An audio system comprises an audio source terminal 11 and a audio playback terminal 13, connected to each another by a wireless data link 14. The source terminal 11 comprises a source computer 15, and a cellular modem 17. The playback terminal 13 comprises a playback computer 19 having an internal processor 23 and an audio processor 24. Connected to the processor 23 is a cellular modem 21, an audio transducer 25, and a user control 27. Data relating to audio components, representing different services, is stored at the source terminal 11 where it is spatially processed and transmitted to the playback terminal. At the same time, each individual audio component is transmitted at a lower bit-rate than the spatially processed data, to the audio source terminal 11, whereafter it is spatially processed. Although the low bit-rate transmission causes a loss of audio quality, the positional data remains unaffected. Accordingly, when played, the combination of a high quality signal with low three-dimensional audio positional accuracy, and a set of low quality signals with high three-dimensional audio positional accuracy, results in restoration of the human perception of three-dimensional position to the degraded three-dimensional audio signal.

An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. The interface is generated by apparatus that includes functionality for determining for each sound source, a rendering position at which the sound source is to be synthesized to sound in the audio field. To facilitate discrimination between the synthesized sound sources, the sound-source rendering positions are adjusted such that the audio field is dilated in a region of the audio field about a focus reference; this focus reference is, for example, the current direction of facing of the user or the position of an audio cursor in the audio field.

Modelling a computer based business process having a number of functional steps, involves providing software candidate models (740) of the business process, each specifying the functional steps (750), an arrangement of software application components (770) for carrying out the functional steps, and a design of computing infrastructure (780), for running the software application components, to meet given non functional requirements, and suitable for automated deployment. For each of the candidate models, operation of the business process is simulated (730) according to the respective candidate model and their simulated operation is evaluated against the non-functional requirements. The simulation can help the search for a suitable or optimum deployment to be more efficient and can lead to more efficient usage of shared resources.

A method of setting up a development environment for development work on a computer based business process, involves providing a software model (827) of the business process, and providing in the model a representation (870) of tools for developing part of the process, incorporated with the corresponding part of the modelled business process. The selected parts of the model incorporating the tools are deployed, and the given tools installed, to set up the development environment. By modelling the development tools incorporated in the business process, setting up the development environment can be made easier. Choice and arrangement of tools needs less manual input, so risks of errors, and time spent in setting up can be reduced.

A user is pre-qualified for a service provided at a particular location. Location data indicative of where the service is to be triggered and a service element are stored. The service instance element is a full customised instance of the service delivery code or other item that provides an association between the user and an instance of the service for which the user is qualified. The user location, as indicated by a mobile entity associated with the user, is periodically checked against the location data. When a location match occurs, the service instance for which the user has been qualified is executed to deliver the required service to the user. An example is an airline traveler buying, from a travel agent, an air ticket having an associated service wherein, the traveler, upon arriving at the relevant airport, is contacted via its mobile device and guided through check-in and boarding.

There is provided a non-transitory machine-readable storage medium encoded with instructions executable by a processor. The machine-readable storage medium comprises a graph database comprising first-level vertices and first-level edges, each first-level edge linking two first-level vertices, wherein each first-level vertex represents an entity and each first-level edge represents a relationship between two entities. The machine-readable storage medium further comprises instructions to: responsive to a generation of a result set for a query on the graph database, add a second-level vertex to the graph database, wherein the second-level vertex represents the result set of the query; and add a second-level edge to the graph database, wherein the second-level edge connects the second-level vertex to a first-level vertex.
摘要:
A method is provided for inviting an assistant entity, such as a customer service representative acting through a endpoint system, into an existing network communication session established by a service system. The service system controls the joining of endpoint entities to the session and enables endpoint entities joined to the session to communicate with each other. The method involves a first party associated with an endpoint system already joined to the session, indicating to the service system that the presence of an assistant entity is required. The service system selects an appropriate assistant entity taking account of the current context of the communication session, and joins the selected assistant entity to the session.

Systems and methods for information technology system change planning are described. In an information technology system change planning method in accordance with an embodiment, a change request is received on a network server (310). Domain objects and dependencies among domain objects are identified to form a model (320). Refinable tasks, atomic tasks, and state transitions are selected from a knowledge base based on the change request and the model (330), including dependencies. A workflow is created for implementing the change request using a processor (340). The workflow can be based on the model and may include a combination of selected refinable tasks, atomic tasks, and state transitions used to implement the change request.
摘要:
A content-provider entity provides content to media channels established in respect of a network communication session. The content-provider entity has a transport subsystem for establishing media channel connections to a session transport mechanism in accordance with channel type and connection details received by the entity. The content-provider entity also has a media subsystem providing a respective media handler of appropriate type for each media channel connection established by the transport subsystem. Each media handler is responsible for delivering media content of its associated type from a media source to the corresponding channel connection. A delivery controller of the media subsystem controls the selection and delivery of media content through the media handlers in dependence on context data supplied to the content-provider entity.
摘要:
An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. At least some of the sound sources are associated in a collection as members of the collection; the collection itself has an associated collection-representing sound source. The collection can be changed in either direction between an un-collapsed state in which the member sound sources are present un-muted in the audio field, and a collapsed state in which the member sound sources are muted with the collection-representing sound source providing an audible presence for the collection in the audio field.
