Systems and methods are described for monitoring the activity of an object to aid in debugging a problem with an application using the object. An operating system registry is altered to reference a proxy object when the application attempts to reference the object. The proxy object exposes an interface exposed by the object. Communications passing between the application and the object can be monitored in the proxy object. The proxy object can be monitored locally or remotely through a remote procedure channel.

Systems, methods, and computer program products for parsing a packetized, multi-program transport stream are disclosed. A packetized, multi-program transport stream is received in a demultiplexer. Program specific information is extracted from the program stream and displayed on a user interface. A user may select a program from the program stream for further processing. The user interface generates a signal indicative of the selected program, and the demultiplexer output is configured based on the selection signal.

The described embodiments relate to testing streaming media capture devices and/or computer systems. One exemplary method enumerates and tests multiple streaming media capture device which are operably associated with a computer. The method simultaneously exercises said computer's display and power states.

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.

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.

Techniques for simulating universal serial bus (USB) video devices are described. In one example, a document containing a USB video device descriptor set is loaded by a device simulator application. The document is parsed and the descriptor set is extracted. The descriptor set is then used to define a simulated USB video device. A device simulation framework simulates a USB device attachment to a computing device and video data is streamed from the simulated USB video device to the computing device. A video driver associated with the computing device processes the video data as if the data originated from USB video device hardware. Multiple different USB video devices may be simulated and different collections and configurations of video data can be utilized.
