A system, method, and apparatus for watermarking multimedia content with reduced reference information for perceptual quality of service measurements. The system and method allow the perceived quality of multimedia content to be measured in-service. The system, method, and apparatus achieve these advantages by creating the reference information from the original content and embedding the reference information as a watermark in the original content so that the perceptibility of the reference information to a user is minimized. The original content with the embedded reference information is transmitted to a receiving device where the watermark is extracted from the received signal, and the reference information contained therein is used to determine the perceptual quality of the signal. |
