摘要：

dThis paper presents the results of a quality evaluation of video sequences encoded for and transmitted over a wireless channel. We selected content, codecs, bitrates and bit error patterns representative of mobile applications, focusing on the MPEG-4 and Motion JPEG2000 coding standards. We carried out subjective experiments using the Single Stimulus Continuous Quality Evaluation (SSCQE) method on this test material. We analyze the subjective data and use them to compare codec performance as well as the effects of transmission errors on visual quality. Finally, we use the subjective ratings to validate the prediction performance of a real-time non-reference quality metric.
