摘要:
An authentication method and system is provided for asynchronous eventing between a client and a server over the Internet. In a subscription phase, the client sends a subscription request to the server to express interest in receiving notifications associated with one or more particular events that may asynchronously occur on the server. The client authenticates the server by checking the identity of the server, and if the client determines that the server can be trusted, the client subscribes the notifications, otherwise, the client does not subscribe. After a successful subscription, in a notification phase, the server notifies each client that has subscribed for a particular type of event. Each client upon receiving a notification, authenticates the server by verifying that the received notification is sent by the server with which the client subscribed for the notification.

An eventing method and system is provided that enables resource-constrained CE devices, at home, away from home, on-the-go, or behind a firewall, to communicate through asynchronous events with each other and/or with other type electronic devices, at home or on the Internet. Further, a scalable distributed system is provided that supports asynchronous eventing over the Internet efficiently and at low cost.

A system and method for managing a group of networked, heterogeneous devices, wherein the group of devices are regarded as a logically single “device”. This method separates the state management aspect from control aspect, such that applications using this method need not manage the devices and data directly, and as a result can interact with a simplified, single ‘device’, or focus on controlling the simplified, single ‘device.

A dynamic, flexible and intuitive task-oriented graphical user interface (GUI) is implemented on network accessible hand-held mobile devices. A mobile hand-held device is characterized by limited screen size and fewer input keys compared to a keyboard. In a home network environment, such mobile hand-held devices act as remote control devices for home devices. Typical examples of such remote control device are universal remote control and cell phone. In one implementation the GUI provides techniques for displaying large amounts of data using a small screen. The GUI also presents a technique for making the user aware of current abstract available options and smoothly guiding his current intention into a task selection that the remote control can understand and execute on.

A system for providing single view of content in a network of devices includes a communication module that detects devices connected to the network, a directory module that discovers content in each detected device via the communication module and maintains a directory of such available content providing a single view of the discovered content for access thereto, and a content manager that provides access to the single view.
摘要:
A method of maintaining persistent unique identifiers for devices interconnected in a network. Information is obtained from a device and a fingerprint generated from that information. It is then determined if the fingerprint is previously associated with an identifier in the network. If the fingerprint is not previously associated with an identifier in the network, then a new identifier associated with the fingerprint is generated, and the fingerprint and the associated new identifier is stored in a memory, wherein the new identifier forms a persistent unique identifier (PUID) for that device. Otherwise, if the fingerprint is not previously associated with an identifier in the network, then the associated identifier stored in the memory is used as the persistent unique identifier (PUID) for that device.
摘要:
A method of aggregating control in a first network and a second network, the first network having first devices and the second network having second devices. A communication channel is established between the first and second networks; from the first network the second devices in the second network are discovered through the communication channel; and from the first network one of the second devices in the second network is controlled through the communication channel. The first and second network can be connected but isolated. Further, the first and second networks can implement different network protocols, or the same network protocol.
摘要:
A synchronization controller in a network of devices, provides content synchronization between the available content in the network and the content on another device. When the synchronization controller identifies the device for content synchronization with the home network, the synchronization controller attempts to match the device's content with content available in the home network. When there is a mismatch, the content manager starts a content session to transfer content from the device to the home network, or vice versa. During this process, the device need not know which home device it synchronized to, nor does it need to know what kind of format the content is stored in.
摘要:
A system and method that map services that are available on the internet to services that can be used by home network devices. Similar services are accessed by a single interface. A “light-weight” plugin mechanism is provided which enables the addition of new functionalities and services. As such, the system can be implemented in a gateway device in the network. Addition of new services can be achieved during run-time, without the need for compilation. Plugins are dynamically obtained via Web-based service providers when needed, whereby it is ensured that the user will use the version of plugins desired by Web-based service providers.
