a presentation layer preferences database configured to maintain multimedia object presentation preferences;

a presentation layer adaptor configured to query said presentation layer preferences database to determine possible preferences for presenting any of said multimedia objects on said recipient device, and adapt said presentation layer in accordance with said preferences; and

a message encoder configured to package said adapted multimedia objects, presentation layer information, and message headers into an adapted message for delivery to said recipient device.

2. A system according to claim 1 wherein any of said presentation preferences are set at a system level for providing a uniform, system-wide presentation standard for a plurality of subscribers across a plurality of service providers.

3. A system according to claim 1 wherein any of said presentation preferences are set at a subscriber level.

4. A system according to claim 1 wherein said multimedia adaptor is configured to derive the intended recipient'"'"'s subscriber-specific ID for accessing specific subscriber-level presentation preferences.

5. A system according to claim 1 wherein said device capabilities database maintains presentation layer support capabilities for said multimedia devices.

6. A presentation layer adaptor comprising:

a) a presentation layer adder/remover configured to receive multimedia message input and either of a1) remove a presentation layer from a multimedia message and a2) insert a presentation layer into a multimedia message in accordance with the capabilities of a recipient device to which said message is directed;

b) a device capabilities database configured to maintain information about the presentation layer support capabilities of a plurality of multimedia devices;

c) an unconditional adaptations module configured to perform any of the following presentation layer adaptations;

c1) change the available presentation resolution in accordance with the resolution supported by said recipient device as indicated in said device capabilities database;

c2) delete references to any media objects in said message that were deleted during media adaptation;

c3) add references to any media objects in said message that were added during media adaptation or when said presentation layer information was added to said message;

d) a presentation layer preferences database configured to maintain presentation preferences;

e) an adaptation decisions module configured to query said device capabilities database and said presentation layer preferences database and obtain characteristics of said media objects to determine which adaptations may be applied to said message presentation layer for said incoming message and said recipient device;

f) an adaptation execution module configured to implement all of said adaptations determined for said message'"'"'s presentation layer; and

g) a presentation layer encoder configured to encode said presentation layer information for incorporation into an adapted message which includes both adapted multimedia and said presentation layer information.

7. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to perform a portrait media layout change by changing the layout of each object on a display screen and the relation between layout size with vertical portrait alignment.

8. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to perform a landscape media layout change by changing the layout of each object on a display screen and the relation between layout size with landscape portrait alignment.

9. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to dividing any of said media objects that are displayed in a single slide into two or more slides.

10. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to perform timing changes in accordance with media characteristics and presentation preferences.

11. A presentation layer adaptor according to claim 6 and further comprising a presentation layer parser configured to receive and parse presentation layer information associated with said multimedia message input.

12. A presentation layer adaptor according to claim 6 and further comprising a slide categorization module configured to categorize each slide defined in said presentation layer to a type, wherein said presentation layer preferences database is configured to maintain presentation preferences for each of said slide types.

13. A presentation layer adaptor according to claim 6 wherein said presentation layer adder/remover is configured to add said presentation layer from a predefined template if no presentation layer is present in said source message.

14. A presentation layer adaptor according to claim 13 wherein said template does not include any specific references to media objects.

15. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to determine adaptations to said presentation layer in accordance with a change to any of said media objects in said message.

16. A presentation layer adaptor according to claim 6 wherein said adaptation decisions module is configured to determine adaptations to said presentation layer in accordance with recipient device capabilities as indicated by said device capabilities database.

17. A computer-implemented method for multimedia message adaptation with presentation layer adaptation, the method comprising:

stripping any message headers, multimedia object attachments, and presentation layer information from a message received from a sending device and intended for a recipient device;

identifying the intended recipient device of said message;

determining the device capabilities of said recipient device to determine possible media characteristics for presenting any of said multimedia objects on said recipient device;

adapting any of said multimedia objects for presentation on said recipient device in accordance with said characteristics;

determining possible presentation layer preferences for presenting any of said multimedia objects on said recipient device;

adapting said presentation layer in accordance with said preferences; and

packaging said adapted multimedia objects, presentation layer information, and message headers into an adapted message for delivery to said recipient device.

18. A method according to claim 17 wherein said adapting presentation layer step comprises adapting to a system-level preference to provide a uniform, system-wide presentation standard for a plurality of subscribers across a plurality of service providers.

19. A method according to claim 17 wherein said adapting presentation layer step comprises adapting to a subscriber-level preference.

20. A method according to claim 17 and further comprising deriving the intended recipient'"'"'s subscriber-specific ID for accessing specific subscriber-level presentation preferences.

21. A method for adapting the presentation layer of a multimedia message, the method comprising:
