News, Broadcast Business


Snell has announced that it will debut its Sirius 800 enterprise-class routing switchers at IBC this year. The switches have enhancements including guaranteed co-timing of multi-channel audio on all channels, single reference switching for all formats, numerous control-related updates, and a technology demonstration of a new audio and video fingerprinting solution.

The Sirius 800 system on display will also feature frame synchronisation on the units' Advanced Hybrid Processing (AHP) input and output cards, an option that enables synchronization, clean switching, and independent routing and processing of audio and video signals with no restrictions on signal formats, timing, or number of audio channels.

"The Sirius 800 router with AHP is known for its uniquely robust combination of flexibility and functionality, which together give users complete freedom in configuring signals in and out of the routing switcher," said Alan Smith, product manager at Snell. "At IBC2013 we look forward to demonstrating a variety of new features, capabilities, and configuration options that together yield an even more versatile routing and processing solution."

The unique new audio phasing control ensures constant delay, as well as guaranteed co-timing of multi-channel audio for all "same-format" signals across the whole router. In addition, a single reference for switching all formats simplifies system design and a line synchronization mode allows re-timing and clean switching with minimal delay. Adjustable video and individual audio channel delays allow compensation for contribution channel and audio encoding/decoding delays. The audio and video fingerprinting demonstration is based on the company's Hyperion monitoring and quality control technology that facilitates system-wide transmission-path lip-sync monitoring.

The availability of frame synchronisation on the routing switcher's AHP cards makes it possible for every single input into the Sirius 800 router to have its own synchroniser, along with existing capabilities including track swap, gain, delay, and mixing capability for input-level correction, standard channel setup, Dolby 5.1 surround sound downmix, stereo-to-mono mix, output level adjustment, Dolby E delay compensation, video and audio timing delay correction, and sample rate conversion to house standard.
