PURE3 Codec

PURE3^® is not just another repurposed codec that had been originally designed for digital cinema, security video, broadcast, or Internet streaming. Extron's patented PURE3 codec is a powerful, groundbreaking, purpose-built codec designed specifically for Pro AV applications. For over 20 years, Extron has been engineering video transmission and signal processing solutions that deliver uncompromised image quality and performance. By leveraging our expertise in video transmission and our knowledge of the Pro AV market and applications, we created PURE3 from the ground up to address the unique needs of the professional AV industry.

PURE3 is a unique wavelet-based compression technology that exceeds the performance characteristics found in standards-based compression systems. Most codecs make compromises in either image quality, bandwidth requirements, or latency. Extron’s no-compromise PURE3 codec offers the best off all three with its groundbreaking simultaneous delivery of high quality, low bitrate, and virtually no latency. Video signals are encoded with 4:4:4 color quantization, while maintaining original source quality and native resolution. The PURE3 codec also features advanced error concealment, providing high immunity to network errors such as bit errors, jitter, and out-of-order or dropped data packets. PURE3 error concealment provides robust picture delivery without the increased latency or bandwidth typically introduced by forward error correction – FEC systems.

Engineered by Extron from the Ground Up

PURE3 is different from most codecs used in the Pro AV industry today. It was developed from the ground up by Extron’s expert team of signal transmission and processing engineers. This unique, patented video processing technology sets the industry benchmark for visual performance. The PURE3 codec captures and preserves video and computer graphics signals at native resolution, aspect ratio, and frame rate, maintaining all pixel detail and motion information to ensure accurate reproduction of the original input signal. In addition, PURE3 capitalizes on periods of low motion with its exclusive Intelligent Selective Streaming technology that achieves incredibly low bit rates while maintaining visually lossless performance.

By developing our own codec, we are able to design to our own exacting specifications and have absolute control over the end product. We can continually refine the signal processing algorithms, enhance signal compatibility, and add features at will. This also allows us to quickly respond to market or technology-related advancements as they emerge and opens the way to accommodate application-specific requests from AV integrators.

Extron’s sophisticated video processing algorithms have been recognized worldwide with numerous patents.
