Video data playback for magnetic tape recorder - has shift registers or addressable memories for decoding pulse frequency modulated bit series

摘要

Playback arrangement for information stored on magnetic tape of cassette recorder displayed in readable form has shift registers or addressable memories. The digital signals are recorded in pulse frequency modulated bit series. They are serially read out via a frequency demodulator and stored in a shift register or an addressable memory with bit parallel outputs for one or more code words. The code word is output as the address signal and input in a second shift register or memory. The drive of the magnetic tape is stopped by means of a signal emitted by an evaluator via an electronic switch.
