System and method for real-time video quality assessment based on transmission properties

A video quality assessment apparatus comprising:

• a sender unit for accepting source moving images and outputting coded data via a transmission network for transmitting the coded data from the sender unit;
• and
• wherein the sender unit includes a video encoder for encoding the source moving images, and a first video quality evaluator for performing first picture quality assessment using the source moving images and encoded moving images, and
• wherein the first video quality evaluator employs at least one of a full reference scheme or reduced reference scheme, and utilizes codec auxiliary information of the video encoder.

A video quality assessment method for a system that comprises a sender unit for accepting source moving images and outputting coded data, a transmission network for transmitting the coded data from the sender unit, and a receiver unit for receiving the coded data from the transmission network, decoding the coded data into moving images, and performing picture quality assessment using the decoded moving images, the method comprising:

• encoding source moving images input to the sender unit, by a video encoder of the sender unit;
• performing picture quality assessment using the source moving images and encoded moving images, by a first video quality evaluator of the sender unit;
• decoding the coded data received through the transmission network from the sender unit, by a video decoder of the receiver unit;
• and
• performing picture quality assessment using receiver side information from the video decoder by a second video quality evaluator of the receiver unit.
