Abstract: Provided is a content caching broadcast transmission system that receives content from a content server, converts the content, and transmits the content through a non-real-time broadcast protocol. A receiver receives broadcast content through the non-real-time broadcast protocol, converts the broadcast content into web content, stores the web content, and forwards the web content to a client terminal in a unicast manner. The web content may be an Internet application package including a plurality of web documents and a series of scripts necessary for playback. A web object included in the Internet application package may be parsed, and addresses of links included in the web object may be converted such that the addresses are accessible in a receiver and then may be transmitted.

Abstract: A head-end system for terrestrial broadcast based on a virtualized broadcast framework includes a media configured to store a broadcast head-end virtualized component (BHVC) corresponding to all pieces of software related to a head-end device for transmission of ATSC 3.0 terrestrial broadcast, a plurality of worker nodes configured to transfer data to an exciter of a transmitting station by installing the BHVC stored in the media and performing a function of a typical head-end, and a mater node configured to monitor the plurality of worker nodes while storing and managing a container for installing the BHVC stored in the media in the worker nodes, and thus, modularizes a series of functions related to broadcast transmission in software units and effectively provides a broadcast service in a public or private cloud environment with departing from a broadcast device based on hardware or dedicated software.

Abstract: Provided is a method and device for a waste water treatment process. In one exemplary embodiment influent waste water and a defined portion of treated effluent water are combined during a first time interval to produce pretreated water. The pretreated water is dosed with selective chemical additives formulated to cause separation of solid and liquid media during a second time interval, producing separated water. Remaining solid media is removed from the separated water with a sludge filter to produce treated effluent water.

Abstract: Provided is a wireless power transmission device to reduce an electromagnetic wave except for a signal to be transmitted during wireless power transmission, the wireless power transmission device including a transmitter configured to generate a magnetic field by inputting a high-frequency power signal generated by a transmission circuit into a first coil, a receiver configured to generate an induced current by allowing the generated magnetic field to pass through a second coil, and a reducer configured to reduce a harmonic component of the high-frequency power signal using a third coil inserted on a path between the transmitter and the receiver.

Abstract: Provided is a dielectric layer that has a rock salt structure in a room temperature stable phase. The dielectric layer is made of a compound having a chemical formula of BexM1-xO, where M includes one of alkaline earth metals and x has a value greater than 0 and less than 0.5.

Abstract: An electronic device is provided. The electronic device includes a circuit board having a sound input hole penetrating through both surfaces of the circuit board, a microphone mounted on the circuit board, the microphone configured to receive a sound through the sound input hole, a first grounding pad surrounding the sound input hole on a surface of the circuit board, and a second grounding pad surrounding the first grounding pad on the surface of the circuit board. The microphone is mounted on the circuit board by soldering the microphone to the first and second grounding pads.

Abstract: An electronic device having a microphone device is provided. The electronic device includes at least one case frame which forms the external appearance of the electronic device, at least one microphone device which is disposed in the at least one case frame, and at least one microphone hole which is formed in a position corresponding to the at least one microphone device of the at least one case frame, and is disposed in a region which is not visually exposed in the at least one case frame.

Abstract: A multi-vision system and a method of controlling a display device usable in a multi-vision environment are disclosed. The multi-vision system includes a video source providing a video signal, a user input unit receiving multi-vision arrangement information from a user, a display device coupled to the video source for receiving the video signal. The display device, which is further coupled to the user input unit for receiving the arrangement information, initially determines an image portion of the video signal on the basis of the received arrangement information, adjusts a size of the determined image portion, and displays the size-adjusted image portion. The arrangement information indicates a user-preferred multi-vision arrangement and a position of the display device in the multi-vision arrangement.
