....that edit history contains a wealth of useful information and the video authoring system should exploit it to simplify or even avoid subsequent complicated pixel level processing. The goals of the Zodiac project are to demonstrate the usefulness of a home grown multimedia file system called MMFS [16] in supporting multimedia application development and to verify the hypothesis that recording and analyzing edit operation history could provide useful information about the composed media streams that would otherwise be difficult to come by. Like existing video editors, Zodiac is an interactive ....
....writing the new frame as the i 1 th frame, and then appending the frames just read in to form the rest of the file. In the worst case, this leads to the whole file being read and re written. For large video files, the response time for this simple editing operation is unacceptably long. MMFS [16] is derived from FreeBSD 2.1, and is designed to support interactive multimedia application development. It features an efficient support for inserts and deletes at a small cost of storage space overhead, which could be further reduced by periodic compaction. Two new system calls mminsert and ....

....that include an extra argument mminfo, which is used for that purpose. Other system calls for adding removing strands from an MM file, and for inserting deleting data from strands, are also provided to support multimedia development environments. Further details of the MMFS API can be found in [12]. 3.1 Prefetching A significant metric for file system performance is the response time for synchronous read operations. Because of the real time nature of multimedia accesses, poor response time is visually or audibly perceived as an indicator of poor QoS. Significant gains in response time ....
....data, MMFS can perform the mminsert and mmdelete system calls by initiating a few data I O operations and reorganizing the inode block pointers. Due to considerations of space, details of its implementation and evaluation are not presented in this paper. A complete description can be found in [12]. 4 Performance evaluation The experiments presented here were performed on multimedia data residing entirely on a local IDE disk of a stand alone Pentium 90 PC. We compare the performance of MMFS with that of the VFS UFS implementation (referred to as UFS) of FreeBSD 2.0.5. Since the main point ....
