Electra X2S

A converged solution for superior encoding, multiplexing and network management

Electra X Advanced Media Processor

The Harmonic Electra™ X2S advanced media processor converges the essential components of a video headend onto a cost-effective 1-RU platform. Featuring integrated real-time encoding, network management, multiplexing, and high-quality graphics and branding, Electra X2S offers broadcasters, pay-TV operators and content providers market-leading video quality and increased operational flexibility.

Harmonic’s industry-leading function integration achieves its highest level in Electra X2S. Statistical multiplexing capabilities previously available only on Harmonic ProStream® stream processors, and management functionality from the Harmonic NMX Digital Service Manager™ come standard. The addition of on-board video graphics and branding bring new levels of workflow efficiency to the video delivery chain, a capability that also preserves video quality by removing the need to inject baseband components into the IP workflow.

Electra X2S Features

Video Compression Excellence

Delivering significantly improved efficiency and simplified upgradeability over competing encoder technologies, the software-based Harmonic PURE Compression Engine™ powers Electra X2S with true codec independence. MPEG-2, AVC and HEVC Main 10 transport streams are supported, as are the most common SD and HD content formats. For OTT applications, the optional EyeQ technology leverages the function of the human visual system to cut bandwidth consumption by up to 50% while ensuring delivery of consistent, superior-quality video to all devices.

Preprocessing

Advanced noise-reduction capabilities include Harmonic’s signature motion-compensated temporal filtering (MCTF) to enhance the appearance of incoming material. The Electra X2S processor also supports powerful deinterlacing to cleanly deliver progressive formats.

Statistical Multiplexing

The Electra X2S processor maximizes the efficiency and flexibility of multiplexing by integrating Harmonic Flextream IP statmux technology (formerly DiviTrackIP™) in the same chassis as the encoder. Unique capabilities include support for distributed statmuxing and Flextream Convergence, in which a target average bitrate can be set for each service within a statmux pool — especially useful for ATSC broadcasters with Channel Sharing Agreements.

Network Management

Easy to use, the Electra X2S user interface builds on NMX to offer a powerful set of tools for monitoring and managing compressed digital video and audio systems. Service status, including alarms, is passed through to the top level, ensuring that problems are quickly detected and resolved. Adding, reconfiguring or removing services or equipment is fast and easy.

High-Quality Graphics and Branding

Electra X2S possesses a unique set of graphics and branding capabilities tailored to the requirements of content distribution and service delivery. Dynamic text, regulatory and station logos, and rich branding elements can be easily added to video channels. Up to eight graphics layers are supported, and graphics elements can be shared across all distribution channels, including mobile devices and the web.

Audio Processing

Electra X2S supports embedded audio and can natively encode AC-3, E-AC-3 and AAC/HE-AAC. Integrated Jünger Level Magic enables compliance with the U.S. CALM Act by automatically eliminating audio level changes both within a channel and when switching from one channel to another.
