    摘要： Described is an adaptive scheduler associated with a desktop window manager that dynamically controls the rate at which graphics frames are composed. Values corresponding to performance when composing a frame are measured, and the frame composition rate is adjusted as necessary based on the values. The measured data is sampled to provide smooth adjustments. The sampled data is evaluated as to whether the current frame rate is too slow, too fast, or acceptable. If too slow, the frame rate may increased relative to the refresh rate, while if too fast, the frame rate is decreased relative to the refresh rate. In one implementation, the frame rate is too fast if a count of missed frames achieves a missed threshold value, or if a count of late frames achieves a late threshold value. The frame rate is too slow if a count of early frames exceeds an early threshold value.

    摘要： Methods, systems and architectures for processing renderable digital content are described. The various embodiments can protect against unauthorized access or duplication of unprotected content (i.e. decrypted content) once the content has reached a rendering device such as a user's computer. A flexible framework includes an architecture that allows for general media sources to provide virtually any type of multimedia content to any suitably configured rendering device. Content can be protected and rendered locally and/or across networks such as the Internet. The various embodiments can provide a standard platform that can that can be leveraged to protect content across a wide variety of rendering environments, content types, and DRM techniques.

    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： Methods, systems, and computer program products for arbitrarily indexing multimedia content. In accordance with example embodiments, a multimedia content stream that comprises one or more samples is received. At least one of the samples is passed to one or more multimedia filters for analysis based on criteria that define an index type for the multimedia filter. Once it is determined that the sample meets the criteria for an arbitrary filter and index type, an index entry that identifies both the sample and the index type of the arbitrary filter is created. The index entry is adapted in accordance with a common, extensible indexing scheme to coexist with other index entries of other or the same index type for the sample. The created index entry is stored for subsequent access.

    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： Provided is a computer-implemented method in which cameras at a live event can be remotely controlled by a user device having one or more processors and memory storing one or more programs for execution by the one or more processor. The user device obtains a wireless transmission of a camera view of a live event from each of a plurality of video cameras at the live event. At least a subset of views from the plurality of cameras is displayed on the user device. The user device obtains instructions from the user directing movement of a first video camera of the plurality of video cameras. The user instructions are converted into one or more actuator commands and are wirelessly transmitted to the first video camera for changing the camera view of the live event of the first video camera.

    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.
