2846 results about "Application programming interface" patented technology

An application programming interface (API) is an interface or communication protocol between a client and a server intended to simplify the building of client-side software. It has been described as a “contract” between the client and the server, such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.

Method and system for partitioned service-enablement gateway with utility and consumer services

A gateway for providing consumer services is presented. The gateway includes a secure partition associated with a gateway and operable to control access to at least one utility service and a bundle associated with the secure partition. The gateway also includes a consumer service associated with the secure partition and an application programmer interface (API) bundle associated with the secure partition and providing at least one support function to the consumer service. In addition, the gateway includes a provisioning service associated with the secure partition and the API bundle, the provisioning service operable to install the consumer service, a billing service associated with the secure partition and the API bundle, the billing service operable to provide billing capabilities to the consumer service and a profile service associated with the secure partition and the API bundle, the profile service operable to store a user profile. Further, the gateway includes an authentication service associated with the secure partition and the API bundle, the authentication service operable to authorize a user associated with the gateway, a remote-logging service associated with the secure partition and the API bundle, the remote-logging service operable to log an event associated with the consumer service, and a maintenance service associated with the secure partition and the API bundle, the maintenance service operable to determine a network status associated with the gateway.

Method and apparatus for measuring stream availability, quality and performance

A streaming measurement agent designed to experience, measure, and report on a media stream as an actual end user would experience the stream. Preferably, agent resides transparently within a streaming media player itself so that it can monitor stream packet flows within the player as the measured streams are being played. In an illustrative embodiment, the agent comprises a performance monitoring module (PMM), which is software that resides in an interface between an existing core module and a renderer of a media player. The agent PMM intercepts each useful packet as it goes from the core to the renderer and, as a result, it is able to compute quality metrics about the playback. The agent functions “transparently” to the media player by presenting the core with an application programming interface (API) that emulates the API that the renderer normally presents to the core. Thus, when the core believes it is calling the renderer, it is actually calling the agent PMM, which can then receive all the packets from the core and process them. After computing relevant performance metrics using the packets it receives, the agent PMM calls the renderer. A set of performance agents can be managed by a service provider to enable a content provider to determine how a stream is perceived by end users.

Modular parallel-pipelined vision system for real-time video processing

A real-time modular video processing system (VPS) which can be scaled smoothly from relatively small systems with modest amounts of hardware to very large, very powerful systems with significantly more hardware. The modular video processing system includes a processing module containing at least one general purpose microprocessor which controls hardware and software operation of the video processing system using control data and which also facilitates communications with external devices. One or more video processing modules are also provided, each containing parallel pipelined video hardware which is programmable by the control data to provide different video processing operations on an input stream of video data. Each video processing module also contains one or more connections for accepting one or more daughterboards which each perform a particular image processing task. A global video bus routes video data between the processing module and each video processing module and between respective processing modules, while a global control bus provides the control data to / from the processing module from / to the video processing modules separate from the video data on the global video bus. A hardware control library loaded on the processing module provides an application programming interface including high level C-callable functions which allow programming of the video hardware as components are added and subtracted from the video processing system for different applications.

Internet-based shared file service with native PC client access and semantics and distributed version control

A multi-user file storage service and system enable each user of a pre-subscribed user group to operate an arbitrary client node at an arbitrary geographic location, to communicate with a remote file server node via a wide area network and to access the files of the file group via the respective client node in communication with the remote file server node via the wide area network. More than one user of the pre-subscribed user group is permitted to access the file group at the remote file server node simultaneously. Illustratively, the integrity of the files at the remote file server node are maintained by controlling each access to each file at the remote file server node so that each access to files at the remote file server is performed, if at all, on a respective portion of each file as most recently updated at the remote file server node. Thus, all native operating system application programming interfaces operate as if all multi-user applications accessing the files function as if the remote server and client nodes were on the same local area network. Illustratively, an interface is provided for adapting file access one of the client nodes. The interface designates at the client node each accessible file of the group as stored on a virtual storage device. The interface enables access to the designated files in a fashion which is indistinguishable, by users of, and applications executing at, the client node, with access to one or more files stored on a physical storage device that is locally present at the client node. Illustratively, an encrypted key is transferred from the remote file server node to one of the client nodes via a secure channel. The key is encrypted using an encryption function not known locally at the remote file server node. The transferred key is decrypted at the client node. The key is used at the client node to decrypt information of the files downloaded from the remote file server node or to encrypt information of the files prior to uploading for storage at the remote file server node. Access control to a particular one of the files of the group can be delegated to an access control node.

Method and apparatus for providing drawing collaboration on a network

A method, apparatus, and article of manufacture for an application programming interface (API) on a client computer that enables access to architectural project information stored across the internet on a server site. The server site maintains an organization for the architectural information in the form of containers for storing, managing, and sharing files for one or more architectural projects, wherein the files comprise drawings, documents, communications, and tasks related to the architectural projects. The API of the invention permits third parties to create custom clients or permit direct access to a site hosted on a server. Such an API operates with both thick (.exe) and thin (.html) clients. The API establishes / obtains a connection between the client and the server to enable such access. For example, if the user desires to store a file on the server site, the user selects the appropriate server site / folder from within an application program executing the API. The API may then require the user to logon and confirms that the user has appropriate access permissions to work with the server site / folder. Once confirmed, the connection session is established. During the session, the user may access and download files as desired while maintaining the storage structure of architectural information stored on the server site.
