20110069666 | METHOD AND APPARATUS FOR MANAGING ALLOCATION OF RESOURCES IN A NETWORK - To manage resource allocation between users of a wireless or wireline network, recent resource usage by each user is determined and priorities are assigned accordingly. Then, the network resources are allocated according to the assigned priorities. A respective priority of a user may be inversely proportional to the recent resource usage by that user. To facilitate continuous fair distribution of the network resources, the users may be re-prioritized and resources are re-allocated accordingly. Information about recent resource usages by the users is continuously accumulated, including about users moving from one access point of the network to another. When resource allocation for a particular access point is determined, recent resource usage for a user that has joined the access point from another access point in the network may include prior resource usage by that user at the other access point. | 2011-03-24 |

20110069763 | SCALABLE VIDEO ENCODING/DECODING METHOD AND APPARATUS FOR INCREASING IMAGE QUALITY OF BASE LAYER - Provided are a scalable video encoding/decoding method and apparatus, which may improve an image quality of a base layer while not using an anti-aliasing filter. The scalable video decoding apparatus includes an entropy decoding unit to decode an image received from an encoding apparatus, a de-blocking filter to reduce a block distortion of the decoded image, a motion compensation unit to apply a motion compensation scheme to an image passing through the de-blocking filter, a half-pel filter to apply a half-pel compensation scheme to an image where the motion compensation scheme is applied by the motion compensation unit, and an output unit to output an image where the half-pel compensation scheme is applied by the half-pel filter. | 2011-03-24 |
20110069764 | Method for Run-Length Encoding of a Bitmap Data Stream - Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time. The bitmaps are a separate layer lying above the video, e.g. for synchronized video subtitles, animations and navigation menus, and therefore contain many transparent pixels. An advanced adaptation for bitmap encoding for HDTV, e.g. 1920.times.1280 pixels per frame as defined for the Blu-ray Disc Prerecorded format, providing optimized compression results for such subtitling bitmaps, is achieved by a four-stage run length encoding. Shorter or longer sequences of pixels of a preferred color, e.g. transparent, are encoded using the second or third shortest code words, while single pixels of different color are encoded using the shortest code words, and sequences of pixels of equal color use the third or fourth shortest code words. | 2011-03-24 |
20110069765 | VIDEO DEBLOCKING FILTER - Deblocking filters are disclosed, where the nature of the filter is determined based upon the level of detail of a reconstructed video frame in the region in which the block boundary is located. One embodiment of the method of the invention includes identifying a boundary between two blocks of the reconstructed video frame, determining the level of detail of the reconstructed video frame in a region in which the block boundary is located, wherein the region includes pixels from multiple rows and multiple columns of the reconstructed video frame and includes at least one pixel that is not immediately adjacent the block boundary and selecting a filter to apply to predetermined pixels on either side of the block boundary based upon the determined level of detail. | 2011-03-24 |
