摘要： Methods and systems are provided for synchronizing various time-stamped data streams. The data streams can be synchronized to another data stream or to a point of reference such as a reference clock. In one embodiment, synchronization processing takes place in association with a filter graph comprising multiple filters. The filter graph is configured to process multiple timestamped data streams for rendering the data streams in accordance with data stream timestamps. A synchronization module is provided and is associated with the filter graph queries individual filters of the filter graph to ascertain input timestamp-to-output timestamp mappings. The module computes adjustments that are to be made to output timestamps in order to synchronize the data streams, and then instructs queried filters to adjust their output timestamps in accordance with its adjustment computations.

摘要： Strategies for effectively discovering, selecting, configuring, and controlling components used in media processing applications are described. According to one exemplary implementation, the strategies described configure the components based on profile information, configuration information, and a hierarchical ordering of configuration parameters. The hierarchical ordering may combine different coding paradigms, where one or more high level nodes in the ordering may define configuration parameters which are common to multiple coding paradigms. In this ordering, selection of a configuration parameter may cascade down to affect lower-ranking dependent parameters in the hierarchical ordering. According to one advantage, the hierarchical ordering provides a more uniform, extensible, and problem-free approach to configuring components than unstructured approaches to configuration. Moreover, applications can utilize the hierarchical ordering at different levels of granularity.
摘要翻译：描述了有效发现，选择，配置和控制媒体处理应用中使用的组件的策略。根据一个示例性实现，所描述的策略基于简档信息，配置信息以及配置参数的分级排序配置组件。分层排序可以组合不同的编码范例，其中排序中的一个或多个高级节点可以定义多个编码范例共有的配置参数。在该排序中，配置参数的选择可以级联以影响分级排序中的较低级别的依赖参数。根据一个优点，分层排序提供了比非结构化配置方法更为统一，可扩展和无问题的配置组件的方法。此外，应用程序可以以不同的粒度级别利用分层排序。

摘要： Methods for mapping color data having at least one color associated therewith to an output device based on an input-device profile and an output-device profile, each profile having a tone curve and a color matrix, are provided. In one embodiment, the method includes receiving color data from an input device and determining whether the color data is in a linear space. If it is determined that the color data is not in a linear space, the method further includes applying the tone curve of the input device profile to the color data to convert it into a linear space. The method further includes converting the color(s) associated with the color data from the input linear space to an output linear space by applying the color matrix of the input device profile and the inverse color matrix of the output device profile to create color-converted image data.

摘要： The various methods and systems described herein are directed to supplying a secure channel for software executing on a host computer. The methods and systems address and provide solutions for an attack model in which rogue software executing on the host computer attempts to inappropriately obtain or otherwise manipulate data. Some embodiments can provide pixel data that can be kept confidential (in that untrusted software applications cannot read the data off of the display screen). In addition, other embodiments can preserve the integrity of the pixel data by detecting whether the pixel data has been inappropriately manipulated. Various embodiments are based on a decryption engine that is located on a video card very late in the video processing chain such that programmatic access to decrypted pixel data is denied.

摘要： The present disclosure relates to parsing encrypted content and sending the encrypted content to appropriate stacks of components. Encrypted video content is sent to a video stack and encrypted audio content is sent to an audio stack. Components in either stack may or may not be able to decrypt the encrypted content. A common interface is provided to the components to pass encrypted content and encryption content with one another. Components not able to perform decryption pass on the encrypted content to succeeding components in the stack until a component capable of decrypting the encrypted content receives the encrypted content. Control from a hardware lawyer in a stack may be sent back through the stack using a secure link established by the common interfaces used by the components.

摘要： Accelerating video data decoding is described. In one aspect, hardware accelerated video decoding operations are configured to decode source video data in a first encoded data format. During video data processing operations, the source video data is evaluated to detect any change in the encoding format. Responsive to detecting a change in the source video data encoding, wherein the changed encoding is at least partially incompatible with the first encoded data format, the hardware accelerated video decoding operations are dynamically reconfigured. The reconfigured decoding operations decode the source video data content based on the changed encoded data format.

摘要： Techniques and tools for representing pixel data in a video processing or capture system are described. Described techniques and tools provide efficient color representation for video processing and capture, and provide flexibility for representing colors using different bit precisions and memory layouts. Described techniques and tools include video formats that can be used, for example, in hardware or software for capture, processing, and display purposes. In one aspect, chroma and luma information for a pixel in a video image is represented in a 16-bit fixed-point block of data having an integer and fractional components. Data can be easily converted from one representation to another (e.g., between 16-bit and 10-bit representations). In other aspects, formats for representing 8-, 10- and 16-bit video image data (e.g., packed and hybrid planar formats), and codes for indicating the formats, are described.
