Radisys recently announced the addition of two new products to its MediaEngine portfolio - MediaEngine Transcode Resource Function (TRF) products. Radisys said that the product has been deployed by leading communications service providers in North America and Asia.
TRF allow communications service providers to deploy transcoding as an adjunct function which scales independently from, and complements existing legacy network elements such as session border controllers (SBCs) and media gateways.
By decoupling transcoding from legacy network elements, communications service providers can reduce the number of transcoding nodes in their network and eliminate the need for expensive forklift upgrades typical when adding HD transcoding capabilities to today’s SBCs and media gateways, said the company.
As service providers accelerate their deployments of VoLTE, VoWiFi and WebRTC interactive services, the need for transcoding is more important than ever. These new services have introduced complex high-definition audio and advanced video codecs into the network, leading to the need for more real-time transcoding and transrating to support service interworking and interoperability between legacy and modern devices and networks. Traditionally, media gateways and SBCs have performed network transcoding functions, but few are designed for today’s complex codecs.
