Abstract
For changing setting of caption output format, a TV receiver sequentially outputs, to a monitor; a font setting image having options of two parameters, font type and size, in matrix; a color setting image having options of foreground and background colors in matrix; an edge setting image having options of edge type and color in matrix; and an opacity setting image having options of foreground and background opacities in matrix, and allows user to select the options of each two parameters based on each setting image, and further changes the setting image to be output to the monitor, depending on whether “Transparent” is selected as the foreground and/or background color. The TV receiver excludes, from each setting image, an option combination of two options, one causing loss of discriminability of the other, to make impossible selection of such option combination. The user can quickly complete intended setting without redundant procedures.
