A streaming video interface component receives video frames from a streaming driver before the frames are received by a consuming application. The streaming video interface component provides the video frames to a video effect rendering component which renders video effects selected by a user. The video frames with the rendered video effects are then provided back to the streaming interface component which thereafter provides them to the consuming application.

Adding video effects for video enabled applications

A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

Accelerated video encoding

A system, device, and method for virtually connecting a media device to a computing device are disclosed. One embodiment comprises a method to operate a virtual media device in a computing device, wherein the virtual media device that is controlled by a remote media device. In this manner, a computing device may stream media data to and from the remote media device.

Virtual media device

A vertical blanking interval (VBI) signal testing tool captures, isolates, and analyzes a VBI signal to determine the quality of the VBI signal or signal source. A digitized VBI signal may be received and analyzed according to industry standards. The VBI signal is examined using thresholds, threshold points, and other points as a way of discerning waveforms in the signal and their individual characteristics. Thereafter, deviations of the VBI signal from industry standards are logged or displayed for review. One feature of the tool records captured VBI data to a persistent storage medium, thereby allowing post-processing of the VBI signal at another time and/or another location. An exemplary analysis program can read the recorded VBI data from the persistent storage medium and perform tests to determine the quality of the VBI signal or signal source. VBI signal translations are also contemplated.

Portable vertical blanking interval signal

A vertical blanking interval (VBI) signal testing tool captures, isolates, and analyzes a VBI signal to determine the quality of the VBI signal or signal source. A digitized VBI signal is received and analyzed according to industry standards. The VBI signal is first examined using thresholds, threshold points, and other points as a way of discerning waveforms in the signal and their individual characteristics. Thereafter, deviations of the VBI signal from industry standards are logged or displayed for review.

Testing a vertical blanking interval signal

A component, such as a Component Object Model (COM) object, operates as an intermediary between an Application Programming Interface (API) extension or plug-in and a driver. The component allows additional objects to be aggregated onto the component, and/or sets one or more setting values for a received request so that an I/O call associated with the request can be completed in a manner that is compatible with other I/O calls. The component may also return, in response to a particular request, a stream index associated with the component.
