Abstract

2.1 In a video recorder with built-in teletext decoder, teletext is to be recorded in such a manner that it is possible to replay the teletext signal in several grey steps and also in colour. 2.2 The analog text signal obtained in the teletext decoder (10) is matrixed to form a grey-scale signal (Yg) which is supplied to the recording path (7) via a switch (S1, S2). 2.3 Especially a VHS video recorder including recording of a teletext signal for persons with hearing defects. <IMAGE>
