Visually Lossless Image Quality

The PURE3 codec utilizes the discrete wavelet transform - DWT,

rather than the more common discrete cosine transform - DCT, to

achieve the best results with both moving pictures and computer

graphic images. Applying the DWT and full 4:4:4 color quantization

ensures that image detail is not lost during the transform process.

PURE3 achieves highly efﬁcient, visually lossless coding, ensuring

accurate reproduction of any input format or resolution.

Low Latency

The PURE3 codec performs its transform with a single pass through

the data, delivering low and consistent latency. The encode and

decode process each require 35 ms, for a total system latency of

70ms.

Highly Efﬁcient Compression

The PURE3 codec uses a highly efﬁcient compression method that

exploits the visual perception characteristics of the human eye to

optimize compression efﬁciency. An array of compression controls

are available to ﬁne-tune the degree and nature of compression,

optimizing for target bit rate and application requirements.

Advanced Error Concealment

Real-world, switched IP networks are prone to unpredictable bit

errors, jitter, and out-of-order or dropped data packets. The PURE3

codec incorporates error concealment that ensures robust picture

delivery. It maintains stable video imagery under heavy packet loss

and errors are rarely noticeable, as typically only a small portion of

the image is brieﬂy affected.

VN-Matrix Product Series

The VN-Matrix family of products includes:

A VN-Matrix 250 Encoder and Decoder – VNE 250, VND 250 –

Streaming of HDCP-compliant HDMI and RGB, two-way audio,

Serial RS-232, USB keyboard and mouse

A VN-Matrix 325 Codec – VNC 325 3G-SDI – Streaming of

3G-SDI, HD-SDI, and SDI signals with embedded audio

A Enterprise Controller – VNM Enterprise Controller – Manage,

conﬁgure and control encoding, decoding, and recording devices

A VN-Matrix Single Channel Recorder – VNR 100 – Develop

systems that can simultaneously record and play back one or

many AV source streams with metadata

A VN-Matrix Multi-Stream Decoding Software – VNS 104 –

Decode one to four AV sources on a Windows PC platform

VN-Matrix 250 Series

The VN-Matrix 250 Series provides real-time transmission of high

resolution HDCP-compliant HDMI, DVI, or RGB video across

standard IP networks for use in live streaming, recording, and

playback applications. Designed speciﬁcally to support mission

critical AV applications, the VN-Matrix 250 Series supports

streaming of commonly used AV signals, including HDCP-encrypted

video. Both stereo analog and HDMI-embedded audio inputs are

supported, offering compatibility and ﬂexibility with digital and analog

audio formats.

HDCP Compliance

Today’s AV systems frequently use a completely digital processing

and switching architecture. Use of just one HDCP-encrypted

source such as a Blu-ray player, satellite receiver, or PC with HDMI

output can necessitate that the entire system be HDCP-compliant.

VN-Matrix250 encoders and decoders solve this problem with their

ability to stream HDCP-encrypted content from HDMI sources to

HDCP-compliant displays. VN-Matrix 250 encoders also include a

15-pin HD connector that accepts legacy analog video signals.

Extron Advanced High Resolution Video Processing

VN-Matrix 250 encoders and decoders provide advanced video

processing for high resolution signals up to 1920x1200 and

2048x1080. They include EDID emulation, Extron EDIDMinder

and KeyMinder

, which assure that connected sources and

displays power up and operate at optimal resolutions and

frequencies, and continuously verify HDCP-compliance, ensuring

reliable connections and quick stream switching. VN-Matrix250

encoders also support user-deﬁned capture and proﬁle storage

of custom resolutions and frame rates for legacy analog signals.

VN-Matrix250 decoders maintain the original source resolution or

scale to a deﬁned resolution that matches the connected display.

A genlock connection allows synchronized decoding of streams

across multiple decoders.

Flexible Audio Processing and Streaming

VN-Matrix 250 decoders output either stereo analog or HDMI-

embedded audio, providing compatibility with embedded display

speakers or existing audio systems. The VN-Matrix 250 encoder

includes a loop through connector, simplifying integration with audio

source equipment, and audio streams can break away from their

associated video source.
