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...
Summary form only given. In this paper, an error resilient JU-DFMC is proposed for video transmission over error-prone channels. In the proposed error resilient JU-DFMC, a new error resilient prediction structure of DFMC is firstly presented. The LQF can adaptively select reference frame according to different packet loss rate. Then the MB information is divided into two partition header information...
In dual frame motion compensation (DFMC), one short-term reference frame and one long-term reference frame (LTR) are utilized for motion compensation. The performance of DFMC is heavily influenced by the jump updating parameter and bit allocation for the reference frames. In this paper, first the rate-distortion performance analysis of motion compensated prediction in DFMC is presented. Based on this...
In dual frame video coding, one short-term reference frame (STR) and one long-term reference frame (LTR) are available for motion compensation. The STR is the previous frame of current frame. The LTR remains static for a few frames, and then jump forward. In this paper, for different GOP length and bits allocation of the LTR, the coding performance of dual frame motion compensation is analyzed. The...
