Harmonic ProStream® X


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, 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 sofware-based infrastructure. The platform integrates 10-Gbps 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, the ProStream X can be used as a DVB-T2 gateway. The ProStream is capable to encapsulate a

multiplex into a DVB T2-MI stream, providing signalization, transmission and synchronization parameters to DVB-T2 modulators. The ProStream X also has the capability to do DVB-T MIP insertion which inserts synchronization marks in the DVB-T transport stream.

ProStream X runs on a 1-RU COTS Intel® 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 resultin 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 severaldeployment models for a perfect fit with infrastructure requirements, including a server with ProStream X, a virtual machine with XVM and abaremetal installation with ProStream Docker.

Business Benefits


ProStream X integrates with major conditional access systems (CAS) and is the first stream processor to offer 128-bit DVB CSA3 encryption support, integrated and certified by Cisco and Irdeto, making it the most secure stream processing solution for distributing UHD broadcast services. DVB CSA2, AES and BISS fixed key scrambling are also supported, as well as trick mode for video on demand.

ProStream scrambling technology is known in the industry for its stability and high performance. The ProStream X platform can scramble any format of video, audio and data elementary stream (e.g., MPEG-2, MPEG-4 AVC, HEVC, AC-3, AAC, HE-AAC), as well as multiplex MPEG TS. The solution easily integrates into existing architectures, and reduces cost and complexity by eliminating the need for multiple devices in distributed cable, satellite or telecom networks.

Statistical Multiplexing

Harmonic’s DiviTrackIP™ option integrates statistical multiplexing and IP switching by connecting ProStream X systems with remote Harmonic Electra X2 encoders across a LAN or WAN, allowing any ProStream X in the network to efficiently manage the encoders’ statmux pools. ProStream X also supports regional statmux capability for the terrestrial market, allowing a single encoding instance to be part of multiple DiviTrack IP pools. This capability answers the need to encode and generate regionalized TS’s with both common (shared) national and unique regional channels. The use of the regional statmux feature reduces the number of encoders required to support regionalized feeds and eliminates unnecessary national common program duplication.

Technical Benefits

High-Throughput Video Processing

ProStream X offers the choice of quad 1-GbE, dual 10-GbE or ASI I/O. The high-throughput 10-GbE option supports up to 1,000 transport streams and 2,000 simultaneous multiplexing and scrambling services. Video gateway capabilities include socket address flipping, ASI-to-IP conversion and IP mirroring. The dual 10-GbE interfaces also reduce the number of required router ports and enable a simplified IP addressing scheme.

High Reliability, Simplified Serviceability

Maintenance on the ProStream X platform is simplified with hot-swappable fan assemblies and dual redundant power supplies. Changing of processors and I/O modules is quick and easy. These thoughtful serviceability features improve system reliability and reduce the chance for downtime, increasing the opportunity to generate revenue.

Control and Management

Processing on the ProStream X is easily configured and controlled with Harmonic’s NMX™ Digital Service Manager video management system, a service-oriented solution for mass configuring, monitoring and automated redundancy in centralized or distributed architectures. An intuitive and user-friendly web-based GUI is also available.
