Method for scalable video coding with variable GOP size, and scalable video coding encoder for the same

摘要

The present invention relates to a video relates to a compression, more particularly, to video coding method having a variable GOP size, and a video encoder and the encoded bit-stream structure. ; Scalable video coding method includes generating a bitstream by encoding gamyeo change to the step of receiving a video sequence, and the received video sequence, GOP size. ; The scalable video encoder includes a determination unit, and inputs the determined unit to code a GOP size for a video sequence bit stream received scalable video encoding which generates a variable for determining a GOP size in accordance with a predetermined criteria. ; Video compression, scalable, GOP merging, a video coding
