ULTIMO, Australia - April 7, 2014 - PRLog -- Inventa Australia (http://www.inventa.com.au) has released a High-DefinitionText & Graphics Overlay card "VoverlayHD", that superimposes PC-generated High-Definition text, graphics and video onto input HD video, then realtime output the resulting video with overlay to SDI and HDMI output ports. Using on-board ICs to instantly mix host-generated bitmap with input video frames, VoverlayHD allows user software to instantly control every overlaid pixel on the output video frame in full 24-bit RGB Colour plus 8-bit Alpha Transparency Levels, quickly and easily creating unlimited video effects including speed-controllable motion text and graphics, timers, multiple video windows, etc. The main features of VoverlayHD include:

       --    Low-delay graphics overlay on live HD video using on-board hardware mixing engine without involving host CPU/GPU

       --    Full 256-Level Alpha blending control on every colour pixel with 24-Bit Colour mixed with incoming video

       --    HD/SD Input & Output up to 1920X1080-Pixels, 24/25/50/30/60/29.97/59.94/23.97Hz Frame Rates, Interlaced & Progressive

       --    SDI and HDMI  video Input/Output supported and software selectable: 3G-SDI, HD-SDI, SD-SDI, HDMI

       --    Simultaneous SDI and HDMI video output ports outputting same content

       --    Every output video frame can be grabbed and saved as graphics file and/or raw YUV file

       --    Instant overlay add / delete without visual delay on outputting video signal

       --    Un-limited PC-generated colour text, graphics and video can be overlaid simultaneously on incoming video

       --    Output video with overlaid graphics data is always visually synchronized with input video

       --    Up to 16 Multiple cards can be run on the same PC

       --    Full software control at application & SDK level on video Sync type, Mixing mode, Resolution, Progressive/Interlace etc

       --    Output ports can be software configured to display video only, video plus overlay, overlay only

       --    Internal, External and SDI Signal Sync Modes supported and software selectable

       --    Separate Reference Sync BNC Port available on card back panel

       --    Overlay Content can appear on output ports when no input signal is available

       --    SDI Input to Output Video By-Pass Relay (Video Pass-through) on PC power loss (reboot or powered off)

       --    Input SDI or HDMI Audio is passed onto Output Ports

       --    Live Video Preview on PC Screen in resizable floating window always displaying the output video content

       --    Overlay Text String support different colour, font name, size, background mode, transparency & Unicode

       --    Overlay Graphics Files support for BMP, JPEG, GIF, PNG, TIFF and Targa format

       --    Apply single or a range of “Transparency Colours” on Graphics & Text for Blue-Screen/Chroma-Key effect

       --    Overlay Timer support for time, date, mille-second, frame number

       --    Overlay Card Operation support for instant screen clear, area alpha change, area content rotation, port I/O selection, etc.

       --    Overlay Windows support for constantly displaying any window’s content to external HD Video Devices

       --    Constant Alpha Channel Value Change under software control for timing and increment

       --    Horizontal and Vertical Moving Text & Graphics Overlay with software configurable steps and times

       --    Instant Overlay Display to external HD Video Devices from multiple overlay items constructed & loaded

       --    Save and Open Overlay Item List Files for single-click and repeated use of multiple overlay items

Combining advanced DSP, FPGA and ample DDR memory on board, VoverlayHD is a “hardware graphics overlay device (http://www.inventa.com.au/hardwarevssoftwareoverlay.htm)” that uses on-board dedicated chips to instantly mix graphics data received from host PC with incoming video then output the mixing result immediately, resulting in low-delay, low CPU/GPU usage and high-quality video + overlay output. VoverlayHD has  on-board memory buffers available for application software to directly write and read all colour pixels realtime overlaid on the incoming video,
allowing easy and unlimited video effects creation using the full graphics processing power of the Windows operating system (GDI/GDI+/Direct3D etc.) --- graphics do not need to appear on PC screen to be overlaid on video: once some 4-byte ARGB values are written to memory the corresponding position on output video ports will immediately show the overlay ARGB content, regardless they are displayed or not on PC screen.  The hardware implemented 256-Level Alpha-Channel blending capability gives application software easy and instant control for any overlay items' visibility on the external HD TV, complicated multiple-item graphical overlay effects such as fade-in / fade-out flying text over live video etc. can be created within minutes, or pre-created into data file then start instantly in front of live incoming video with single-mouse click.

VoverlayHD can be used in many applications where flexible high-quality HD text, graphics and video are needed to overlay on live HD video in real-time:

--    Video Annotations with Scalable Fonts and Various Colours

--    Video Capture, Encoding, Streaming and Editing

--    Real-time Subtitle Insertion onto SDI/HDMI Video Signal

--    TV and Video Broadcasting Titling

--    Digital Signage and Advertisement

--    Dynamic HD Text, Lyrics and Logo Generation for Live HD Video

--    Industrial, Sub-Sea ROV Video, Medical Instrument and Aero-Space Video with Live PC Graphics Overlays

VoverlayHD runs on 32-Bit or 64-Bit Microsoft Windows XP, Windows Vista, Windows 7 and  Windows 8 operating systems, comes with full application software inc. C++, VisualBasic, C# source codes and Application User Manual (http://www.inventa.com.au/Product%20Release%20and%20Comme...), plus full Software Development Kit (http://www.inventa.com.au/Product%20Release%20and%20Comme...).  Moderate-Configuration Intel/AMD CPU PCs will all work well without expensive dedicated high-end hardware components.
