    • Systems and methods for distributing content over various mediums in a service provider network are disclosed. Such mediums may include an optical fiber and a cable line having a bandwidth less than that associated with the optical fiber. In certain embodiments herein, content may be distributed over the cable line, or relatively low bandwidth medium, according to characteristics of the optical fiber, or relatively high bandwidth medium. In one embodiment, data packets may be scheduled using first in first out (FIFO) scheduling for distribution over the cable line using Orthogonal Frequency Division Multiplexing (OFDM). Using this approach, increased bandwidths may be achieved over cable lines. Additionally, certain embodiments herein are directed to maintaining a forward/reverse channel split, which may exist in a PON, over a cable line. Further, certain embodiments herein may relate to dynamic allocation of subcarriers in an OFDM signal in response to changes in quality of service.
    • 公开了在服务提供商网络中通过各种介质分发内容的系统和方法。 这种介质可以包括具有小于与光纤相关联的带宽的光纤和电缆线。 在本文的某些实施例中,内容可以根据光纤的特性或相对高带宽的介质分布在电缆线路或相对低带宽的介质上。 在一个实施例中,数据分组可以使用先进先出(FIFO)调度进行调度,以使用正交频分复用(OFDM)通过电缆线分布。 使用这种方法,可以通过电缆线路实现增加的带宽。 此外,这里的某些实施例涉及通过电缆线路维持可能存在于PON中的前向/反向信道分离。 此外,这里的某些实施例可以涉及响应于服务质量的变化的OFDM信号中的子载波的动态分配。

    • Systems and methods providing content having digital rights management (DRM) applications separable from other authorization applications are provided. A system may include a distribution service provider system in communication with a content provider system and consumer premise equipment (CPE) for the transmission of content from the content provider system to the CPE device. The distribution service provider system may: receive A/V content provided by the content provider system, wherein the A/V content includes a DRM application; apply a conditional access system (CAS) application to the A/V content that is independent of the DRM application; and transmit the A/V content including the CAS and the DRM applications to the CPE for presentation. The CPE device can perform DRM authorizations with the content provider or a third-party DRM provider.
    • 提供了提供具有与其他授权应用可分离的数字版权管理(DRM)应用的内容的系统和方法。 系统可以包括与内容提供商系统通信的分发服务提供商系统和用于从内容提供商系统向CPE设备传输内容的消费者内部设备(CPE)。 分发服务提供商系统可以:接收由内容提供商系统提供的A / V内容,其中A / V内容包括DRM应用; 将条件访问系统(CAS)应用程序应用于独立于DRM应用的A / V内容; 并将包括CAS和DRM应用的A / V内容发送到CPE以进行呈现。 CPE设备可以与内容提供商或第三方DRM提供商执行DRM授权。
