Real time IP MPEG-2 or H.264 transport stream redundancy switch with seamless transport layer switching. Includes built in resynchronizer + buffer for 2 streams arriving via different paths. Designed to deliver 1+1 redundancy with 2 parallel input sources and 2 outputs switched in milliseconds via transistors. Will switch the entire MPTS stream at the same time from input 1 to input 2. Switching criteria is programmable and relies on ETRI 290 oriented health indicators.
