Abstract:

A method for digital image compression of a raster image is disclosed which uses different compression methods for selected parts of the image and which dynamically adjusts compression and segmentation parameters to control tradeoff of image quality and compression. The image is encoded into a single data stream for efficient handling by disk, memory and I/O systems. This system provides a stable feedback loop that manages to a fine granularity (typically 8Ã8 pixel blocks) the compression of image data so as to be compliant with a plurality of compression constraints; the management of an incremental bias toward more aggressive compression that selectively applies the more aggressive compression methods to blocks that are the most tolerant with respect to visible artifacts; and the adjustable segmentation and compression parameters used to control the image compression.

Abstract:

A method receives, at a processor of a printing apparatus, a variable information print job. The variable information print job is processed into upper planes of the record-specific objects, upper planes of the reusable objects, lower planes of the record-specific objects, and lower planes of the reusable objects. The method stores such objects within a storage medium of the printing apparatus. The method combines ones of the compressed upper planes of the record-specific objects and the compressed upper planes of the reusable objects corresponding to the record of the variable information print job using the processor to create a single compressed upper plane for the record within an output buffer of the printing apparatus and creates an ordered list (corresponding to the record) of lower plane tiles by assembling the compressed lower planes of the record-specific objects and the compressed lower plane reusable objects. The method performs a printing operation for the record of the variable information print job by decompressing multiple ones of the lower plane tiles in a predetermined order to form a lower plane of the record into an output raster page, decompressing the single compressed upper plane of the record into the output raster page, and outputting the output raster page to a printing engine of the printing apparatus to print the record of the variable information print job on print media.

Abstract:

A method and system for predicting expansion difficulty and an expansion time required to perform print-time imaging operations. A print-ready compressed file may be generated by raster image processing of a job description file associated with a rendering job provided by a digital front end. The expansion time with respect to one or more expansion processes may be predicted by a linear equation during assembly of the compressed file. The linear equation may be formulated based on measured compression statistics that relate to profile data within the compressed file. The total expansion time with respect to the rendering job may be then computed by summing the results of the linear equations. The expansion time to perform the print-time imaging operations may be compared with an available time based on an image output terminal speed to improve performance of raster image processing.

Abstract:

The present invention relates to a methodology for assembling a document from content spanning multiple web-pages. Given a starting location, one process analyzes a single page at a time to find candidate links. The links are recursively followed and those pages are analyzed. A detailed set of heuristics is used to determine what is or is not a candidate link. The candidate pages are then optionally fed to a document-level analyzer. This process compares the attributes of one page against the others and looks for a document-like structure. Using another detailed set of heuristics, the document-level analyzer determines if the page should be included in the document.

Abstract:

The present invention relates to a methodology for assembling a document from content spanning multiple web-pages employing two cooperative processes. Given a starting location, one process analyzes a single page at a time to find candidate links. The links are recursively followed and those pages are analyzed. A detailed set of heuristics is used to determine what is or is not a candidate link. The links are examined for link clusters and a table of contents if found is identified. The candidate pages are then fed to a document-level analyzer. This process compares the attributes of one page against the others and looks for a document-like structure. Using another detailed set of heuristics, the document-level analyzer determines if the page should be included in the document.

Abstract:

A system and method for automatically establishing a concurrent data connection between a communications device and a remote data server upon initiating a voice call. A data connection application can be configured in association with a communications device in order to concurrently connect the communications device and a remote data server on initiating a voice call. A directory server can be employed to match an outgoing contact number with respect to the communications device with a list of data-active contact numbers stored in the directory server. If a match is found, the location data can be transmitted to the communications device. The data connection application can be further communicated with the remote data server in order to visually transmit a wide range of potential business application associated with the remote data server to the communications device.
