Described is a method and system a system and method for dynamically and intelligently configuring a computer system's video-related settings upon connection of a monitor, and/or reconfiguring upon disconnection. A monitor configuration may include one or more display mechanisms, their video settings, relative positioning, and may include power scheme data. When a monitor is plugged into or unplugged from a computer system, a monitor manager component is notified and determines the current configuration, such as based on monitor identifiers. The current configuration is searched against persisted monitor configurations seeking a match. If previous monitor configuration data is found, the previous monitor configuration is applied. If not an exact match, configuration data is constructed based on similar configuration data that is persisted, or by querying for capabilities and iterating as necessary to find a video mode that the video card and monitor can use.

The invention includes a system and the associated method for decoding multiple video signals. The video signals may be component video, composite video or s-video signals each having multiple portions using a multimode video decoder. A selection stage may combine the multiple video signals and select some of their video signal portions for processing. The selection stage may time-multiplex some of the video signal portions. An analog to digital conversion stage may be shared by the time-multiplexing of the video signals. A decoder stage may decode the various signal portions and provide decoded output video signals. These feature may reduce the overall cost of the system. Various clock signals may be used to operate various stages of a multimode video decoder. Some of the clock signals may run at different frequencies and others may operate at a different phase.

The invention relates to a digital demodulation method and a demodulator for a non-synchronous composite video signal and an S video signal. The method comprises the following steps: a fixed sampling clock is set to collect data for the entire demodulation process; the composite video signal or the S video signal is converted into an initial digital signal; a field-synchronizing signal and a line synchronizing signal in the initial digital signal are restored, and the field frequency and the line frequency in the initial digital signal are calculated and locked; the color intensity in the initial digital signal is demodulated; a line synchronizing phase is secondarily sampled by the interpolation method; the phase is adjusted; the intense color is separated; and the brightness, the contrast degree and the saturation degree are adjusted. By utilizing the invention, the dependence on an analog phase-locked loop in a video demodulator can be eliminated. The phase-locked loop is the important core in the digital video demodulator and is the only one who cannot be separated from the analog. Therefore, in an integrated circuit of the digital video demodulator, not only the reducing of the area and complexity of the integrated circuit is realized, but also the effect brought by using the phase-locked loop is also achieved.

The invention can modulate diaphaneity of PIP. It adopts the RGB style data of main picture and inner picture to be weighting coefficient transformed and outputs them from itself display window. The transformed inner picture is overlapped with main picture and the diaphaneity of the transformed inner picture is set adjustable. The inner picture has different diaphaneity to prevent main picture covered while viewer is watching. The approach works in the following steps: transferring main picture's video signal into RGB style image data that is memorized in main picture memorizer; transferring inner picture's signal into RGB style image data that is dwindled according to inner picture vision's setting proportion and then memorized in inner picture memorizer; transferring inner picture data and overlapping it on main picture data and the overlapped data is output onto the display screen to display the image after being overlapped.

A video signal recording/reproducing apparatus for recording/reproducing a high resolution video signal wherein the video resolution is enhanced by shifting a carrier frequency to a higher band in frequency modulation in a VCR's video signal recording mode, and by differently setting the frequency characteristics depending on the presence of a color signal in the video signal. The video signal recording/reproducing apparatus results in a highly enhanced resolution of a recording/reproducing video signal by determining use of a color signal trap in an equalizing block and a filter frequency for separating a luminance signal depending on the presence of a color signal in recording/reproducing a video signal after determining whether the color signal is present. Also, the video signal recording/reproducing apparatus results in a highly improved resolution of a recording/reproducing video signal by shifting an FM modulation carrier frequency to a higher band and by shifting a peaking frequency in an equalizing block to a higher band.
