Abstract

The present invention relates to an extraction device (12) at a system (10) for flexible distribution of teletext information. The extraction device (12) can be run to, from an analog and/or digital TV-source (14), separate teletext information (D), TV-signal(s) without teletext information (B) and subtitling (C).
