摘要： From a bit stream, at least the following are decoded: a stereoscopic image of first and second views; a maximum positive disparity between the first and second views; and a minimum negative disparity between the first and second views. In response to the maximum positive disparity violating a limit on positive disparity, a convergence plane of the stereoscopic image is adjusted to comply with the limit on positive disparity. In response to the minimum negative disparity violating a limit on negative disparity, the convergence plane is adjusted to comply with the limit on negative disparity.

摘要： The present invention is drawn to a device for use with first stereoscopic data, second stereoscopic data and a display device. The device includes an input portion, a convergence data detecting portion, a convergence plane portion, a comparing portion and a modification portion. The input portion can receive the first stereoscopic data and the second stereoscopic data. The convergence data detecting portion can detect first convergence data within the first stereoscopic data and can detect second convergence data within the second stereoscopic data. The convergence plane portion can determine a first convergence plane based on the first convergence data and can determine a second convergence plane based on the second convergence data. The comparing portion can compare the first, convergence plane and the second convergence plane and can generate a convergence plane comparison. The modification portion can modify the first convergence data based on the convergence plane comparison.

摘要： Disclosed embodiments relate to storing and accessing files. In an embodiment, a method includes writing a file to a writing a file to a storage device having a file system having a file allocation table (FAT). Writing the file includes allocating a plurality of clusters of the file system to the file, wherein at least a portion of the allocated clusters is contiguous. The FAT includes a plurality of cluster addresses corresponding to the allocated clusters. A signature value is stored in a cluster address corresponding to a first cluster of the contiguous clusters to indicate the presence of the contiguous clusters. In each of a set of consecutive cluster addresses succeeding the cluster address corresponding to the first cluster, a value that partially represents the number of the contiguous clusters is stored. The number of contiguous clusters is determinable by combining the values stored in the consecutive cluster addresses.

摘要： A system and method for dynamically protecting against security vulnerabilities in a reconfigurable signal chain. The system includes a signal chain formed from at least a first component connected with a second component. The first component has a set of source outputs and a first authentication block, and the second signal chain component has a set of destination inputs and a second authentication block. The system also includes a signal chain configurator that populates the first authentication block with at least one validated endpoint from the set of destination inputs. A signal chain integrity block, which is communicatively coupled with the first authentication block and the second authentication block, identifies a source-destination pair from one or more endpoint pairs formed from the at least one validated endpoint and the set of source outputs. The signal chain integrity block propagates the source-destination pair to the first authentication block and the second authentication block. The second authentication block authenticates any received input using the source-destination pair.

摘要： Frames from an image stream or streams are processed by independently operating digital signal processors (DSPs), with only frame checking microprocessors operating in a lockstep mode. In one example, two DSP are operating on alternate frames. Each DSP processes the frames and produces prediction values for the next frame. The lockstep microprocessors develop their own next frame prediction. The lockstep processors compare issued frames and previously developed predicted frames for consistency. If the predictions are close enough, the issued frame passes the test. The lockstep processors then compare the issued frame to the preceding two frames for a similar consistency check. If the prior frames are also close enough, the issued frame is acceptable. In another example, hardware checkers are provided to compare the present frame with a larger number of prior frames. The hardware checkers provide comparison results to the lockstep processors to compare against allowable variation limits.
