Recent advances in wireless mobile computing, digital library, and distributed multimedia technologies are stimulating the development of mobile multimedia digital library systems ( M2DLS) that allow mobile clients to access multimedia material anywhere and anytime over a cellular radio network. This paper addresses the problem of providing synchronized multimedia retrieval in these sys- tems. An efficient inter-media synchronization scheme called wireless prioritized feedback (WPF) for mobile multimedia on-demand retrieval in digital library systems over CDMA cellular radio networks in the absence of synchronized clocks is presented. In the WPF scheme, base stations use preferential lightweight message called feedback units transmitted by mobile mediaphones to detect and correct asynchronies. The algorithm is described with pseudo code, and experiments are described to demonstrate the efficiency of WPF. 展开更多

The China-US Million Book Digital Library Project (Million Book Project) is an intemational cooperation program between China and the US. However, one million digitized books are considered not to be the ultimate goal of the project, but a first step towards universal access to human knowledge. In particular, there are four challenges about the new way to analyze, process, operate, visualize and interact with digital media resource in this library. To tackle these challenges, North China Centre of Million Book Project (in Chinese Academy of Sciences) has initiated several innovative research projects in areas such as multimedia content analysis and retrieval, bilingual services, multimodal information presentation, and knowledge-based organization and services. In this keynote speech, we simply review our work in these areas, and argue that by technological cooperation with these innovation research topics, the project will develop a top-level digital library platform for the million book library. 展开更多

Institutional repositories are essential research infrastructure for research-based universities. A properly dimensioned institutional repository has the potential to increase research impact and enhance the visibility of an institution through its scholarly outputs. The aim of the study is to design and develop a web-based digital repository for scholarly materials and publications in a tertiary institution. The motivation for carrying out this project is to provide a lasting solution to the need for an effective, efficient, reliable and easily accessible system for storing and retrieving scholarly materials, which will make study and research work less cumbersome and stressful for academic staff and students, thereby enabling them to easily carry out their day-to-day activities, especially as it concerns obtaining relevant scholarly information quickly. The system will be developed using open source software and OOADM (Object Oriented Analysis and Design Methodology). Findings obtained from system validation tests show that the system is a viable solution to the major challenges encountered in the management and sharing of scholarly information at the institution. 展开更多

With the advent of digital media era, the application of digital media has become the focus and breakthrough of the reform of aesthetic education teaching in colleges and universities. Digital media has changed the art itself and the teaching methods of aesthetic education in colleges and universities. Aesthetic education, as an important part of quality education, has been paid more and more attention in Colleges and universities. However, due to insufficient ideological awareness of students, high employment pressure, narrow content of aesthetic education and single evaluation system, the effect of aesthetic education on the improvement of college students' quality is not obvious. Digital multimedia technology has the characteristics of intuition, strong visual impact and large amount of information. It is an important means to expand art teaching resources. How to effectively use teaching software and courseware to implement digital multimedia classroom teaching has become a new problem worth exploring in college aesthetic education teaching. 展开更多

Channel equalization plays a pivotal role within the reconstruction phase of passive radar reference signals.In the context of reconstructing digital terrestrial multimedia broadcasting(DTMB)signals for low-slow-small(LSS)target detection,a novel frequency domain block joint equalization algorithm is presented in this article.From the DTMB signal frame structure and channel multipath transmission characteristics,this article adopts a unconventional approach where the delay and frame structure of each DTMB signal frame are reconfigured to create a circular convolution block,facilitating concurrent fast Fourier transform(FFT)calculations.Following equalization,an inverse fast Fourier transform(IFFT)-based joint output and subsequent data reordering are executed to finalize the equalization process for the DTMB signal.Simulation and measured data confirm that this algorithm outperforms conventional techniques by reducing signal errors rate and enhancing real-time processing.In passive radar LSS detection,it effectively suppresses multipath and noise through frequency domain equalization,reducing false alarms and improving the capabilities of weak target detection. 展开更多
