摘      要：The use of background memory to improve coding efficiency has gained momentum recently due to the rapid decrease in the cost of memory chips. However, the associated computational costs still pose a problem for real time implementation. The authors propose a coding oriented scene-change detection algorithm and the use of multiple thread background memory to improve the coding efficiency of both scene-change frames and frames between two consecutive scene cuts. The experimental results show that the proposed scheme can improve the coding efficiency in both situations. The improvement is significant for scene-change frames.
