Abstract: When a program transmission apparatus divides a program into a plurality of partial programs before transmission, a program reception execution apparatus executes a partial program when the partial program has already been received, and, when the execution needs to proceed to from a present partial program to a next partial program, executes the other partial program when the next partial program has been received.

Abstract: A data transmission apparatus has a multiplexing unit that cyclically multiplexes presentation information and navigation information stored in a transmission data storage unit according to control by a multiplexing control unit and a transmission unit that transmits the multiplexed stream. The reception control unit of a data reception apparatus sets filter conditions in a filter condition storage unit of a TS decoder unit in accordance with user operation indications. The presentation information and navigation information separated by the TS decoder unit are outputted via a reproduction unit to a display unit and an audio output unit.

Abstract: 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.

Abstract: A data transmission apparatus has a multiplexing unit that cyclically multiplexes presentation information and navigation information stored in a transmission data storage unit according to control by a multiplexing control unit and a transmission unit that transmits the multiplexed stream. The reception control unit of a data reception apparatus sets filter conditions in a filter condition storage unit of a TS decoder unit in accordance with user operation indications. The presentation information and navigation information separated by the TS decoder unit are outputted via a reproduction unit to a display unit and an audio output unit.

Abstract: 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.

Abstract: 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.

Abstract: 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.
