AccuStream Express HD+
High Resolution DVI, RGB, HDTV, Monochrome & Standard Definition Video Formats

The AccuStream™ Express Series of frame grabbers and video streamers is the most advanced, most versatile series of products from Foresight Imaging. AccuStream Express HD+ provides video capture from all popular high resolution and standard definition video sources: DVI, RGB, YPbPr, HDTV, monochrome, S-video and composite color. Physical input connectors on the board are HDMI-style DVI, DVI-I, and S-video. Up to 170 MHz pixel rates and up to 2048 x 2048 pixel resolution are supported. The extreme performance of AccuStream Express HD+ is due to the PCI Express x4 bus design, delivering sustained performance to system memory of 750 MB/second. For example, AccuStream Express HD+ can stream to memory 1080p HDTV video without dropping any frames.

Accuracy

The AccuStream Express HD+ delivers extreme accuracy and image quality for demanding customers with high resolution and precision applications. Extremely low pixel jitter of ±0.5 ns, superior analog design, and a 59 dB signal-to-noise ratio provide the accuracy and image fidelity required of high performance applications. For superior quality, 10 bit analog-to-digital converters are used throughout. Color video may be stored as 24 bit, and monochrome video at 8 or 10 bit. Pixel formats include RGB 24, RGB 32, RGB 5:5:5, RGB 8, YCbCr 4:2:2, YCbCr 4:4:4, 8 bit monochrome, and 10 bit monochrome.

Performance

AccuStream Express HD+ achieves its extreme 750 MB/second sustained performance via its PCI Express x4 bus mastering design, scatter-gather technology, and double buffering. This high performance requires minimal CPU intervention so that the processor is free to work on other tasks or process the data immediately. Real-time display is simultaneously enabled by real-time transfer of image data directly to display card memory over the bus. AccuStream Express HD+ also features independent, dual video data paths, allowing for the simultaneous DirectDraw display of YCbCr 4:2:2 color video and the transfer of full 24 bit RGB video data for processing. All AccuStream Express boards include a real-time up/down video re-sizer/scaler which uses a polyphase algorithm for optimum image quality. The real-time scaler supports scaling images down to 4 x 4 and up to 2048 x 2048.

Video

AccuStream Express HD+ acquires images and video streams from both non-standard and standard video inputs from DVI, RGB, YPbPr, HDTV, S-video, composite color, and monochrome sources. Video input connectors on the board include an HDMI-style DVI connector (for DVI-D input), a DVI-I connector (for DVI-D, DVI-A, RGBHV, & monochrome inputs), and a S-video connector (for S-video & composite color inputs). Input resolution is up to 4 megapixels total area and pixel rates are up to 170 MHz. For fine-tuning of the video signal, gain, black level, white balance, and phase controls are provided. Separate H and V sync are supported. An external trigger is available. AccuStream Express HD+ is fully compliant with the DVI 1.0 specification.

Software

AccuStream Express HD+ is supported by Auto-SYNC™ ,Foresight Imaging's flagship automatic configuration software. Auto-SYNC ensures quick and simple installation and image capture by automatically configuring AccuStream Express HD+ to the incoming standard or non-standard video signal. Auto-SYNC automatically analyzes the incoming video signal and builds a configuration file. Use the configuration file as created or utilize the Auto-SYNC Wizard for simple, step-by-step video adjustments. AccuStream Express HD+ is supported by the IDEA (Imaging Development Environment for Applications) software development kit. By using IDEAT, developers have the confidence of knowing that they can write their applications once and have support built-in for the entire AccuStream Series. A WDM driver and a TWAIN driver are included to further simplify development and use of AccuStream Express HD+. With IDEA, ActiveX controls are provided to facilitate easy development with Visual Basic, Visual C++, and Visual J++. Extensive example programs (with source code) are provided with IDEA. Functions of the example programs include triggered acquisition, video streaming to AVI files, integration with Pegasus Imaging compression for streaming, overlays, and much more. Auto-SYNC, IDEA, example programs, and drivers are provided free of charge with each AccuStream Express HD+.
