  • Patent number: 10075710
    Abstract: A particular implementation receives a bitstream and derives parameters from the bitstream. The parameters include quantization parameters, content unpredictability parameters, ratios of lost blocks, ratios of propagated blocks, error concealment distances, motion vectors, durations of freezing, and frame rates. Using these parameters, a compression distortion factor, a slicing distortion factor, and a freezing distortion factor are estimated respectively for distortions resulting from video compression, a slicing mode error concealment, and a freezing slicing mode error concealment. The distortion factors are then mapped to a composite video quality score. For applications with limited computational power, the estimation of distortion factors can be simplified. In particular, the compression distortion factor, the slicing distortion factor, and the freezing distortion factor can be predicted from quantization parameters, ratios of lost blocks, and durations of freezing, respectively.

  • Patent number: 8934026
    Abstract: A method is provided in one example embodiment and includes receiving a camera dynamic parameter; determining a reference transform parameter based on the camera dynamic parameter; applying the reference transform parameter to generate a video image; and encoding the reference transform parameter in a bitstream for transmission with the video image. In other more specific instances, the method may include decoding a particular video image; decoding a particular reference transform parameter; and applying a particular reference transform parameter to the particular video image. The entropy-decoded data can undergo inverse quantization and transformation such that reference transformed data is combined with the entropy-decoded data. Additionally, the entropy-decoded data can be subjected to filtering before decoded video images are rendered on a display.

  • Patent number: 8924816
    Abstract: A method and system to improve the performance and/or reliability of a solid-state drive (SSD). In one embodiment of the invention, the SSD has logic to compress a block of data to be stored in the SSD. If it is not possible to compress the block of data below the threshold, the SSD stores the block of data without any compression. If it is possible to compress the block of data below the threshold, the SSD compresses the block of data and stores the compressed data in the SSD. In one embodiment of the invention, the SSD has logic to dynamically adjust or select the strength of the error correcting code of the data that is stored in the SSD. In another embodiment of the invention, the SSD has logic to provide intra-page XOR protection of the data in the page.

  • Patent number: 8898337
    Abstract: Exemplary methods, computer systems, and computer program products for processing a previously compressed data stream in a computer environment are provided. In one embodiment, the computer environment is configured for separating a previously compressed data stream into an input data block including a header input block having a previously compressed header. Sequences of bits are included with the input data block. Compression scheme information is derived from the previously compressed header. The input data block is accessed and recompressed following the header input block in the previously compressed data stream one at a time using block-image synchronization information. Access to the block-image synchronization information is initialized by the compression scheme information to generate an output data block. The block-image synchronization information is used to provide decompression information to facilitate decompression of the results of the output data block.

  • Patent number: 8890963
    Abstract: The present invention evaluates the quality of an image shot by a terminal device in a state closer to that seen with the eye. A computer evaluates the quality of an image obtained by shooting a photographic subject including a periodic pattern that fluctuates periodically in one direction. A Fourier transform unit accomplishes a two-dimensional Fourier transform on the image to obtain two-dimensional spatial frequency spectrum components. An analysis unit analyzes the resolution of the image on the basis of spectrum components of spatial frequencies included in the periodic pattern, among the two-dimensional spatial frequency spectrum components obtained by the Fourier transform unit, and analyzes the deterioration of the image on the basis of spectrum components other than these.

  • Patent number: 8890930
    Abstract: The present invention provides a multi-channel video communication system which includes a scalable video codec, a bit-stream truncating module, a network module and a multi-channel bit-stream truncating control module. The scalable video codec encodes a video source to generate a scalable original video bit-stream. The bit-stream truncating module is set between the scalable video codec and the network module, truncates the original video bit-stream to obtain a final video bit-stream and sends the final video bit-stream to the remote client device through the network module. The multi-channel bit-stream truncating control module is connected with the bit-stream truncating module, calculates a filter parameter for each bit-stream truncating unit in the bit-stream truncating module based on received device capabilities and network conditions of the remote client device. The present invention also provides a multi-channel video communication method in the above multi-channel video communication system.

  • Patent number: 8885014
    Abstract: Methods and systems for presenting video images generated by multiple endpoints in a videoconference such that the displayed images have consistent appearance, for example consistent brightness levels are disclosed. Sampling methods and algorithms are used to calculate an appropriate amount of correction for each video image and the images are adjusted accordingly. Brightness correction may implement one or more brightness sampling and analyzing logical modules (BSAM) and one or more transforming logical module (TLM). The brightness matching methods may be implemented in centralized architecture, for example, as part of a multipoint control unit (MCU). Alternatively, the methods may be implemented using a distributed architecture.

  • Patent number: 8872933
    Abstract: A video camera can be configured to highly compress video data in a visually lossless manner. The camera can be configured to transform blue and red image data in a manner that enhances the compressibility of the data. The data can then be compressed and stored in this form. This allows a user to reconstruct the red and blue data to obtain the original raw data for a modified version of the original raw data that is visually lossless when demosaiced. Additionally, the data can be processed in a manner in which the green image elements are demosaiced first and then the red and blue elements are reconstructed based on values of the demosaiced green image elements.

  • Patent number: 8872881
    Abstract: A combined video image is created from a plurality of video images. Each video image has a plurality of video image components, and each video image component has an image component header. The image header is removed from each video image to be included in the combined video image, and a new image header is generated for the combined video image. The image component header of each video image component to be included in the combined video image is altered to set an image position for the video image component within the combined video image. The combined video image is generated by concatenating the new image header with the plurality of video images having no image headers and the video image components having the altered image component headers.
