In this work we compare non-scalable video coding with data partitioning using H.264/AVC under similar application and channel constraints for conversational applications over mobile channels. For both systems optimized rate allocation and network feedback has been applied. From the experimental results it is observed that based on the average PSNR the non-scalable system outperforms the data partitioning system. However, with the data partitioning system the percentage of entirely lost frames can be lowered, and the probability of poor quality decoded video can be reduced.
