Ad Insertion

Ad Storage and Management

The StreamLiner product line sits at the heart of Harmonic’s ad insertion platform. StreamLiner provides the industry's most flexible and cost-effective video recording and streaming solution for delivering video services. StreamLiner is an optimized software architecture that turns standard server hardware into specialized, high-performance video servers designed to support video-on-demand (VOD), near video-on-demand (NVOD) and ad insertion applications.

StreamLiner’s high-performance solution based on common hardware delivers the industry’s highest stream density and provides extreme deployment flexibility, high scalability and superior economics. StreamLiner provides price, performance and feature advantages when compared with proprietary hardware solutions.

Each StreamLiner node provides self-contained storage and streaming resources comprised of chassis, control processor, RAM, direct attached storage, storage expansion modules and network interfaces capable of serving hundreds of simultaneous ad streams. The modular design of the Harmonic product architecture solution allows it to scale from hundreds of streams on a single server to tens of thousands of streams across multiple server nodes.

StreamLiner Ad Server interfaces

In order for the StreamLiner ad server to operate in an automated manner within an ad insertion system, it interfaces with multiple components in the system:

  • Ad Splicer – StreamLiner ad server utilizes standards based interfaces, specifically SCTE 30 standards for interaction with one or more ad splicers such as the ProStream 2000.
  • Traffic and Billing – The StreamLiner ad server interacts with both proprietary and standards based traffic and billing systems relating to scheduled playout of ads.
  • Offline Encoder – StreamLiner is capable of receiving compressed ad files from multiple sources such as the CLEARcut offline encoding studio.
