A content editing apparatus that edits digital broadcast content that is composed of a plurality of data carousels for realizing pseudo-interaction is provided. An operation reception unit receives identification information and a transmission start time and a transmission end time of each module that constitutes a data carousel from an operator. A control unit stores the received information as module information into a module information storage unit. A data carousel definition unit sorts each transmission start time and transmission end time included in the module information, defines a carousel time period of each data carousel based on the sorted times, and selects modules to be transmitted during each carousel time period.

Content editing apparatus, content editing method, content editing program, and computer-readable storage medium

A digital broadcasting system includes an authoring apparatus and a transmission apparatus. The authoring apparatus generates event information, which defines an event message that should be transmitted immediately after an operator's instruction to transmit the event message is received, and adds the event information to a content. The authoring apparatus then extracts the event information from the content by referring to tag information and transfers the extracted event information to the transmission apparatus. The transmission apparatus stores the event message defined by the event information transferred from the authoring apparatus. According to an operator's instruction to transmit the event message, the transmission apparatus issues the event message, and multiplexes and transmits the issued event message and the content.

Digital broadcasting system and event message transmission method

A data broadcast content generation system stores body data for displaying a body page, a plurality of sets of part data each being composed of display element data for determining a display element and attached data for displaying an attached page, and schedule information which associates each broadcast data slot with a set of part data. For each broadcast time slot, the body data, display element data of the set of part data, and attached data of the set of part data are related to each other, so that a display element determined by the display element data will be displayed in the body page and a link destination of the display element will be an attached page displayed using the attached data. The body data, the display element data, and the attached data are then set as carousel data to be transmitted during the broadcast time slot.

Data broadcast content generation system

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.
