The parameters defined by standard include horizontal blanking and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync polarity. The standard was adopted in 2002 and superseded the Generalized Timing Formula.
Generalized Timing Formula is a standard by VESA which defines exact parameters of the component video signal for analogue VGA display interface.. The video parameters defined by the standard include horizontal blanking (retrace) and vertical blanking intervals, horizontal frequency and vertical frequency (collectively, pixel clock rate or video signal bandwidth), and horizontal/vertical sync ...

Vertical synchronization or Vsync can refer to: Analog television#Vertical synchronization, a process in which a pulse signal separates analog video fields; Screen tearing#Vertical synchronization, a process in which digital graphics rendering syncs to match up with a display's refresh rate; Vsync (library), a software library written in C# for ...

Horizontal Sync (HSYNC) This is a special signal that goes from the camera sensor or ISP to the camera interface. An HSYNC indicates that one line of the frame is transmitted. Vertical Sync (VSYNC) This signal is transmitted after the entire frame is transferred. This signal is often a way to indicate that one entire frame is transmitted.

While there are simple methods to produce somewhat satisfactory progressive frames from the interlaced image, for example by doubling the lines of one field and omitting the other (halving vertical resolution), or anti-aliasing the image in the vertical axis to hide some of the combing, there are sometimes methods of producing results far ...
