Abstract

In addition to the large data size requirement and real-time constraint in continuous media, future video applications such as video editing demands the flexible storage placement and the random access capability on the videoframe level. To offer efficient buffering schemes and flexible storage placement for supporting random access, we present two buffering schemes: the two-buffer scheme and the k-buffer compensation scheme. The two-buffer scheme requires only all the frames in a block to be stored consecutively while providing random access between blocks. However, this intuitive buffering scheme potentially requires a large block size and buffer space. The k-buffer compensation scheme is proposed to resolve this large buffer space requirement by using more than two buffers and requiring a minimal number of blocks randomly placed in each cylinder. Experimental measurement results reveal the significant improvements on the buffer-size reduction and placement flexibility by using the k-buffer compensation scheme
