Abstract
A method and apparatus provide for improving signal quality. The method includes receiving a first media signal, such as a video signal, in a first format, such as 1080p. The provided video signal is one that is created by upsampling a video signal recorded in a format having a lower sampling rate. The method also includes obtaining a second signal indicative of error within the first media signal. The second signal is in a second format, such as the format having a lower sampling rage in which the video signal was recorded. The signal is processed to place the second signal in the format of the first signal. Then, the estimated error signal is combined with the original signal to arrive at an error corrected output.
