Various embodiments of the present invention may comprise: a display unit for displaying a screen corresponding to a virtual reality mode; and a control unit for sensing an interrupt due to occurrence of at least one event, changing event-related information related to the occurred event to a form corresponding to the virtual reality mode, and controlling the changed event-related information to be displayed on the screen operated corresponding to the virtual reality mode. In addition, other embodiments are possible for the various embodiments of the present invention.

A fast search method for searching for an optimum codeword for nearest neighbor vector quantization. An upper boundary value and a lower boundary value between which an optimum codeword will exist in a codebook are calculated using a distortion of a designated element in an input vector and an experimentally determined threshold. Further, a start point and an end point for codebook search are determined using a binary search method from a codebook rearranged in descending order, and a full search scheme is applied only within a search range calculated by the determined start point and end point, thereby determining an optimum codeword for nearest neighbor vector quantization.
