Eutelsat Communications SA, a provider of fixed satellite services, has selected Harmonic's ProStream 1000 with ACE stream processing and transcoding solution to optimize bandwidth allocation for its direct-to-home, or DTH, service in Africa.
Utilizing the ProStream platform, Eutelsat has implemented dual illumination of DVB-S/MPEG-2 and DVB-S2/MPEG-4 video content to increase satellite capacity and its DTH service offerings, as well as deliver superior video quality to subscribers, Harmonic said.
"The main objective of this project was to capitalize on the bandwidth efficiencies offered by MPEG-4 while ensuring there was no discernible difference in service quality for our customers," said Jerome Gressier, head of platforms engineering and operations team, at Eutelsat. "ProStream 1000 with ACE transcoding achieves excellent video quality at exceptionally low bit rates, enabling us to deliver additional channels at a more competitive price."
The ProStream 1000 with ACE solution maximizes Eutelsat's bandwidth efficiency by providing up to 20 HD or 60 SD channels of video and audio transcoding from a single rack unit. The solution also incorporates ASI-to-IP multiplexing and scrambling while integrating with the existing headend, which includes Harmonic ProView 7000 integrated receiver-decoders (IRDs). The ProStream solution offers advanced DiviTrack statistical multiplexing technology to create up to 16 pools of transcoded channels with 64 channels per pool, allowing Eutelsat to deliver the best video quality at the low aggregate bandwidth. Leveraging the bandwidth savings enabled by the ProStream 1000 with ACE solution, Eutelsat can support twice as many channels per satellite transponder, the company added.
The high-density platform lowers capital and operating expenses through reduced rack space and energy consumption, drawing 10 watts per HD channel and less than 3 watts per SD channel. Through its scalable architecture, the ProStream solution provides Eutelsat with the flexibility to support additional channels, as well as value-added services such as multiscreen in the future, the company concluded.
