摘要： A method of efficiently predicting a frame having no corresponding lower layer frame in video frames having a multi-layered structure, and a video coding apparatus using the prediction method is provided. In the video encoding method, motion estimation is performed by using a first frame of two frames of a lower layer temporally closest to an unsynchronized frame of a current layer as a reference frame. A residual frame between the reference frame and a second frame of the lower layer frames is obtained. A virtual base layer frame at the same temporal location as that of the unsynchronized frame is generated using a motion vector obtained as a result of the motion estimation, the reference frame, and the residual frame. The generated virtual base layer frame is subtracted from the unsynchronized frame to generate a difference, and the difference is encoded.

摘要： A scalable video codec includes an encoder that encodes an original moving picture; a rate control unit that allocates an optimal amount of bits for each coding unit based on a bit-rate desired by a user; a pre-decoder that receives a bit-stream and extracts a bit-stream having an appropriate amount of bits; and a decoder that decodes image sequences of the moving picture from the extracted bit-stream, so as to reconstruct the original moving picture. In particular, the present invention focuses on the operation performed in the rate control unit 340. The rate control unit operates a definition step of a bit-rate function available for use in the predecoder, a pre-summation step to thereby obtain the uniform visual quality, an approximation to determine the distortion function, and a normalization step to allow the total allocated bit-rates to be equal to a target bit-rate.
