Abstract
In a display apparatus (PI) displaying a closed-caption (Scc, DS) multiplexed in the first and second component video signals (Scv1: Y, PB, and PR, Svc2: Y and C) received from externally provided video signal sources, a video signal selector (7) selects one of said first and second component video signals (Scv1, Scv2); a closed-caption extractor (3) extracts the closed-caption (Scc, DS) from said selected one of first and second component video signals (Scv1, Scv2); and a controller (10) controls the closed-caption extractor (3) based on the format type of the selected first and second component video signals (Scv1 and Scv2).
