    • A computer watchdog system monitors and controls distribution content sent form producers, through distributors, to subscribers. The computer watchdog system acting to ensure the just execution of agreements between a producer of content and a distributor of content. The computer watchdog system serving as an agent trusted by both producers and distributors. The computer watchdog system may be equipped with tamper protection for resisting exogenous attempts to gain unauthorized access to the system. The computer watchdog system may be installed entirely within distributor's sites. Alternatively, the computer watchdog system may reside partially within distributor's sites and partially within subscriber's sites. The computer watchdog system logs and reports on information relating to the distribution of content. Further, the computer watchdog system may selectively transform content provided by a producer, customizing the content for distributors and subscribers.
    • 计算机看门狗系统通过分销商监视和控制从生产者发送的分发内容到用户。 计算机看门狗系统用于确保内容制作者和内容分发者之间的协议的正确执行。 作为由生产者和分销商信任的代理商的计算机看门狗系统。 计算机看门狗系统可以配备防篡改以抵抗外部尝试以获得对系统的未经授权的访问。 计算机看门狗系统可以完全安装在分销商的站点内。 或者,计算机看门狗系统可以部分地驻留在分销商的站点内,并且部分地驻留在订户的站点内。 计算机看门狗系统记录和报告与内容分发有关的信息。 此外,计算机看门狗系统可以选择性地转换由制作者提供的内容,为分发者和订户定制内容。
