  • Patent number: 9699481
    Abstract: A technique is provided for processing decoded video data to mask visual compression artifacts resulting from video compression. In accordance with this technique, a hardware block is provided for generating and adding random noise to the decoded video stream. In one embodiment, a random number is generated for each pixel of the decoded video data and compared against one or more threshold values to determine a threshold range. In such an embodiment, a noise addend value is selected based upon the threshold comparison and summed with the current pixel. While the present technique may not eliminate the compression artifacts, the addition of random noise renders the compression artifacts less noticeable to the human eye and, therefore, more aesthetically pleasing to a viewer.
