Abstract: A method of controlling a display apparatus is provided. The method of controlling a display apparatus includes acquiring channel information regarding a broadcast content that a user watched through a broadcast receiving apparatus that is connected to the display apparatus, in response to a voice keyword being input from the user, transmitting information regarding the input voice keyword and the channel information to an external server, from the external server, receiving content information related to the voice keyword among content information that is determined based on the channel information and provided by a broadcast content providing service that the user subscribes to and displaying the content information related to the received voice keyword.

Abstract: An image processing method is provided, including obtaining an input image, generating a distance field image including distance values by calculating each of the distance values respectively corresponding to pixels of the obtained input image, and enlarging the input image using the generated distance field image, wherein the generating of the distance field image includes, with respect to each pixel of the input image, determining each pixel as a center pixel and determining pixels at a constant distance away from the center pixel as reference pixels, calculating a shortest distance from among distances between the center pixel and reference pixels indicating an edge among the reference pixels, and determining the calculated shortest distance as a distance value corresponding to each pixel.

Abstract: A system and method of generating a test clock signal for scan testing of a main circuit in a semiconductor device includes receiving an external clock signal and a control signal and generating a gated clock signal by gating an internal clock signal based on the control signal. The internal clock signal has a frequency higher than a frequency of the external clock signal. One of the external clock signal and the gated clock signal is selectively output based on the control signal.

Abstract: Graphics display systems include a graphics data compression circuit having a data encoder therein. The data encoder is configured to compress second color graphics data to be rendered as a second pixel of a display into a data string containing a data field and a header field. The header field contains at least one repetition flag that identifies a degree to which components of the second color graphics data match corresponding components of first color graphics data to be rendered as a first pixel of the display.
