The Harmonic PURE Compression Engine utilizes Harmonic’s market-leading experience in video compression algorithms and multi-pass encoding technologies to provide superior video quality at the lowest possible bitrates. Delivering significantly improved efficiency and simplified upgradeability over hardware-based encoders, the Harmonic PURE Compression Engine supports MPEG-2, MPEG-4 AVC and HEVC codecs, as well as SD, HD and Ultra HD content formats for broadcast, cable, satellite and IPTV delivery — including constant, variable and adaptive bitrate streaming.
Advanced noise-reduction capabilities include Harmonic’s signature motion-compensated temporal filtering (MCTF) to enhance the appearance of incoming material. Electra XVM also supports powerful deinterlacing to cleanly deliver progressive formats.
High-Quality Graphics and Branding
Electra XVM possesses a unique set of capabilities to bring graphics and branding into content distribution and service delivery. Advanced capabilities, including up to eight layers of graphics, DVE squeezeback with dynamic text insertion, full slate insertion, and independent branding on each channel, enable the creation of sophisticated on-air looks — and add ability to separately monetize second screens.
Statmux Over IP
Electra XVM maximizes the efficiency and flexibility of statistical multiplexing through tight integration with the Harmonic DiviTrackIP™ technology. Applicable for either LAN or distributed WAN environments, DiviTrackIP can support up to 300 ms of WAN round-trip delay, auto-adjust to IP network variations, and form MPEG transport streams with up to 64 channels per pool.
Based on the Harmonic VOS platform and architecture, which runs in OpenStack or VMware vSphere virtual machine environments on approved blade servers, Electra XVM provides hardware transparency and maximum operational flexibility. Virtual machine instances of Electra XVM can be turned up or down dynamically according to demand, and leverage data center MIPS capacity according to the mix of tasks performed. This flexibility is delivered with absolutely no compromise on video quality or functionality.
