Electra X Features

Video Compression Excellence

Delivering significantly improved efficiency and simplified upgradeability over competing encoder technologies, the Harmonic PURE Compression Engine enables true codec independence. MPEG-2, MPEG-4 AVC and HEVC Main 10 transport streams are supported, as are the most common SD and HD content formats for broadcast, cable, satellite, IPTV and OTT delivery.


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

High-Quality Graphics and Branding

Drawing upon the advanced functionality of the Harmonic Spectrum ChannelPort™ integrated channel playout system, dynamic text, regulatory and station logos, and rich branding elements are easily added to video channels. Up to eight graphics layers are supported, and graphics elements can be shared across all distribution channels.


Statmux Over IP

Electra X2 and X3 processors maximize the efficiency and flexibility of statistical multiplexing through tight integration with the Harmonic ProStream® product line and DiviTrackIP™ statmux technology.

SD-to-HD Up-Conversion

Featuring integrated broadcast-quality up-conversion, Electra X2 media processors are ideally suited for applications such as HD simulcast of an existing SD channel lineup.

Audio Processing

Electra X2 and X3 support 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.
