SAN JOSE, Calif. — Sept. 6, 2018 — Harmonic (NASDAQ: HLIT) today announced that M6 Group, leading operator of multiple TV channels in France, will upgrade its ingest, playout and storage infrastructure to a media-over-IP solution from Harmonic. Offering support for the SMPTE ST 2110 suite of standards for professional media delivery over IP networks and SMPTE 2022-7 for seamless protection switching, Harmonic's playout and storage solutions will streamline the broadcaster's transition to all-IP video delivery.

"Having relied upon Harmonic's video production and playout solutions for over a decade, we know firsthand the reliability and innovation they provide," said Mathias Bejanin, CTO at M6 Group. "When the infrastructure goes live, we will be leading the market in global deployments of SMPTE ST 2110 and SMPTE 2022-7 protection, setting the benchmark for workflow modernization, efficiency and redundancy."

M6 Group chose Harmonic's Spectrum™ X media servers and MediaGrid shared storage system based on their rock-solid reliability and workflow simplicity. They will use the Spectrum X media servers for content ingest, live switching with graphics, DVE, 24x7 playout and manual review, with manual control supported through Broadteam's Omnium video controller. Harmonic's MediaGrid shared storage system will support M6 Group's real-time editing and playout operations.

"The transition toward an all-IP workflow is rapidly gaining traction in our industry based on the significant workflow efficiencies and cost savings that it provides," said Ian Graham, senior vice president of sales, EMEA and LATAM, at Harmonic. "We're excited to support M6 Group and unleash the full power of IP for playout and storage workflows utilizing the SMPTE ST 2110 and SMPTE 2022-7 standards, which are supported by Spectrum X, the industry's trusted media server."
