Abstract
In a data communication system such as a high capacity DBS system, dynamic mapping of broadcast resources is provided to exploit occasional redundancy in the program content of two or more input data streams, freeing at least one broadcast resource to carry alternate bitstreams, such as additional programs or existing programs at higher quality. Transmission maps defining the correspondence between input data streams and broadcast resources, and reception maps defining the correspondence between broadcast resources and output data streams, are updated as needed to dynamically modify broadcast resource mapping to increase effective utilization of available bandwidth. Beneficial n:n-y:m mapping in a high capacity consumer DBS entertainment system is provided. Apparatus and methods for efficiently generating, maintaining and updating allocation maps with reduced overhead requirements, are disclosed.

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.
