    摘要： An access platform or other network elements can include multiple line cards configured to encrypt data. The platform and/or each of the line cards may receive encryption management data that conforms to a predefined encryption management data interface. The encryption management data received by a particular line card may be generated by a conditional access system device and converted to conform to the encryption management data interface by an encryption manager. Line cards may alternatively be configured for connection to separate encryption hardware components. Line cards may include a block of field programmable gate arrays or other type of programmable hardware that can be configured to execute an encryption module.

    摘要翻译： 访问平台或其他网络元件可以包括被配置为加密数据的多个线路卡。 平台和/或每个线路卡可以接收符合预定义的加密管理数据接口的加密管理数据。 由特定线路卡接收到的加密管理数据可以由条件访问系统设备生成，并被加密管理器转换为符合加密管理数据接口。 线路卡可以替代地被配置用于连接到单独的加密硬件组件。 线路卡可以包括一组现场可编程门阵列或可配置为执行加密模块的其他类型的可编程硬件。

    摘要： A gateway device configured to receive IP video content may select and use transmission methods that maintain a certain quality of service for delivering the content. A transmission method may be selected based on a network to which the client device is connected. The gateway device may select a network through which the content is to be delivered depending on a variety of factors including bandwidth availability, client compatibility, quality of service provided and the like. A gateway device may further be configured to convert multicast transmissions to unicast, to provide dynamic storage of content for pre-positioning and other purposes and/or to provide other functions.

    摘要： Digital information can be carried on the fiber leg of an access network using binary modulation. Binary modulated data received at an O/E node can then be modulated onto an analog waveform using quadrature amplitude modulation or some other technique for modulating an analog waveform and transmitted over, for example, the coaxial leg of the network. The O/E node may also receive an analog signal, over the coaxial leg, modulated to carry upstream data from subscriber devices. The O/E node may demodulate the upstream signal to recover the upstream data and forward that upstream data over the fiber leg using a binary modulated optical signal.
