# 演習課題（３）－２の計算例

ビットレートの計算式

\begin{equation}
r = \frac{1}{\Delta_t}\times N_1 \times N_0 \times (\ell_Y + \frac{\ell_{C_b}}{4}+\frac{\ell_{C_r}}{4})
\end{equation}

SMTPE296M(1280$\times$720, 4:2:0, 30P)のパラメータ


*   $\Delta_t=1/30$ [1/s]
*   $N_1 = 720$
*   $N_2 = 1280$
*   $\ell_Y=\ell_{C_b}=\ell_{C_r}=8$ [bits]


```
delta_t = 1/30
N1 = 720
N0 = 1280
ell = 8

r = (1/delta_t)*N1*N0*(ell + ell/4 + ell/4)

print('ビットレート r = {:4.2f}'.format(r))
```

    ビットレート r = 331776000.00
