A network-enabled user interface device, for example a VoIP telephony device, includes a display, a user input interface, an interface controller, and an application controller. The interface controller is configured for generating display elements for the display, controlling the user input interface based on received commands, and outputting responses to the application controller. The application controller is configured for outputting the commands to the interface controller based on application operations executed locally (i.e., within the user interface device), or remotely (e.g., by a server in communication with the user interface device). Remote application operations may include communications between the application controller and the remote server. The interface controller also may generate the display elements based on messages received from the network. Hence, the network-enabled user interface device can provide to the user interaction with arbitrary applications, executed locally or remotely, enabling any executable application to be provided to the user, independent of user action.

A synthetic code book document type definition (DTD) is generated that identifies selected compression codes, based on specifying code-book extensible markup language (XML) tags having semantics defined according to a generic code book document type definition (DTD). The compression codes are used to compress API commands, defined by second XML tags having semantics defined by a generic API DTD, into synthesized data. The synthesized data and the code-book XML tags are supplied to a destination device configured for storing the generic code book DTD and the generic API DTD, enabling the destination device to synthesize a code book for recovery of the API commands from the synthesized data.

A method and an apparatus of image compression, and a memory to store a data structure for compression. The method includes, for an ordered series of quantized coefficients of a transform of an image block, forming from the series events that are a run of non-zero-valued coefficients in a first contiguous region defined by a breakpoint, a run of zero-valued coefficients in the first region, or a run of zero-valued coefficients that ends in a non-zero-amplitude coefficient in a second region defined by the breakpoint. A codeword is formed for each runlength of non-zero-valued and zero-valued coefficients in the first region using a first and a second coding method, respectively, and, and encoding the runs of zero-valued coefficient that end in a non-zero value in the second region according to a third coding method, including providing an exception codeword when the ending amplitude is not 1.

Packets may be forwarded between realms employing private unregistered addresses without the use of network address translation and/or application level gateways. Nodes within privately addressed realms are identified by a combination of their locally significant address and a globally significant realm address. The globally significant addresses are reserved in all realms for use as realm identifiers or inter-realm routing. To send a packet to a node within a distinct private realm, the packet is given an inner IP header designating the locally significant destination IP address of the target node within the remote realm and an encapsulation IP header indicating the globally significant address advertised by the gateway of the target node's realm. The globally significant address is used for forwarding outside the realm of the destination node. Once the packet reaches the destination realm, the locally significant address is used for forwarding.
