Abstract:
There is provided a network join method including transmitting a long beacon message including transmission timing information of a first short beacon message to a child node network device, transmitting a first short beacon message including information regarding an interval in which it is possible to transmit a message, to the child node network device according to a transmission timing of the first short beacon message, receiving a slot allocation request message from the child node network device according to the interval in which it is possible to transmit a message, and checking whether the child node network device joins a network, and transmitting a slot allocation confirmation message to the child node network device.
Abstract:
Disclosed are a multi-screen display system and a method of correcting a time synchronization of image signals respectively played by unit display panels. The multi-screen display system includes a multi-screen display apparatus configured to include a plurality of unit display panels and a timing sensing apparatus configured to sense, outside the multi-screen display apparatus, time synchronization information about the unit image frames respectively played by the unit display panels. The timing sensing apparatus calculates a time synchronization error between the unit image frames respectively played by the unit display panels, based on the time synchronization information, and transmits the time synchronization error to the multi-screen display apparatus.
Abstract:
A method and an apparatus for visualizing a scheduling result in a multicore system. A method for visualizing a scheduling result of a plurality of tasks with respect to a plurality of cores in a multicore system includes extracting scheduling data in a time section to be visualized, determining whether the number of the extracted scheduling data exceeds a preset first threshold value, if the number of the extracted scheduling data exceeds the preset first threshold value, performing reduction of the extracted scheduling data, and visualizing and outputting the reduced scheduling data.
Abstract:
Provided is a data transmitting and receiving method in which a display apparatus connectable to a wireless network transmits and receives data to and from a user terminal by using a pointing apparatus. The data transmitting and receiving method includes (a) acquiring position information of a region, pointed by the pointing apparatus, in the display apparatus and (b) transmitting data, corresponding to an object displayed in the region on a screen of the display apparatus, to the user terminal by using the pointing apparatus.
