Table 1
Two-layer (QCIF-CIF) spatial SVC coding versus single layer (CIF) coding (“SOCCER” video sequence, 30 fps, 300 frames, GOP size is 16).
| Quantization parameters | Single layer (CIF) | QCIF-CIF | Bit-rate overhead (%) | PSNR [dB] | Bit-rate [kb/s] | PSNR [dB] | Bit-rate [kb/s] |
| 22 | 40.9 | 1636.8 | 40.9 | 1713.5 | 4.5 | 26 | 38.6 | 917.2 | 38.6 | 968.8 | 5.3 | 30 | 36.5 | 544.0 | 36.5 | 578.1 | 5.9 | 34 | 34.4 | 332.9 | 34.4 | 357.5 | 6.9 |
