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.

摘要： A data broadcast program TS transmission apparatus outputs a data broadcast program TS transmitted by the local broadcast station having the apparatus in accordance with a data broadcast program TS delivered by a second broadcast station via a network. A judgment list storage block stores a selection list containing data representing whether a received data broadcast program element is to be included in the data broadcast program TS of the local station, a replacing list for replacing the data broadcast program element with a local broadcast station program element prepared by the local broadcast station, etc. A separation judgment block separates a TS packet from the received data broadcast program TS and referencing the selection list, reports to a replacement/synthesis block those to be included in the data broadcast program TS of the local broadcast station. Furthermore, if there is a data broadcast program element to be replaced, the separation judgment block reports it to the replacement/synthesis block. The replacement/synthesis block reads out from the program element storage block a local broadcast station program element which the replacement/ synthesis block has been instructed to replace, generates a TS packet, and outputs it as a local broadcast station data broadcast program TS together with the selected TS packet to a multiplexing apparatus.
