Abstract

A system for preparing data, operable with a server computer system having a store for a first file comprising data (e.g. audio data) and a plurality of sets of lossy data generated from the data in the first file. The system comprises a requesting component for requesting at least two sets of the plurality of sets of lossy data; a receiving component for receiving the at least two sets; and a combining component for combining the at least two sets in order to generate a second file. The data in the second file is of reduced lossiness with respect to the data in the first file.

Claims

1. A system for preparing data, operable with a server computer system having a store for a first file comprising data and a plurality of sets of lossy data generated from the data in the first file, the system comprising:

a requesting component for requesting at least two sets of the plurality of sets of lossy data;

a first receiving component for receiving the at least two sets; and

a combining component for combining the at least two sets, in order to generate a second file comprising data of reduced lossiness with respect to the data in the first file.

2. A system as claimed in claim 1, further comprising a rendering component for rendering the second file.

3. A system as claimed in claim 1, wherein each set of the plurality of sets of lossy data are combined.

4. A system as claimed in claim 1, wherein the combining component further comprises means for using information associated with the at least two sets, wherein the information represents at least one of:

a number of the at least two sets to be combined and identifiers associated with the at least two sets to be combined.

5. A system as claimed in claim 1, wherein the data in the first file comprises multimedia data.

6. A system as claimed in claim 1, wherein the combining component is invoked according to a proximity value.

7. A system as claimed in claim 1, further comprising:

a server computer system having;

a lossy data generating component for reading the data in the first file and separating the data in the first file into the plurality of sets of lossy data;

a second receiving component for receiving a request for the at least two sets from the system; and

a sending component, in response to receiving the request, for sending the at least two sets to the system.

8. A system as claimed in claim 7, wherein the server computer system further comprises a generating component for generating metadata associated with the plurality of sets of lossy data, the metadata representing at least one of:

a base address, an offset, a spacing between portions of the lossy data.

9. A method of preparing data for use with a server computer system having a store for a first file comprising data and a plurality of sets of lossy data generated from the data in the first file, the method comprising the steps of:

requesting at least two sets of the plurality of sets of lossy data;

receiving the at least two sets; and

combining the at least two sets, in order to generate a second file comprising data of reduced lossiness with respect to the data in the first file.

10. A computer program comprising program code means adapted to perform all the steps of claim 9 when said program is run on a computer.
