Advanced Capture Card Features for Professionals

Powerful hardware scaler

Adjust the incoming video size to your requirements.

A captured frame can be scaled up or down within a 4K x 4K range using a high quality polyphase filter. The scaling process reduces overall DMA bandwidth by ensuring any downscaling is performed on the capture card before data is transferred to the destination. Any of the 16 MultiStream input clients can be up or down scaled independently.

MultiStream Technology

Independently control multiple instances of a capture from a single input source.

MultiStream technology provides DMA support for 16 independent capture clients. Each client can have independent capture size (scale factor), frame rate, pixel depth, DMA destination and cropping rectangle.

MultiStream allows 'Preview', 'Capture' and 'Stream' clients with different bandwidth requirements to be supported from a single input source, without using the CPU.

Common hardware buffer timestamp

Synchronise video and audio data across all capture cards and inputs.

The Datapath hardware timestamp uses a common clock for both video and audio buffers. Hardware time stamping provides precise knowledge of when a frame is captured, allowing applications to synchronise multiple sources from multiple cards.

Unparalleled performance

Colour Space Conversion

An on-board colour space and format converter eliminates the need for user post processing. Vision supports a long list of formats including those most commonly used by hardware and software based video encoders such as NV12 & YV12.

Triple Buffer

Triple buffering prevents image tearing whilst allowing captured video to run at a user-specified frame rate which does not have to match the input frame rate. This is useful in high density systems where display capabilities and bandwidths can vary.

High Performance Data Transfer (DMA)

Fully accelerated allows high bandwidth video transfer without using CPU. Users get maximum system performance when running multiple captures in parallel, allowing scale-able systems to be built.

LiveStream capture

Low latency video and audio capture minimizes the delay prior to post processing.

An alternative to Triple Buffering is LiveStream Mode. LiveStream effectively bypasses the onboard triple buffer allowing the very latest video frame to be delivered to users with minimum latency. For applications where only one client is required, LiveStream offers the lowest possible capture latency.

Outstanding user experience

Global Support Team

With dedicated support personnel stationed in the United Kingdom, United States of America and Japan, Datapath are able to provide world class support when you need it most.

24/7 Operation

Datapath hardware is manufactured to ISO 9001 standards, each board is subjected to an automated solder paste inspection, automated optical inspection, x-ray inspection and an intensive production test. Components are chosen for maximum MTBF for long term reliability.

Rich UI

Fast start up time using the interfaces provided by Datapath, Microsoft and Linux.

Rich sample application available as standard fully demonstrates the capabilities of Vision capture cards.

Flexible EDID Management

Configure the capture card to force a particular input signal on the source. Importing and exporting system EDIDs allows for flexible system integration when moving to 4K UHD. The EDID can be displayed and configured in either 'Video Definition' or 'EDID' format.

Automatic Signal Detection

Simply connect the input cable to start capturing. Signal detection is provided by internal driver algorithms assisted by physical hardware measurements. This provides high speed and accurate signal detection for all signal sources, including less common non-standard sources.

Unlimited HDCP Capture Sources

When used in conjunction with Image graphics cards, there is no limit to view-able encrypted video content.

Comprehensive software development kits

Take advantage of the Vision features easily and quickly.

Datapath provide a SDK bundle including our own RGBEasy which has been optimised over 15 years. For off shelf compatibility with various applications, Microsoft’s DirectShow and Media Foundation is also supported.

Develop your software with confidence. Datapath's SDK is always built on previous versions ensuring backwards compatibility, meaning updates do not effect existing installations.
