Enables the convergence of real time communications and streaming content


User generated audio and video content is reshaping media viewing and listening habits. The Radisys MediaEngine media server platform enables service providers to optimize media to ensure the best user experience based on the device, network conditions, codec, and service levels. MediaEngine can improve the quality of media in real time or “off-line”, based on whether the content is expected to be streamed or broadcasted. User generated content also requires media adaptation for it to be viewed by users on multiple devices. The economies to perform off-line transcoding and storage may not always make sense and sometimes mandate transcoding on the fly. Radisys Media Server enables both off-line and on-demand transcoding, ensuring the lowest cost approach. MediaEngine can be distributed both in the core of the network and at the edge, adding another dimension to cost efficiency by processing media where it’s most bandwidth efficient and latency optimized.

Key Benefits

  • High scale real time and offline video transcoding and transrating
  • On-the fly audio and video quality enhancements
  • Deployable in the network core or edge
  • Simultaneously processes real time conversational and user generated media for applications that combine both
