Description: Perl interface to the "ZVBI" VBI device capture library
 Using the ZVBI library, this Perl module provides object-oriented
 interfaces for (from lowest to highest level of abstraction) accessing
 raw VBI sampling devices (currently the Linux V4L & V4L2 API and the
 FreeBSD, OpenBSD, NetBSD and BSDi bktr driver API are supported),
 a versatile raw VBI bit slicer, decoders for various data services
 and basic search, and render and export functions for teletext pages.
