Video quality assessment in real time is a critical requirement for channel evaluation and codec optimization in mobile multimedia system. However, most proposed approaches for video quality assessment need reference sequences, which is quite impossible in real time multimedia communications especially in wireless and IP video services. This paper proposes a novel no-reference video quality assessment method. By comparison of the extracted watermark embedded in transmitted video with the copy of original watermark in the destination, we can assess all reconstructed video quality without any original reference video sequences. Simulation results conclusively demonstrate that our method offers no-reference video quality assessment with little channel overhead and can be applied to real time multimedia systems.
