Low-complexity frame scheduler using shared frame memory for multi-view video coding

Multi-view video coding (MVC) produces more realistic three-dimensional scenes using disparity (or depth) information derived from cameras placed in parallel than mono and stereo video coding. However, the performances such as chip area, power consumption and processing time are dependent on how to schedule the multi-view frames. This paper proposes a low-complexity frame waiting time aware scheduler (WTaS) for faster MVC. In order to reduce the frame memory size for MVC, we design a shared frame memory scheme so that the frame memories of many views can be shared using a smaller frame memory for high frame memory utilization. Experimental results show that the proposed low-complexity WTaS scheduler can reduce the size by 30%~50% without degradation of the processing time.
