摘要： A broadcast reception apparatus is provided with a reception unit for receiving broadcast data as a transport stream. The transport stream includes video data and a plurality of navigation information sequences. Each navigation information sequence includes navigation information which includes graphics data to be combined with the video data for display. A TS (Transport Stream) decoder unit extracts the video data and navigation information from the transport stream. A reception control unit controls the TS decoder unit so that the TS decoder unit extracts navigation information from a navigation information sequence which is suitable for the the broadcast reception apparatus. A navigation information storage unit stores the navigation information extracted by the TS decoder unit. A reproduction control unit combines graphics data included in the navigation information stored in the navigation information storage unit with the video data extracted by the TS decoder unit and displays a composite image of this combination. This achieves a broadcast reception apparatus which selectively uses necessary pieces of navigation information to display an image as a user interface.
