Abstract
Method, device and computer program product for estimating quality of a video signal, wherein frames of the video signal are received at receiving means of the device, each frame comprising a plurality of blocks of pixels. A section of a first frame of the video signal, which is correctly received, is used to provide a concealed block for use in place of a block of a second frame of the video signal. A difference measure is determined indicative of a difference between at least some of the pixels surrounding the block in the second frame and the corresponding pixels surrounding the section in the first frame. The difference measure is used to estimate the quality of the second frame of the video signal.
