Video Stream Processor & Gateway


The Harmonic ProStream® X software-based stream processing and gateway provides the best-in-class, high-performance stream processing for mission-critical broadcast, cable, satellite, terrestrial, IPTV, and OTT delivery applications. Benefit from a variety of advanced video processing capabilities, including multiplexing, scrambling, splicing, and blackout switching.

As the successor to the market-leading ProStream 9100 stream processor, the software-based ProStream X system allows users to leverage the versatility and agility of software-based infrastructure. The platform integrates 10Gbps throughput with a variety of advanced video processing applications, including multiplexing, splicing, blackout switching, and DVB CSA3 encryption. ProStream X also serves as a high-throughput video gateway featuring socket address flipping and ASI-to-IP conversion.

On top of the high throughput and remultiplexing, ProStream X can be used as a DVB-T2 gateway. ProStream X is capable to encapsulate a multiplex into a DVB T2-MI stream, providing signalization, transmission, and synchronization parameters to DVB-T2 modulators. It also has the capability to apply DVB-T MIP insertion which inserts synchronization marks in the DVB-T transport stream.

ProStream X runs on a 1-RU COTS HPE® server and pairs with the Harmonic Electra® X2 advanced media processor to deliver a compact solution for encoding and distributing superior-quality IP and ASI video streams. This high-density architecture reduces the amount of rack space required to meet fluctuating stream processing requirements, helping operators reduce CAPEX and OPEX. High reliability and simplified serviceability result in an all-in-one-box experience for high-throughput stream processing at low TCO.

SD, HD, and UHD formats, and MPEG-2, MPEG-4 AVC, and HEVC codecs are all supported on ProStream X. This appliance is available in several deployment models for a perfect fit with infrastructure requirements, including a server with ProStream X, a virtual machine with XVM, and a baremetal installation with ProStream Docker.
