HEVC Statmux

Statistical Multiplex of HEVC Live Encoders

Fraunhofer HHI has developed a highly efficient live Statistical Multiplexer (Statmux) for optimized bitrate allocation between multiple Fraunhofer HHI HEVC live encoders. The bitrate of each encoder is adjusted in a closed-loop Statmux to optimize the bandwidth usage and improve the video quality.


  • Most efficient usage of available throughput
  • Content-aware channel bitrate adjustment
  • Scales over multiple servers with increasing number of channels
  • Joint optimization of HD and UHD channels
  • Special operating mode of the HHI HEVC Live Encoder SDK
  • One HHI HEVC Live Encoder instance per channel
