In this paper, auto regressive (AR) model is applied to error concealment for block-based packet video coding. In the proposed error concealment scheme, the motion vector for each corrupted block is first derived by any kind of recovery algorithms. Then each pixel within the corrupted block is replenished as the weighted summation of pixels within a square centered at the pixel indicated by the derived...
Rate control plays an important role in video coding. When jump update dual frame motion compensation (JU-DFMC) is utilized in video coding, two kinds of frames are existed according to bit allocation, one is low quality frame (LQF), the other is high quality frame (HQF). For each current frame (LQF or HQF), one short term reference frame (STR) and one long term reference frame (LTR) are utilized...
