A navigator monitors the current play position of the multimedia content and compares that position with navigation objects. Each navigation object defines a start position, a stop position, and an filtering action to perform on the portion of the multimedia content that begins at the start position and ends at the stop position. When the current play position falls within the portion of multimedia content defined by a particular navigation object, the navigator activates the filtering action that was assigned to the navigation object. Filtering actions include skipping, muting, reframing, etc., the portion of multimedia content defined by a navigation object. A variety of systems may be used to implement the present invention, such as computer systems (consumer and server), television systems, and audio systems. ## Claims ### Claim 1 A method of suppressing multimedia content comprising: using at least one processor, accessing information associated with at least one object from a remote server through a communication link, the at least one object associated with a multimedia content stream from a content source and comprising a configuration identifier identifying a configuration of a system with which the at least one object will be applied for content suppression, an indicator identifying a start of a portion of the multimedia content stream, and another indicator identifying an end of a portion of the multimedia content stream;
