Harmonic Adds Forward Error Correction to IP Streaming Platform

Harmonic has enhanced its ProStream 1000 stream processing platform with forward error correction (FEC) support.

Harmonic's FEC engine supports ProMPEG FEC COP3 transmission and reception of up to 128 services in a one rack-unit (RU) platform, helping to minimize problems such as packet drops and reordering.

The ProStream is a multi-functional stream processing system capable of being configured to support FEC, multiplexing, "DiviTrackIP" statistical multiplexing, "ProCipher" scrambling and descrambling, "Mentor" re-encoding and single frequency network (SFN) transmission over IP.

The ProStream 1000 with FEC support is used in conjunction with Harmonic's family of DiviCom high definition (HD) and standard definition (SD) MPEG-4 AVC (H.264) and MPEG-2 encoders. The compact and scalable 1-RU ProStream can transmit and receive up to 128 single program transport streams (SPTS) or eight multiple program transport streams (MPTS) with forward error correction.
