[0008] Therefore, when users use PostCard services, if they want to print copyright-protected picture content on postcards, they will not be able to do so because PostCard Server does not have an RO.
Moreover, users may also have such problems when using similar MMS services

[0068] The method of the present invention can be used in combination with the PostCard application of OMA MMS 1.3. At this time, it is necessary to add a DRM Agent on the PostCard server, and regard the PostCard server as user B in the method of the present invention. When used in conjunction with the PostCard application, the MMS containing the DCF sent by user A also includes PostCard content.

[0069] For example, if the content of the DCF is a picture, the PostCard server can obtain the RO and DCF through any of the methods described in the above three embodiments, and decode the picture in the DCF. Then arrange pictures and other parts of MMS according to the rules in the MMS expression part (such as SMIL), such as text information, etc., print out the PostCard, and mail according to the traditional postal method.
