Analog television Structure of a video signal The front porch is a brief (about 1. 5 microsecond) period inserted between the end of each transmitted line of picture and the leading edge of the next line sync pulse. Its purpose was to allow voltage levels to stabilise in older televisions, preventing interference between picture lines. The front porch is the first component of the horizontal blanking interval which also contains the horizontal sync pulse and the back porch. 1 https: //store. theartofservice. com/the-blanking-interval-toolkit. html
Analog television Vertical synchronization 1 Vertical synchronization (Also vertical sync or VSYNC) separates the video fields. In PAL and NTSC, the vertical sync pulse occurs within the vertical blanking interval. The vertical sync pulses are made by prolonging the length of HSYNC pulses through almost the entire length of the scan line. https: //store. theartofservice. com/the-blanking-interval-toolkit. html

Seven-segment display - Implementations 1 To operate any particular segment of any digit, the controlling integrated circuit would turn on the cathode driver for the selected digit, and the anode drivers for the desired segments; then after a short blanking interval the next digit would be selected and new segments lit, in a sequential fashion https: //store. theartofservice. com/the-blanking-interval-toolkit. html
Macintosh 128 K - Processor and memory The 68000 and video controller take turns accessing DRAM every four CPU cycles during display of the frame buffer, while the 68000 has unrestricted access to DRAM during vertical and horizontal blanking intervals. Such an arrangement reduces the overall performance of the CPU as much as 35% for most codes as the display logic often blocks the CPU's access to RAM. This made the machine appear to run slower than several of its competitors, despite the nominally high clock rate. 1 https: //store. theartofservice. com/the-blanking-interval-toolkit. html
