Abstract
A method and system for transferring data files from a sever entity, such as a server computer, to a client entity, such as a client process running on a remote client computer. The data files are stored in a frequency domain form by the server entity. The client entity can specify certain characteristics for the transfer that may be represented as one or more parameters. Parameters may include a compression ratio and certain data enhancements. Default or computed parameters may be used by the server entity when no client-specified parameters are available. Upon receiving a request for a data file, the server entity retrieves the frequency domain form of the data file, quantizes frequency domain coefficients included in the frequency domain form of the data file according to the parameters, compresses the quantized frequency domain coefficients into a compressed data file, and transfers the compressed data file to the client entity.
