TDF Expands Broadcast Channel Lineup With Harmonic

TDF, a broadcast infrastructure operator in France, modernized its terrestrial broadcast network with Harmonic’s XOS Advanced Media Processor and ProStream X Video Stream Processor.

The media processing solutions increase TDF’s channel capacity while maintaining video quality and bandwidth efficiency across its digital terrestrial television (DTT) network.

“As demand for broadcast services continues to grow, we needed a more efficient way to expand our channel offering without increasing bandwidth allocation,” Nathalie Coupé, TDF senior engineer specialized in audiovisual headend systems design, said. “Harmonic’s XOS media processor allows us to elevate channel capacity while making more efficient use of our available spectrum. Its resilient and flexible architecture provides a strong foundation for the continued evolution of our terrestrial broadcast network.”

TDF distributes audiovisual services for public and private broadcasters across France. Using the new processors, the operator now supports six linear HD channels — BFM TV, CNEWS, CSTAR, NOVO19, T18 and GULLI — within the same multiplex bandwidth that previously carried five. The system uses a dual-site architecture spanning geographically separated headend facilities to ensure service continuity.

The software-based XOS processor uses AI-driven compression and Harmonic’s PURE Compression Engine to deliver video quality at low bitrates. The system supports HEVC encoding and 1080p source processing with HDR Dolby Vision. Additionally, the ProStream X processor provides remote statistical multiplexing, allowing bandwidth sharing across multiple sites.

“Harmonic’s media processing solutions are enabling operators like TDF to maximize the efficiency of terrestrial broadcast networks,” Tony Berthaud, Harmonic senior VP of sales, EMEA and APAC, said. “By using the XOS media processor and our PURE compression technology, TDF can deliver more broadcast channels, optimize bandwidth usage and prepare its infrastructure for future broadcast innovations.”

Video delivery solutions provider Harmonic will showcase its media processing technology at the NAB Show in Las Vegas, April 18-22, in Booth W2831.
