摘要： An adjustable television mask used to cover the "black bars" present on a television screen during broadcast of a signal transmitted in "letterbox" or "wide-screen" format. The invention includes four members that connect together to form a frame-like structure with an aperture therein. The desired portion of the transmission may be viewed while the "black bars" are blocked from view. The mask may be adjusted so the desired picture appearing on the screen fits exactly within the aperture formed by the mask. As a result, the viewing enjoyment of transmissions in "letterbox" or "wide-screen" formats can be significantly improved.
