Abstract:
1. A method comprising: receiving a plurality of streams of hierarchical data from at least one data source into at least one buffer of a router, the stream of hierarchical data comprising sequential data in which future data depends on previous data; receiving a request from a device to transmit one of the streams of hierarchical data to the device; in response to the request, selecting one type of initial hierarchical data from a group comprising intermediate join data, buffered data, delayed data, and current data stored in the at least one buffer of the router as initial hierarchical data; providing the initial hierarchical data from the at least one buffer of the router to the device, the initial hierarchical data including an access point to enable decoding of hierarchical data, the access point decodable without reference to other hierarchical data; and after providing the initial hierarchical data, providing additional hierarchical data from the at least one buffer of the router to the device.
