Designed for broadcasters, webcasters, and content providers, the IPGuard is a seamless IP and MPEG-2 TS transport layer switching device that can convey MPEG-2 or MPEG-4/H.264 in SD or HD content. It delivers 1+1 redundancy with two parallel IP input sources and two mirrored IP outputs. When the system detects a failure on one input – such as no IP stream or MPEG-2 or H.264 transport stream failure – it automatically switches over to the other valid input to provide continual output.
The IPGuard offers a bypass mechanism via solid state relays that creates 100% service availability in case of power outage. It is designed to provide an automatic 1+1 redundancy of network equipment that delivers services over IP – such as encoders, multiplexers, gateways, ASI to IP adapters, etc. Additionally, the IPGuard can also be operated to re-synchronize and re-align the same MPEG-2 stream that is carried over redundant IP-based networks. The latter introducing different network propagation delay, the IPGuard is able to re-align both IP streams to provide a seamless change-over between redundant IP streams.
