Abstract: The invention provides a method and system for presenting information in a web document using a program applet to restrict further copying or redistribution. The web document includes a first region in which a graphical element or other information is displayed, and a second region covering the first region in which a program applet is invoked by a server for the web document. The program applet is dynamically created upon access, and assigned a serial number. The program applet contacts the server for permission to display the graphical element or other information; thus, the server can control, by granting or denying permission, when and if the program applet displays the graphical or other information.

Abstract: The invention provides a method and system for entry and editing of multimedia objects for communication and presentation, associating multimedia objects with received sequences of keystroke or mouse action abbreviations. When an abbreviation is detected, the abbreviation is replaced with the associated multimedia object. Each multimedia object has editable properties, and each set of multimedia objects can be collected into an ensemble, which itself can have editable properties. One such ensemble property is a “theme,” which presents a variant of each multimedia object consistent with the theme.

Abstract: A method and system are described for providing features for internet access at an internet appliance which go beyond the resource limitations of the internet appliance. Such features may be implemented on the server, and coupled to the internet appliance for display, responsive to the ability of the internet appliance to provide those features. (1) The internet appliance and the server adapt to communication link limitations by dynamically adjusting picture quality or size for graphics to be displayed. (2) The internet appliance and the server adapt to memory and processor limitations by dynamically running applets at the server and intercepting display functions of applets for display at the internet appliance. (3) The internet appliance and the server adapt to memory and processor limitations by dynamically running editing programs or web pages at the server and by dynamically adjusting picture quality or size for graphics to be displayed.

Abstract: Preloading of web pages is described. In an implementation, an apparatus comprises a processor and storage. The storage includes program instructions that are executable by the processor to load a first web page in response to a selection by an operator and identify a link in the first web page pointing to a second web page. The program instructions are further executable to automatically preload the second web page based on the identified link, the second web page preloaded for later presentation.

Abstract: The invention provides a method and system for formatting electronic mail for transmission, in which electronic mail messages include the operational results of one or more applets. An electronic mail client creates an electronic mail message using one or more applets, each of which may operate to actively receive, transform, and display information to be presented with the electronic mail message. At or near a time when the electronic mail message is formatted for transmission, editable program code for the applets is removed, and any dynamic links between the applets are broken. The electronic mail message made available to the receiver can thus include active elements, but any applets which are received are not editable by the receiver.

Abstract: An improved technique for mixing picture signals directed at a monitor screen. Two analog video signals (such as an analog VGA input and an analog RGB signal produced in response to a stored digital still or moving image) may be multiplexed in analog form. An analog chromakey mixer detects a background color in the first video signal (such as the analog VGA input), and replaces the portion of that first video signal with the second video signal. The time delays of the first video signal and the second video signal may be adjusted so that they reach the monitor screen (by means of an a multiplexer output) at the same time. An alignment detector may attempt to align two known signals (such as a VGA sync signal and a signal generated for this purpose), and may adjust a set of time delays in the analog chromakey mixer until the time difference between the first and second video signals falls below a threshold.

Abstract: The invention provides a method and system for dynamic preloading of web pages. In a system having a page server for transmitting pages upon request and a page client (or “web browser”) for requesting pages and presenting those pages to an operator, the page client dynamically identifies links subsequent to the loaded page and preloads pages identified by those links for subsequent presentation to the operator, so that the preloaded pages are preloaded dynamically in response to operator selections and are available for presentation to the operator when ultimately selected.

Abstract: An improved audio-output device coupleable to a computer system, in which a DSP operating under software control emulates a common command interface. The command interface has a set of registers that are made available to the CPU for reading and writing, even if there are no such physical registers available in the device. The DSP also performs tasks in addition to audio-output, even though the audio-output device is required to respond immediately to commands from the CPU. The audio-output device has a DSP for interpreting and executing commands received from the CPU, a local memory for storing data input to or output from the DSP, a bus-interface (BIF) element for coupling the DSP and memory to a system bus, and a direct memory access (DMA) element for transferring data between the local memory and the system bus.

Two analog video signals (such as an analog VGA input and an analog ROB signal produced in response to a stored digital still or moving image) may be multiplexed in analog form.
