A motion picture presentation device with at least one motion picture display device, a multitude of seats for viewers and a movement device are configured with at least five linear drives. With the linear drives, the seats can be collectively moved in at least five degrees of freedom. At least one linear drive is fixed to a swivelling arm. At least two linear drives are immovably fixed at a respective base point, and a base element to which the seats are fixed such that they can be swivelled. The arrangement can be brought out of a first docking position, in which the base element can be docked at an access point, into a presentation position, in which the base element is swivelled by a swivel angle of at least 15° in relation to its first position, by activating the movement device. The base element can be brought from the docking position into the presentation position by swivelling the arm upwards.

An awning bar includes an awning bar body, the awning bar body having a length extending between a first end and a second end. The awning bar further includes at least one power track extending along the awning bar body. The power track includes at least one magnet configured to provide magnetic attachment to the power track and provide power to an accessory upon contact with the power track. An awning bar kit includes an awning bar and at least one awning bar accessory. An awning bar system includes an awning bar and at least one arm attachable to the awning bar. The arm is configured to move the awning bar away and towards a vertical wall.

A projector includes a communication unit configured to communicate with an external device, an operation unit configured to receive a user operation, and a system control unit. The system control unit is configured to validate a network function of the communication unit in response to receipt of a particular key sequence received by the operation unit in a stand-by state. The system control unit is configured not to validate the network function of the communication unit even if the operation unit receives the particular key sequence in an image projection state.
