A digital audio playback device (DAPD) includes: 1) an external interface for coupling to a connected processing system that executes a user interface application program that accesses and controls the digital audio playback device via the external interface; 2) a memory coupled to the external interface for storing a reverse DAPD application programming interface (API); and 3) a processor coupled to the memory and the external interface for executing the reverse DAPD API. The reverse DAPD API causes the processor to access and control a user interface operated by the user interface application program displayed on a monitor screen of the connected processing system.

System and method for displaying information on the screen of a user interface device under the control of a digital audio playback device

A method of operating a system including a digital network interconnected intelligent digital devices (IDDS) generating and receiving eXtensible Markup Language (XML) documents containing data and respective Document Type Definitions (DTDs) describing the data content. Preferably, the method includes steps for transmitting a generated XML document from a first IDD to a second IDD, and, when the respective DTD for the generated XML document satisfies a predetermined criteria, operating on the data contained in the XML document at the second IDD. In a first exemplary case, the second IDD maintains a list of trusted DTDs, and the predetermined criteria is equality between the name of the respective DTD and the name of a trusted DTD. Alternatively, the predetermined criteria is satisfied by inclusion of the name of a program residing on the second IDD in the respective DTD. In a second exemplary case, the transmitting step includes transmitting the generated XML document from the first IDD to the second IDD and a third IDD, the operating step includes operating on the data contained in the XML document at the second IDD when the respective DTD for the generated XML document satisfies a first predetermined criteria, and the method further includes the step of operating on the data contained in the XML document at the third IDD when the respective DTD for the generated XML document satisfies a second predetermined criteria. A system composed of IDDs interconnected by an in home digital network (IHDN) or other mechanism, which system can be operated by the method mentioned above, is also described.

This invention facilitates the relocation of a hypertext document and objects referenced by hypertext items. The Universal Resource Locators (URLs) in a hypertext document are identified and assessed. A modifiable URL is a URL that is associated with an object that has been relocated, or with an object that will be relocated when the hypertext document is relocated. Each modifiable URL in the document is modified to reflect the relocation of each object, and each object that has not yet been relocated is relocated. If any relocated object is another hypertext document, this other document is similarly processed to identify and update each modifiable URL, each object requiring relocation is relocated, and each relocated hypertext document is subsequently similarly processed.
