Abstract: A live event may be broadcasted by producing a computer coded description of the sub-events that constitute the event. The coded description is stored in a centralized computer data base and the information thus stored is accessible by a viewer's computer. That viewer computer then produces a computer simulation of the live event using the coded description.

Abstract: A system and method for data processing in which data processing tasks are arranged as separate processes, each of which can be executed by a dedicated central processing unit or by one or more shared processing units. All communication between processes takes place via streams of data items. Each stream receives data items from a single source, for example from an input to the processing system or from one of the processes. Every data item appended to a stream is associated with a unique index value--even if physical memory locations are re-used, index values never are. A process can request a data item in terms of the stream where it is stored and the index value associated with it. Within constraints imposed by physical storage capacity, any index value can be included in a request. If the data item is not yet available, execution of the process is suspended until the data item becomes available.

Abstract: A live event may be broadcast with a combination signal that includes a computer coded description of subevents that constitute the event and an audio or visual signal. The viewer's computer then provides an indication to the viewer of the occurrence of subevents of interest and allows the viewer of the event to search for such subevents in a recording of the event.

Abstract: A method and system for computer programming provides a graphical editor function for creation and editing of a computer program by manipulation of graphical images on a high-resolution display. The program is specified in terms of a definition language which can be executed by a simulation function. This function simulates execution of the program on a different, target processor as if the program were expressed in a different language which can be executed by the target processor; in addition the simulation function incorporates a simulation of the external environment of the target processor and of the interaction of the program with that environment. The graphical display of the program is animated during execution so that the user can observe and check the program's operation. When the simulated execution is satisfactory the definition-language version of the program is tanslated into the language executable on the target processor.
