An installation guide and more can be found in the github wiki.

About

This program takes a set of teletext page files and generates a feature rich transmission stream on stdout.

The transmission stream can be piped to raspi-teletext or any other application that needs a teletext packet stream. It is a console application that can be compiled for Raspberry Pi or Windows.

It generates a T42 teletext stream that can be piped to raspi-teletext to add a teletext signal to the Raspberry Pi composite output, vbit-py to drive a Vbit teletext inserter board, or into the vbit-iv in-vision renderer.

VBIT2 can also optionally generate output a Packetized Elementary Stream for insertion into an MPEG transport stream for DVB teletext.
