Harmonic's digital video headend solutions have been deployed by On Digital Media (ODM) to power its new TopTV pay TV service in South Africa. The headend system includes Harmonic’s Electra 5400 MPEG-4 AVC (H.264) multi-channel encoders and the ProStream 1000 stream processing platform with DiviTrackIP statistical multiplexing.
This new solution was implemented for ODM in under two months by African Union Communications, a leading systems integrator and Harmonic reseller in South Africa.
TopTV has a total of 52 channels of which 14 are contributed from South Africa. Using the Harmonic headend system these 14 channels are sent over IP via SEACOM's undersea fiber optic cable and are received at TopTV's teleport in Germany where they are multiplexed with the remaining channels on another Harmonic headend system. The complete 52-channel line-up is then uplinked to the SES World Skies Sirius 4 Ku-band satellite over Africa and delivered to the consumer via a compact set-top box.
