Abstract:
1. A method for transferring source data from a server to a client, the method comprising the steps of; generating, from the source data, transform data comprising spatially related coefficients such that a block of coefficients permit reconstruction of identifiable portions of the source data; partitioning the transform data into a plurality of partitions of coefficients, each partition comprising coefficients for reconstruction of an identifiable portion of the source data; generating, at a client, a request for at least one partition of the coefficients of the source data; transferring, from the client to a server, the request; extracting, at the server, the at least one partition of coefficients set forth in the request; transferring, from the server to the client, the at least one partition of coefficients; and reconstructing the source data at the client from the transform data.
