摘要： A system and method for calculating audio processing attribute in digital signal processing system are provided. A testing system generates a multi-channel test signal in which one channel is returned to the testing system and the other channel is sent to a tested system. The test signals are processed, mixed and correlated. The resulting differences in the correlated signals are used to calculate various processing attributes of the tested system.

摘要： Video decoding innovations for multithreading implementations and graphics processor unit (“GPU”) implementations are described. For example, for multithreaded decoding, a decoder uses innovations in the areas of layered data structures, picture extent discovery, a picture command queue, and/or task scheduling for multithreading. Or, for a GPU implementation, a decoder uses innovations in the areas of inverse transforms, inverse quantization, fractional interpolation, intra prediction using waves, loop filtering using waves, memory usage and/or performance-adaptive loop filtering. Innovations are also described in the areas of error handling and recovery, determination of neighbor availability for operations such as context modeling and intra prediction, CABAC decoding, computation of collocated information for direct mode macroblocks in B slices, reduction of memory consumption, implementation of trick play modes, and picture dropping for quality adjustment.

摘要： This document describes techniques for, and apparatuses capable of, provider-specific parsing for content retrieval. In one embodiment, a user's computing device receives code (e.g., an executable script) from a content provider and utilizes a parsing scheme associated with the content provider to parse the code and determine an address that can be used to retrieve an instance of content. The instance of content can then be retrieved using the address and without executing the code. In some embodiments, the parsing scheme is specific to the content provider and can be updated based on a change to the code.

摘要： Error concealment techniques for video decoding are described. For example, a video decoder after finding a corrupted picture in a bit stream, finds a suitable neighbor for the corrupted picture. For example, the video decoder favors pictures with the same parity as the corrupted picture and considers picture order count and picture corruption in choosing a neighbor. The decoder then modifies syntax elements for the encoded video in the bit stream to allow the neighbor to be used in concealing the corruption in the corrupted picture. The modification of syntax elements can depend on the particular video decoder implementation. For example, in a software-only multithreaded video decoder, a task graph is modified, while in a system utilizing video acceleration, syntax elements for reference lists are modified.
