The Horita KCT-50 is a stand alone video character generator that works with a standard PS2- type PC keyboard to add titles and captions to your SD NTSC RS-170A/PAL 625/50 analog composite video. The KCT-50 can add up to nine lines of 20 characters each, and the best part is no PC or PC software is required! In addition, the KCT-50 also includes a battery backed up clock/calendar which can overlay your video with a variety of formats of time and date displays to accompany the text.
