Abstract: PURPOSE: A video bit rate control method and an apparatus thereof are provided to increase accuracy and performance of bit rate and to increase the efficiency of image encoding. CONSTITUTION: A video bit rate controller determines target bit quantity of a current frame by using current frame type information(S430). The video bit rate controller calculates a QP(Quantization Parameter) about the current frame by applying the determined target bit quantity to a secondary rate distortion model(S450). The apparatus encodes the current frame by using the calculated QP(S490).

Abstract: PURPOSE: A bit rate controlling method for hierarchical coding structure capable of encoding a video of high efficiency is provided to apply a rate-distortion characteristic to a secondary rate-distortion model by using the property of rate-distortion according to a frame type of each time layer in consideration of a hierarchical coding structure. CONSTITUTION: QP(Quantization Parameter) of a first frame and QP of a second frame are determined by using actual generation bit quantity about each frame type of each temporal layer(301). Increase or reduction of CP id determined about QP of the first frame according to a target bit quantity of the second frame within the same time layer.

Abstract: PURPOSE: A method for encoding and decoding a video and a device using the same are provided minimize a signaling overhead by inserting bit depth information into blocks to be encoded and predicting the information from an upper level value or a surrounding value. CONSTITUTION: An encoding device determines a bit depth reference value per a sample for a PCM(Pulse Code Modulation) mode(S310). The encoding device determines a bit depth value per a sample of a block to which the PCM mode is applied(S320). The encoding device signals information about the bit depth value per a sample(S330). [Reference numerals] (S310) Determining a reference value of bit depth per sample for a PCM mode; (S320) Determining a bit depth value per PCM sample of a PCM mode target block; (S330) Signaling information about the determined bit depth value per sample
