FEATURES
DESCRIPTION
The VisionAV-HD has three independent video capture
•
Triple channel PCI Express capture card
inputs - two supporting High Definition capture and a
•
4 Lane PCIe bus, Net 1.6 GB/s total capture bandwidth
third supporting Standard Definition composite video. The
•
Frame buffer memory - 2 x 256MB
•
Direct DMA to graphics memory of third party graphics
VisionAV-HD also adds multiple channels of audio capture,
which can be synchronised in software using time stamping
with all video capture channels.
cards
•
Both DVI High Definition inputs support HDMI, DVI, RGB
and Analog Component (YPbPr) input via a DVI-I connector,
at resolutions up to 4096 x 4096 pixels and supports 1080p
(1920 x 1080) at 6o frames per second.
Standard Definition is input as composite video on a single
RCA connector and can auto-detect between PAL, NTSC
Balanced (XLR) and Unbalanced (RCA) audio capture
from optional audio module (AM2)
•
All standard Vision range features
•
Datapath unified Windows driver supports XP and later
operating systems and all Datapath PCIe capture cards
•
Datapath Linux driver supports common Linux
distributions (audio support*)
and SECAM formats.
The VisionAV-HD captures all three video channels
Two DVI-I Capture Channels:
simultaneously and triple buffers them into onboard
•
HDMI/DVI/RGB/YPbPr video capture
•
HDMI embedded Audio Capture and streaming
•
Low input to 0utput capture latency
storage for tear free video, alongside an audio stream that
can be selected from one of the HDMI or one of the analog
audio ports. This data can then be processed and copied
using DMA transfers to the host system for display, storage
or streaming.

SOFTWARE CAPABILITIES
VIDEO STREAMING
DirectShow drivers for WDM Streaming driver supports the
following applications, to encode, record and stream video
over networks or the Internet:
•
Microsoft Media Encoder®
•
VLC
•
VirtualDub
•
Any other DirectShow encoding software
For streaming applications, the VisionAV-SDI can be used
with Windows Media Encoder to compress and stream
captured video. To replay the video, use Windows® Media
Player.
Timestamp support for streaming synchronisation
•
Synchronisation of multiple inputs across multiple
cards
•
Synchronise systems using network clock
synchronisation
•
For edge blending and other applications
Flexible and configurable EDID Management
•
Allows programming of custom EDID parameters for
Capture cards
Any application compatible with Windows® DirectShow
technology can use the VisionAV-HD due to it built-in WDM
support.
AUDIO FEATURES
Input and output connection via the Audio Breakout cable
which is supplied with the optional AM2 audio module
attached to a 15 pin high density D-type connector on the
Audio Module. The physical connections comprise of:
•
Left and right balanced audio input on female XLR jacks
•
Left and right unbalanced line inputs on female RCA
connectors
•
Left and right unbalanced line outputs on female RCA
connectors for direct passthrough of selected analog
input
Low Input to Output Capture Latency
•
DMA to third party graphics vendors back and front
buffers via Direct3D
Flexible input/output mixing capabilities.
•
Compatibility with AMD DirectGMA
Supports audio capture to the PCI Express bus at popular
sample rates from 44.1 to 96 ksamples/s at 16 bits/sample.
•
Compatibility with Nvidia GPUDirect
Playback and mixing of HDMI embedded audio.
•
Enables cropping support in DirectShow on all inputs
•
Supports Start and Stop trigger interface on all Visi0n
inputs
DATAPATH VISION SOFTWARE
The VisionAV-HD is supplied with a powerful sofware
application for configuring the format of the input sources
and displaying the data.
Simply connect your video source into the card, run the
VisionAV-HD application to automatically detect the
video source format and display the captured video in a
window on your desktop.

•
Multiple cards per system, 16 streams per
input
Frame sync and time stamping
DirectShow interface
The RGBEasy API for advanced audio and video
control
Fully integrated for use with Datapath Wall
Control software for video wall applications
MULTISTREAM
Datapath’s MultiStream feature is available on all Datapath Capture cards and enables multiple independently
formatted video streams to be setup in parallel.
Each stream can be formatted completely independently and individual selection of resolution, colour space, and
cropping region can be set for each stream. This maximizes bandwidth utilisation of the capture card PCIe interface,
and also simplifies development tasks for application developers who does not need to implement video stream
reformatting separately
GRAPHICS CARD INTEGRATION
When the VisionAV-HD is used with a Datapath graphics card, it is able to transfer the data directly to the graphics card thereby
increasing performance and allowing both sources to be viewed at full frame rate.
When the video data is displayed on a non-Datapath graphics card, the VisionAV-HD may still be able to boost performance by
using the graphics card’s DirectGMA interface to transfer directly to its off-screen memory, for example AMD DirectGMA and
Nvidia GPUDirect. This is dependent upon the graphics card driver software capabilities.
The VisionAV-HD is an ideal solution for applications that require both a real time camera feed, with synchronised audio, as well
as high resolution image capture at full frame rates.
