Abstract
The efficiency of real-time distribution of multimedia content over a heterogeneous network is optimized by locally, rather than centrally, adapting the content to conform to the capabilities limitations of the network. Multimedia content travels from a central location along the network backbone. When received by each of a system of dispersed media servers, that media server adapts the content by compensating for any QoS limitations of the downstream network segments. For example, the backbone of the communications network may consist of a satellite uplink. The dispersed media servers receive and replicate the content as required for distribution to unicast segments downstream rather than doing so at the source of the content, and thus multiple streams of identical content need not be carried on the backbone. Each dispersed server is programmed to optimize the transmission to conform to the transmission parameters of each adjacent and downstream segment of the network.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
