Abstract: A multi-function display controller that includes a source detector unit for determining if the source of an input stream is either film originated source originated or video source originated. A source converter unit for converting the input image stream to a common signal processing format is coupled to the source detector unit. Once converted to the common signal processing format, a determination is made if the input image stream is interlaced or non-interlaced (progressive scan). If the input image stream is interlaced, a de-interlace unit converts the interlaced signal to progressive scan using either motion adaptive or motion compensated de-interlacing techniques. It should be noted that in the described embodiment, motion vectors generated for use by the motion compensated de-interlace can be optionally stored in a memory unit for use in subsequent operations, such as motion compensated frame rate conversion or noise reduction (if any).

Abstract: An apparatus and method for processing Hsync and Vsync signals in graphic controllers to avoid a false reading of pulses caused by glitches. The apparatus and method involve detecting when the synch signal crosses the threshold for the first time. When this occurs, the output of the detection circuit is held for the predetermined period of time, even if subsequent transitions across threshold occur during this period. After the predetermined period expires, the output is released and may assume the same state as the input sync signal at that time. In this manner, a misinterpretation of the resolution format caused by the reading of a “false” pulse caused by a glitch on a sync signal can be avoided.
