Cobalt Digital Enhances Loudness Processing on Fusion3G Series

Cobalt Digital is adding Dolby Transcoding and EAS Audio Ducking on its Fusion3G series for openGear. The enhancements to the company’s loudness-processing solutions are being demonstrated at the NAB Show in Booth N2512.

Cobalt’s Fusion3G comprises multifunctional, multifeatured cards that offer solutions to all of today’s signal-processing challenges: loudness processing, audio-loudness metering, Dolby encode and decode, color correction, fiber transmit and receive, and up/down/crossconversion. The range supports openGear, an architecture platform that handles 3G/HD/SD video-processing cards and audio-processing cards from multiple manufacturers in the same frame.

Starting at the NAB Show, Dolby Transcoding is available on all Fusion3G cards. The enhancement will allow a Dolby E stream to be decoded to baseband (and channel-swapped or optionally loudness-processed) and then re-encoded into Dolby Digital or Digital Plus — all on the same card.

EAS Audio Ducking is also available on all Fusion3G cards via input mixing that allows setup of ducked mixing 5.1 or stereo program audio and EAS audio. A custom mix can be saved on the card and then recalled using the card’s GPI input. When a GPI trigger occurs, the card goes to the ducked mix; when the trigger clears, normal routing is restored. Clean, glitch-free switching in and out of EAS is performed, with response time under 1 second.
