摘要:
A passenger information control device having a video display controller that transmits video data sent from a ground transmission controller to display devices in a train includes: a storage unit that stores a program table and the video data, the program table storing a number of times an advertisement video has been presented, a validity period of the advertisement video, a time period from the last presentation time to the present, and a volume of the video data, being associated with each advertisement; a deletion determining unit that determines whether to designate the video data as a candidate for deletion based on a program table; and a deleting unit that deletes the video data stored in the storage unit based on determination by the deletion determining unit.

摘要:
A delivery control central device installed in a lead car of a train delivers video information including moving image information and still image information to a delivery control terminal device of each subsequent car via an inter-car transmission path. The video information is delivered based on video content and a content display schedule that are both wirelessly received from a ground station through a transceiver device. The delivery control terminal device of each car is sequentially connected to the delivery control terminal device of an adjacent car, sequentially delivers the delivered video information to the adjacent car, and delivers the delivered video information to a video output device via an in-car transmission path inside its own car. A video output device generates video signals from the delivered video information, outputs the video signals to a display device, and displays the video signals by the display device.

[Problem] To obtain an on-train video information delivery control and display system that is capable of efficiently delivering moving images and still images by digital transmission and providing moving images and still images to passengers inside a train passenger compartment while avoiding cost increase and without having to divide the transmission path of the moving images and still images.[Means for Resolution] A delivery control central device 10 installed in a lead car configuring a train delivers video information comprising moving image information and still image information to a delivery control terminal device 30 of each car via an inter-car transmission path 1 on the basis of contents and a contents display schedule wirelessly received from the ground by a transceiver device 9, the delivery control terminal device 30 of each car is sequentially connected to the delivery control terminal device 30 of an adjacent car, sequentially delivers the delivered video information to the adjacent car, and delivers the delivered video information to a video output device 50 via an in-car transmission path 2 inside its own car, and the video output device 50 generates video signals from the delivered video information, outputs the video signals to a display device 70, and displays the video signals by the display device 70.
摘要:
Provided is a network that is constituted in a train formation; communication relay devices; terminal devices; and a position-information distribution device. The communication relay devices rewrite position information from the position-information distribution device to vehicle information indicating positions of vehicles that are provided with the communication relay devices and transfer rewritten information. The terminal devices include an IP-address correspondence table in which IP addresses that are set so as not to overlap with each other for respective types of the terminal devices and are to be used while corresponding to the vehicle information and connection destination information of the terminal devices correspond to each other. IP addresses to be allocated to the terminal devices are decided on the basis of the correspondence table and the vehicle information from the communication relay devices.
摘要:
A communication apparatus for performing communication among cars of a train includes two or more connection ports, and two or more VLANs set through VLAN numbers in each connection port. When receiving a specific kind of packet for disabling the VLAN settings, the communication apparatus regards the set two or more VLANs as the same network with respect to the specific kind of packet and transfers the packet to a desired destination apparatus set in any one of the VLANs irrespective of the VLAN settings.
摘要:
A path-information obtaining unit obtains a piece of path information of a communication network by inquiring a port number of an Ethernet switch that transmits a MAC address of a request source of an IP address. An IP-address specifying unit specifies an IP address that corresponds to the piece of path information of the communication network by referring to an IP-address correspondence table, and distributes the specified IP address to the request source of an IP address.

A memory control device includes a CPU, a flash ROM that records therein first information having undergone an error-correction coding process and second information not having undergone an error-correction coding process, an address line switch that switches between a first path that connects an address bus to the ROM so that the CPU can read the first information and a second path that connects the address bus to the ROM so that the second information can be erased, written, and read, a decoder that performs error correction on the first information and performs decoding, and a second switch that switches between a third path that connects the decoder to the data bus so that information decoded by the decoder is transmitted to the data bus and a fourth path that connects the ROM to the data bus so that the second information can be erased, written, and read.
