Image display apparatus and method

摘要

An image display apparatus having a lower data transmission speed and less degradation of the image quality for displaying the image having a lower data-rate according to the state of a communications network and a method for enabling the same are provided. The apparatus, which transmits and receives data by way of the communications network, includes a screen size determiner which determines the screen size of image signals input according to control signals; an encoder which encodes the image signals according to the determined screen size; a controller which outputs control signals which determine the screen size by evaluating the state of the communications network and for transmitting the encoded image signals through the communications network; a decoder which decodes the image signals transmitted through the communications network; and a display which displays the decoded image signals.
