Abstract: PURPOSE: A bit rate control method and a device thereof are provided to perform real time bit rate control for encoding an ultra definition video by considering a hierarchical encoding structure. CONSTITUTION: A bit rate control unit allocates a bit amount for an intra section (S430). The bit rate control unit allocates a bit amount for a Group Of Picture (GOP) (S440). The bit rate control unit allocates a bit amount by frame (S450). The bit rate control unit applies a bit amount allocation weighted value to each hierarchy level by using a relative ratio of each result bit amount after performing initial frame encoding to each frame type/hierarchy level by using an initial quantization parameter. [Reference numerals] (AA) Start; (BB,DD,FF) No; (CC,EE,GG) Yes; (HH) End; (S410) Determine an initial quantization parameter; (S420) Encode an I frame; (S430) Allocate a bit amount for an intra section; (S440) Allocate a bit amount for a GOP; (S450) Control a bit rate by frame; (S460) Has the current GOP ended ?; (S470) Has the current intra section ended ?; (S480) Has an image encoding process ended ?

Abstract: PURPOSE: A method for controlling down link power is provided to control downlink power corresponding to the state of each channel excluding the cooperation between base stations. CONSTITUTION: A method for controlling down link power comprise steps of: selecting the most inferior mobile station as a power control target(S602); creating the minimum channel information of the selected mobile station(S603); establishing a target SIR(Signal-to-Interference/noise Ratio) based on the minimum channel information; calculating the transmission power using the target SIR(S605); and controlling the downlink power based on the transmission power.
