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.

Abstract translation: 用于处理图形控制器中的Hsync和Vsync信号的装置和方法，以避免由毛刺引起的脉冲的错误读取。 该装置和方法涉及检测何时第一次同步信号跨越阈值。 当发生这种情况时，即使在该期间内出现跨越阈值的后续转换，也将该检测电路的输出保持预定时间段。 在预定时间段到期后，输出被释放，并且可以采取与此时的输入同步信号相同的状态。 以这种方式，可以避免由同步信号上的毛刺读取“错误”脉冲引起的分辨率格式的误解。

Abstract: In a DVD playback mode only, the first type interface is disabled and a DVD driver unit having a hardware DVD decoder connected to a DVD reader unit arranged to read video data from a DVD inserted therein is powered on. In the described embodiment, the DVD decoder unit is also connected to the display screen by way of a second type interface is powered on. The video data is read from the DVD by the DVD reader unit and sent by the DVD reader unit to the hardware DVD decoder unit which then decodes the video data before passing it directly to a timing controller unit coupled to the display screen by way of the second type interface. The timing controller unit converts the video data at a native resolution to a display screen resolution that is then displayed on the display screen.
