The combined picture signal, including vertical and horizontal blanking and synchronizing signals. The remainder (the vertical blanking interval) allow for vertical synchronization and retrace. In PAL and NTSC, the vertical sync pulse occurs within the vertical blanking interval. When in HS mode, commands are transmitted during the vertical blanking interval. Like teletext, this signal is also broadcast in the vertical blanking interval. Most VCR circuits use the amplitude of the vertical blanking pulse to operate the AGC. This happens during the blanking interval. Doing so outside of the vertical blanking interval can allegedly damage the hardware. For monopulse radar, signal processing is identical for the main lobe and sidelobe blanking channels. This was the Bearcats' first shutout since blanking the Redhawks in 2013. Other applications include blanking dies, forging dies, and industrial blades. A misfeed can occur when the metal strip is fed through the blanking machine. Sometimes editors commit vandalism by removing content or entirely blanking a given page. The sockets have blanking devices to prevent accidental contacts. This was the basis for an operating system service called the "VBL ("vertical blanking") Manager".
