Abstract: Multicast transmissions are efficient but do not allow for individual acknowledgement that the data was received by each receiver. This is not acceptable for isochronous systems that require specific levels of QoS for each device. A multimedia communications protocol is provided that uses a novel multi-destination burst transmission protocol in multimedia isochronous systems. The transmitter establishes a bi-directional burst mode for multicasting data to multiple devices and receiving Reverse Start of Frame (RSOF) delimiters from each multicast-destination receiver in response to multiple SOF delimiters, thus providing protocol-efficient multi-destination acknowledgements.

Abstract: A powerline communication system includes a plurality of rail segments. Each of the rail segments is electrically isolated from other rail segments, and each receives power from a rail segment power supply. At least one cart operates on the rail segments. The cart has a powerline communications controller. Each rail segment has a current state defined by how many and which carts are operating on the rail segment. A central coordinator is coupled to each rail segment and configured to execute a channel estimation using a sounding protocol on its rail segment. The central coordinators store tone maps associated with the possible states of its rail segment, and possibly its adjacent rail segment. A main controller communicates with each central coordinator to direct the state and future state of its segment so that tone maps and network keys can be managed by the CCo in advance of an imminent state change.
