发明名称 Apparatus for processing video signals at the time of a special reproduction mode.
摘要 <p>A video signal processing apparatus for processing a video signal at the time of a special reproduction mode comprises an AID converter (13) for converting a reproduced video signal obtained by demodulating a frequency modulated signal reproduced from a recording medium during the special reproduction mode into a first digital video signal, a memory (19) having a memory capacity for at least storing the first digital video signal corresponding to one field, a switching circuit (14) for selectively producing the first digital video signal or a second digital video signal read out from the memory, a first circuit (15) for at least generating a first pulse signal having a pulse width corresponding to a predetermined time period and a second pulse signal which determines the read-out timing of the memory, a second circuit (18) for generating a control signal based on the first and second pulse signals for controlling read-out from the memory and causing the switching circuit to selectively produce the second digital video signal during a time period approximately corresponding to the predetermined time period, and a D/A converter (21) for obtaining a reproduced composite video signal from the output digital video signal of the switching circuit.</p>
