VBI stands for Vertical Blanking Interval, a gap between the image
data transmitted in an analog video signal. This gap is used to
transmit AM modulated data for various data services like Teletext
and Closed Caption.
The zvbi library provides routines to read from raw VBI sampling
devices, to demodulate raw to sliced VBI data, and to interpret
the data of several popular services. It has been written for
the Zapping TV viewer <http://zapping.sourceforge.net>.
For installation details see the file INSTALL. Information for
application writers is available in the doc and test directories.
Send ideas, questions and bug reports to
<mailto:zapping-misc@lists.sourceforge.net>, registration is not
required.
