摘要： A plurality of HTML files having their file names which may directly be recognized by a filtering part 415 in a data receiver are stored in a data storage part 411. File names of the HTML files are assigned to their headers by a data converter 412, and the files converted and multiplexed are repeatedly transmitted by a data multiplexing and transmitting part 413. A filtering part 415 selects the data having exact match with the filtering condition. A data processing part 419 performs data processing required for generating images, and the images thus generated are displayed on a screen of the display part 421. The data processing part 419 provides a switching command to a filtering conditions varying part 417 when an operator enters a file to be linked through an input part 420. The file to be linked is received as a result of changing the filtering conditions. In this way, the files required can be received and be displayed dynamically without storing all the HTML files linked one another even in temporary basis.

摘要： A data reception apparatus that includes a storage unit 263 for storing a direct directory message body specifying a data block identifier by the reference name, a key information selection unit 258 for obtaining the reference name, a reception unit 152 for receiving multiplexed data of indirect directory message blocks, data blocks, and the direct directory message body data, a separation unit 254 for separating the multiplexed data, a directly obtaining unit 264 for outputting the data block identifier using the direct directory message body, a selection unit 155 for outputting the identifier using indirect directory message bodies, a directory message body obtaining unit 156, an indirect obtaining unit 257, a data block selection unit 253 for selecting the data block according to the output identifier and for extracting a data file, a selection unit 261 for restoring and storing the direct directory message body, and a restoration unit 262. When a direct directory message body includes a reference name, a data block identifier may be directly specified by the reference name without tracing indirect directory message bodies, and when a direct directory message body does not include a reference name, another direct directory message body is obtained and stored. As a result, the time for reception process is reduced.

摘要： An object is to perform retrial processing according to the allowable volume on communication lines made available at response information receiving equipment. A broadcast unit 140, when broadcasting video and audio, includes retrial information in that broadcast, according to the allowable volume on the communication lines between the television receivers and the response information receiving equipment 150. Television receivers effect display based on the received digital data. Response information input by users is sent to the response information receiving equipment 150. The television receivers make retrial transmissions based on the received retrial information when communications could not be established with the response information receiving equipment 150. This retrial information is responsive to the allowable volume on the communication lines between the television receivers and the response information receiving equipment 150, wherefore retrial transmissions are made according to the allowable volume on the communication lines.

摘要： The present invention provided a content delivery system that can deliver content by way of the Internet. In the system, a browser requests a content server to deliver a startup file. The content server transmits the startup file to the browser. The startup file describes that the content is to be delivered by streaming or that it is to be delivered by downloaded files. A content reproducing section determines if the content is that to be delivered by streaming or that to be delivered by downloaded files according to the description of the startup file it receives from the browser. A television receiving set may be used as content processing apparatus for receiving the delivery of the content from a content delivery apparatus of such a system.

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： 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.
