Abstract: The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound of the present disclosure, an organic electroluminescent device having improved driving voltage, luminous efficiency, and/or lifespan characteristics can be provided.

Abstract: A display apparatus and a display method are provided. The display apparatus includes a communicator configured to receive a pre-power on command signal from an external device, and a controller configured to activate a network communication function of the display apparatus based on the pre-power on command signal. The communicator is further configured to receive information of content from the external device, in response to the controller activating the network communication function, and the controller is further configured to reproduce the content based on the information of the content.

Abstract: Disclosed are a display apparatus, a mobile apparatus, a system including the same, and a connection control method thereof. The display apparatus includes: a camera configured to receive second communication interface information displayed and supported by a mobile apparatus; and a controller configured to set up a communication connection with the mobile apparatus, based on first communication interface information supported by the display apparatus and the second communication interface information displayed and supported by the mobile apparatus and received through the camera.

Abstract: A method of controlling an operation of booting an image reproducing apparatus is provided. The method includes: receiving an input signal for powering off the image reproducing apparatus; receiving from a main processor a memory address where an operation status of the image reproducing apparatus is stored, according to the received input signal; storing the received memory address; and converting a system of the image reproducing apparatus into a sleep by the sub-processor.

Abstract: A system and method for detecting a sampling clock offset of an analog-to-digital converter used to digitize an analog image signal. A method comprises buffering samples of an analog image signal, computing a value of an autocorrelation function using the buffered samples and a delayed version of the buffered samples, and repeating the computing a value for delays in a range of delays. The method also comprises computing a sampling frequency offset from the values of the autocorrelation function and changing a sampling frequency using the sampling frequency offset.

Abstract: A computer connected to a network, including a network part to process data received through the network; and a controller to detect environment identification data from the data received through the network, and to change an operating state of a system into a predetermined operating state corresponding to the detected environment identification data. Accordingly a computer, a control method thereof, and a network system is provided to automatically control an operation of the system, for convenience of a user, in accordance with the environment where a computer is in use by changing the operation of the system into the predetermined operation according to the detected environment identification data when the environment identification data received through the network is detected.
