    • An integrated circuit (IC) includes a demodulator for receiving encrypted information data and a hardware unit that enables conditional access to the information data. The hardware unit includes a processing unit, a RAM, a ROM, multiple non-volatile registers, and an interface unit for transferring an attribute to the demodulator. The non-volatile registers may include an IC identification and an encryption key. The ROM includes a boot code that causes the processing unit to fetch a code from an external memory and store the fetched code in the RAM. The fetched code may include a certificate that ensures the authenticity of the code. The fetched code may be encrypted and decrypted by the ROM using the IC identification and the encryption key. The demodulator includes a descrambler for decrypting the received information data using the attribute. The information data may include digital radio or television content.
    • 集成电路(IC)包括用于接收加密信息数据的解调器和能够对信息数据进行条件访问的硬件单元。 硬件单元包括处理单元,RAM,ROM,多个非易失性寄存器和用于将属性传送到解调器的接口单元。 非易失性寄存器可以包括IC标识和加密密钥。 ROM包括引导代码,其使处理单元从外部存储器获取代码并将获取的代码存储在RAM中。 所获取的代码可以包括确保代码的真实性的证书。 所获取的代码可以使用IC标识和加密密钥由ROM加密和解密。 解调器包括用于使用该属性解密所接收的信息数据的解扰器。 信息数据可以包括数字无线电或电视内容。

    • Network interface devices and methods are provided. A particular network interface device includes a first network interface adapted to terminate one or more communication lines and a second network interface to terminate at least one coaxial line. The network interface device also includes at least one interface connector adapted to receive a removable plug-in module. The removable plug-in module includes a video unit that is operable to receive video data from a network device via at least one of the one or more communication lines and to process the video data for communication via the at least one coaxial line or a twisted wire pair when the plug-in module is connected to the at least one interface connector. The removable plug-in module also includes a power coupling device to receive power via at least one of the one or more communication lines.
