Abstract

The preferred embodiments of the present invention relates to the preparation and delivery of media content from a source to a remote device, and the use of the remote device to re-construct, format, composite, convert and/or otherwise pre-process the content into a suitable form for presentation/playback. In particular it relates to audio and/or visual content that may be delivered in a piecemeal, disjoint, complex and/or highly compressed form to a remote mobile device such as a mobile phone where such a device may not have the capability to adequately present the content in its delivered form without further pre-processing due to insufficient on-board processing power or format incompatibilities. The present invention also allows for media content to be reconstituted for presentation in a variety of ways without the need to re-deliver the entire content each time.

receiving compressed media data file;

extrapolating, from said compressed media data file, compression information, said compression information indicating a compression method by which the media data file was compressed;

determining a decompression method in accordance with the compression information;

before presenting the media data file on the remote device, decompressing the compressed media data file in accordance with the determined decompression method; and

presenting the decompressed media data file on the remote device.

6. The method of claim 5, wherein said media data file is one of a video file, computer generated graphics file, and audio file.

7. A method for presenting a composite media data file on a mobile device, said method comprising the steps of:

receiving a plurality of media data files;

extrapolating, from each of said plurality of media data files, corresponding compression information indicating a method by which each of said plurality of media data files is compressed;

using the extrapolated compression information for each media data file to determine a decompression method for each media data file;

decompressing each of said plurality of media data files;

selectively combining the decompressed media data files into a composite media data file; and

presenting on the mobile device the composite media data file.

8. The method of claim 7, wherein each media data file is one of a video data file, audio data file, graphics file, and text file.

9. The method of claim 7, further comprising the steps of:

disassembling the composite media data file into a plurality of disassembled media data files;

selectively combine a subset of said plurality of disassembled media data files into a second composite media file; and

presenting said second composite media file.

10. A remote device for receiving and presenting media data files, said remote device comprising:

a receiver for receiving a plurality of media data files;

a programmed processor for extrapolating, from each of said plurality of media data files, corresponding compression information indicating a method by which each of said plurality of media data files is compressed, and using the extrapolated compression information for each media data file to determine a decompression method for each media data file;

a decompressor for decompressing each of said plurality of media data files;

an assembler for selectively combine the decompressed media data files into a composite media data file; and

a multimedia presenting device for presenting the composite media data file.

11. A remote device for receiving and presenting media data files, said remote device comprising:

a receiver for receiving a plurality of media data files;

a programmed processor for extrapolating, from each of said plurality of media data files, corresponding compression information indicating a method by which each of said plurality of media data files is compressed, and using the extrapolated compression information for each media data file to determine a decompression method for each media data file;
