artifact

Unintended and unwanted distortions or other aberrations in reproduced audio or video due

to transmission errors or signal processing operations. Artifacts often result from the use of lossy compression algorithms at high compression ratios. Artifacts in video images can manifest as jagged blockings or a tiling effect known as aliasing, banding of colors, white spots, and even dropped frames. See also aliasing, compression, distortion, lossy compression, and signal.
