Abstract
A combined hardware and software solution for real-time seamless switching of media streams using standard Ethernet switches and compliant end-points is disclosed. The combined hardware and software solution includes a FPGA offload module and a process for seamless frame-level switching of media streams in real-time. Specifically, the FPGA offload module and process for seamless frame-level switching of media streams in real-time includes hardware offload at an IP/Ethernet switch port, supporting switch software to enable seamless switching, and supporting endpoint hardware and software to utilize seamless switching, thereby allowing video streams to be switched exactly between frames, and for switching losses to be recovered.
