Abstract: A FrontHaul Multiplexer (FHM) for relaying communications between a signal processing device and a plurality of radio devices includes a storage unit that stores a table in which device identification information of each of the plurality of radio devices is associated with beam identification information assigned to the radio device; a scheduling information reception unit that receives, from the signal processing device, scheduling information of a user terminal performing radio communications with the plurality of radio devices; a determination unit that acquires from the table the device identification information associated with the beam identification information of uplink included in the scheduling information and then determines from the acquired device identification information the radio device in charge of the user terminal; and a transmission unit that transmits to the signal processing device an uplink signal transmitted from the determined radio device.

Abstract: When digital contents sold to a user become useless to the user, the digital contents and the license of the digital contents are collected or purchased from the user so that a privilege such as discount sale of other digital contents or addition of discount points is granted to the user having the license.

Abstract: The invention provides a personalized playback continuation system for digital content that allows continuation of content playback even when the user is at a different location or a different playback terminal. For each user, a server manages a personal playback action history, e.g., which content was played back up to which point. If playback is interrupted, playback continuation information for the content at that point in time is sent from the playback terminal device to the server and stored in the personal playback action history. When an interrupted content playback is resumed, the server uses the personal playback action history and the content information describing the properties of the content to generate playback start information, which is sent to the playback terminal.

Abstract: A coupon management system transmits or broadcasts a coupon information from a broadcasting/transmitting system to a receiving system together with a program or commercial message. The receiving system generates a coupon issuance request on the basis of the coupon information, and attaches to the request an identifier of the program or commercial message with which the coupon information is provided. The coupon issuance request attached with the identifier is transmitted from the receiving system to a service center. The service center issues a coupon on the basis of the coupon issuance request and calculates a number of issued coupons for each program or commercial message.

Abstract: Digital contents are distributed from a center side distribution apparatus to a terminal apparatus via a shop side distribution apparatus, an audiovisual fee for digital contents with limited time is collected from a user, all digital contents capable of being accessed only at a limited place are allowed to be viewed and listened during a limited time period, the number of audiovisual times of digital contents viewed and listened at the terminal apparatus is managed, the numbers of audiovisual times of digital contents are totaled, and a copyright fee is calculated in accordance with the totalized number of audiovisual times. It is therefore possible to reliably collect a copyright fee even in the shop such as a manga tea shop and a compound cafe at which the copyright fee was not able to be collected to date. It is also possible to strictly manage viewing and listening digital contents.
