Abstract

A wireless mobile device has limited memory and operates on a low-bandwidth network. Web site content comprising images, audio, video, or other data formats may not be supported by the device. If it is supported, the content must be compressed (reduced in size) when sent to the device so that it can consume a minimum amount of memory. Although a page can be downloaded in a form that can be rendered on the device, some of the original content cannot be retrieved, saved, and manipulated. In order for the user to access the content in its original form, the user must re-visit the same site on their computer (PC). It is inconvenient for the user to have to remember a URL that was previously visited, and view the same page twice, or the content may no longer be accessible from the original link, in which case the link itself is insufficient. It is not possible for the user to request that the content in its original form be saved on the server for later retrieval on a PC, in the case where the data cannot be saved on the device or can only be saved in a reduced form. We propose a system that allows content on a site visited using the device browser to be saved in a cache on the server (before it is forwarded to the device in a compressed form). The user can access the uncompressed version of the contents that were downloaded by transferring the contents of the server cache to a PC using a file-transfer protocol. For example, the user may wish to manipulate a document that is available for download from a site, but it cannot be viewed or saved on the device in its native format. The user will have the option instead of saving the content (accessible from a link) to the server cache, and then transferring it to a PC. The structure of the file system containing the compressed data on the device (content store) can be reflected on the server cache, and subsequently on the PC. Thus, the organization of the data, in terms of a folder hierarchy, is retained so that data can more easily be found once downloaded to the PC. Alternatively, the user can specify a location on a PC accessible through the network to which the cached data should be automatically sent and saved, to reduce the amount of data stored on the server. The user will also be able to transfer any content retrieved from a web site on a PC to the server cache, if the format is supported by the server's data compressor. For example, the user could upload a full version of an image to the server, which would then automatically scale it down and compress it, and send it to the device for storage. This system allows for web content retrieved by the device to be synchronized with the PC, which contains more space, greater bandwidth, and greater rendering ability for manipulating data in its original form. When the user accesses web site data on a device, ownership of the original data is retained.
