Abstract: The present invention discloses an encoding apparatus using a Discrete Cosine Transform (DCT) scanning, which includes a mode selection means for selecting an optimal mode for intra prediction; an intra prediction means for performing intra prediction onto video inputted based on the mode selected in the mode selection means; a DCT and quantization means for performing DCT and quantization onto residual coefficients of a block outputted from the intra prediction means; and an entropy encoding means for performing entropy encoding onto DCT coefficients acquired from the DCT and quantization by using a scanning mode decided based on pixel similarity of the residual coefficients.

Abstract: A smart chair control system linked with a reservation is proposed. the system is configured to include: a reservation server (120); a chair control system server (130) configured to interwork with the reservation server (120) and receive ticket reservation information from the reservation server (120); a main controller (140) configured to communicate with the chair control system server (130); a sub-controller (150) configured to communicate with the main controller (140); and a chair control board (155) configured to control a chair of a grandstand by communicating with the sub-controller.
