Table 2
Three-layer (CIF-SD) spatial SVC coding versus single layer (4CIF/SD) coding (“SOCCER” video sequence, 30 fps, 300 frames, GOP size is 16).
| Quantization parameters | Single layer (4CIF/SD) | CIF-SD | Bit-rate overhead (%) | PSNR [dB] | Bit-rate [kb/s] | PSNR [dB] | Bit-rate [kb/s] |
| 22 | 41.0 | 5663.3 | 40.9 | 5870.7 | 3.5 | 26 | 38.8 | 3054.9 | 38.7 | 3190.6 | 4.3 | 30 | 36.8 | 1770.2 | 36.7 | 1860.2 | 4.8 | 34 | 34.8 | 1071.3 | 34.7 | 1137.0 | 5.8 |
