摘要： A vehicle navigation apparatus determines whether or not the currently traveled route having a current vehicle position matches with estimated routes after determining, on the basis of the traveled route history, the estimated routes which correspond to destination candidates. Then, the navigation apparatus further determines whether or not the subsequent portion of the estimated route overlaps with other estimated route, for selecting one of the destination candidates. The vehicle navigation apparatus thus selects the destination candidate, in a highly accurate manner in terms of user preference, based on the traveled route history.

摘要： There is disclosed a technique for automatically creating a detailed program table for playing contents according to various conditions. According to this technique, a constraint condition generation unit 103 acquires a condition (constraint condition) related to a user and describes this constraint condition through the use of a constraint condition description function. A constraint condition solution unit 104 carries out constraint solution processing by making reference to content attribute information stored in a content attribute storage unit 124 on the basis of the constraint condition description function supplied from the constraint condition generation unit, thereby deriving an optimal program table (optimal solution) defining a temporal arrangement of a plurality of contents. Moreover, in the case of constraint excess which leads to finding no optimal solution, a constraint condition priority acquisition unit 105 narrows down an optimal program table or performs recalculation while, in the case of constraint shortage which leads to finding a plurality of optimal solutions, a score setting unit 106 narrows down an optimal program table or performs recalculation. On the basis of the optimal program table thus created, a content acquisition unit 109 carries out content acquisition processing and a program playing unit 110 performs playing processing.

摘要： A technology that makes a program line-up related to contents distributed to a user side, depending on various conditions, preferences, and communication environments of the user side that views and listens to the content is disclosed. According to the technology, an on-board device (content receiving and reproducing device) 1 receives, from a service server 5, potential content list information of contents that can be distributed from a content server 7. The on-board device 1 sorts appropriate content from among the contents in the potential content list information and decide on a reproducing order of the contents, based on conditions of the user side, such as user preferences and vehicle conditions, conditions related to an environment on the user side, such as the communication environment, and conditions related to the contents, such as the genre of the content. The on-board device 1 creates program table information (timetable) and transmits the program table information to the content server. As a result, reception and reproduction of the contents from the content server can be performed in adherence to the program table information.

摘要： When a vehicle deviates from a guide route at a first branch point, the state of the first branch point is memorized. Afterward, when a second branch point becomes a target for a route guide and the state of the second branch point is similar to the memorized state, a user of the vehicle is provided with a guide for preventing deviation from the guide route at the second branch point with a manner of the guide changed. This procedure allows learning of tendency of the user with respect to a state apt to cause the user to mistake a guide route. A guide to help prevent a user from deviating from a guide route at a branch point can be thus performed appropriately.
