<P>PROBLEM TO BE SOLVED: To effectively display desired moving image information and still image information on a display device by using a digital transmission line to efficiently transmit digital data such as train information and moving image information. <P>SOLUTION: Train information transmitted by using a digital transmission line 1 is transmitted from a train information device 10 to a transmission device 80 by using a digital transmission line 2. Transmission data including moving image information and a display command are transmitted from an image storing and distributing device 70 to the transmission device 80 by using a digital transmission line 75. Transmission data including train information, moving image information, and the display command are transmitted from the transmission device 80 to a display device 11 by using an intra-vehicle transmission line 6. Transmission data including moving image information and the display command are transmitted between transmission devices by using an inter-vehicle transmission line 5. Transmission data are transmitted between the display device 11 and other display devices 11 and 21 in the same vehicle through an inter-display transmission line 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
