In this paper, a methodology for objective evaluation of the quality of video programs, without reference, recording these programs in the users' residence using a video camera is presented. The methodology is based on the use of a digital watermark embedded in the original program. The watermark is invisible to the user, but capturable by the video camera. The recorded video is handled by specific software that evaluates the watermark degradation. The measure of degradation of this watermark is used to estimate the quality of the video broadcasting system. A case study is presented to validate the methodology.
