Abstract: When the name of a resource is inputted to a given context holder, a name analysis unit analyzes the name and a name translation unit converts it into first or second resource implementation representations. A name resolution unit receives the first or second resource implementation representations from each context holder. When the result of conversion is of the second resource implementation representations, the name resolution unit outputs a resource name of a second series or string of resource elements included in the second resource implementation representations to its corresponding context holder. This operation is executed on a chain basis to solve the name. A resource implementation unit outputs a handle for the resource corresponding to the result of name resolution therefrom. A user can obtain access to a virtual resource corresponding to the input name by using the handle.

Abstract: One page of image data is divided into six data streams of blocks data. First to sixth FIFO memories of a speed difference absorbing circuit absorb a difference between a transfer rate of the block data and a processing speed of the subsequent circuits. FIFO memories of a line delay circuit delay the respective block data such that delay times for the respective block data change step by step by a predetermined time. An order conversion circuit produces 4-line parallel image data by sequentially selecting the block data sent from the line delay circuit. Sync signals for the four respective lines are delayed step by step by a predetermined time.

Abstract: A system and method for pipelined data processing emulates multi-tasking pipelined data processing in a single tasking environment. A host application running in the single tasking environment creates a pipeline of linked data processing tasks to process data from a data source and to provide the processed data to the host application. As each data processing task of the pipeline is created, the task calls an external procedure to obtain header data indicative of the data to be received by the task. Each task alters the obtained header data to reflect the data processing operation to be performed by the task, then the task creates an external procedure callable by other tasks or the host application. The external procedure provides the processed header data from within a task to the calling task or host application. After all tasks of the pipeline are created the host application invokes the pipeline to obtain processed data from the pipeline.

Abstract: An image communication system wherein transmission of an image between an image transmission apparatus and an image reception apparatus which include image output sections having different performances can be performed without making an inquiry for the performance prior to transmission is disclosed. An image is inputted by an image input section and sent to a hierarchization section in the image transmission apparatus. The hierarchization section converts the inputted image into and transmits hierarchized data to a selection section of the image reception apparatus. The selection section extracts only necessary ones of the data transmitted thereto in accordance with the performance of an image output section of the image reception section and then sends the necessary data to the image output section after, if necessary, they are converted into image data. The image output section visualize the image data transmitted thereto from the selection section.
