Abstract: A content delivery system, such as a Just in Time Training (JITT) system which allows the broadcast of multimedia messages to recipients or users. The JITT system identifies the multimedia capabilities as well as the capabilities of the service provider and recipient device for each user and uses this profile information to determine an appropriate messaging format to use to send the message to each user. User involvement is used to determine the functionality and content type delivery for each user mobile device. This profiling may be performed in any of a number of different ways, including smart echo, caller-ID initiated (CIDI) and SMS initiated (SMSI) profiling. In smart echo profiling, the user sends the JITT system a multimedia sample from the mobile device, and the JITT system then sends messages and content to the mobile devise using the same format.
