Abstract: A method is described that involves operating a computing system within a normal on state and transitioning from the normal on state to a main CPU/OS based state. In the main CPU/OS based state one or more components of the computing system are inactivated so as to cause the computing system to consume less power in the main CPU/OS based state than in the normal on state. The computing system is able to execute software application routines on a main CPU and a main OS of the computing system while in the main CPU/OS based state.

Abstract: The present invention discloses a method for providing full-duplex audio communication utilizing a half-duplex audio circuit in an audio communication system. The method comprises the steps of: (1) configuring an idle state, a listen state, and a talk state; (2) receiving an event triggered by one of an incoming speech, an outgoing speech, and a talk request from the half-duplex audio circuit; and (3) transitioning from one of the states to any one of the states in response to the event to provide full duplex communication.

Abstract: A server/client for a network-based multicast system has a media services manager and one or more media service providers. When functioning as a server, the media service providers receive data corresponding to a channel having one or more related data streams, where each media service provider receives data corresponding to a data stream of the channel. In the server, the media services manager receives the data from the media service providers and transmits the data to the network. When functioning as a client, the media services manager receives data from the network for a selected channel having one or more related data streams. In the client, the media service providers receive and play the data from the media services manager, where each media service provider receives and plays data corresponding to a data stream of the channel. In a preferred embodiment, a channel has logically related audio, video, and/or text data streams.

Abstract: A presentation is divided into different components. For example, a multimedia presentation may have an audio component and a video component. Each component is assigned a different network address for transmission of the presentation over the network by a server. Each receiver selects those components it wishes to play by selecting the appropriate network addresses. The presentation data is routed through the network based on the selections made by the various receivers. If, for example, one or more receivers are part of a local area network (LAN) separated from the server by a wide area network (WAN) link, and if none of those remote receivers has selected one or more of the presentation components, then the routers will not transmit data for those unselected components to the remote LAN. As a result, WAN link transmission bandwidth is preserved for desired data. In addition, the remote receivers do not have to expend processor time to examine and discard unwanted data.

Abstract: A computer system with an operating system and a data-processing system running on a host processor, and a receiver. The receiver sends interrupt signals to the operating system after the receiver has received data signals. The operating system establishes interrupt times and passes the interrupt signals to the data-processing system. The data-processing system accesses the data signals from the receiver and only partially processes the data signals during the interrupt times. The operating system also receives clock interrupt signals, which it passes on to the data-processing system. The data-processing system completes the processing of the data signals during the clock interrupt times that the operating system establishes in response to the clock interrupt signals.

Abstract: A distributed protocol for allocation of multicast addresses. A first node of a network sends an address request message identifying (1) a requested in multicast address, and (2) a multicast group identifier to which the requestor belongs. The request is in multicast on a network address reserved for address resolution. All other nodes of the network monitor the reserved network address for address request messages. If a second node receiving the address request message has already allocated the requested multicast address, then the second node sends an acknowledgment message identifying (1) the already allocated in multicast address, and (2) the multicast group for which the address has been allocated. This acknowledgment is transmitted on the same reserved network address on which the address request was sent. The first node, monitoring the reserved network address, receives the acknowledgment message.

Abstract: The transports available in a local computer system for communicating with a remote computer system are automatically determined at either install time or run time. At install time, a list of transports supported by the local computer system is used to determine which supported transports are actually installed in the local computer system and the media dependent modules (MDMs) that correspond to those installed transports. At run time, a list of the installed transports and corresponding MDMs is used to determine which installed transports (and corresponding MDMs) can actually be used for an impending communications session with the remote computer system.

Abstract: Signals (e.g., for audio/video conferencing) are divided into data packets for transmission from a local node to a remote node. The transmission of the data packets is delayed to transmit then at intervals to avoid overloading the remote node with data packets that it does not have the bandwidth to receive and/or process. The invention helps prevent the remote node from dropping data packets which may otherwise occur when transmitting audio and/or video signals during a session (e.g., an audio/video conferencing session).

Abstract: An apparatus and method for synchronizing multiple independent data streams in a networked computer system is disclosed.

Abstract: A computer-based conferencing system capable of selectively conferencing with a remote node over two or more different transports. A host processor controls the generation of local conferencing signals for transmission to the remote node over either a first transport or a second transport. The host processor also controls the processing of remote conferencing signals received from the remote node over either the first transport or the second transport. In a preferred embodiment, the first transport is an ISDN network and the second transport is a LAN network. In one embodiment, the computer system has a combined audio/ISDN board, a video board, and a LAN card. In an alternative embodiment, the computer system has a combined audio/video board, an ISDN board, and a LAN card.

Abstract: The media dependent module provides an interface between an upper-level conferencing driver (e.g., a data-link manager) of the conferencing system and a lower-level communications driver of the conferencing system to isolate the conferencing driver from the communications driver, where the media dependent module is dependent upon hardware of the communications driver. The media dependent module is adapted to perform a plurality of functions called by the conferencing driver. The media dependent module has a connection state machine. In a preferred embodiment, the communications driver is a communications stack that conforms to one of the NetBIOS, IPX, POTS Modem, and TAPI transport standards. The conferencing system may have multiple media dependent modules, each of which provides an interface between the data-link manager and a communications stack that conforms to a different transport standard.

Abstract: A method and system for loading a library requested by a service requester of an application program in a computer system. The service requester issues a request to a first loader module to load the library, where the first loader module is part of the executable application program. The first loader module passes the request to a second loader module, where the second loader module is an executable distinct from the executable application program. The second loader module then loads the library. In a preferred embodiment, the first loader module is a global dynamic loader of a multicast application program and the second loader module is a global dynamic loader executable that is an executable distinct from the executable multicast application program. A media services manager of the multicast application uses the global dynamic loader and global dynamic loader executable to load and unload one or more media service providers.
