BSI Successfully Tests New 4K Wireless Transmission System on Aviva Premiership Rugby

Broadcast Sports International (BSI) has completed the first real-world test of their new 4K mobile wireless transmission system for OB production. Using its Real freedom product line as the basis for the transmission system, BSI has incorporated a low delay H.265 encoder capable of transmitting high quality 4k content from a quad-3G SDI source.  Currently a first generation system, the system performed beyond expectations when deployed in a side by side test with HD wireless systems at the Aviva Premiership Rugby event in Northampton, UK earlier this month. 

The images captured showed no perceptible artifacts when displayed on a 27” 4K monitor and the proven RF performance of the Real Freedom system allowed for seamless coverage around the pitch. The throughput of the encoding was purposefully limited to 15/mbps in order to evaluate the effectiveness of encoding at a rate that was easily achievable in an 8 MHz wide carrier. While the system is capable of much higher throughput with the use of BSI’s dual pedestal transmission capability, this outing was intended to evaluate quality and robustness in a real world broadcast environment.

BSI’s engineering team is continuing to make further improvements to latency, power consumption, and to incorporate all thefeatures that are expected of a BSI design. The company’s integrated camera control system has already been upgraded to incorporate 4K controls for Sony cameras that supply native quad-3G outputs with support for other manufacturers underway.
