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. The zvbi library provides functions to read from Linux V4L, V4L2 and FreeBSD BKTR raw VBI capture devices, from Linux DVB devices and from a VBI proxy to share V4L and V4L2 VBI devices between multiple applications. It can demodulate raw to sliced VBI data in software, with support for a wide range of formats, has functions to decode several popular services including Teletext and Closed Caption, a Teletext cache with search function, various text export and rendering functions. Basically zvbi offers all functions needed by VBI applications except for the user interface. The library was written for the Zapping TV viewer http://zapping.sourceforge.net. TODO: Needs to be tested on hardware -- send success/failure reports to pkgsrc-wip-discuss@lists or thomasklausner@users.
