Abstract: An improved method and system for the editing of unwanted content from transmitted program material. The system may be operated manually or automatically and its program recognition means may be positioned either locally at the controlled receiver or in a remote location. The system also has expanded editing capability to allow coordinated control of accessory devices and may be programmed without the necessity of an initial reception of unwanted content at the controlled receiver. It also simplifies and improves the reliability of previously disclosed methods for automatic program identification.

Abstract: A device which monitors information contained in broadcast electrical signals and which, when attached to or combined with the circuitry of a television, radio or other receiver, will automatically prevent reception of unwanted material.

Abstract: A device which monitors information contained in incoming telephone calls, and which, when attached to or combined with the circuitry of a telephone receiver, will automatically hold and display the identity of the caller while allowing the telephone bell to be rung only at certain times and/or for certain callers. The caller's identity can be determined by the called party without personally answering the telephone and without revealing to the caller whether the called party is at home or not. It can be used to automatically screen incoming calls and prevent the reception of calls which are unwanted. Accordingly, it can be used to allow wanted calls to ring the telephone's bell and thus, for example, awaken the user at night, while preventing all unwanted calls from disturbing the called party.
