M-QAM is a modulation technology with high spectral efficiency, due to the property of Gray-coded constellation phasor where different bits have distinct anti-noise ability. Scalable video coding has the ability to transmit partial bit streams thus reconstruct lower video quality according to the channel status to cater for the channel fluctuation. A rate-distortion optimized (RDO) wireless video...
Rate control is an essential technique for video codec designing. For the purpose of smoothing video output quality, more bits should be allocated to the frame with high coding complexity. A novel coding complexity prediction algorithm based on motion extrapolation is proposed, and combined with coding buffer occupancy to determine the frame-layer bit allocation, which could smooth the video output...
In the video coding standard H.264/AVC, various coding tools have been proposed to improve the efficiency of motion compensation (MC). In this paper, the overlapped block motion estimation and compensation (OBME/MC) is applied to the framework of H.264/AVC encoder to further increase the coding performance. Our main contribution is to adapt the overlapped weighting factors to the coding mode of neighboring...
