    • PROBLEM TO BE SOLVED: To make compatible both the use and protection of the digital contents, by protecting its contents from unauthorized use, even when the contents have been recorded on an open recording media such as a hard disk drive. SOLUTION: A secure manager 112 manages encipherment/decoding of the contents by using media ID with every recording media for recording the contents, when using the recording media 116 and 117 having the media ID. Meanwhile, when using an HDD 115 having no media ID, the secure manager 112 acquires system proper device ID via BIOS, and manages the encipherment/decoding of the contents recording on the HDD 115 by using its device ID. The device ID is stored in a secure area inside a computer system. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:即使当内容已经记录在诸如硬盘驱动器的打开的记录介质上时,通过保护其内容免受未经授权的使用,从而兼容数字内容的使用和保护。 解决方案:当使用具有媒体ID的记录介质116和117时,安全管理器112通过使用具有用于记录内容的每个记录介质的媒体ID来管理内容的加密/解码。 同时,当使用不具有媒体ID的HDD 115时,安全管理器112通过BIOS获取系统正确的设备ID,并且通过使用其设备ID来管理在HDD 115上记录的内容的加密/解码。 设备ID存储在计算机系统内的安全区域中。 版权所有(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a storage medium, capable of protecting contents by preliminarily registering revocation information in a specific storage area of the storage medium to thereby invalidate, when the storage medium is installed to unauthorized electronic equipment shown by the revocation information and used, the electronic equipment.
      SOLUTION: A revocation list RL from which PD (recording and reproducing device) to be invalidated for content protection can be discriminated is preliminarily registered in a read-only disclosure ROM area 132 ensured on PM (storage medium) 13. When the PM 13 is installed to LCM (content use management system) or PD and used, a controller 130 provided on the PM 13 receives information showing the equipment from the LCM or PD, refers to the revocation list RL based on the information, and determines whether the equipment is invalidated or not according to the reference result.

    • PROBLEM TO BE SOLVED: To efficiently carry out radio communication between each of mobile terminals and a base station by using a plurality of communication channels.
      SOLUTION: A wireless LAN access point 100 is provided with a plurality of wireless LAN modules 10, 20, 30 for simultaneously using several communication channels in a plurality of communication channels of mutually different frequencies. Mutually different communication channels 10, 20, 30 are set to the wireless LAN modules 10, 20, 30. The wireless LAN access point 100 detects the number of connected mobile terminals corresponding to the communication channels 10, 20, 30, and transmits communication channel information indicating the number of connected mobile terminals for each communication channel to the mobile terminals. Thus, a communication channel with a less number of connected terminals can be selected on the side of the terminal, thereby efficiently carrying out radio communications between each mobile terminal and the base station.

    • 要解决的问题:通过使用多个通信信道来有效地执行每个移动终端与基站之间的无线电通信。 解决方案:无线LAN接入点100设置有多个无线LAN模块10,20,30,用于在相互不同的频率的多个通信信道中同时使用多个通信信道。 相互不同的通信信道10,20,30被设置到无线LAN模块10,20,30。无线LAN接入点100检测与通信信道10,20,30对应的连接的移动终端的数量,并且发送通信信道 指示到移动终端的每个通信信道的连接的移动终端的数量的信息。 因此,可以在终端的侧面选择具有较少数量的连接终端的通信信道,从而有效地在每个移动终端与基站之间执行无线电通信。 版权所有(C)2005,JPO&NCIPI
