METHOD FOR SCALABLE VIDEO CODING WITH VARIABLE GOP SIZE, AND SCALABLE VIDEO CODING ENCODER FOR THE SAME

摘要

A video coding method supporting a variable group of pictures (GOP) size, a video encoder, and the structure of an encoded bitstream are provided. The coding method includes receiving a video sequence, and encoding the received video sequence into a bitstream with a variable GOP size. The video encoder includes a determiner determining a GOP size variably according to a predetermined criterion, and a scalable video coding unit encoding an input video sequence into a bitstream with the determined GOP size.
