Computer text and ordinary images displayed together without text jitter. Scan converter enables superposition of alphanumerical text generated by computer-driven video generator on National Television System Committee (NTSC) standard interlaced-scan image. Made of commercially available integrated circuits and operates in conjunction with NTSC synchronizing-signal generator. Standard television picture transmitted in two interlaced fields. Without scan converter, text image moves up and down by one line as fields change. With scan converter, text image stands still.
