    • A MIDlet Suite comprising one or more encrypted installation files is determined at a sending terminal device. A distribution description file comprising Super Distribution identification information for the MIDlet Suite is generated. A non-encrypted distribution archive file comprising the distribution description file and the MIDlet Suite is generated. The distribution archive file is transmitted to a receiving terminal device. The distribution description file is extracted and the extracted distribution description file is parsed in order to obtain the Super Distribution identification information. The MIDlet Suite is extracted from the distribution archive file, and installation information is displayed. Thus the receiving device is able to verify the contents of a received MIDlet Suite before the acquisition of an associated Rights Object, and the user can make a more informed decision whether to acquire the associated Rights Object or not.
    • 在发送终端设备处确定包括一个或多个加密安装文件的MIDlet套件。 生成包含MIDlet Suite的超级分发标识信息的分发描述文件。 生成包含分发描述文件和MIDlet套件的未加密分发归档文件。 分发归档文件被发送到接收终端设备。 提取分发描述文件,并解析提取的分发描述文件以获得超级分发标识信息。 从分发档案文件中提取MIDlet套件,并显示安装信息。 因此,接收设备能够在获取相关联的权利对象之前验证所接收的MIDlet套件的内容,并且用户可以做出更知情的决定是否获取相关联的权限对象。

    • A receiver (200) includes a mixing digital-to-analog converter (DAC) (208), a direct digital frequency synthesizer (DDFS), a transimpedance amplifier (TIA) (204) and a first polyphase filter (PPF) (202). The mixing DAC (208) includes a radio frequency (RF) transconductance section for providing an RF current signal responsive to an RF signal and a switching section. The switching section is coupled to the RF transconductance section and includes inputs for receiving bits associated with a digital local oscillator (LO) signal. The switching section is configured to mix the RF current signal with the digital LO signal to provide an analog output signal at outputs of the switching section. The transimpedance amplifier (TIA) (204) includes inputs each coupled to a respective one of the outputs of the switching section and outputs. The first PPF (202) includes inputs each coupled to a respective one the outputs of the TIA (204).
    • 接收器(200)包括混合数模转换器(DAC)(208),直接数字频率合成器(DDFS),跨阻抗放大器(TIA)(204)和第一多相滤波器(PPF) 。 混合DAC(208)包括射频(RF)跨导部分,用于响应于RF信号和切换部分提供RF电流信号。 开关部分耦合到RF跨导部分,并且包括用于接收与数字本地振荡器(LO)信号相关联的位的输入。 开关部分被配置为将RF电流信号与数字LO信号混合,以在开关部分的输出处提供模拟输出信号。 跨阻放大器(TIA)(204)包括各自耦合到开关部分的相应输出端和输出端的输入端。 第一PPF(202)包括各自与TIA(204)的输出相连接的输入。
