Description
ti+1−ti=1/Mが成り立つ。
B0=F
Bi+1=min(B,Bi―bi+R(ti+1−ti)) ・・・(1)
Bi≦B
Bi−bi≧0 ・・・(2)
このような条件が満たされている間は、エンコーダは、バッファオーバーフローやアンダーフローを発生させてしまうような符号化を行うようなことがないとされている。
B0=B
Bi+1=min(B,Bi―bi+Rmax(ti+1−ti)) ・・・(3)
Bi―bi≧0 ・・・(4)
この条件が満たされるとき、エンコーダは、デコーダ側でバッファアンダーフローが起こらないような符号化を行うことになる。デコーダバッファが一杯になった時は、エンコーダバッファは空であり、符号化ビットストリームが発生していないことを意味する。従って、エンコーダは、デコーダのバッファオーバーフローを起こさないように監視する必要は無い。
B2(i)=B(i)―b(i)
B(i+1)=B2(i)+R/(Frame Rate) ・・・(5)
ただし、if(B(i+1)>B)B(i+1)=Bとし、B(i)の最大値はBである。また遅延量FはF=Bとする。
Bmin=B―min(B2(i)) ・・・(6)
このときのRをRminとすれば、上記のような方法により(Rmin、Bmin)を決定することができる。
B2(i)=B(i)−b(i)
B(i+1)=B2(i)+R/(Frame Rate) ・・・(7)
となる。ただし、以下の条件に基づくアンダーフローに対する監視が行われる。
if(B2(i)<0){
Fmin=Fmin+(0―B2(i));
B2(i)=0;}
if(B(i+1)>B)B(i+1)=Bランダムアクセスポイント間の全てのフレームに対して上記した検査が行われることにより、(Rmin、Bmin、Fmin)が決定される。
