    摘要: A method for multicasting Internet Protocol (IP) streaming data to a mobile platform passenger is provided. The method includes receiving data content at a base station network from a content provider. The received data is formatted at the base station into an IP multicast data stream and communicated to a mobile platform communications system onboard a mobile platform. The mobile platform communications system includes a local area network (LAN) used to distribute the IP multicast data stream to at least one mobile platform client interface. The data content of the IP multicast data stream is then displayed on the mobile platform client interface for viewing by a mobile platform passenger. Additionally, the method includes applying forward error correction (FEC) to the IP multicast data stream to correct for data losses, prior to distributing the IP multicast data stream to the mobile platform client interface. The method further includes decoding the FEC encoded IP multicast data stream so that the corrected data content can be interpreted and displayed on the mobile platform client interface.

    摘要: A system and method for analyzing a scenario, such as a communications scenario in which the end-to-end quality of communications between end nodes of a communications link may be affected by various factors and conditions. Such factors and conditions may include performance parameters of the end nodes and intermediate nodes, human operational performance, and external conditions, such as weather. Qualitative and quantitative representations of the end-to-end quality of communications are presented simultaneously and in a time-synchronized manner with displays of the relevant performance parameters, indications of human operational actions, and locations of nodes of the communications link and external conditions.
