ABSTRACT:
A bitrate control method and apparatus for video sequence coding by using only intra pictures are provided. The rate control method includes: separating a video sequence formed only with intra pictures, into picture group units, slice units, and macroblock units; and performing bitrate control so that a predetermined amount of bits can be generated when encoding is performed. According to the method and apparatus, overflow and underflow of a buffer can be prevented.
