Interactive data transfer system for electronic learning, comprises interactive information distribution device for communicating with license data memory via content request handler

摘要

The system comprises a user sub-system (10), a memory (122) for license data, and a content storage device (120). The sub-system comprises a connection for user computers, an interactive information distribution device (102), and a content request handler (CRH). The distribution device starts an interactive session with a user computer (100) and stores local progress registration information for use after the session, depending on messages from the user computer. The distribution device also generates a command for retrieving a content item in response to a further message from the user computer during the session. The distribution device comprises a content adapter (104) used to send a combination of the information from the command with identification information for a user associated with the session to the content request handler. The content request handler responds by asking for license data for the content item and user from the license data information memory, and if the license data allows it, loading the content item from the content item storage device and sending it to the user computer via the distribution device.
