摘要： A display apparatus capable of correcting an image quality change caused by long-term use is provided. The display apparatus includes: a display panel; a communicator configured to communicate with a service apparatus; and a controller configured to control the communicator to transmit operation information including a total operating time of the display apparatus and an operating temperature of the display apparatus, to the service apparatus; receive an image parameter from the service apparatus through the communicator, and based on the received image parameter data; process image data; and transmit the processed image to the display panel. The image parameter may include at least one of a brightness level, a contrast, a sharpness level, and a color density of the display panel.

摘要： A method for variably controlling a bit rate of video data through end-to-end channel status sensing in a Wireless Broadband (WiBro) network is provided. The method includes classifying wireless channel statuses of a transmission side and a reception side into normal and abnormal statuses during video data transmission; variably controlling and determining an encoding bit rate of a transmission side's encoder according to the classification result; and comparing the determined encoding bit rate with a Down Link Modulation & Coding Selection Level (DL MCS Level) which is a parameter of the reception side, so as to vary a final encoding bit rate of the transmission side.
