The described technology addresses one or more of the foregoing problems by receiving one or more workloads from an application. Each of the one or more graphics workloads are associated with completion deadline information and execution metadata representing execution guidance for the workload. The described technology further generates a processor performance adjustment for each of the one or more workloads using a performance model providing the processor performance adjustment based on the completion deadline information and the execution metadata for each of the one or more workloads. The described technology further communicates each of the one or more received workloads and its corresponding generated processor performance adjustment to a processor subsystem. Each of the processor performance adjustments instructs the processor subsystem on a processor adjustment to be implemented when executing the associated workload.

Dynamic processor power management

Innovations in the area of hardware-protected digital rights management ('DRM') systems are presented. For example, a hardware-protected DRM system includes a trusted layer and untrusted layer. In the untrusted layer, a control module receives source media data that includes encrypted media data. The control module processes metadata about the media data. The metadata, possibly exposed by a module in the trusted layer, is not opaque within the untrusted layer. In the trusted layer, using key data, a module decrypts encrypted media data, which can be the encrypted media data from the source media data or a transcripted version thereof. A module in the trusted layer decodes the decrypted media data. A host decoder in the untrusted layer uses the metadata to manage at least some aspects of the decoding, rendering and display in the trusted layer, without exposure of decrypted media data or key data within the untrusted layer.

Media decoding control with hardware-protected digital rights management

A computer-implemented system is provided that facilitates implementation of a voice over IP (VOIP) application. The system includes a host system and a user interface (UI) host process residing on the host system. The system also includes an agent host process residing on the host system which is being configured to process a VOIP call received by one or more VOIP applications executable on the host system. The agent host process running as a foreground or background process for the duration of the VOIP call to (i) communicate with a VOIP server associated with the VOIP application, (ii) capture content from at least one input device associated with the host system and (iii) render content on an output device associated with the host system when an instance of the UI host process operates in the foreground.

Voice-over-internet protocol (VOIP) application platform

A computer-implemented system is provided that facilitates implementation of a voice-over-IP (VOIP) application. The system includes a host system and a user interface (UI) host process residing on the host system. The system also includes an agent host process residing on the host system which is being configured to process a VOIP call received by one or more VOIP applications executable on the host system. A moniker protocol is utilized for redirection of input and output between a media element which is utilized to render media on a display on the system. The redirection enables media processing to be allocated between the UI host process in the foreground and the agent host process in the background to thereby reduce latency perceived by a user during a VOIP experience.

Cross-process media handling in a voice-over-internet protocol (VOIP) application platform

In a low-power device a runtime hands video capture and other markup language video objects to a video service, which renders them onto a shared surface. An application-specific compositor manipulates the shared surface, e.g., by texture wrapping or animation. A system compositor composites the manipulated shared surface with other data, such as rendered frames from other application-specific compositors and/or computer generated text. The device then displays the attendant rendered, manipulated, and composited video frames. In some cases, only a single copy of the shared surface is utilized. When the video object's shape, alignment, and opacity satisfy predetermined criteria, the video service renders the video object onto the shared surface using a hardware scaler; otherwise, rendering is done without using the hardware scaler.

Shared surface hardware-sensitive composited video

Embodiments are configured to provide information for display. Various embodiments include processing functionality that can be used to efficiently process pixel data associated with video, graphical, and other information. The functionality can be used in conjunction with different hardware and/or software architectures and configurations. In an embodiment, a computing device includes functionality to use a distinct window having alpha and occlusion features that can be used when processing pixel data associated with user interface (UI) elements and video, but is not so limited. The computing device can use the distinct window to display user interface elements having different levels or amounts of transparency as part of video capture and playback operations.
