Harmonic's Cloud-Native Media Processing Solution Supports High-Quality Video Delivery at Low Bit Rates

SAN JOSE, Calif. — Sept. 12, 2019 — Harmonic (NASDAQ: HLIT) today announced that its cloud-native media processing software and content-aware encoding (CAE) technology is powering Sky Italia's OTT streaming services. The Harmonic solution is integrated into the Sky Italia hybrid cloud software-defined streaming platform. Leveraging the latest advancements in pure software architecture, the Harmonic solution provides Sky Italia with the agility, flexibility and scalability to speed up the launch of new premium services and enable delivery of superior video quality at low bitrates.

Sky Italia's solution for its linear video streaming platform is based on Kubernetes and microservices to serve event-based and 24/7 channels on OTT platforms. Adhering to these requirements, Harmonic's VOS® Cluster software dynamically controls and optimizes Sky Italia's on-premises and cloud video-processing resources.

"To ensure the success of our next-generation streaming services, delivery of exceptional video quality and the ability to quickly adapt to changes are critical factors," said Gabriele Ubertini, director of technology engineering and innovation at Sky Italia. "Harmonic's cloud-native media processing software aligns with our choice of moving resources to Sky's software-defined streaming infrastructure, while allowing us to be nimble. Using CAE, we can deliver stunning video to a larger group of subscribers, providing a better quality of experience to those in areas with challenging bandwidth availability."

Sky Italia will use Harmonic's VOS software for OTT media processing in on-premises datacenters integrated with the Sky Italia architecture, which leverages Kubernetes and a SMPTE 2022 uncompressed multicast video network. By enabling Sky Italia to dynamically control and optimize its video processing resources, together with their blueprint for an open-source ecosystem, the VOS solution will dramatically accelerate time to market for new channels. EyeQ™ CAE will be used to significantly reduce Sky's bandwidth requirements, decrease CDN costs and improve QoE.

"Sky Italia asked for a highly available and scalable streaming solution for outstanding video quality and state-of-the art ABR packaging. We went above and beyond in meeting these requirements," said Ian Graham, senior vice president of international sales and video services at Harmonic. "Having an elastic and always-up-to-date media workflow will give Sky Italia serious competitive advantages, enabling it to launch services faster and scale up seamlessly."

Harmonic will showcase its latest video streaming innovations at IBC2019, Sept. 13-17 in Amsterdam at Stand 1.B20. Further information about Harmonic and the company's solutions is available at www.harmonicinc.com.
