While not containing any picture data this space is still used to transmit test signals and data for various services like Teletext, Closed Caption and interactive TV. The zvbi library provides routines to read from raw VBI capture devices, to demodulate raw into sliced VBI data, and to interpret the data of several popular services. 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. For details on using the library see the documentation in doc/html (built only if you have Doxygen http://www.doxygen.org/) and the files in the test directory. Download ======== The latest version, sources and RPMs, is available from http://zapping.sourceforge.net. Debian packages are maintained by Christian Marillat, see distribution testing/unstable. Installation ============ To build and install type "./configure" and "make install". For additional instructions see the INSTALL file. The library has been tested on Linux and FreeBSD. Ideas, questions, patches and bug reports ========================================= http://sourceforge.net/tracker/?group_id=2599 or by e-mail mailto:zapping-misc@lists.sourceforge.net, registration is not required.
