Abstract
A broadcast receiving device which clearly indicates supplementary information transmitted along with broadcast content, and which facilitates program search. The supplementary information may be a program sequence information of a digital broadcast. Plural types of topic information related to a broadcast content description and a genre of a broadcast content are designed in the supplementary information. A memory device stores, separately for each genre, a display priority degree for each of the plural types of topic information. A control processor obtains genre information and topic information items from an acquired supplementary information. The control processor indicates the topic information items on a display according to the display priority degrees stored in the memory device corresponding to the obtained genre information. When indicating a search screen image, the topic information items are extracted from the supplementary information as search keywords and indicated to the user in the screen image.
