A video signal processing method according to the present invention is characterized by constructing a palette map for a current block that is encoded in a palette mode, obtaining an escape present flag based on a number of palette entries included in a palette map, deriving a palette index in a unit of a sample of a current block according to a predetermined scan order, and reconstructing a current block by using at least one of an escape present flag, a palette map or a palette index.

A method for processing a vide signal, according to the present invention, configures a palette map for a current block encoded in a palette mode, induces a palette index according to a predetermined scanning order by a unit of a sample of the current block, and restores each sample of the current block by using a palette entry having a map index having the same value as that of the palette index induced from the palette map.

A method to communicate the effects of physical touches made to a touch screen includes acquiring touch information from a touch screen of a first device which is touched and controlling a touch screen of a second device to simulate effects of the touch applied to first device. The method utilizes piezoelectric elements, pressure sensors, temperature sensors, and temperature adjusting devices installed in the touch screens of both devices. A tactile interaction device is also provided.

A video signal processing method according to the present invention is characterised by constructing a palette map for a current block that is encoded in a palette mode; inducing a palette index for each sample of the current block in a pre-determined scan order; and restoring the respective samples of the current bock based on the palette map and the palette index.

The touch sensor includes a touch detection area with at least a part of a curved area having a curved edge. In the touch detection area, a plurality of first electrodes and second electrodes disposed side by side in a first direction and in a second direction are disposed. A plurality of first electrodes disposed side by side in the first direction are connected to each other. A plurality of second electrodes disposed side by side in the second direction are connected to each other. In the curved area, distances between the plurality of first electrodes and the second electrodes in the first direction gradually change in the second direction.

A method is provided. The method includes receiving a request for a frame buffer from an application; identifying a next frame generation duration based on history information of frame timings; identifying a next frame generation start time based on a sync time corresponding to a next vertical sync (VSYNC) signal and the next frame generation duration; and providing the frame buffer to the application at the next frame generation start time.

A display device and a method therefor are provided. The display device is provided. The display device may include a display, an input module comprising input circuitry configured to detect or receive an input (e.g., a user input) from at least one input device, and a processor configured to zoom in on a specified first menu icon at a first zoom-in magnification from an original size if the input is for specifying the first menu icon in a menu icon list displayed on the display. The first zoom-in magnification may differ from a zoom-in magnification of a second menu icon from among other menu icons of the menu icon list.
