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 display control apparatus receives a digital broadcast and compares the present time with a time indicated in a Time_Event_Part provided in navigation information used to control the display of the multimedia data composing a broadcast program. When the indicated time has been reached, the data display control apparatus executes instructions to control the display of the multimedia data.
摘要:
A broadcasting system which includes a broadcasting apparatus and a reception apparatus and which achieves interactiveness using a broadcast wave. The broadcasting apparatus includes a content storing unit for storing the plurality of contents, each content including a set of video data and a set of control information that indicates another content that is a link destination for a present content, and a transmitting unit for multiplexing a set of video data and a plurality of sets of the same control information included in a same content as the set of video data, and for transmitting the multiplexed sets of video data and control information. The reception apparatus includes an extracting unit for extracting a set of video data and a set of control information in a same content as the set of video data, a storing unit for storing the extracted set of control information, a reproducing unit for reproducing the extracted set of video data and outputting an image signal, an operation unit for receiving a user operation that indicates a content switching, and a control unit for controlling the extracting unit to extract another content indicated by the set of control information stored in the storing unit, in accordance with the user operation.

摘要:
A terminal apparatus for interactively switching pieces of presentation data in a system which repeatedly broadcasts pieces of presentation data and corresponding pieces of navigation data including a receiver for receiving the presentation data, a reproduction apparatus, and a cache storage for storing pre-received pieces of presentation data and navigation data. Navigation data is analyzed to detect pieces of link-target presentation data which are presented to an operator. When the operator selects one of the link-target presentation data stored in the cache storage, the reproduction apparatus reproduces the presentation data.
摘要:
A terminal apparatus is provided for displaying an image by reproducing a piece of image information and for interactively changing the image using navigation information. The image is a moving picture, a still picture, or a mixture of them. The image information and the navigation information together are broadcast by a broadcasting station to the terminal apparatus. The navigation information indicates a plurality pieces of link-target image information. The cache unit stores a pair of image information and navigation information. The reproducing unit reproduces the image information. The monitoring unit monitors whether an operator has performed a certain operation responding to the image displayed. The receiving unit, before the operator performs the certain operation, receives a plurality pieces of image information which have possibility of being displayed and a plurality pieces of corresponding navigation information based on the navigation information, and stores the plurality pieces of image information and navigation information in the cache unit. The specifying unit specifies a piece of link-target image information based on the certain operation. The identifying unit identifies the piece of link-target image information as a piece of image information.
