Behind the Patents: Traffic Independent Synchronization (TIS)


Blackfire Research boasts 14 U.S. patents, all of which are used to create flawless solutions for better, wireless home entertainment. In Blackbook, we’ll take a closer look at some of the patented technology behind Blackfire’s brand. Let’s start the series off with “Traffic Independent Synchronization,” or, TIS for short, which produces better management and precision operation when it comes to synchronizing wireless speakers.


TIS is our patented synchronization technology that can be used to sync any number of wireless devices, from multi speaker 5.1 audio systems, stereo systems, even your entire home theater. One problem facing a standard method of synchronization is that its performance is tied to the performance of the network environment. At home, if you regularly experience spotty Wi-Fi, you won’t have much luck getting those expensive wireless speakers you got for Christmas to sync properly. In fact, there will most likely be a noticeable playback lag from one speaker to the next. TIS ensures that the synchronization of any device is not dependent on how well your router works. So, even in poor Wi-Fi conditions, the synchronization of your speakers won’t be impacted. Sounds good, doesn’t it?


Another problem with a standard method of synchronization is that the more devices you have on a given network (and therefore, the more congested the network is) the slower it runs, which could produce an extended lag between multiple speakers and between your TV and the speakers – even total dropouts. Unlike our competitors, Blackfire’s patented TIS technology always maintains latency between audio and video pairings and among the speakers themselves. With TIS, the sync of the speakers in your wireless home entertainment system will remain undisturbed by heavy network traffic, so you’ll never miss a single moment of your favorite song or movie again.


Finally, Blackfire’s patented TIS software results in superior synchronization at range compared to competing technologies. That means, products with Blackfire’s TIS software will perform better farther away from your Wi-Fi hotspot or router than other brands.

Want to hear the difference for yourself? TIS works with many different hardware platforms, and currently, can be found in all Harman Omni products. Happy listening!
