Displaying a stream of video data on a display device may be performed by decoding a portion of the video data to form a video frame. A queue time is determined when the video frame should be displayed. The queue time is adjusted by a margin time relative to a next display time to compensate for interrupt jitter, wherein the margin time is less than a period of time between periodic display time events and is larger than a specified interrupt jitter time. A software interrupt event is set to occur corresponding to the adjusted queue time. The video frame is queued in response to occurrence of the software interrupt. The queued video frame is transferred to a display buffer for the display device upon the occurrence of a next display time event after the occurrence of the software interrupt.

Jitter cancellation for audio/video synchronization in a non-real time operating system

A system comprising a storage including an image file associated with a plurality of pixels and processing logic coupled to the storage. The processing logic is adapted to determine an average of least significant bits associated with a maximum of two of the plurality of pixels, add the average to bits associated with a target pixel, and disassociate from the target pixel least significant bits of the target pixel. No pixels are disposed between the target pixel and each of the two of the plurality of pixels.

Techniques for efficient dithering

Combining a graphics object with a picture where only the luminance value of a graphics object pixel is written to a corresponding picture pixel if the chrominance values of the graphics object pixel indicate transparency and yet the luminance value indicates non-transparency.

Method and system to combine a digital graphics object and a digital picture

Image resizing through resampling by poly-phase filtering with a phase generation from input parameters but with lower resolution of the phase for filter selection. Field and frame mode selection creates initial offsets for alignment. A phase accumulator generates sample addressing with its most significant bits, generates filter selection with its middle bits, and maintains its least significant bits for accuracy.
