Benefits of technology

If all of distributed software received at a receiving terminal apparatus-can be automatically updated simply in the reception order of software, the process at the receiving terminal apparatus is easy. However, in this case, data or programs which are required not to be altered may be installed during update. Problems such as an inability of using the terminal apparatus may occur.
It is an object of the present invention to provide a distribution system capable of correctly and easily updating software.
It is another object of the present invention to provide a terminal apparatus capable of easily executing a necessary update process in accordance with distributed software.
According to another aspect of the present invention, distributed data or a program is checked whether it is required to be updated, and distributed data or program used for update are selected from distributed data and programs. After the update sequence of distributed data and programs is determined, they are updated. In this manner, a terminal apparatus easy to use can be provided.

Problems solved by technology

Problems such as an inability of using the terminal apparatus may occur.
If a user is required to check distributed data or programs and determine the data or programs used for update and the update sequence, highly sophisticated technical knowledge is necessary and a work load is required.

first embodiment

this invention will be described with reference to FIGS. 1 to 11. FIG. 1 is a diagram showing the structure of a system according to the first embodiment. The system of this embodiment is constituted of a terminal apparatus 150 and a station 100 which distributes data or programs to the terminal apparatus 150. Although the terminal apparatus for receiving data or programs may be mounted on a fixed facility, in this embodiment it is assumed that the terminal apparatus is mounted on a mobile unit. As an example of such a mobile unit, vehicles distributed in a broad area are used by way of example. The terminal apparatus may not be movable, and not only the vehicles but also other various mobile units may be used such as those used for overland transport and marine transport, and air planes.

Although a variety of apparatuses may be used as the terminal apparatus of the mobile unit, a typical example, a terminal apparatus with a car navigation function, is used in the following descript...

second embodiment

FIGS. 13 to 15 are flow charts illustrating the operation of the invention. FIG. 13 is a flow chart illustrating the operation to be executed by the software management center 1250. FIG. 14 is a flow chart illustrating the operation to be executed by the terminal apparatus 1250 during the “update software acquisition mode”. FIG. 15 is a flow chart illustrating the operation to be executed by the terminal apparatus 1250 during the “software update mode”.

When a user wishes to update software, the user makes the input unit 175 display the display window 1600 for the “update software acquisition mode”. In order to display the display window 1600, the user makes the input unit 175 display a mode setting dialog 1630 to be used for setting a mode, and in this state, an update software acquisition mode item 1640 is selected. In this manner, the display window 1600 is displayed.

The display window 1600 has an update request button 1610 for transmitting a software update request to the soft...

Abstract

A terminal apparatus has a reception unit for receiving a data group or a program group distributed from a satellite or a ground distribution system, and an update sequence management unit. The update sequence management unit searches data or a program of the terminal apparatus to be updated and data or a program necessary for updating the data or the program of the terminal apparatus, from the data group or the program group, determines an update sequence of the searched program or data, and updates the program or data of the terminal apparatus in accordance with the determined update sequence.

Description

BACKGROUND OF THE INVENTION The present invention relates to a distribution system for distributing data or programs and a receiving terminal apparatus for receiving distributed data or programs, respectively via a satellite or a ground station. Conventionally, distribution of data or programs (hereinafter described as software) is generally conducted by using storage media. Generally, a user installs distributed software by using storage media. If software can be automatically updated (including installation of new software), it is very convenient. In addition, without particular knowledge, new software can be updated and many people can use latest software. Techniques regarding renewal of software is disclosed, for example, in JP-A-11-98477. SUMMARY OF THE INVENTION If all of distributed software received at a receiving terminal apparatus-can be automatically updated simply in the reception order of software, the process at the receiving terminal apparatus is easy. However, in...
