Highway (QCIF)







GoP Dependency Evaluation


On the pages linked at the left we present statistics related to several different GoP-structures at constant quantization settings. These results can be used to compare different network conditions with suitable GoP-structures. We employed the GoP-schemes stated below on the QCIF video sequence Highway at a constant quantization setting of 30, which produces a medium PSNR at moderate frame sizes.

In the future, we plan to continue evaluation of different sequences and quantization settings.
