摘要：
A system and method for video quality assessment includes utilizing codec auxiliary information related to the encoding and decoding process to enhance performance of picture quality assessment. In a video transmission system, video quality assessment can be accurately performed in real time with reduced computational load upon the client. In particular, the server performs first picture quality assessment and sends the assessment result to the client, and the client performs second picture quality assessment only when a transmission error occurs to reduce the computational load on the client.
