Harmonic Unveils Single Illumination System For Satellite Distribution

Harmonic has introduced a new Single Illumination System (SIS) offering to ensure greater interoperability and cost savings for broadcast operators with digital terrestrial television (DTT) and direct-to-home (DTH) services.
Based on the DVB-SIS standard, Harmonic's new offering reduces multiplex distribution costs by about 50% compared with the double satellite illumination method and enables broadcast operators to deliver regional channels with greater efficiency.
Harmonic’s DVB-SIS offering is available as a software license on the ProStream X Video Stream Processor and the XOS Edge Advanced Media Processor. Migrating to DVB-SIS is as simple as activating the software at the headend and transmitter site. With Harmonic’s DVB-SIS offering, operators can individually tune the bandwidth of regional channels, improving distribution efficiency and flexibility.
