The invention provides a method and system for dynamic downloading of hypertext electronic mail messages. The system includes a mail server for receiving electronic mail messages and their headers, and a mail client for downloading electronic mail messages and their headers from the mail receiver and presenting downloaded electronic mail messages and headers to an operator. The mail client dynamically downloads and presents electronic mail messages responsive to interactive instructions from an operator, preloads and stores electronic mail messages for subsequent presentation to the operator, and organizes electronic mail messages in hypertext sections for selection by and presentation to the operator. The mail server and the mail client cooperate dynamically and interactively to download, so as to present to the operator, electronic mail messages, or portions thereof, linked by hypertext links and possibly including data, audiovisual material, included programs, security features, or other features in addition to text.

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. The local memory has an emulation region for emulating a set of named registers the CPU may read from and write into according to the command interface, and a communication region for transmitting messages between the CPU and the DSP. The emulation region is indicated by a base register and a set of offset values, and has a dynamically allocated set of registers for emulating the set of named registers the CPU may read from and write into.

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 and the second video signal may be adjusted so that they reach the monitor screen (by means o a multiplexer output) at the same time. An alignment detector may attempt to align chromakey mixer until the time difference between the first and the second video signals falls below a threshold.

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.

The invention provides a method and system for providing features for internet access at an internet appliance which go beyond the resource limitations of the internet appliance. The desired features are primarily 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.

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 âweb browserâ) 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. The page server and the page client may act independently or may cooperate so as to dynamically select and preload pages from the page server to the page client using parameters indicated by the page client (such as parameters selected by the operator or adaptively determined by the page client), parameters indicated by the web server (such as parameters selected by the page under presentation or adaptively determined by the page server), or parameters indicated by links to those subsequent pages, or responsive to a combination thereof. The page client may dynamically save and recall behavior information about pages to be presented, such behavior information possibly being independent of actual links indicated on the pages. The behavior information may be responsive to parameters selected by the operator parameters adaptively determined by the page client, or responsive to a combination thereof.

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 âtheme,â which presents a variant of each multimedia object consistent with the theme.
