    摘要: One aspect of the invention relates to a method for synchronizing control signals with scaled digital video data. In one version of the invention, the method includes the steps of transferring digitized video data from a digitizer to a video scaler which stores the digitized video data to form pixel data and generates a pixel qualifier signal to indicate when pixel data is valid; storing the pixel data into a field memory in response to the pixel qualifier signal from the video scaler; storing control signal data in a control memory in response to the pixel qualifier signal, the control signal data being representative of control signals provided by the video scaler, such that a correspondence is created between the pixel data stored in the field memory and the control signal data stored in the control memory; and transferring the pixel data stored in the field memory and the control signal data stored in the control memory to a bus interface unit, the bus interface unit being coupled to a data bus of a host processor, such that the correspondence between the pixel data and the control signal data is maintained during the transfer.

    摘要: A methodology for providing a single-sign-on mechanism within an ASP aggregator service is presented. An aggregator token is generated by an ASP aggregator service and sent to a client device after its user has been successfully authenticated during a single-sign-on operation that is provided by the ASP aggregator service. The aggregator token then accompanies any request from the client to aggregated applications within the ASP aggregator service's infrastructure. The aggregator token comprises an indication of an address or resource identifier within the ASP aggregator service to which a client/user can be redirected when the client/user needs to be authenticated by the ASP aggregator service. In other words, the address/identifier is associated with a logon resource; when a request from a client is sent to this address, the ASP aggregator service responds with an authentication challenge to force the user to complete a single-sign-on operation.

    摘要: An apparatus and method for deploying web services in a web services infrastructure are provided. With the apparatus and method, a deployment descriptor for a web service is retrieved from a configuration file. A location type in the deployment descriptor is provided for identifying whether the web service is implemented using a web services description language (WSDL) document only, a JavaBean only, or both a WSDL document and a JavaBean. Based on the location type, and associated attributes of the location type, processes are performed for generating an internal definition of the web service to thereby deploy the web service in the web services infrastructure. The internal definition may be generated from the WSDL document directly, if the location type is WSDL only. If the location type is JavaBean only, the internal definition may be generated by first generating a WSDL document from the JavaBean and then generating the internal definition from the generated WSDL document. If the location type is both a WSDL document and JavaBean, then the internal definition is generated from the WSDL document with a Java binding being added to reference the JavaBean.

    摘要: A method for processing a Document Object Model (DOM) tree to verify context between multiple related XML tags. One or more of these related XML tags are custom tags. According to the invention, contextual relationships between the related XML tags are verified using the DOM itself to indicate state. In a preferred embodiment, the inventive method begins during the processing of the DOM tree with a current element being processed replacing itself with a placeholder element. The placeholder element includes attributes indicating its state. If a clean-up element does not already exist for the element being processed, the current element creates a clean-up element and adds it to the DOM, for example, as a child node to the root position. When the clean-up element is later encountered, this element scans the entire DOM for all the related tags (now placeholders) of interest. The clean-up element loads the state information from each and processes the state information accordingly. When complete, the clean-up element removes itself from the DOM.
