Abstract

In case the digital broadcasting wave contains printable contents data, the invention multiplexes a message, a mark or an icon on the display screen of the currently viewed program or outputs an audio message to inform the user of the presence of such contents data. The invention prevents a situation where the contents data cannot be or are not printed even though the data are transmitted, and allows the user to correctly prepare the type or number of sheets in advance in the printer.
