A baffle includes a plate-shaped support structure, which is made of an at least partially air-permeable and at least partially sound-absorbing material and which has a first surface, a second surface facing away from the first surface, a thickness, and a cut-out portion. The baffle further includes a frame structure, to which the support structure is fastened, an at least partially sound-transparent layer, which is applied to the entire first surface of the support structure and which forms, in particular, a projection surface for projecting an image thereon or which is an imaging layer for displaying an image, and an acoustic transducer, which is arranged in the cut-out portion behind the layer, generates sound and is able to emit the sound through the layer.

An advertising apparatus comprises an unmanned aerial vehicle (UAV) having at least one motor, and at least one propeller operably connected to said at least one motor for providing vertical lift to said UAV, and a three-dimensional advertising assembly operably attached to said UAV, said advertising assembly comprising a display medium for providing a non-planar, viewable display for conveying at least one image to a viewer.

An accessory suitable for an electronic device is provided. The electronic device has a display area. The accessory includes a coupling portion and a cover portion. The coupling portion is suitable to be coupled to the electronic device. The cover portion is connected to the coupling portion and is suitable for covering the display area of the electronic device. The cover portion has a plurality of light-transmitting areas, and the light-transmitting areas are arranged on the display area in an array. An image generated by the display area is projected out of the cover portion through the light-transmitting areas. Moreover, an electronic assembly containing the electronic device and the accessory is also provided. Furthermore, a control method is also provided for controlling the electronic assembly. A method is also provided for forming an accessory.

The present invention relates to a curved ceiling structure, the ceiling structure characterized by having a curved shell shape over the seats of a theater while exposing the screen. Therefore, according to the present invention, structural continuity with the screen curved in horizontal and vertical axes can be ensured, and by ensuring design integrity with the screen curved in horizontal and vertical axes, a sense of immersion can be imparted to an audience and an enhanced life-like sensation can be delivered thereto.

The present invention relates to a theater having provided with a screen having curvature, and a chair control system for same and, more specifically, to a theater comprising: a screen having predetermined curvature in the long axial direction or the short axial direction; and theater chairs provided so as to face the center of the screen, wherein the screen is tilted. Therefore, by providing the angles of theater chairs to vary with respect to the location in a theater having provided with a screen that has curvature in the horizontal axis as well as the vertical axis, the present invention enables securing of an optimal field of vision for audience.

The present invention relates to a method of providing image data based on cloud streaming. In particular, the method uses memory space of a terminal, prestores image data in the terminal, captures an execution screen regarding execution of a specific application, extracts video content from the prestored image data based on the captured execution screen and information regarding the execution screen, simultaneously encodes individual items of the extracted video content, and provides the encoded video content to a screen. Thus, according to the present invention, usage of the cloud streaming server and the network may be reduced by an amount commensurate with the resources utilization of the terminal. Network load may also be reduced when a live video or a VOD video is not being watched, and the rich GUI experience may be guaranteed in a standby state.

The present invention relates to a variable screen system for providing audience with more enhanced immersion by having a content image projected on a screen that is in the shape of a curved surface. More particularly, the present invention relates to a variable screen system comprising: a support for fixing a frame on which a screen is formed; and a theater server for controlling the support and thereby changing the curvatures of the frame or the screen formed on the frame.

The present invention relates to a screen-holding structure, and more specifically to a screen-holding structure to withstand the weight of the screen by means of a screen holding apparatus for the entire region or a part of the screen to prevent the phenomenon in which a screen held by a frame sags downward due to the weight of the screen. According to the present invention, the curved surface of the screen can be smoothly maintained by minimizing the downward sagging phenomena of the curved screen, thereby allowing content image to be projected onto the screen without distortion, and consequently allowing a viewing environment having a high sense of immersion and enhanced stereoscopic effect to be provided to an audience.

The present invention relates to a curved screen support comprising a plurality of vertical bars arranged vertically from the ground, and a plurality of horizontal bars attached to the vertical bars at one end in the horizontal direction with respect to the ground, wherein horizontal bars are characterized in that the line connecting the other ends of the horizontal bars arranged on the same vertical axis has a curved shape of a set curvature, and the line connecting the other ends of the horizontal bars arranged on the same horizontal axis has a curved shape of set curvature. Therefore, according to the present invention, a curved screen having a curvature along the horizontal axis as well as the vertical axis can be stably held, and by controlling the curvature and angle of the curved screen, enhanced life-like effects can be provided to an audience.

The present invention relates to a screen, and more specifically to a screen, to which a content images are projected, comprising screen regions each having a mutually different reflectance. According to the present invention, with respect to implementing a screen having a non-flat surface, as the content images can be projected onto all screen regions while maintaining uniform brightness, an audience can be provided with a content viewing environment by means of screens having a variety of shapes, while satisfactorily maintaining the quality of the of the projected a content images.
