Method and apparatus for receiving metadata, EPG, or IPG signals in an integrated circuit for control purposes
Abstract:
An integrated circuit or system receives a bit pattern from a metadata, IPG, and or EPG signal. This bit pattern is then coupled to a circuit to provide a content control command to a recorder or to a processing circuit to generate a content control signal. In particular the bit pattern may be utilized in a manner to program, enable, or disable the generated control signal. Furthermore this content control signal provides resistance to a circumvention device. For example, the circumvention device is unable to remove sufficiently the content control signal, and content control is maintained.
