Abstract: Various embodiments utilize hardware-enforced boundaries to provide various aspects of digital rights management or DRM in an open computing environment. Against the backdrop of these hardware-enforced boundaries, DRM provisioning techniques are employed to provision such things as keys and DRM software code in a secure and robust way. Further, at least some embodiments utilize secure time provisioning techniques to provision time to the computing environment, as well as techniques that provide for robustly secure storage.

Abstract: Systems and/or methods are described that enable multi-threaded multimedia processing. These systems and/or methods may, in some embodiments, allocate threads for components of a multimedia pipeline based on input/output characteristics of the components. These systems and/or methods may also allocate threads and priorities for those threads based on a relative importance given components of two or more multimedia pipelines.

Abstract: Techniques for playing a media file in a multimedia application include launching a multimedia application as one process and automatically launching a pipeline of one or more media processing components as one or more isolated processes. In this manner, any untrustworthy components can be executed in an isolated process that is separate from the execution process of the multimedia application, thereby improving fault tolerance and hang resistance.

Abstract: Systems and methods for midstream determination of varying available bandwidth for streaming content between two network entities are described. During content streaming, a client requests a server to surge the content transmission rate. One or more bandwidth measurements are taken during the surge to determine if the increased transmission rate can be adequately managed. If the increased transmission rate can be adequately managed, the client may request the server to transmit remaining content at a transmission rate that is not greater than the increased, or surged, transmission rate. In a multi-bitrate file scenario, the surge rate may be higher than the rate of the fastest useable stream. In such a case, the fastest useable stream is selected. If the increased transmission rate is not suitable for future transmission, then the rate may remain at the original transmission rate.

Abstract translation: 描述了用于中间流确定两个网络实体之间的流内容的可变带宽的系统和方法。 在内容流传输期间，客户端请求服务器浪费内容传输速率。 在浪涌期间进行一个或多个带宽测量，以确定是否可以充分地管理增加的传输速率。 如果可以适当地管理增加的传输速率，则客户端可以请求服务器以不大于增加或激增的传输速率的传输速率发送剩余内容。 在多比特率文件场景中，浪涌速率可能高于最快可用流的速率。 在这种情况下，选择最快的可用流。 如果增加的传输速率不适合将来传输，则速率可能保持在原始传输速率。

Abstract: A distributed media session is described, which when executed, resolves a distributed topology from a request to stream data from a source device to a client device over a network. The distributed topology references a plurality of software components that, when executed, fulfill the request. At least one of the plurality of software components is executable on each of the source device and the client device.

Abstract: Methods and systems enable content authors to achieve frame-accurate editing and, in at least some embodiments, reduce the amount of content that needs to be decompressed in order to operate on the frames. Some embodiments ensure that bit rate integrity is preserved so that bit rate conditions associated with streaming environments are preserved. Various embodiments intelligently determine which content portions should be decompressed, processed, and recompressed and which content portions should not be decompressed.

Abstract: A request is received to play compressed video data in a reverse direction. A process identifies a most recent key frame received and decodes the most recent key frame. The process then identifies delta frames received after the most recent key frame and decodes these identified delta frames. The decoded delta frames are then played in the reverse direction. Additionally, compressed audio data can be decoded and played in the reverse direction along with the video data.

Abstract: Strategies for automatically selecting the most appropriate processing pipeline (or runtime) for a particular data item are described. In one embodiment, a media playing application automatically selects the most appropriate media processing pipeline for a media data item from multiple available processing pipelines, or candidates. In this regard, the application makes this selection by utilizing heuristic techniques to identify which available pipeline provides the most enhanced playback experience to a user with respect to certain attributes such as supported playback features and security. These heuristic techniques can take one or more criteria into account and can be implemented in any suitable way. By way of example and not limitation, in one embodiment, a selection process is used wherein potential pipeline candidates are ordered and sequentially evaluated.

Abstract: Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.

Abstract translation: 技术能够为数字内容创建预览许可。 在某些情况下，预览许可证表示允许内容消耗设备消耗的内容少于所有内容。 该预览许可证可以创建指定内容消费设备可能消耗的数字内容的多个部分的列表。 这些技术还可以向设备用户提供购买在消费预览许可部分之后消费所有数字内容的权利的提议。 在其他情况下，内容服务器可以将预览许可嵌入到包含数字内容的内容包中，允许服务器将包分发到多个设备。 在其他情况下，预览许可证可能会绑定到域而不是单个设备。 这允许成员设备共享数字内容和预览许可，使得每个成员设备可以享受预览体验。
