Abstract :
By studying the MPEG-2 based output rate control strategy in detail, the mechanism of accurate bit-rate control and rational bit allocation is analyzed. To solve the difficulties of bit-rate control from the drastic changes of coded bits, a bit-rate control strategy under scene change is proposed
