Maui deploys Harmonic’s systems for network rebuild

The ProStream 1000 technology encapsulates all traffic using forward error correction to provide good service quality

By CBR Staff Writer

Maui, a consortium of six broadcast stations headquartered in Oahu, Hawaii, has deployed Harmonic’s ProStream 1000 stream processing systems and NMX Digital Service Manager for a substantial network rebuild.

According to Harmonic, the upgrade enables the participating broadcast television stations to transmit broadcast digital signals from Oahu to Maui and the Big Island of Hawaii over a fiber-based high-speed data service provided by Time Warner Cable Business Class Services.

Harmonic’s ProStream 1000 is an integral component of Maui’s new video delivery chain. The advanced system converts ATSC-DTV ASI transport streams from each of the Oahu stations into IP signals; facilitates the transport of the IP streams to Maui and Hawaii via the resilient 10Gb fiber oceanic CWDM link; then re-converts the streams to ASI for transmission to subscribers, said Harmonic. The ProStream 1000 technology can encapsulate all traffic using forward error correction to provide good service quality.

Rodney Shimabukuro, lead engineer at Maui, said: Harmonic delivered a superior solution that was quickly implemented, provided several operational and performance advantages, and enabled us to discontinue our Mount Haleakala operations and protect our environment. Maui’s new infrastructure seamlessly supports our current digital transmission requirements and provides a nearly inexhaustible two-way service that can be easily scaled to meet our future needs.
