    摘要: A coding framework that provides conversions between one or more video formats without the use of a transcoder. A video information stream that includes color information formatted in accordance with a first color space sampling format is split into a base stream and an enhanced stream. The base stream is formatted in accordance with a second color space sampling format. The enhanced stream includes enhanced information that when combined with the base stream re-constructs the first format. During encoding, the enhanced stream may be encoded using spatial information related to the base information stream. An output stream of the encoded base stream and encoded enhanced stream may be interleaved, concatenated, or include independent files for the encoded base stream and the encoded enhanced stream.

    摘要: Improved video coding is described to encode video data within a sequence of video frames. To this end, at least a portion of a reference frame is encoded to include motion information associated with the portion of the reference frame. At least a portion of a predictable frame that includes video data predictively correlated to said portion of said reference frame is defined based on the motion information. At least said portion of the predictable frame is encoded without including corresponding motion information and including mode identifying data. The mode identifying data indicate that the encoded portion of the predictable frame can be directly derived using at least the motion information associated with the portion of the reference frame.

    摘要: Wyner-Ziv and wavelet video coding is described. In one aspect, Wyner-Ziv frames from multiple frames of source video content are zero-tree entropy encoded to generate encoded Wyner-Ziv content. The zero-tree entropy encoding operations are based on high-order statistical correlations among wavelet transforms from the Wyner-Ziv frames. The encoded Wyner-Ziv content is communicated to a decoder for decoding to generate reconstructed Wyner-Ziv frames for presentation to a user.

    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: A “Remote Display Generator,” as described herein, provides various techniques for providing high-fidelity displays with highly responsive interactive application experiences to clients across a wide range of network bandwidths for remotely hosted applications. In general, the Remote Display Generator uses a compression-friendly remote display architecture as a core. With this compression architecture, actual screen data from a remote server is read out from the display buffer frame by frame, and then compressed with a unified screen codec. Other technologies, including timer-driven screen update models and adaptive transmission mechanisms, are then integrated with various embodiments of the Remote Display Generator to improve overall user experience by improving display quality and responsiveness to user interaction with remotely hosted applications.

    摘要: Described is continuous network coding, in which a relay sends probability data comprising a continuous number for use as parity data. The node receives streams of bits sent from sources towards a destination, and computes the probability data based on current noise data and/or fading data. A selected set of the bits (all or some subset thereof) are combined, e.g., XOR-ed or concatenated, and send to the destination. Phase modulation is performed to convey probability information based on the probability data. The destination demodulates the signal to obtain the probability information, and combines the probability information with the data directly received from sources to perform joint decoding. The number of bits in the set of selected bits may be adaptively chosen based on current channel conditions, e.g., increased when the channel conditions from the sources directly to a destination are poor relative to the channel conditions via the relay.
