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 The standard was adopted in 2002 and superseded the Generalized Timing Formula.
Early home computers output video to ordinary televisions or composite monitors, utilizing television display standards such as NTSC, PAL or SECAM.These display standards had fixed scan rates, and only used the vertical and horizontal sync pulses embedded in the video signals to ensure synchronization, not to set the actual scan rates.
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 ...
This part of the line display process is the Horizontal Blank. [1] [2] In detail, the Horizontal blanking interval consists of: front porch – blank while still moving right, past the end of the scanline, sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black".
Scanlines on a Mitsubishi CS-40307 CRT color television. The fine dots through the bright scanlines are due to the shadow mask. PAL video signal scan line. From the left: horizontal sync pulse, back porch with color burst, signal itself, front porch, sync pulse, back porch with color burst, video portion of the next scan line.

In electrical engineering terms, for digital logic and data transfer, a synchronous circuit requires a clock signal.A clock signal simply signals the start or end of some time period, often measured in microseconds or nanoseconds, that has an arbitrary relationship to any other system of measurement of the passage of minutes, hours, and days.
