20090010059 | Memory Arrangement, Particularly for the Non-Volatile Storage of Uncompressed Video and/or Audio Data - When recording uncompressed video and/or audio data using a digital video recorder, there is the need for a robust memory arrangement based on non-volatile, integrated circuits which is able to be fitted directly on the video camera without a long external cable connection and which is also able to be used for shots under difficult conditions, particularly action shots. The inventive memory arrangement involves the use of a number of non-volatile memory chips which are connected together with a favorable level of circuit complexity. To be able to cope with the high data rate for the incoming video and/or audio data, a plurality of parallel supply buses are provided. Each supply bus has an associated number of memory chips. In this case, the memory word length of the memory chips is greater than the bus width of a data/address bus. A supply bus with high-quality multiplexing has a respective associated number of demultiplexer/driver circuits which match the bus width of the supply bus to the memory word length of the memory chips. There are respectively as many downstream memory chips per demultiplexer/driver circuit as prescribed by a value X, the value X being limited by the memory technology used, namely by the maximum number of circuits which can be connected, also called the “fan-out” value. The memory chips used are preferably NAND Flash EPROM memory chips. | 01-08-2009 |
20090059737 | Method for storing files on a storage medium, storage medium, and video recording apparatus using the method - In a storage medium, an address space is defined which is divided into a first area and a second area. According to the invention, at least one file is stored on the medium which is split into small data packets and large data packets. All small data packets are stored on said first area, and all large data packets are stored on said second area. A single file allocation table (FAT) is used and is small by having one entry per data packet. | 03-05-2009 |

According to the invention, an arrangement for adaptive bit recovery including an adaptive equalizer and an adaptive partial response maximum likelihood detector further includes an overflow control block for the adaptive equalizer for monitoring one or more of the adaptation coefficients and/or a state violation checker for monitoring the allowed states and indicating state violations as well as and a noise detector for detecting larger deviations of the target values. | 02-18-2010 |
20100040149 | 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. | 02-18-2010 |

20130301933 | METHOD AND DEVICE FOR GENERATING A SUPER-RESOLUTION VERSION OF A LOW RESOLUTION INPUT DATA STRUCTURE - The invention relates to an improved robustness in upscaling the resolution of regularly sampled multi-dimensional signals, where a single low-resolution signal is available. These methods are referred to as example-based super-resolution or single-image super-resolution. A method for super-resolving a single image comprises three stages. First, an interpolation-based up-scaling of the input image is performed, followed by a Local De-noising step in contour regions. The second stage comprises extrapolation through cross-scale block matching, wherein an extrapolated high-frequency band is obtained that is de-noised through regularization in the same contour regions. The third stage comprises adding the contributions of the low-frequency band of the high-resolution image and the extrapolated high-frequency band. | 11-14-2013 |

A motion estimation stage estimates motion of the pixels of the image. A point spread function modeling stage models point spread functions for the pixels of the image using the motion estimates. A deconvolution stage determines a deblurred estimate of the image using the modeled point spread functions. A feedback loop allows iteratively improving the motion estimates for the pixels until the modeled point spread functions converge. | 09-11-2014 |
20150023611 | METHOD AND DEVICE FOR GENERATING A SUPER-RESOLUTION VERSION OF A LOW RESOLUTION INPUT DATA STRUCTURE - The invention relates to the improvement of the resolution of regularly sampled multi-dimensional signals, where a single low-resolution signal is available. These methods are generically referred to as example-based super-resolution or single-image super-resolution. The method for super-resolving a single image comprises three stages. First, an interpolation-based up-scaling of the input image is performed, followed by an equivalent low-pass filtering operation on the low-resolution image. The second stage comprises a search for low-frequency matches between an inspected patch in the high-resolution image and patches in a local neighborhood in the low-resolution low-frequency image, including partly overlapping patches, and accumulating the high-frequency contribution obtained from the low-resolution image. The third stage comprises adding the contributions of the low-frequency band of the high-resolution image and the extrapolated high-frequency band. | 01-22-2015 |
