VIDEO CODING METHOD AND APPARATUS FOR EFFICIENTLY PREDICTING UNSYNCHRONIZED FRAME |
摘要 |
<p>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.</p> |
