    • A software conditional access system (CAS) for media services provided to a Media Distribution Device, such as a set top box (STB), is disclosed. The STB may be connected to a Media Delivery Service Provider via a broadband connection. Over the broadband connection, a CAS application may be downloaded to the STB, maintained and dynamically updated. Because the CAS is implemented by software on the STB, it is inexpensive to install, maintain and update. When a user desires to purchase media services through the STB, a request, with identifying information, is sent to the Media Delivery Service Provider via the broadband connection. The service provider cross-references the identifying information with a user's account to determine whether to allow the user to view the media service requested. If the service provider determines to allow the user to view the media service, the user's account (typically maintained by the service provider) is charged and a key is downloaded via the broadband connection to the STB. The key allows the user to view the requested media service to be presented for user viewing, hearing or other use. After the requested media service ends, after a predetermined amount of time, etc., the CAS application may delete the key.
    • 公开了一种提供给诸如机顶盒(STB)等媒体分发设备的媒体服务的软件条件访问系统(CAS)。 STB可以经由宽带连接连接到媒体传送服务提供商。 通过宽带连接,可以将CAS应用程序下载到STB,维护和动态更新。 由于CAS由STB上的软件实现,因此安装,维护和更新成本低廉。 当用户希望通过STB购买媒体服务时,带有识别信息的请求将通过宽带连接发送到媒体传送服务提供商。 服务提供商用用户帐户交叉引用识别信息,以确定是否允许用户查看请求的媒体服务。 如果服务提供商确定允许用户查看媒体服务,则用户的帐户(通常由服务提供商维护)被收费,并且通过宽带连接将密钥下载到STB。 密钥允许用户查看要呈现给用户观看,听觉或其他用途的所请求的媒体服务。 在所请求的媒体服务结束之后,在预定的时间等之后,CAS应用可以删除密钥。

    • Methods and systems provide clickstream captures at a remote component, such as a video control system of a television network, by receiving user commands generated by the viewer that are sent to the remote component concurrently relative to when they are generated by the viewer. The commands are captured and then information related to these commands is stored remotely from the premises of the viewer. Additionally, the user commands may be executed remotely such as at a video control system of a television network or alternatively may be executed at the premises of the viewer such as within a set top box. Information related to these user commands continues to be stored remotely from the premises of the viewer after the user commands have been executed such that the information related to these user commands can be processed as necessary and used for various purposes.
    • 方法和系统通过接收由查看者生成的用户命令,在远程组件(例如电视网络的视频控制系统)上同时发送到远程组件,同时发送到远程组件。 这些命令被捕获,然后与这些命令相关的信息远离观察者的处所。 此外,用户命令可以远程地执行,例如在电视网络的视频控制系统处,或者可以在诸如机顶盒之类的观众的场所执行。 在执行用户命令之后,与这些用户命令相关的信息继续从观众的场所远程存储,使得可以根据需要处理与这些用户命令相关的信息并用于各种目的。
