A method for managing bind-render-target commands in a tile-based architecture. In some embodiments, the application allows a user to select media content and creates the journal by populating it with the selected content. Hyperlinks to a second IVR service offered on a web server at a different URL address are embedded and associated with a specific question or statement in a PML-formatted page produced by the first service. An encryption region specifying unit 214 allows a document editor to input data that specifies the region of the encryption target data in the document file displayed on the screen.
