摘要:
In a cache memory management device, a time measuring unit measures a time period required to obtain data from a database. The data obtained from the database is linked to the time information and both are stored in a data cache unit. If the data cache does not have sufficient room to store the data obtained from the database, a data replacement determination is made. In one embodiment, the data is replaced by referring to the total data access time. In a second embodiment, if a statistics processing unit judges that the access time and the size of each data are proportional to each other, then cache data is replaced by referring to the size information from a size calculation unit. If, however, the statistics processing unit judges that the access time and the size of each data are not proportional to each other, cache data is replaced by referring to the time information from the time measuring unit.

摘要:
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.

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 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.
