Abstract :
We present MVC, the proprietary low bit rate video coder developed at Nokia Research Center. This video coder contains three major elements distinguishing it from the current video coding standards. These elements, which prove to be the source of its improved coding efficiency, are: •Motion compensation scheme utilizing affine motion field model, which enables very accurate prediction. •Efficient pixel domain prediction for intra-coded frames utilizing image data from the surrounding reconstructed area. •Powerful Multi-Shape Discrete Cosine Transform (DCT) and Karhunen-Loeve Transform (KLT) based scheme for efficient coding of the residual error. In this paper, we will shortly describe all these three elements and present comparison with H.263 video coder.
