Abstract: In a train interior monitoring method, in order to improve the efficiency in memory-usage, when an event occurs, data containing image information, which has been recorded in a temporary image memory, is recorded in an image memory without any processing in order to reduce the file size of the data. Further, data containing image information is recorded in the image memory represents for only a period of time before and after detection of the occurrence of the event, the period of time being set according to what the event is. After a given period of time has elapsed, the data containing the image information is processed in order to reduce its file size and then recorded in the image memory.

Abstract: There are provided a news/weather-forecast editing device that updates content with a high real-time sensitivity and information that constitutes an external program listing; a news/weather-forecast dedicated distribution server that creates an external program listing showing a display order of the content with a high real-time sensitivity, an advertisement-content editing device that updates content with a low real-time sensitivity and an advertisement program listing, which shows a display order of the content with a low real-time sensitivity and also a display order that follows the external program listing; a content database that stores therein the content and the program listings; a distribution server that periodically checks the content database and distributes updated content and program listings; and individual distribution devices that distribute content and program listings that have been distributed from the distribution server to vehicles that display the content according to the display order.

Abstract: The present invention provides an in-vehicle congestion-status display system that notifies railway users of a congestion status of each vehicle of a train. The in-vehicle congestion-status display system includes a main server that calculates a congestion rate immediately before boarding, which is a predicted value of a congestion rate when alighting of users is complete, of each vehicle of a train, based on a congestion rate during travel and an alighting rate acquired in a past and held as information indicating a difference between a congestion rate during travel immediately before arriving at the station and a congestion rate when alighting of users is complete after arriving at a next stop of the train, and a display device that notifies users of the congestion rate immediately before boarding calculated for each vehicle of the train.

Abstract: An in-train information distribution and display system and enables dynamic selection and display of contents having higher advertising effectiveness according to train information. A first program listing having time slots set therein and a plurality of advertising content data associated with each of the time slots of the first program listing, as candidates for program material, are prepared in a ground content-distribution server. An on-board central-distribution server determines the program material by selecting one of the plural advertising content data associated with each of the time slots of the first program listing, based on train information and passenger information obtained from a train-information central unit. A program listing having determined program materials constitutes a second program listing.

Abstract: It is intended to provide an e-mail communication terminal apparatus which, when connected to an e-mail system that is limited in the amount of data that can be communicated at one time, makes it possible to transmit and receive data having an amount larger than the limit amount. A division control section divides transmission data into divisional data based on a predetermined data amount when the transmission data has an amount larger than a limit amount of data that an e-mail system to which to establish connection can communicate at one time. A transmitting section transmits the divisional data. A receiving section receives data. A recombination control section recombines the data received by the receiving section when the received data are divisional data.
