DX-4400 4K 3G-SDI Text & Graphics Overlay Inserter (OSD) with SDI Loop Output

The DX-4400-TI-4K - 3G-SDI Video Text and Graphics Overlay Inserter product is an upgraded version of the base DX-4400-TI-2K product with the addition of support for a single channel of video operating at resolutions of either 4K UHD or 4K Digital Cinema Initiatives (DCI) using Dual-Link 3G- SDI configured with Quad and 2SI mapping.

User Configuration, Management & Control

An integrated ARM SoC supports enhanced text, telemetry data, image overlay including graphic widgets, 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.

Interactive Graphic Overlay Designer Interface

The Interactive Graphic Overlay Designer user interface (UI) offers the user a WYSIWYG method to configure the video text and graphic overlay information using a USB mouse and keyboard attached to the DX-4400. Overlay text, images and graphical components can be placed, sized and their attributes (color, font etc.) configured and modified as required directly while the user observes the video overly display on the output video. RS-232 and UDP data streams can be parsed and dynamically overlaid onto the output video stream.

A YouTube video demonstrating the use of the Interactive Graphic Overlay Designer UI is shown below.

SD, HD, FHD, 2K and 4K Modes of Operation

In the SD, HD, FHD, 2K and 4K Modes of Operation, the unit passes all video content* (on the primary video input) including audio channels and embedded metadata. For video resolutions up to 2K, 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 the respective SDI input. However, PiP is not supported at 4K resolutions since both 3G-SDI inputs are required for Dual-Link operation and Quad and 2SI mapping.

1) 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.

2) 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.

3) 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.

4) 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, FHD (3G-SDI) modes listed in the product specifications. Ancillary data from SDI input 1 passes through the unit to the output.

5) 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 the SDI Input 1 port.

4K Modes of Operation

In addition to the above Modes of Operation, the 4K version has three additional user selectable 4K Modes of Operation, each offering a different set of features and functionalities.

1) Dual Link 4K Text & Graphics Overlay Inserter

The unit provides a Text & Graphics Overlay Inserter for one channel of 4K video transported as SMPTE Dual-link (Quad and 2SI mapped) 3G-SDI video. ANC data pass-through is NOT supported.

2) Low Latency - Dual Link 4K Text & Graphics Overlay Inserter

The unit provides text and graphics overlay for one channel of 4K (Quad and 2SI mapped) video transported in the SMPT Dual-link 3G-SDI modes without frame buffers in the video path. Ancillary data pass through is supported in this mode of operation.

3) Digital Zoom - Dual Link 4K Text & Graphics Overlay Inserter

The unit support text and graphics overlay for one channel of 4K (Quad or 2SI mapped) video transported in the dual-link 3G-SDI format. For 2SI mapped video only, the input can be digitally zoomed. Ancillary data pass-through is supported in this mode of operation.
