Hardware-based system, method, and computer program product for synchronizing stereo signals

A method for synchronizing an input data stream with an output data stream in a video processor. The method includes receiving an input data stream and receiving an output data stream, wherein the input data stream and the output data stream each comprise a plurality of pixels. The method further includes sequentially storing pixels of the input data stream using an input buffer and sequentially storing pixels of the output data stream using an output buffer. Timing information is determined by examining the input data stream and the output data stream. A synchronization adjustment is applied to the input buffer and the output buffer in accordance with the timing information. Pixels are output from the input buffer and the output buffer to produce a synchronized mixed video output stream.

Synchronization of video input data streams and video output data streams

Disclosed are an apparatus, a computer device, a system, computer readable media and a method for using graphics processing unit ('GPU')-generated data to characterize, in-situ, the ability of a cable to reliably carry digitized video, among other things. In one embodiment, a computing device includes a processor coupled via a system bus to a graphics engine and a video cable-testing apparatus. This apparatus has an input port configured to couple to the digitized video cable to receive pixel data generated by the graphics engine. It also has a signal integrity evaluator ('SIE') configured to identify the digitized video cable as the source an amount of data corruption, the amount of data corruption being a function of the pixel data. The signal integrity evaluator includes a classifier to classify the amount of data corruption into classes that each represents various degrees of degradation of the computer-generated video images.

Using graphics processing unit ('GPU')-generated data in-situ to characterize the ability of a cable to carry digitized video

Disclosed are a GPU video data preprocessor, a computer device, an apparatus and a method for facilitating expeditious video transfer to graphics memory for enhancing display and video capture applications, among other things. In one embodiment, a graphics preprocessor is used to preprocess video for transit via a graphics processing unit ('GPU') directly to graphics memory without invoking a graphics driver. The graphics preprocessor includes an input configured to receive video data. It also includes a native data formatter coupled to the input and configured to format the video data as GPU data to conform with the architecture of the GPU. In at least one embodiment, the graphics preprocessor also includes a command execution unit, which can be configured to transmit an instruction executable by the GPU as a transmitted instruction to perform a graphics pipeline operation on the GPU data.
