摘要： A method for compressing textures. A first block of texels is transformed from a red-green-blue (RGB) space to a second block of texels in a luminance-chrominance space. The first block has red values, green values and blue values. The second block has luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The chrominance values may be sampled for a first subset of texels in the second block. The luminance values and the sampled chrominance values may be converted to an 8-bit integer format. The luminance values of the first subset may be modified to restore a local linearity property to the first subset. The second block may be compressed into a third block.

摘要： A method for compressing a high dynamic range (HDR) texture. A first block of texels of the HDR texture in a red-green-blue (RGB) space may be transformed to a second block of texels in a luminance-chrominance space. The first block may have red values, green values and blue values. The second block may have luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The luminance values and the chrominance values may be converted to an 8-bit integer format. The luminance values may be modified to restore a local linearity property to the second block. The second block may be compressed.

摘要： Progressive distributed video coding is described. In one implementation, video data maybe encoded by arranging the data into bit-planes. The arrangement of bit-planes is adapted by shifting the first non-zero bit-plane left by one place in the binary digits and moving the sign bit immediately in the place vacated by the shifted non-zero bit-plane. The adapted bit-planes are then encoded using an asymmetric Slepian-Wolf encoder.

摘要： A technique is described for compressing textures for use in a graphics application, such as a 3D game application. The technique includes parsing first-compressed texture information (e.g., S3TC texture information) into respective components of the first-compressed texture information (such as main color information, color index information, main alpha information, and alpha index information). The technique then further compresses the respective components to yield second-compressed texture information (referred to as modified compressed texture information or MCT texture information). The MCT texture information can be stored and then decoded to reconstruct the original S3TC texture information for use in the graphics application. Compared to the use of unmodified S3TC texture information, the technique allows more economical storage of texture information, as well as more efficient loading of the texture information from storage to memory.

摘要： An architecture provides adaptive access to scalable media codestreams. Minimum coding units from the codestream to facilitate presentation of the media content at a selected access level are collected in packettes. The data needed for the packettes are identified and assembled by a peering subsystem or peer layer that supplements a conventional architecture in a sending system. The packettes are communicated to one or more receiving systems, such as by collecting the packeftes into transport packets recognized by conventional architecture. The peering subsystem or peering layer of a receiving system unpacks the packeftes needed to support the desired access level to the media content. The peer subsystems or peer layers communicate between systems to effect changes in the packettes provided to adapt access levels or avoid waste of network resources. The architecture supports applications including multiple access level streaming of media content, device roaming, and time-dependent access level shifting.

摘要： A method and system for coding a multi-view video having multiple views based on temporal decomposition and view decomposition is provided. A multi-view video coding (“MVC”) system provides a disparity compensated view filter based on a generic lifting transform that is used in conjunction with a motion compensated temporal filtering and a two-dimensional spatial discrete wavelet transform to decompose a multi-view video into four-dimensional wavelet coefficients. The MVC system performs a hierarchy of decompositions for each view that may be a combination of temporal decompositions and view decompositions.

摘要： Techniques and tools are described for scalable video coding and decoding. For example, a 3D sub-band decoder receives video encoded using spatial-domain motion-compensated temporal filtering at a first spatial resolution. The decoder decodes at least part of the video for output at a second spatial resolution lower than the first spatial resolution. The decoder uses any of several techniques to improve performance by devoting extra computational resources to the decoding, devoting extra buffer resources to storing reference picture information, and/or considering spatial high-pass sub-band information.
