Abstract: A content reproducing device according to the present invention is provided with (a) a broadcast wave receiving section for receiving a broadcast content together with a sync signal(s) multiplexed on the broadcast content, (b) a sync signal extracting section for reproducing the broadcast content immediately after the broadcast content is received by the broadcast wave receiving section, and (c) a control section for controlling the content reproducing device in accordance with the sync signal in synchronism with the reproduction of the broadcast content.

Abstract: A broadcast data receiving section receives broadcasted broadcast data. A reception confirmation key extracting section extracts reception confirmation keys from the broadcast data. A reception confirmation processing section counts the extracted reception confirmation keys. A viewing determination section determines that a viewer has watched a program when the thus counted number of reception confirmation keys exceeds a reference value. This makes it possible to more accurately determine whether the viewer has watched the program.

Abstract: A character input frame is displayed in a popping-up manner and erased automatically in a position in which an operator desires to effect a handwriting input. A character input frame information generating section generates character input frame information based on coordinate input position information from a coordinate input section, and stores the information in a first storage section. A character recognizing section recognizes a character extracted by a character extracting section, and stores character code data of the result of recognition into a second storage section. A display control section displays in a popping-up manner the character input frame from an initial input position on a display panel based on the character input frame information from the first storage section. The character input frame information generating section erases storage contents of the first storage section based on recognition completion information from the character recognizing section.
