摘要： Techniques and tools for high dynamic range (“HDR”) image generation and rendering are described herein. In several described embodiments, images having distinct exposure levels are aligned. In particular embodiments, the alignment of a reference image to a non-reference image is based at least in part on motion vectors that are determined using covariance computations. Furthermore, in certain embodiments, saturated areas, underexposed areas, and/or moving objects are ignored or substantially ignored during the image alignment process. Moreover, in certain embodiments, a hierarchical pyramid block-based scheme is used to perform local motion estimation between the reference image and the non-reference image.

摘要： Methods are disclosed for supporting stereo 3D video in computing devices. A computing device can receive stereo 3D video data employing a YUV color space and chroma subsampling, and can generate anaglyph video data therefrom. The anaglyph video data can be generated by unpacking the stereo 3D video data to left and right views and combining the left and right views into a single view via matrix transformation. The combining uses transform matrices that correspond to a video pipeline configuration. The transform matrix coefficients can depend on characteristics of the video pipeline components. Modified transform matrix coefficients can be used in response to changes in the video pipeline configuration. Video encoded in stereo 3D video data can be selected to be displayed in stereo 3D, anaglyph or monoscopic form, depending on user input and/or characteristics of video pipeline components.

摘要： Disclosed herein are representative embodiments of methods, apparatus, and systems for manipulating bitstreams of digital media data compressed according to a compression standard. Also disclosed are representative embodiments of methods, apparatus, and systems for evaluating compliance of an encoded bitstream of digital media data with a compression standard. In one exemplary embodiment, a conforming bitstream of compressed digital media data is input. One or more of the parameters in the bitstream are selectively altered into parameters that do not conform to the video compression standard. The selective alteration can be performed such that parameters that would make the bitstream non-decodable if altered are bypassed and left unaltered. A non-conforming bitstream that includes the one or more selectively altered parameters is output.

摘要： Techniques and tools for reducing latency in video decoding for real-time communication applications that emphasize low delay. For example, a tool such as a video decoder selects a low-latency decoding mode. Based on the selected decoding mode, the tool adjusts output timing determination, picture boundary detection, number of pictures in flight and/or jitter buffer utilization. For low-latency decoding, the tool can use a frame count syntax element to set initial output delay for a decoded picture buffer, and the tool can use auxiliary delimiter syntax elements to detect picture boundaries. To further reduce delay in low-latency decoding, the tool can reduce number of pictures in flight for multi-threaded decoding and reduce or remove jitter buffers. The tool receives encoded data, performs decoding according to the selected decoding mode to reconstruct pictures, and outputs the pictures for display.

摘要： Techniques and tools described herein help manage memory efficiently during video decoding, especially when multiple video clips are concurrently decoded. For example, with clip-adaptive memory usage, a decoder determines first memory usage settings expected to be sufficient for decoding of a video clip. The decoder also determines second memory usage settings known to be sufficient for decoding of the clip. During decoding, memory usage is initially set according to the first settings. Memory usage is adaptively increased during decoding, subject to theoretical limits in the second settings. With adaptive early release of side information, the decoder can release side information memory for a picture earlier than the decoder releases image plane memory for the picture. The decoder can also adapt memory usage for decoded transform coefficients depending on whether the coefficients are for intra-coded blocks or inter-coded blocks, and also exploit the relative sparseness of non-zero coefficient values.
摘要翻译：这里描述的技术和工具有助于在视频解码期间有效地管理存储器，特别是当多个视频片段被同时解码时。例如，利用剪辑自适应存储器使用，解码器确定预期对视频剪辑的解码足够的第一存储器使用设置。解码器还确定已知足以解码剪辑的第二存储器使用设置。在解码期间，最初根据第一个设置设置内存使用。存储器使用在解码期间自适应地增加，受到第二设置中的理论限制。利用辅助信息的适应性早期释放，解码器可以在解码器释放用于图像的图像平面存储器之前释放用于图像的侧信息存储器。解码器还可以根据系数是用于帧内编码块还是帧间编码块来适应解码变换系数的存储器使用，并且还利用非零系数值的相对稀疏度。

摘要： Video decoding innovations for using local picture identifiers and computing co-located information are described. In one aspect, a decoder identifies reference pictures in a reference picture list of a temporal direct prediction mode macroblock that match reference pictures used by a co-located macroblock using local picture identifiers. In another aspect, a decoder determines whether reference pictures used by blocks are the same by comparing local picture identifiers during calculation of boundary strength. In yet another aspect, a decoder determines a picture type of a picture and based on the picture type selectively skips or simplifies computation of co-located information for use in reconstructing direct prediction mode macroblocks outside the picture.
