A library to capture and decode vertical blanking interval data
The Zapping VBI library, in short ZVBI, provides functions to capture and decode VBI data. The vertical blanking interval (VBI) is an interval in a television signal that temporarily suspends transmission of the signal before next screen field begins. The VBI can be used to carry data, since anything sent during the VBI would naturally not be displayed. This includes Closed Captions, Teletext, VPS, WSS, and XDS.
