    摘要： Methods and systems are provided for maintaining the aspect ratio of an image in the form of a graphic element or a photograph on a printed product in a theme collage. The aspect ratio of each image in the theme collage is maintained independent of any aspect ratio or resolution of the theme collage. Other methods provide for maintaining the resolution of a graphic element on a printed product in a theme collage using any desired combination of bitmap or vector based graphic data and alpha data when rendering the graphic element. An exemplary system may include one or more modules for determining the size of an image on a page while maintaining an aspect ratio of the image, displaying the image, receiving graphic data for the image, receiving alpha-transparency data for the image, and changing the image appearance according to a rendering parameter.

    摘要： Described herein is a de-blocking filter arrangement for video encoders and decoders that include a de-blocking loop filter. In some embodiments, the post filter may be configured to process all edges that were not processed by the loop filter. In other embodiments the encoder may specify which edges should be processed by the loop filter and/or by the post filter. Also disclosed herein is a de¬ blocking filter arrangement for video encoders and decoders that include first and second de-blocking loop filters. The second loop filter is configured to operate only on slice boundaries that were not processed by the first loop filter, e.g., for one of the reasons described above.

    摘要： An image processing system (205) includes an image encoder system (220) and an image decoder system (230) that are coupled together. The image encoder system (220) includes an image decomposer (315) and a block encoder (318) that are coupled together. The block encoder (318) includes a color quantizer (335) and a bitmap construction module (340). The image decomposer (315) breaks an original image into blocks. Each block (260) is then processed by the block encoder (318a-nth). Specifically, the color quantizer (335) selects some number of base points, or codewords, that serve as reference pixel values, such as colors, from which quantized pixel values are derived. The bitmap construction module (340) then maps each pixel colors to one of the derived quantized colors. The codewords and bitmap are output as encoded image blocks (320). The decoder system (230) includes a block decoder (505a-mth). The block decoder (505a-mth) includes a block type detector (520), one or more decoder units, and an output selector (523). Using the codewords of the encoded data blocks, the comparator and the decoder units determine the quantized colors for the encoded image block and map each pixel to one of the quantized colors. The output selector (523) outputs the appropriate color, which is ordered in an image composer with the other decoded blocks to output an image representative of the original image. A method for encoding an original image and for decoding the encoded image to generate a representation of the original image is also disclosed.

    摘要： A system for improving throughput in a communications network, the system comprising: a first node and a second node, the first node configured to: transmit to a second node of the communication network; determine a first physical data rate for transmitting to the second node a multicast or broadcast packet; determine a second physical data rate for transmitting to the second node one or more unicast packets resulting from conversion of the multicast or broadcast packet into the one or more unicast packets; and transmit the one or more unicast packets to the second node if the second physical data rate exceeds the first physical data rate and otherwise transmit the multicast or broadcast packet to the second node.
