As the Web technologies and wired/wireless network are improved and various new multimedia services are introduced recently, need for searching multimedia including video data has been much increasing, The previous approaches for multimedia retrieval, however, do not make use of the relationships among semantic concepts contained in multimedia contents in an efficient way and provide only restricted search results, This paper proposes a multimedia retrieval system exploiting semantic relevancy of multimedia contents based on a domain ontology, We show the effectiveness of the proposed system by experiments on a prototype system we have developed. The proposed multimedia retrieval system can extend a given search keyword based on the relationships among the semantic concepts in the ontology and can find a wide range of multimedia contents having semantic relevancy to the input keyword. It also presents the results categorized by the semantic meaning and relevancy to the keyword derived from the ontology. Independency of domain ontology with respect to metadata on the multimedia contents is preserved in the proposed system architecture.

Many researches are actively doing for digital implementation of traditional architectural heritage using multimedia and virtual reality technologies. In addition, various attempts are progressed to utilize the digitally implemented traditional architectural heritage as "contents." Nowadays, the digitally implemented traditional architectural heritage can be displayed on through the Internet and/or many multimedia appliances by these attempts. Recently, virtual reality technology, especially augmented reality technology, begins to grab the attention for digitally implementing architectural heritage. Augmented reality is a technology that makes possible to show the overlapped contents by piling up the virtual objects on the real world. Many studies for augmented reality are progressed because it has an advantage in interacting with virtual objects and information. This study proposes the method of digital implementation of traditional architectural heritage by using augmented reality technology. We presented the method and process of digital implementation of traditional architectural heritage with augmented reality technology. Moreover, digitally implemented traditional architectural heritage with augmented reality is compared with the contents implemented by other computer technologies. We, also, presented how to utilize the traditional architectural heritage contents by using augmented reality.

With the advance in digital technologies and the increasing prevalence of high quality multimedia contents, there is a growing user demand for multimedia devices, such as mobile phones, digital TV, PMP, digital camcoders, digital cameras. Such devices provide various services associated with multimedia file manipulation, including multimedia contents playback, multimedia file editing, etc. Conventional file systems exhibit a performance-related drawback that requires considerable amount of time and disk I/Os in order to store large-sized edited multimedia files. This paper proposes a fast, efficient writing technique for large-sized edited multimedia files by using data block sharing with adjustment of inode block pointers. Our experiments show that the proposed scheme not only improves write performance of the Ext3 file system on average by 16 times with various types of edited multimedia files, but also reduces consumed disk space dramatically through the data block sharing.
