Abstract: When traveling to a destination reported in a television broadcast or the like, the user has had to make a memo while watching the television and, when actually traveling by car, the user has had to enter necessary information into an in-vehicle terminal by looking at the memo. A broadcast provider broadcasts a travel program together with travel destination information related to it, and a television terminal presents the received broadcast and travel destination information to the user. If the user desires to travel to the destination thus presented, the television terminal downloads the received travel destination information into a memory card. When the user goes out by car at a later date, the in-vehicle information terminal acquires the travel destination information from the memory card, a route setting section sets the route by using travel destination location information contained in the travel destination information, and a communication section acquires real-time information by using a method of connection to a real-time information having the travel destination information.

Abstract: A speech interpreting device. Speech is input in a first language. The input speech is recognized. One or more word strings of the first language are extracted and displayed. The word strings correspond to a result of the speech recognition. A word string is selected from the displayed word strings. The selected word string is expected to become an object of conversation to a second language. When a whole or a part of the selected word string is specified, candidates of a term which corresponds to contents of the specified whole or part of the selected word string are extracted and displayed. One of the displayed candidates is selected. The selected word string is converted to a second language.
