It is written in plain ANSI C with few dependencies on other +tools and libraries, licensed under GPL. + +The vertical blanking interval (VBI) is an interval in a television signal +that temporarily suspends transmission of the signal for the electron gun to +move back up to the first line of the television screen to trace the next +screen field. + +The vertical blanking interval can be used to carry data, since anything sent +during the VBI would naturally not be displayed; various test signals, closed +captioning, and other digital data can be sent during this time period. |
