Abstract

A system and method designed to optimize the delivery of information on demand via wired or wireless connections. Dynamic information such as weather data can be delivered as compressed text, images, charts, buoy data, radar, GRIB files, and many more formats. Numerous continuously updated products can be delivered to a user of a client application on demand by the push of a button. The user can generate a batch folder having a list of data products to download. The data list in the batch folder can be requested from a server using a single command. The system and method can be configured to immediately connect to a server via a wireless connection or email, including satellite phone and HF/Pactor Radio, and downloads the requested data. After the download the client can be configured to automatically display the requested data.

concatenating the plurality of compressed content files;

transmitting the selected content files from the server to local storage on the user terminal in response to the content request;

automatically disconnecting the communication link between the user terminal and the server upon receipt of all selected content files in the content request; and

retrieving at least a portion of the selected content files from the local storage and displaying content from the content files on the user terminal after the communication link has been disconnected.

11. The method of claim 10, further comprising:

determining a cost associated with the content request by summing a cost associated with each of the plurality of selected content files; and

applying a charge to a user account corresponding to an originator of the content request.

12. The method of claim 11, wherein at least one of the plurality of selected content files is available from a corresponding original content source free of charge.

13. The method of claim 10, further comprising:

receiving an offset value in addition to the content request; and

providing only a portion of the selected content files based on the offset value.

14. The method of claim 10, further comprising:

periodically retrieving each of the content files corresponding to a content library from a corresponding original content source; and

storing the copy of the content file in the data store.

15. The method of claim 10, wherein receiving the content request comprises:
