摘要： There are provided a content distribution system and a license management method for performing, in a collective manner, license management of a plurality of resources contained in contents. Each piece of content contains one upper-level resource (which is first referred to within the content), at least one lower-level resource (which can be referred directly or indirectly from the upper-level resource), one startup document and a license-corresponding document (which is an information file for performing, in a collective manner, license management of the resources contained in the content). The startup document contains at least upper-level resource reference destination information and at least one piece of license information for identifying view licenses required for viewing the resources contained in the content. In each resource, if link information for accessing other content is described, information for accessing the startup document of the other content is described.

摘要： A template storage unit stores a plurality of templates. A material data receiving unit receives material data. A combining rule storage unit stores a plurality of combining rules that each indicate a combining condition as a combination of attribute information, such as a type of material data and a version number, and a name of a template to be combined with when the combining condition is met. A combining instruction unit judges whether a combining condition of any of the combining rules is met or not and instructs a combining unit to combine the material data with the template when the combining condition is met. The combining unit combines the material data or a combination of the material data with the specified template according to the combining rule.

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 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.

摘要： A packet filtering apparatus selectively outputs packets among a plurality of inputted packets. A plurality of conditions are stored, with each condition being specified by a partial data position that indicates a position of a data part of a packet, comparison data to which the data part is to be compared, and a comparison criterion for comparing the data part and comparison data. Different conditions contain different comparison criteria. When filtering packets, a condition in one of the stored conditions is selected, and a data part of an inputted packet is compared with the comparison data of the selected condition according to the comparison criterion in the selected condition. Packets are selectively outputted depending on the result of the comparison.

摘要： In a content delivery system including a server and content processing apparatus connected to each other across a network, a content delivered by the system is encrypted with a content key Kc, and supplied along with a sublicense encrypted with a work key Kw to a DTV. The sublicense includes a second use condition under which a content is used and a content key Kc for decrypting an encrypted content. The work key Kw for decrypting an encrypted content is included in a main license. The main license is supplied to the DTV separately from the content. The main license includes, in addition to the work key Kw, a first use condition under which a content under a subscription contract is used.

摘要： A receiving unit (101) of a print data generating apparatus (100), which enables a printing that reflects user's preferences even in a digital broadcasting environment, receives and modulates digital broadcast waves. A video/data separating unit (102) separates a signal received from the receiving unit (101) into a video packet, an audio packet and a data packet that includes print information. A print information storing unit (104) is a RAM for storing print information, or the like, and reads the print information from the data packet received from the video/data separating unit (102), and stores it. A print information converting unit (108) reads the print information stored in the print information storing unit (104) and image data stored in an image storing unit (106), updates the print information by inserting, into the print information, image information representing the image data, based on the read-out print information and image data, and transmits the updated print information to a print information notifying unit (109). The print information notifying unit (109) transmits the received print information to a printing apparatus (120).
