Abstract
The present disclosure provides video transmission systems and methods with video data flows transmitted over a Carrier Ethernet Network at Layer 2 with redundancy in order to provide hitless protection switching and uninterrupted video service delivery, such as during periods of asymmetric congestion or hard network failures. In an exemplary embodiment, the video transmission systems and methods provide the redundancy in a manner similar to 1+1 linear protection with hit-less protection switching. In another exemplary embodiment, the video transmission systems and methods provide encapsulated video signals over Ethernet using standardized Carrier Ethernet frames with additional sequencing information. Optionally, the video transmission systems and methods may also include packet-based forward error correction information for additional resiliency. These video transmission systems and methods provide uninterrupted and error-free video during broadcast despite network events such as fiber breaks, equipment failures, congestion, etc.
