摘要:
A receiving unit 101 repeatedly receives a transport stream, and a specifying unit 102 specifies a purchase state. A restoring unit 103 generates a first audio-digital (AV) signal and interactive data, and an AV reproducing unit 105 generates a second AV signal. A combining unit 106 generates a data-AV combined signal by combining the generated second AV signal and a data signal generated from the interactive data. A data presentation restricting unit 115 outputs the interactive data and a purchase state signal. A control unit 107 receives an operation signal from an inputting unit 110 and outputs it to a data operation restricting unit 116. A data analyzing unit 104 analyzes a presentation element contained in the interactive data and generates video data, which is the data signal. A data judging unit 117 judges whether a currently-presented presentation element is included in the same group as a presentation element that is a link destination of the presented presentation element. When the purchase state is a viewing permitted state, the data operation restricting unit 116 outputs the operation signal. When the purchase state is a preview state or viewing prohibited state and when the above two presentation elements are included in the same group, the operation restricting unit 116 also outputs the operation signal.
摘要:
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.

摘要:
A data broadcast receiving apparatus includes a storage controlling unit and a reproduction controlling unit. The storage controlling unit selectively stores data modules among a plurality of data modules included in received broadcast data, into a module storing unit. The storage controlling unit also stores storage information for each of the plurality of data modules into a storage information storing unit, the storage information showing the presence or absence of the data module in the module storing unit, a reason of the absence of the data module, and the like. When the user selects a data module as a reproduction target, the reproduction controlling unit judges whether the data module is stored in the module storing unit, based on storage information of the data module in the storage information storing unit. If the data module is stored in the module storing unit, the reproduction controlling unit reads the data module and produces a display corresponding to the data module on a TV screen. If the data module is not stored in the module storing unit, the reproduction controlling unit displays a message informing the user of the fact and reason that the data module is not stored in the module storing unit.

摘要:
A data stream selection/output apparatus that selects and outputs a data stream composed of sequentially obtained data. The data stream selection/output apparatus obtains timing information indicating a time at which a first data stream being output should be switched to a second data stream. The data stream selection/output apparatus, in a time period including the time indicated by the timing information, scans the first and second data streams to detect a first boundary between data blocks of the first data stream and a second boundary between data blocks of the second data stream, where the data blocks conform to a transmission protocol higher than Transport Layer of OSI Reference Model. The data stream selection/output apparatus then stops outputting the first data stream at the first block boundary and starts outputting the second data stream at the second block boundary.
摘要:
A data transfer apparatus receives from an upper station a data stream that includes a plurality of types of repeat data, each type of repeat data being repeatedly transmitted by the upper station, and transfers the repeat data to a lower station, the data transfer apparatus including a storage unit having a storage area; an extraction unit for extracting the types of repeat data from the received data stream; a writing unit for writing the extracted repeat data to the storage area; a data structure ratio determination unit for determining a ratio between the types of repeat data to be output in a data stream per fixed length of time; and a data output unit for reading the repeat data stored in the storage unit, and outputting the read repeat data at the determined ratio.
