supports PiP and zoom. ANC data pass-through is supported on Input 1.
Dual Link 4K Text & Graphics Overlay Inserter
The unit provides a Text & Graphics Overlay Inserter for one channel of 4K video transported in the SMPTE dual-link (Quad and 2SI mapped) mode of operation. ANC data pass-through is NOT supported.
Low Latency Dual Link 4K Text & Graphics Overlay Inserter
The unit provides a low-latency Text & Graphics Overlay Inserter with only 1 to 2 lines of frame delay for one channel of 4K video transported in the SMPTE dual-link mode of operation. Ancillary data pass-through is supported in this configuration.
Zoom Dual Link 4K Text & Graphics Overlay Inserter
The unit provides a single channel text & graphics overlay for 4K (Quad or 2SI mapped) dual-link video. For 2SI mapped video, the input video can be digitally zoomed. me delay for one channel of 4K video transported in the SMPTE dual-link mode of operation. ANC data pass-through is supported.
NOTE: 4K support is a product license upgrade to the base 2K product.
