DX-8000 - 12G-SDI 4K Dual-channel Text & Graphics Overlay Inserter with PIP and PAP Display

The DX-8000 is a high performance low latency Dual channel 12G-SDI 4K Video Text and Graphics Overlay Inserter supporting alpha blended text and graphics overlay/on-screen display (OSD). The unit supports standard definition (SD) video up to 4K UHD/DCI resolutions with less then one frame of video delay between input and output in the low latency configuration.

The product passes all video content including audio channels and embedded metadata. Either SDI input can be used for either a scaled dual picture-in-picture (PiP) or a side-by-side / picture-and-picture (PAP) display. Secondary SDI outputs provide a clean loop pass-thru output of the respective SDI input.

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 either of the video streams. 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/IP Ethernet connection. An interactive Web based user interface is available for configuration, management, maintenance and control.(See below.)

Interactive Graphic Overlay Designer User 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-8000. 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.

Modes of Operation

The unit has a number of user selectable Modes of Operation, each offering a different set of features and functionalities.

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, up to 4K video resolutions (listed below) complete with ancillary (ANC) data pass through. Digital zoom is supported for progressive video formats.

2) PIP Text & Graphics Overlay Inserter

This Mode supports a single 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 PAP configurations. In this Mode the unit supports text and graphics overlay functionality.Ancillary data from input 1 passes through the unit to the output.

3) 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.
