系统内冗余或重复数据的度量,表明存储和潜在性能问题效率低下。
1 BR = 2 SC
1 SC = 0.5 BR
例子:
将15 块冗余转换为源编码冗余:
15 BR = 30 SC
| 块冗余 | 源编码冗余 |
|---|---|
| 0.01 BR | 0.02 SC |
| 0.1 BR | 0.2 SC |
| 1 BR | 2 SC |
| 2 BR | 4 SC |
| 3 BR | 6 SC |
| 5 BR | 10 SC |
| 10 BR | 20 SC |
| 20 BR | 40 SC |
| 30 BR | 60 SC |
| 40 BR | 80 SC |
| 50 BR | 100 SC |
| 60 BR | 120 SC |
| 70 BR | 140 SC |
| 80 BR | 160 SC |
| 90 BR | 180 SC |
| 100 BR | 200 SC |
| 250 BR | 500 SC |
| 500 BR | 1,000 SC |
| 750 BR | 1,500 SC |
| 1000 BR | 2,000 SC |
| 10000 BR | 20,000 SC |
| 100000 BR | 200,000 SC |
