Dynamic Stream Balancing (DSB) gets more HiFi through your WiFi

Back in November, we took an in-depth look at Traffic Independent Synchronization (TIS), a Blackfire Research technology which allows precise syncing of your wireless speakers. And last week, we discussed Real-Time Packet Management (RPM), a technology for streaming music to your speakers without excessive buffering. Today, we’re finishing off the series with Dynamic Stream Balancing (DSB).

Dynamic Stream Balancing (DSB) is the way Blackfire makes the best use of the available WiFi bandwidth. If you have a wireless, multi-speaker system that uses conventional WiFi protocols, chances are that some speakers will be more affected than others by interference and heavy network traffic, which causes your music to break up and for speakers to go out of sync.

DSB monitors a special multipoint, real-time feedback signal from each speaker to identify the effect of noise on the audio data stream. By precisely identifying which packets are statistically most likely to be affected, DSB can then use the available WiFi bandwidth to selectively and predictively resend data just to the most vulnerable speaker before interference can cause any audible drop out. So less data is needed in the buffer, which means delays in the audio stream are reduced from 10’s of seconds to 10’s of milliseconds.

This is especially helpful when using a wireless surround sound system to watch video. With DSB, your Blackfire wireless system has minimal lag between the video on your screen and audio through your speakers. HD Audio in up to 24-bit/192kHz Studio Quality and even HD Video can be streamed to any device from any room, losslessly.

DSB, as well as TIS and RPM, is embedded into all Blackfire enabled products. Together, these technologies create FCP: Firecast Protocol – Blackfire’s solution to streaming music and video over your regular WiFi network, flawlessly.

Want to hear the difference for yourself? Firecast is found in all Blackfire enabled products, including The Harman/Kardon Omni Series and Pioneer MRX Series. Happy listening!
