For better video qualities, the video encoders usually adopt the process of Rate Distortion Optimization (RDO) that involves the the cost function with the Lagrange multiplier λ to …
This paper presents two low complexity macroblock-level MAD (Mean Absolute Difference) prediction algorithms for H.264/AVC rate control. Both of the algorithms consider the …
In this paper, we propose a real time hardware architecture with low cost for histogram difference calculator to process and low-level extraction in our video abstraction system. …
In the transmission of low bit-rate video bit-stream, a packet loss usually results in whole frame loss, and the frame based error concealment (FBEC) becomes a necessary technique …
In this paper, we present a serial coding method to reduce the bus transition activity and implement error control code to reduce bit error probability. We propose two kinds of …
