摘要： A Wyner-Ziv coding scheme jointly utilizes multiple side information at the decoder is described. A new probability model is introduced based on an extended turbo decoding trellis, so that the transitional probability is calculated from the probabilities conditioned on multiple side information. The proposed scheme handles multiple side information in a multi-dimensional manner to potentially achieve coding performance better than either selecting one side information or generating a single side information by averaging several side information. When the decoder receives multiple streams of parity bits, the conditional probabilities on the parity bits from the multiple streams all contribute in turbo decoding. The errors existing in some of the streams can be automatically eliminated during the decoding process.

摘要： Computation scheduling and allocation for visual communication is described. In one aspect, multiple frames of video data are encoded by allocating for at least a subset of inter-coded frames, on frame-by-frame basis, computational resources to encode the inter-coded frame. To this end, a computational budget to encode a current inter-coded frame is estimated. The estimate is based on the actual computational costs to encode a previous inter-coded frame of video data. Next, sets of operations associated with encoding the current inter-coded frame are analyzed to determine computational resources to implement the operations. If the computational resources exceed the computational budget, complexity of the operations is reduced until the associated computational resources are less than or equal to the computational budget. At this point, the current inter-coded frame is encoded using the operations and the computational budget. This process is repeated for the remaining inter-coded frames of video data.

摘要： A proxy-based thin-client web browsing framework enables cooperative web browsing of multiple devices. The multiple devices may include devices that are not intended for web browsing and have limited or no web browsers and/or user input capabilities. The proxy-based thin client web browsing framework employs a virtual browser at a proxy server to perform all browser-engine logics, and retrieve, render and encode web pages on behalf of the multiple devices. The multiple devices therefore only need to have limited decoding and display capabilities to perform web browsing. The proxy-based thin client web browsing framework further includes a touch controller as a remote controller for a device that has no or limited user texting or manipulating capabilities.

摘要： Techniques describe providing a web page for a proxy-based browser on a mobile device to enhance user experience. A proxy server receives a layout of the web page, extracts web elements from the web page, and captures images of the web elements of the web page. The web elements are incorporated with a background screen image to form a composite screen format to represent a display of the web page. The background screen image is compressed by splitting an encoded frame into fixed-size slices and splitting a previous screen frame into fixed-size slices. The proxy server provides the web page synchronized with the mobile device based on the composite screen format and the compressed background screen image. Furthermore, the proxy server receives input from a user to provide updates to web elements that are dynamic on the web page to be displayed on the screen of the mobile device.

摘要： Techniques for setting depth values for invalid measurement regions of depth images are described herein. A computing device may set the depth values based on evaluations of depth values of neighboring pixels and of corresponding pixels from time-adjacent depth images. Alternately or additionally, the computing device may utilize a texture image corresponding to the depth image to identify objects and may set depth values for pixels based on depth values of other pixels belonging to the same object. After setting the depth values, the computing device may normalize the depth values of the pixels. Further, the computing device may generate reduced representations of the depth images based on a depth reference model or a depth error model and may provide the reduced representations to an encoder.
