A system and method for locally caching remote query replies in an electronic network comprises a local registry that performs a local query for a local software module to locate a target software element for a network messaging process. If the local query is unsuccessful, the local registry responsively creates a remote query based on the unsuccessful local query, and then broadcasts the remote query to remote registries across the electronic network. The local registry then evaluates the remote query replies and stores a remote element registration into a local cache for each successful remote query reply. The local software module may then locally identify those remote target software elements with which the local software module frequently communicates, to facilitate efficient network messaging processes.

A system and method for performing a hierarchical remote query in an electronic network comprises a local registry that classifies remote registries into discrete categories based upon the relative capability of their host devices. The local registry then broadcasts a remote query to the discrete categories of remote registries in a hierarchical sequence. The present invention thus propagates the remote query in a sequence that produces optimal likelihood of a successful remote query reply, while simultaneously conserving network resources and minimizing messaging traffic across the electronic network.

A method and system for providing basic command functionality and expanded command functionality between a plurality of devices in a network. When a first device is coupled to a home audio video network which includes a second device, a generic control module for the first device is generated by the second device. The generic control module is a basic abstraction of the capabilities of the first device. The generic control module enables the first device to respond to a basic set of commands from the second device. The second device then uses the generic control module to obtain descriptive information from the first device. The descriptive information describes the capabilities of the first device. The second device then generates a parameterized control module for the first device by modifying the generic control module based upon the descriptive information. The second device is then able to access the first device via the parameterized control module. The parameterized control module enables the first device to respond to an expanded set of commands from the second device.

A process and system for compiling an application program for a distributed adaptive run-time platform. Using the present software run-time environment, application designers would be able to quickly develop distributed adaptive software, such as network or web software, without having to deal with the details of the distribution and adaptation. In one embodiment, compile-time and run-time components configure the application execution environments depending on hints provided with the application. In order to offer application designers an easy and intuitive access to the platform services, the present invention further comprises a compiler for assisting application designers in developing the complex code required by the platform, and for providing an easy access to services provided by the platform. Particularly, the compiler parses the source codes of an application and translates pre-defined keywords into codes that are necessary for carrying out either one of the meta-space adaptation and the adaptive method mechanisms. To achieve both distribution and adaptation, meta-level object programming techniques are applied.

A method and system for managing run-time adaptation for general purpose distributed adaptive applications. Using the present software run-time environment, application designers would be able to quickly develop distributed adaptive software, such as network or web software, without having to deal with the details of the distribution and adaptation. To achieve both distribution and adaptation, meta-level object programming techniques and run-time monitoring techniques are applied. Importantly, a run-time adaptation manager is provided for configuring the application execution environments, and for managing adaptations for both reflective methods and adaptive methods. In addition, the adaptation manager coordinates the adaptation of multiple objects in a coherent manner by keeping track of instances of the adaptive classes and the platform services that they are using. The adaptation manager also records the adaptation policies and monitors the system state and user preferences. Based on the adaptation polices and the system state, the adaptation manager executes related policies and decides which, how, and when objects should be adapted.

An apparatus and method for the restoration of internal connections of consumer electronic devices in a home audio/video network. The present invention automatically maintains and manages the internal connections for each of the devices on the network. In the currently preferred embodiment, each internal connection is labeled according to its status (e.g., active or inactive) and/or condition (e.g., network compliancy). Whenever a new device is added to or an old device is removed from the network, a network reset is initiated. The network reset causes a device control module to terminate its normal mode of operation and enter into a &ldquo;restore&rdquo; mode of operation. During the restore mode, the device control module accepts connection information sent by the various stream managers of those devices currently coupled to the network. Based on this information, the device control module updates the label data for each of the internal connections. A set of rules is applied to the labels to determine whether a connection is allowed to be made by the stream manager or whether a connection is allowed to be disconnected by the stream manager. The device control manager enters back to its normal mode of operation either after all stream managers have reported or one second has elapsed.

A method and system for providing seamless interoperability and integration between a plurality of devices in a network using a common protocol, wherein at least one of the devices is a legacy device which commmunicates with the network using a proprietary protocol. When a legacy device is coupled to the network, one of the plurality of devices on the network queries the legacy device via the proprietary protocol to determine a set of basic capabilities supported by the legacy device. The set of basic capabilities are then mapped from the proprietary protocol to a set of basic commands from the common protocol. A control module is generated for the legacy device, wherein the control module is based upon the set of basic commands. The set of basic capabilites of the legacy device are then accessed via the control module, thereby providing seamless interoperability and integration of the legacy device with the plurality of devices.

Home audio video network with device control modules for incorporating

A method and system for ensuring future upgradability and expandabiliy of devices in a home audio video network. The system of the present invention generates a default control module for a first device coupled to the network by using a second device coupled to the network. The the default control module is configured to ensure at least a minimum degree of interoperability between the first device and the second device. The second device access the first device via the default control module, wherein the default control module enables the first device to respond to a default set of commands from the second device. When an updated control module for the first device is received, the default control module is replaced with the updated control module by unlinking the default control module and linking the updated control module using a registry. The updated control module can be received from a wide variety of sources (e.g., the internet, satellite broadcast, cable TV provider, disk from the manufacture, etc.). The second device subsequently accesses the first device via the updated control module, wherein the updated control module enables the first device to respond to an updated set of commands from the second device.

A method and system for providing seamless interoperability and integration of a plurality of devices in a network. When a new device is coupled to a home audio video network, the device is queried to obtain a description of first level functions supported by the device. A first level control module which implements the first level functions is generated for the device based upon the description. If the new device contains software for implementing second level functions, the software is retrieved from the device and a second level control module which implements the second level functions is generated using the software. The device is subsequently accessed via the control module in order to access the first level functions or the second level functions and provide seamless interoperability and integration of the device with the plurality of devices in the network.
