Unifying the entire media processing chain, from ingest through delivery, VOS SW Cluster allows content creators and pay-TV operators to launch new video channels fast, and to run simpler, leaner operations. As a totally infrastructure-independent media processing application VOS SW Cluster makes it easy for operators to migrate back and forth between bare metal datacenter computing, public clouds and private clouds. Having an elastic and always up-to-date media workflow enables operators to launch services faster, scale up seamlessly with operational efficiency, and ensure consistent functionality across all deployment environments, which includes delivering exceptional video quality at low bitrates. With a simple intent-driven user interface, and the capability to mix optimized and dynamic cost allocations, operators have more time to test new service offerings and focus on the creative side of their business.

VOS SW Cluster encompasses every component of Harmonic media processing as software. It embeds market-leading state-of-the-art micro services: ingest, playout, compression, encryption, packaging, origin server. Streamlined and consolidated workflows are built by simply selecting required capabilities and leveraging template-based workflows, allowing for rapid, consistent configuration of system resources. Natively built on a REST API, VOS SW Cluster offers seamless integration into existing operations, simplifying operators’ ability to add services to their workflow — or remove them — in a matter of minutes.

VOS SW Cluster Features

Built for the Cloud

As a cloud-native application, VOS SW Cluster assures scalability and agility. Support for private and public cloud deployment as well as bare metal environment, enables system access from anywhere in the world with an internet connection and let you work the way you want. Harmonic APIs provide hooks into your existing operations, simplifying the ability to add – or remove – VOS SW Cluster services in a matter of minutes.

PURE Power

Encoding and transcoding functionality on VOS SW Cluster is powered by the Harmonic PURE Compression Engine™, which provides support for a wide range of formats, codecs and encoding schemes to enable broadcast-quality video at low bitrates. An optional enhancement to the Harmonic PURE Compression Engine is the Harmonic EyeQ™ video compression solution, which provides a superior viewing experience while reducing bandwidth consumption by up to 50%.

Reduced CAPEX and OPEX

The broad capabilities of VOS SW Cluster converge broadcast and OTT media processing and delivery into a single, easy-to-use solution. Function integration built into the application reduces the number of devices required to build out a broadcast transmission chain, decreasing both capital and operating expenditures and delivering exceptionally low total cost of ownership (TCO).

Accelerated Time-to-Market

With VOS SW Cluster’s full complement of embedded workflow features, operators can easily add a new video channel to their lineup. This process is completely straightforward and requires just a few steps from the operator.
