It consists of two indispensable parts SMART video coding and SMART video streaming. The SMART video coding part is an efficient DCT-based universal fine granularity scalable coding scheme. Since the SMART video coding scheme adopts multiple-loop prediction and drifting reduction techniques at the macroblock level it can achieve high coding efficiency at a wide range of bit rates. More importantly it provides all sorts of scalabilities that is quality temporal spatial and complexity scalabilities in order to accommodate heterogeneous time-variant networks and different devices. The SMART video streaming part is a transport scheme that fully takes advantages of the special features of the scalable bitstreams. An accurate .
