摘要： Implementations of transforms, such as a discrete cosine transform (DCT) and inverse DCT on a graphics processing unit (GPU), use direct matrix multiplication. GPU features such as parallel graphics pipelines, multi-channel capability, and multiple render targets are used to obtain significantly faster processing speeds than on a conventional central processing unit (CPU). Various rendering modes may be used, such as point rendering mode, line rendering mode, and triangle or quadrilateral rendering mode.

摘要： Seek support facilitates convenient access to portions of a media file a user wishes to access. Seek support is provided by a usage model based on prior users' access of a media file or expected user access patterns. The usage model reflects expected next segments a user will seek when accessing the media file. A prefetching model derived from the usage model reduces seeking delay by prefetching one or more expected next segments identified from the usage model that will result in minimal seeking distance. Correspondingly, a method of prefetching segments also facilitates access to the media file. A quantity of segments of a media file to be prefetched and a current region of a media file being access are identified. At least one next segment identified by the prefetching model as an expected next seeking destination from the current region is identified, and the next segment is prefetched.
摘要翻译：寻求支持便于方便地访问用户希望访问的媒体文件的部分。寻求支持由基于用户访问媒体文件或预期用户访问模式的使用模型提供。使用模式反映了用户在访问媒体文件时将寻求的预期下一个细分。从使用模型导出的预取模型通过预取从使用模型识别的一个或多个预期的下一个段来减少寻求延迟，这将导致最小寻找距离。相应地，预取片段的方法也有利于对媒体文件的访问。识别要预取的媒体文件的片段数量和正在访问的媒体文件的当前区域。识别由预取模型识别为来自当前区域的期望的下一个寻找目的地的至少一个下一个段，并且预取下一个段。

摘要： System and methods for range and cover queries in overlay networks are described. In one aspect, respective node intervals [s, t] of multiple node intervals are allocated to corresponding nodes in a segment tree. Each integer s and t corresponding to an index to a sorted array of possible endpoints of the node intervals. Each node in the segment tree corresponds to a particular computing device (peer) of multiple computing devices in an overlay network. A node interval [s, t] is assigned to a particular peer associated with a key. This assignment provides a connection between node interval structural information of the segment tree and an underlying structure-less routing substrate in the overlay network. The segment tree is distributed across the peers for query operations over DHT.

摘要： Systems and methods are described for mobile device collaboration. An exemplary collaborative architecture enables aggregation of resources across two or more mobile devices, in such a manner that the aggregation of resources is practical even considering the miniaturized and limited battery power of most mobile devices. In a video implementation, the exemplary collaborative architecture senses when another mobile device is in close enough proximity to aggregate resources. The collaborative architecture applies an adaptive video decoder so that each mobile device can participate in playing back a larger and higher-resolution video across combined display screens than any single mobile device could playback alone. A cross-display motion prediction technique saves battery power by balancing the amount of collaborative communication between devices against the local processing that each device performs to display visual motion across the boundary separating displays.

摘要： Systems and methods for automatically inserting advertisements into source video content playback streams are described. In one aspect, the systems and methods communicate a source video content playback stream to a video player to present source video to a user. During playback of the source video, and in response to receipt of a request from the user to navigate portions of the source video (e.g., a user command to fast forward the source video, rewind the source video, or other action), the systems and methods dynamically define a video advertisement clip insertion point (e.g., and insertion point based on a current playback position). The systems and methods then insert a contextually relevant and/or targeted video advertisement clip into the playback stream for presentation to the user.
