Abstract: A car navigation map update system includes map update data delivery equipment and one or more car navigation terminals. The map update data delivery equipment includes a map update data broadcasting section for broadcasting map update data by radio waves. Each car navigation terminal receives the broadcast map update data, stores the map update data in a map update data storing medium, and utilizes the map update data in connection with map information data prestored in a map data recording medium. This enables the terminals to collect latest map data using a receiver already installed in the car navigation terminals without adding a data transmitter, thereby solving a problem of a conventional car navigation system which requires a data transmitter installed in the car navigation terminal for sending a message to a host to obtain the map update data, and hence complicates the configuration and increases the cost of the system.

Abstract: A receiving board is set into a personal computer, a digital broadcast signal is received in the receiving board, and a high-definition television (HDTV) picture of the digital broadcast signal is decoded in the receiving board. The HDTV picture or an output picture of the personal computer is selected in a selector switch of the personal computer, and the selected HDTV picture or the selected output picture of the personal computer is directly displayed in a CRT of the personal computer or an HDTV monitor of a high-definition television set without passing through a peripheral component interconnect (PCI) bus of the personal computer. Therefore, because the HDTV picture does not pass through the PCI bus, a user can view the HDTV picture of the digital broadcast signal in the CRT of the personal computer in real time.
