Abstract (en)
[origin: WO9012630A1] A cinema-concert hall comprises a general screen (1), lateral screens (2, 3), an upper screen (4) and a floor (5) of the stage. The upper screen (4) is mounted rotatably around an axis (18) so as to serve as a roof of the general screen (1), in its horizontal position and creating, in its vertical position, an additional surface of the general screen (1). Each lateral screen (2, 3) is rotatable around a vertical axis (14) and forms, in one position, side-scenes, and in another one serves as a prolongation of the general screen (1).
