Harmonic’s Statmux Encoding Reclaims Satellite Bandwidth

Greece’s pay TV DTH platform chooses Harmonic Electra encoding with statmux.

Forthnet owns Nova, the largest pay-TV satellite platform in Greece. Forthnet has chosen an upper echelon Harmonic.  compression solution with video analytics for direct-to-home (DTH) SD/HD TV service. The solution was integrated and installed by Harmonic's local channel partner and system integrator OmniWave. Using Harmonic's scalable video infrastructure, Forthnet's Nova successfully increased bandwidth efficiency and improved video quality while lowering operational expenses.

Nova relies on a mix of MPEG-2, MPEG-4 and DVB-S2 technologies. Harmonic’s analytical compression gives Nova an edge in the home satellite market. Viewers can appreciate the quality difference.

Nova uses Harmonic's Electra encoders for high-quality, low-bandwidth MPEG-2 and MPEG-4 encoding of SD and HD video content for live and VOD programs. The high-performance encoders increase Nova's channel count per satellite transponder, enabling Nova to create bandwidth that can be used to expand its service offerings. The Electra encoders are integrated with Harmonic's ProStream stream processors for multiplexing, scrambling, and statistical multiplexing of MPEG-2 and MPEG-4 services in multiple streams.

With ProStream statistical multiplexing, Nova can support up to 64 services per statistically multiplexed pool, 16 pools per platform, and three pools within a single transport stream.The ProStream platform is based on a highly robust, extensible, and scalable design that lowers Nova's operating expenses through reduced rack space and power requirements.

Nova deployed Harmonic's Iris advanced video analytics software suite to allow simultaneous monitoring and analysis of up to 250 video services. After collecting data from the Electra encoders in Nova's headend, Iris presents the operator with a comprehensive set of user-friendly charts, reports, and dashboards. With these resources, Nova can optimally balance its DTH channels across statmux pools to optimize bandwidth use and ensure high video quality, ultimately increasing viewer satisfaction.
