Abstract

This chapter describes and explains common as well as less common distortions in modern video coding, ranging from artifacts appearing in MPEG-2 Video, MPEG-4 Part 2, H.264, and VC-1 to scalable and multi-view video coding based distortions, including the proposals for next generation video coding (NVC). In addition to a discussion about avoiding these artifacts through encoder-side measures, a state-of-the-art overview of their compensation at the decoder side is given. Finally, artifacts emerging from new sophisticated coding tools in current and upcoming video coding standards are discussed.
