Hadoop distributed file system (HDFS) was originally designed for streaming access large files, but the access and storage efficiency is low for the mass small files. This paper presents an access optimization approach for HDFS small file based on MapFile: TLB-MapFile. TLB-MapFile merges massive small files into large files by MapFile mechanism to reduce(More)
The latest video-coding standard H.264/AVC, which adopts rate distortion optimization (RDO), can achive better coding efficiency. However, several techniques, such as inter mode and intra mode selection need to check all the prediction modes. So, it will greatly increase computational complexity. In this paper, a fast algorithm based on the quantization(More)
