Variable length coding for sparse coefficients 

Abstract

Coding quantized transform coefficients as occur in image compression includes, for a subset of coefficient amplitude values coding by a first method corresponding to each amplitude of the subset, events of a run of zero or more zero-valued coefficients ending in the single non-zero amplitude, coding by a second method events of a run of zero or more zero-valued coefficients ending in any single non-zero amplitude not in the subset, and coding by a third method the amplitude values of the concatenation of the non-zero amplitude not in the subset. The coding methods produce variable length codewords. The method is suitable for series that have scattered non-zero-valued coefficients.

Arrangement in a server for providing dynamic domain name system services for each received request

Abstract

A Domain Name System (DNS) server is configured for dynamically selecting, for a client device, a selected resolution from available resolutions, the selected resolution identifying at least one destination for the specified service. The dynamic selection of the selected resolution is based on an attribute of the client device and/or a determined attribute of the network. Hence, the selected resolution directs the client device to a specific server based on prescribed selection criteria, for example service level agreements, the location of the client device, network performance or detected congestion conditions, authentication of the user of the client device, etc. The selected resolution also can be for enforcement of load balancing policies.

Techniques for presenting network identities at a human interface

Abstract

Techniques for presenting identification of a remote network entity to a human user include determining one or more vectors of presentation elements that are readily distinguishable and memorable to a user. Message data is received from a remote process on the network and includes a network identity that uniquely identifies an associated remote entity. The network identity is input to a secure function to produce a secure number. A secure function produces dissimilar output values for similar input values. A particular presentation element is selected from a vector based only on the secure number and presented to the user. Even when the network identity is similar to that of a trusted entity, the particular presentation element is expected to be dissimilar to one associated with the trusted entity.

Distributed client services based on execution of service attributes and data attributes by multiple nodes in resource groups

Abstract

A network provides distributed client services based on participation in respective resource groups by computing nodes, each resource group including a corresponding resource requirement for any computing node that joins the corresponding resource group for execution of the corresponding distributed client service. Each computing node, in response to determining its corresponding available node capacity, is configured for selectively creating and joining at least one new resource group for execution of a corresponding distributed client service having a corresponding resource requirement, and/or selectively joining at least one of the available resource groups, based on the corresponding available node capacity satisfying the corresponding resource requirement. Each distributed client service also includes service attributes that define parameters for execution of the distributed client service, and data attributes that define the attributes required for data to be used in the distributed client service.

Device, methods, and user interface for providing optimized entry of alphanumeric text

Abstract

The present invention includes a device, method, and user interface for providing optimized entry of alphanumeric text. In one form, a method for providing selectable characters within a user interface includes determining an operating mode of a communication device and receiving an input associated with a selected input key. The method determines a group of characters associated with the selected key based on the operating mode and displays the group of characters within the user interface. The user interface may display a first character of the group of characters within a first portion of the user interface and the group of characters proximal to the first character within a second portion of the user interface.
