Abstract

Recently as the user request on NoD (News-on-Demand) is largely increasing, there are a lot of researches to fulfill it. However, because of short life-cycle of news video data and periodical change of video data depending on anchor, it is difficult to apply the conventional video storage techniques to NoD applications directly. For this, we design and implement low-level storage manager for efficient storage and retrieval of multimedia data in NoD Services. Our low-level storage manager not only efficiently stores video stream data of news video itself, but also handles its index information. It provides an inverted file method for efficient text-based retrieval and an X-tree index structure for high-dimensional feature vectors. In addition, our low-level storage manager provides some application program interfaces (APIs) for storing video objects itself and index information extracted from hierarchical news video and some APIs for retrieving video objects easily by using cursors. Finally, we implement our low-level storage manager based on SHORE (Scalable Heterogeneous Object REpository) storage system by using a standard C++ language under UNIX operating system.
