RECEIVING DEVICE FOR RECEIVING VIDEO AND TELETEXT SIGNALS

摘要

According to the invention, the analog-to-digital converter (24) which is provided for processing teletext signals is used for two purposes. During time slots in which no sync signal or teletext signal is separated from the video input signal (CVBS), the analog-to-digital converter (24) is used for other tasks, for example, for querying keyboard entries of an operator control unit (30).
