摘要： PROBLEM TO BE SOLVED: To provide a technology for viewing/listening the main content suitably and presenting the subcontent information desired by individual in a content receiving system utilizing the network of digital broadcast wave and broadband. SOLUTION: Subcontent control receivers A(101) and B(102) transmit a request for acquiring ID information and subcontent inherent to each subcontent control receiver from a communication control section (405) to a main content receiver/display 100. The main content receiver/display 100 separates a subcontent corresponding to this acquisition request at a content separation control section (310). A request information input/transmission control section (313) transmits the separated subcontent and received ID information to a subcontent controller/receiver. The subcontent controller/receiver determines subcontent acquisition by that ID information. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a digital content distribution system for efficiently changing the order of reproduction of a plurality of digital contents. SOLUTION: The license server 13 of the digital content distribution system has an updatable utilization order information database 138 for registering utilization order information for indicating the order of reproduction of a plurality of digital content data distributed to a terminal unit 3 via a network 2. When second digital content data are specified in a license acquisition request from the terminal unit 3, a license issuing section 133 determines whether first digital content data whose reproduction order is determined to be ahead of that of second digital content data, according to utilization order information in a utilization order information database 138 have been already reproduced by the terminal unit 3. Only when it is determined that the first digital content data have been already reproduced, the license issuing section 133 takes out license information required for reproducing the second digital content data in the terminal unit 3 from the license information management database 137 for transmitting to the terminal unit 3.

摘要： A support method for helping the user find a desired program from a collection of recorded television programs easily and quickly, and a recording/reproducing apparatus using this method. The recorded program viewing support system, when recording a television program, records electronic program information on the program, classifies the electronic program information according to predefined program category criteria, and successively assigns predefined category numbers (recording channels) to the program to be recorded. Before the user views a recorded program, the user specifies the number of the recorded channel. A recorded channel number is allocated with a category item and hence the user can easily know the contents of the recorded program. The user can change the channel number successively or directly specify it by using a remote controller to find a desired program easily and quickly. When disk media such as HDD and DVD-RAM are used as a storage in particular, the recorded programs can be randomly accessed allowing the user to zap through recorded programs.
