PURE Compression Engine
Representing the latest advances in video encoding and transcoding, the PURE Compression Engine™ provides exceptional video quality, industry-leading bandwidth efficiency, and diverse format and codec support for all broadcast and multiscreen services. These capabilities are delivered from a software-based foundation that is not limited by the constraints of custom hardware. The PURE Compression Engine paves the way to the delivery of next-generation services such as UHD and 360° Virtual Reality video while reducing your organization’s CAPEX and OPEX. It also helps manage the transition from SDI to all-IP and cloud infrastructure, allowing your company to step from the headend into the data center whenever it’s ready.
The Harmonic PURE Compression Engine utilizes Harmonic’s market-leading experience in video compression algorithms and multi-pass encoding technologies to provide groundbreaking video quality at the lowest possible bitrates. In addition to delivering significantly improved efficiency and simplified upgradeability over competing encoder technologies, PURE Compression enables true codec independence. MPEG-2, AVC and HEVC streams are supported, as are the most common SD, HD and UHD content formats, as well as constant, variable and adaptive bitrate streaming.
Many of the algorithm and processing techniques developed by Harmonic over the past two decades are incorporated into the PURE Compression Engine. The software-based PURE Compression environment removes many of the restrictions and limitations previously inherent in ASICs, enabling more performance to be squeezed from existing, well-proven techniques. This added flexibility extends to deeper, more content-focused video analysis. For example, we now have the ability to support an arsenal of different motion-estimation algorithms and to apply them adaptively, depending on the content type.
