Advanced Capture & Compression Technology
Capturing and encoding video for digital streaming
or storage is a key requirement for the professional
AV market. Users need to capture video and not only
send the data to the screen but transport compressed
video to online resources such as storage locations for
remote access or later retrieval. The Datapath
VisionHD2-SQX is an advanced video capture card
with SQX technology that allows captured video to be
additionally encoded into H.264.
Featuring three independent capture channels, the
VisionHD2-SQX allows users to capture two High
Definition 1920x1200p video feeds and directly
encode them into H.264 using the dedicated SQX
processor. Each encoded video can be configured by
the SQX media server for distribution over a network.
In addition, raw video can be captured rapidly
transferred to graphics hardware or system buffers for
viewing or further processing.
Datapath’s SQX encoding technology uses the global
H.264 standard for video compression. Multiple streams
of captured video can be simultaneously encoded and
streamed to different locations. The VisionHD2-SQX
can capture two 1920x1200 inputs, the encoding
engine can encode one channel at 60 fps or both at
30fps, allowing one stream to be broadcast over the
network and another to be stored to disk.
A single stream can be distributed to any number of

network locations all configured through a media server.
VisionHD2-SQX provides all features of the Vision
capture card including No Signal and Mode Change
support. Both features help provide a seamless stream
of data to the end point. When a video signal is
disconnected, No Signal frames are generated and
encoded at the current requested resolution, upon a
Mode Change, input frames are scaled up or down to
maintain the originally requested
encode resolution.
Advanced Capture & Streaming Technology
The RGBEasy SDK allows users to manage both the
Vision capture engine and on-board encoding processor.
The RGBEasy SDK, when used with the VisionHD2-SQX
,includes example code to achieve the following:
• Save input captures as H.264 video to disk
• Connect to Unicast & Multicast RTSP URIs for streaming H.264 video across a network
Using the SDK, users are able to specify encoding
parameters such as H.264 level, profile, bit-rate
and key frame interval. Full details are available at
