Abstract: The invention is a technique and apparatus for re-assembling transmitted portions of files or sub-files (410, 420, 430, 440), into a viewable file (400). The transmitting device passes the information regarding the file dividing process to the receiver so that the sub-files can be assembled (1130) or stitched (1120) together properly. The media player (1140) in the receiver uses the attached instructions to assemble the sub-files into one whole piece for viewing.

Abstract: A system for generating image conversion data is provided. The system includes a numerator buffer storing numerator data of a conversion ratio, such as where the numerator of the ratio represents the relative current size of a set of image data and the denominator of the ratio represents the relative size of the target set of image data. A denominator buffer stores denominator data of the conversion ratio. A pixel sample control system receives the numerator data and the denominator data and generates pixel sample control data that is used to select a pixel from a pixel data stream, such as to allow a pixel dropping sequence or a pixel duplication sequence to be generated based on the values stored in the numerator buffer and the denominator buffer.

Abstract: Off-grid interpolation in image processing. The present invention provides for a more perceptually pleasing resultant image when compared to conventional image processing systems that employ on-grid interpolation. In one embodiment, the present invention is operable on a digital image generated using a mask having a Bayer pattern distribution. Off-grid RGB triplets are generated using the raw data received from the Bayer pattern mask. The undesirable mosaic-type images as well as the bright and dark discontinuities within the image that are often generated using conventional on-grid interpolation to generate RGB triplet are avoided when using the present invention. The undesirable cross talk effects that are practically unavoidable to some degree within all digital image masks are also substantially minimized. Bi-linear interpolation and cubic linear interpolation are employed to achieve a digital image having a high visually perceptual quality.

Abstract: One aspect of the invention involves dividing a single file (300) into multiple sub-files (310, 320, 330, 340) that are subsequently distributed and stored onto one or more servers. The sub-files (310, 320, 330, 340) may be transmitted in parallel and simultaneously from one or more servers, which increases the rate at which the data can be delivered. A second aspect of the invention involves storing at least one of the sub-files (310, 320, 330, 340) on more than one server to provide redundancy. If one server is not available, or if the transmission link is slow or not available, the sub-file can be streamed from another server. In one embodiment, each end user may receive multiple sub-files simultaneously from multiple servers. Disk input/output bandwidth is saved because only the necessary fraction of data needs to be read from each server.
