Abstract: One aspect of the present invention discloses a license authentication method in a wireless access point (AP). The method comprises receiving a license authentication request including license information from a client; calculating a distance of the client from the wireless access point in response to the received license authentication request; based on the calculated distance, determining whether the client exists within a range of allowed positions for license authentication related to license location information for allowing authentication of a license included in the license information; and determining whether to authenticate in response to the license authentication request based on the determination result.

Abstract: One aspect of the present disclosure provides a device for extracting and transmitting data from a shop floor image, the device comprising: an encoder configured for receiving, from a facility operating system, streaming video data of a display screen of a monitor of the facility operating system on a shop floor, and for encoding the streaming video data in real time; a video data analyzer configured for receiving the real-time encoded streaming video data and for extracting data by figuring out and tagging a data presentation location in the real-time encoded streaming video data using a video data analysis algorithm; and a communication unit configured for transmitting to a data engine the real-time encoded streaming video data, and the data extracted by the video data analyzer.

Abstract: Provided are a transmitter and receiver for remote control support, an operation method thereof and a remote control system. The transmitter connected to a source device includes a first reception unit for receiving display screen data of the source device, an encoder for encoding the display screen data received at the first reception unit, and a first transmission unit for transmitting the encoded data to a receiver using a real-time communication protocol, Here, the transmitter is a hardware device wired to the source device through a digital interface.

Abstract: Provided is a first recording apparatus for recording a video stream in association with a second recording device. The first recording apparatus includes a video stream receiving unit for receiving a video stream from a video providing device via a network, a buffering unit recording a portion of the received video stream in a queue, a transmission unit relaying the video stream to the second recording device, a storage unit recording the video stream, and a switching unit for switching an operation mode to one of a relay mode for relaying the video stream to the second recording device based on a state report periodically received from the second recording device and a recording mode for storing the video stream in the storage unit.

Abstract: The present invention discloses a method for visualizing 4D data by integrating received data, at a server system. The method may include a step of extracting data for extracting layer information representing a relation between items, status information representing state or event of each of the items, and connection information enabling each of the items to be related to internal/external system from received at least one raw data, a step of generating contents for generating an object from the extracted information as and integrally implementing the generated object in a visualization space, and a step of visualization control for visualizing and controlling the generated contents, wherein each of the object and the visualization space may be integrally implemented to 4D data with location information and time information.
