Terrestrial Broadcast

The World of Broadcast is Changing Rapidly

From MPEG-2 to AVC to HEVC, new formats and delivery methods continue to evolve. To succeed, today’s broadcasters require the ability to deliver superior video for multiple services over constrained networks with bullet-proof reliability — whether supporting ATSC, DVB-T or ISDB-T.

Highlighted Applications

ATSC 3.0

The next-generation ATSC 3.0 standard will usher in a range of new capabilities for broadcasters that leverage advanced modulation technology, IP delivery as the transport mechanism and HEVC compression to provide the most robust television service possible. UHD with high dynamic range (HDR) and wide color gamut, better sound and OTT multiscreen delivery all figure into this new paradigm. No company is better able to help you transition to ATSC 3.0 than Harmonic. Read more on our ATSC 3.0 solution.


The DVB-T switch-off is scheduled for 2020. Transitioning to its replacement, DVB-T2 will provide broadcasters with a wide range of benefits, including improved spectrum efficiency through the use of HEVC compression, HD-to-UHD service enhancement, superior video and audio quality, and DVB subtitling. Harmonic offers a complete range of equipment to help you migrate to DVB-T2 and take full advantage of everything the new standard has to offer. Harmonic also offers a flexible solution for regionalization of DVB-T2 multiplexes: SingleFeed. SingleFeed enables headend operators to preserve resources and bandwidth for distributing bouquets of services to both DTH satellite and terrestrial transmitters.
