ProStream X - The Heart of the Headend

The ProStream X runs on a COTS Intel Server (1-RU) and provides in
combination with the Harmonic Electra X2 an advanced solution for
encoding and distributing of 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.

SD, HD and UHD formats, and MPEG-2, MPEG-4 AVC and HEVC codecs are all supported on ProStream X.
