System and method for artifact removal

摘要

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.

主权项

1. A method of providing signal improvement including:
receiving a first media signal in a first format, the first format resulting from having undergone at least one permutation from an original format, the first format being different than the original format; obtaining a second signal indicative of error within the first media signal, the second signal being in a second format, the second format being different than the first format; applying a second permutation to the second signal to place the second signal in the first format; and combining the first media signal in the first format and the second signal in the first format to produce an error-corrected first signal in the first format.
