Definitions
- the microprocessor 105 controls the display data generator 106 (for example, a computer graphics adapter) to send a video signal 101, a video signal 102, a video signal 103, and horizontal and vertical synchronizing pulses 104 to the display apparatus 20.
- the display data generator 106 for example, a computer graphics adapter
- the software located in the PC forces the graphics adapter 106 to generate a full white (or red, green, or blue, or any combination) line picture ("burst-line") when a certain command is activated.
- the time during which this line is present is limited to the time required by the WMC 203 located in the monitor 20 to acquire the information so as to be able to generate the window-pulse or control pulse C, as will be explained hereinafter.
- the window enhancement may also comprise MPEG artifact reduction.
- a computer generates coordinates determining a window of display data to be displayed on a monitor.
- One of these coordinates may indicate the starting pixel number in a line where the window starts.
- the computer further generates reference information indicating a time of occurrence and a corresponding running number of a first predetermined pixel, and a time of occurrence and a corresponding running number of a second predetermined pixel of the display data. It is possible to determine, from this reference information, the instant of occurrence of the starting pixel for every running number of this pixel of the window. This has the advantage that the reference information needs to be available once only, while the instants of occurrence of several windows are determined from the coordinates of the windows and this single reference information.
