Description
Summary:This paper proposes a new error resilient video coding scheme using the matching pursuit (MP) residual coding and the multiple description coding. A conventional discrete cosine transform-based video coding scheme introduces undesirable blocking artifacts at low bit rates. MPs for residual coding has been developed to overcome the disadvantage. The parameters obtained after MP, called atoms, are encoded into two balanced descriptions using scalar quantizers. The two descriptions are respectively transmitted over two separate channels. If both descriptions are received, a high-quality reconstruction can be obtained, however, if either description is lost, a low-quality, but acceptable, reconstruction can be acquired.
