As the successor to the market-leading ProStream 9100 stream processor, the software-based ProStream X system allows users to leverage the versatility and flexibility of a software-based infrastructure. This platform integrates 10Gbps throughput with a variety of advanced video processing applications, including multiplexing, stitching, redundant switching, and DVB CSA3 encryption. ProStream X can also serve as a high-throughput video gateway platform, featuring socket address flipping and ASI to IP conversion capabilities.
In addition to high throughput and multiplexing, ProStream X can also function as a DVB-T2 gateway. ProStream X is capable of encapsulating multiplexing into a DVB T2-MI stream, providing signals, transmission, and synchronization parameters for DVB-T2 modulators. It also has the ability to apply DVB-T MIP insertion, which inserts synchronization markers into the DVB-T transport stream.
ProStream X operates on a 1RU HPE® custom server and is paired with the Harmonic Electra®X2 advanced media processor, providing a compact solution for encoding and distributing high-quality IP and ASI video streams. This high-density architecture reduces the rack space required to meet fluctuating stream processing demands, helping operators lower capital expenditures and operational costs. High reliability and simplified maintainability deliver a unified experience for high-throughput stream processing with low total cost of ownership.
ProStream X supports SD, HD, and UHD formats as well as codec formats such as MPEG-2, MPEG-4 AVC, HEVC, and AVS. The device offers multiple deployment modes to perfectly meet infrastructure requirements, including servers with ProStream X, virtual machines with XVM, and bare-metal installations with ProStream Docker.
Device Advantages
Scrambling: ProStream X is integrated with major Conditional Access Systems (CAS) and is the first stream processing platform to offer 128-bit DVB CSA3 encryption support, certified and integrated by Cisco and Irdeto, making it the most secure stream processing solution for distributing UHD broadcast services. It also supports DVB CSA2, AES, and BISS fixed key scrambling, as well as a special scrambling mode for video on demand.
ProStream scrambling technology is renowned in the industry for its stability and high performance. The ProStream X platform can scramble any format of video, audio, and data elementary streams (such as MPEG-2, MPEG-4 AVC, HEVC, AC-3, AAC, HE-AAC), as well as multiplex MPEG TS. This solution can be easily integrated into existing architectures, reducing costs and complexity by minimizing the need for multiple devices in cable systems, satellite, or IPTV.
Perfect Statistical Multiplexing: Harmonic's DiviTrackIP™ This option integrates statistical multiplexing and IP switching by connecting the ProStream X system with remote Harmonic Electra X2 encoders over LAN or WAN, allowing any ProStream X in the network to efficiently manage the encoder's statmux pool. ProStream X also supports regional statistical multiplexing capabilities for the terrestrial market, allowing a single encoding instance to be part of multiple DiviTrack IP pools. This feature meets the demand for encoding and generating localized TS with common (shared) and unique regional channels.

Technical Advantages
High Throughput Video Processing: ProStream X offers four 1GbE, dual 10GbE, or ASI I/O options. The high throughput 10GbE option supports up to 1000 transport streams and 2000 audio and video services for simultaneous multiplexing and scrambling. Video gateway features include UDP multicast address modification, ASI to IP conversion, and IP mirroring. The dual 10GbE interfaces also reduce the number of required router ports and enable a simplified IP addressing scheme.
High reliability and ease of operation: The ProStream X platform supports hot-swappable fan components and dual redundant power supplies, making routine maintenance very simple. Replacing processors and I/O modules is both quick and convenient. These thoughtful maintainability features enhance system reliability and reduce downtime.
Control and Management: Processing on the ProStream X can be easily configured and controlled through Harmonic's NMX™, a Digital Service Manager video management system, which is a service-oriented solution for large-scale configuration, monitoring, and automated redundancy in centralized or distributed architectures. An intuitive, user-friendly web-based standalone GUI control method is also provided.
