    • A content reception and reproduction apparatus and content reception and reproduction method capable of avoiding the discontinuity of content reproduction and preventing the user from experiencing an unpleasant feeling, such as irritation or anxiety, so that the user can pleasantly enjoy the content, has an auxiliary content acquiring mechanism to acquire a reproducible content other than a main content, as an auxiliary content. A content switching mechanism switches a content for reproduction by a reproduction mechanism to any one of the main content and the auxiliary content. The main content for reproduction is switched to the auxiliary content when the amount of accumulation of the main contents falls short of a predetermined reference amount during a reproduction of the main contents. The content for reproduction is returned to the main content when the amount of accumulation exceeds the reference amount.

    • In a wireless communication system, slave units such as operation switches and the like are configured such that the higher the priority level of an information signal to be transmitted from each slave unit is, the shorter a period t1 of a carrier sense to be performed before the transmission is set. Therefore, when the slave units attempt to transmit information signals of different priority levels by using the same time slot, one of the slave units whose information signal to be transmitted is of the highest priority level is given the shortest carrier sense period t1 before the transmission of the information signal, and therefore, can transmit the information signal at the earliest timing. Accordingly, by causing the slave unit which becomes able to transmit the information signal at the earliest timing to transmit the information signal, the information signal of the highest priority level can be transmitted at the earliest timing, while the other units are caused to sense, by carrier sense, the transmission, and put off transmission of their own information signals.
    • 在无线通信系统中,诸如操作开关等的从单元被配置为使得要从每个从单元发送的信息信号的优先级越高,在之前执行的载波感测的周期t1越短 传输被设置。 因此,当从单元尝试通过使用相同的时隙来发送不同优先级的信息信号时,要发送的信息信号为最高优先级的其中一个从单元被给予传输之前的最短载波检测周期t1 的信息信号,因此能够在最早的时刻发送信息信号。 因此,通过使能够在最早定时发送信息信号的从单元发送信息信号,可以在最早的定时发送最高优先级的信息信号,同时使其他单元感知, 通过载波感知,传输,并推迟传输自己的信息信号。

    • A radio base station, when detecting a collision of reception signals, transmits an access-restricted transmission allow signal IDLE2 to a irrelevant-to-collision radio terminal PS3 for access restriction. A plurality of relevant-to-collision radio terminals PS1 and PS2, when receiving the access-restricted transmission allow signal, set transmission delay times TR1 and TR2 determined by random numbers, respectively, and when receiving the access-restricted transmission allow signal after the lapse of their respective delay times, start the same transmission operation as when receiving a normal transmission allow signal. A separate radio terminal PS3, when receiving the access-restricted transmission allow signal before intended new signal transmission, suspends the new signal transmission until receiving the normal transmission allow signal.
    • 无线基站在检测到接收信号的冲突时,向接入限制的无关的无线终端PS3发送接入限制的发送允许信号IDLE2。 多个相关碰撞无线电终端PS1和PS2在接收到受限制的发送允许信号时,分别设置由随机数确定的发送延迟时间TR1和TR2,并且当接收到接入受限制的发送允许信号 经过其各自的延迟时间,开始与接收正常发送允许信号时相同的发送操作。 单独的无线电终端PS3在接收到受限制的传输之前允许在预期的新信号传输之前的信号,暂停新的信号传输,直到接收到正常的传输允许信号。

    • A radio terminal 1 has a self-terminal information storing section 4 for storing terminal information of its own, an other terminal information storing section 3 for temporarily storing terminal information which is sent from other radio terminals, and a master determining section 2 for determining a radio terminal appropriate for being a tentative master, based on the stored terminal information. This master determining section 2 determines the tentative master based on the specified information of the terminal information such as transmission power, battery information and network address information. Since, if a user selects an appropriate radio terminal and starts the construction of a temporary network, the radio terminal acquires terminal information of all other terminals and determined an optimum tentative master, the network is then constructed while being the determined tentative master as a center, and communication can be conducted.
