Insight, which has VOD deployed in north of 13 systems, is leveraging a "privacy mode"-enabled version of Harmonic's Narrowcast Services Gateway (NSG). The operator added the capability via a software upgrade to its deployed NSGs.
Harmonic said the platform will enable Insight to deliver larger libraries of VOD content via IP-based video transport streams, but ensure that only authorized users can access premium and other subscription-based fare.
"As the consumer migration to digital cable continues and VOD usage accelerates, the ability to scale in step with demand and, at the same time, securely transport video assets to the home is a critical business issue," said Patrick Forde, Insight's VP of engineering, video platforms, in a statement. "Streamlining our content protection scheme with Harmonic's solution provides Insight with a single-system solution for VOD delivery."
The use of real-time encryption (for more on this subject, please see this story) is considered more scalable than traditional pre-encryption systems, which can require operators to store multiple versions of a program, even for something as simple as a version for regular play out as well as one to support "trick play" functions (fast-forward, rewind, etc.).
