摘要： The present invention relates to systems, methods and nodes for enabling synchronization between a plurality of nodes in a network, by comparing the times of the GPS clocks of the plurality of nodes to determine accurate clocks being within a tolerance of each other, adjusting priority, and, if the priority of a local clock of a node is low, selecting a remote GPS clock to be used as a timing reference of the GPS clock of the node.

摘要： There is provided a method in a remote media production system in an IP network, in which media production is performed at a stadium or the like, and the produced media content is transferred to a home studio for final production. The media content is transported in individual data streams over a network. In a receiving node R an aggregate of individual delays for the transferred data streams is monitored and form basis for determining at least one network delay correction factor or at least one common network offset for the individual data streams. The method further comprises time adjusting data transmitted over the network with the common network offset.

摘要： There is provided a method in a communication network system 100 of e.g. IP type for live distribution of media content capable of node-to-node time-transfer between nodes in the network system. The media content is sent as a data stream DSx via respective communication links over a network 200. The method comprises transferring local clock signal between nodes and based on received local clock signals determining a unidirectional delay between the nodes. The traffic between the nodes is then based on the determined unidirectional delay.
