摘要： A reference time distribution system and method use a data transmission network having a plurality of nodes to distribute the House Sync signal. A network-wide time signal is generated using a reference time generator, and the network-wide time signal is then distributed over the network to the plurality of nodes. At each node, the network-wide time signal is converted to a local synchronization signal for use in performing synchronization of the timing of each node. Either network-inherent timing and/or additional time signaling is used to provide the nodes attached to this network with a network-wide notion of time. The time information is converted locally into synchronization signals or time information as required by a respective application. When data is transported over the network, delay compensation is performed to simultaneously output different data streams that have been synchronously input into the network, regardless of the data path.

摘要： Split IEEE 1394 bridges utilize individual portals or bundles of portals to communicate over a non-full-featured IEEE 1394 network such as a local or wide area network in combination with IEEE 1394 multi-portal bridges. Multi-portal bridges may be formed through the connection of several split bridges each with one or more IEEE 1394 portals over a core net. The core net is invisible to the IEEE 1394 nodes with respect to traffic originating from an IEEE 1394 bus for a destination in an IEEE 1394 bus, and the network elements allow for increased network scalability in both terms of physical size and levels of hierarchy. Useful properties of a core net such as availability of high-performance switches or increased reach are incorporated into an IEEE 1394 network.
