摘要:
Because wired connections make changing the seating configuration difficult, a wireless client device enables stable wireless transmission. The wireless client device wirelessly transmits to and receives data signals from an access point inside an aircraft. The wireless client device has a seat unit with a seat portion on which aircraft passengers sit, an antenna for sending and receiving the data signals, a signal processing arrangement operable to handle data signal receiving and transmitting processes, and a signal output arrangement operable to output processed reception signals. The antenna arrangement, signal processing arrangement, and signal output arrangement are disposed to the seat unit.

In a case where a thumbnail image is displayed at the time of insertion of an image file storage medium including an automatic reproduction file, the thumbnail image is displayed only for the image file which contains description of automatic reproduction in an automatic reproduction file. Also, a thumbnail image of an image file which contains description of non-automatic reproduction in the automatic reproduction file is replaced with a dummy image or displayed as a thumbnail image not apparently capable of being recognized in response to a user request.

Changing the seating configuration when there are wired connections to each seat is difficult. A wireless transmission system and method communicate wirelessly while also preventing interference with the ground communication system. The wireless transmission system wirelessly transmits data signals inside the aircraft, and has an altitude zone identification arrangement f or determining in which of N altitude zones the aircraft is flying, access points that can transmit the data signals wirelessly on any one frequency band selected from among M frequency bands, client units for receiving the data signals, and a selection unit for selecting one of the M frequency bands based on the altitude zone in which the aircraft is flying. The altitude zone identification arrangement includes an aircraft altitude detection unit and system control unit, and the selection unit includes the system control unit.

摘要:
A radio communication system includes radio terminal apparatuses each arranged at a previously determined position, radio base station apparatuses for holding radio communications with these apparatuses, and a communication system controller for communicating with the respective radio terminal apparatus via the respective radio base station apparatuses connected thereto via a LAN. The communication system controller stores therein an ad-hoc radio communication permission table indicating permission or non-permission of each of direct radio communications between the respective radio terminal apparatuses, judges whether or not the direct radio communication is permitted based on the ad-hoc radio communication permission table, in response to a request signal for a direct radio communication with a further radio terminal apparatuses received from each radio terminal apparatuses via the radio base station apparatuses, and transmits a notice signal including a result of the judgment to the radio terminal apparatus which transmitted the request signal.
