Abstract
Methods and systems for transmitting data are presented. Data received from at least one data source is retained in at least one buffer. In one example, initial hierarchical data may be provided from the at least one buffer to a device, followed by additional hierarchical data. In one example, the data is received into the at least one buffer via a multicast connection, and the data is provided to the device via a point-to-point connection.
Claims26
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, providing 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.

A method, comprising:
- receiving a plurality of streams of data from at least one data source into at least one buffer of a router via multicast, each of the plurality of streams of data being associated with a unique data rate;
- receiving a request from a device to transmit data to the device;
- in response to the request, transmitting data from one of the plurality of streams of data from the at least one buffer of the router to the device via a point-to-point connection at the data rate associated with the one of the plurality of streams of data.
An apparatus, comprising:
- a multicast communication interface to receive a plurality of streams of data, each of the plurality of streams of data being associated with a unique data rate;
- at least one buffer to store the received plurality of streams of data;
- a point-to-point communication interface to receive a request from a device to transmit data to the device, and to transmit data from one of the plurality of streams of data from the at least one buffer to the device in response to the request;
- and
- control logic to process the request to select the one of the plurality of streams of data.
