Abstract:

A method () and apparatus () for processing a video signal inserts a unique digital signature into the video signal. Thus, rampant duplication or distribution can be traced back to a particular set-top box or receiver. According to one aspect of the present invention, the unique digital signal is inserted into the vertical blanking interval. An apparatus () for processing a video signal includes a processor () receiving the video signal and outputting a modified video signal having a vertical blanking interval, which includes a digital signature uniquely identifying the processor (). A memory () stores the digital signature and a teletext generator () coupled to the memory () and the processor () and generates a teletext signal that includes the digital signature for insertion into the vertical blanking interval by the processor () prior to the processor () outputting the video signal.

Abstract:

A method is provided that determines whether to allow an application (app) for use or restrict the app on a set top box (STB). The method includes the steps of measuring at the STB, one or more resources used by the app; comparing at the STB, one or more thresholds set by an operator; and determining if the one or more resources used by the app exceed one or more thresholds set by the operator. Another method is provided that monitors applications (apps) that are installed a set top box (STB) for illegal or harmful activity by a policy manager. This method includes downloading and copying an app from an external source; installing or uninstalling the app into an application folder; providing a notification informing the policy manager of the installing or uninstalling of the app; and evaluating the app be installed or uninstalled.
