Abstract: A high degree of data availability is required to ensure QoS in distributed video server environments. In this paper, we propose an algorithm for fault tolerant data placement in a distributed video server that determines the placement of video objects so as to ensure continuity of video requests in the event of node failures. Our performance studies indicate that object distribution strategies have a significant impact on the video placement process.

A Web-based interactive system for scientific simulations takes the simulation and the generated data to the World Wide Web, and thus increase the usability of the system by allowing remote users to view the simulations, to interact with the stimulation engine, to re-configured the underlying models, and to share the simulation with other users around the globe. The design of a web-based visualization system is discussed in this paper. Features that have been implemented and those yet to be implemented in this on-going project are both examined. The paper is concluded with a general discussion of extending the Web-based visualization system into a virtual laboratory.

With new tools for advanced coding efficiency, such as global motion compensation and quarter-pel motion compensation, the newly defined visual MPEG-4 Advanced Simple (AS) Profile targets in particular the increasingly important field of streaming video applications in the promising 1–2 MBit/s range. Based on an analysis of MPEG-4 AS profile bitstream statistics, the implementation on a programmable multimedia processor platform is described, achieving real-time decoding performance for ITU-R 601 resolution video.

The proliferation of multimedia information sources and the availability of large capacity consumer storage devices, raise the need to present video in compact forms so that users can effectively access interesting parts to watch. Aiming at an implementation in consumer electronics products and targeting to non-IT-expert users, an innovative user-friendly tool for video browsing and retrieval has been developed. The color browser enhances conventional slide-bars by embodying information about the video content in its colored background. It exploits low level features, like the dominant colors or the volume of the sound-track, automatically extracted from the digital video streams to allow intuitive access and content-driven navigation through unstructured video sequences.

User interface is a mean to an end —its primary goal is to capture user intent and communicate the results of the requested computation. On today’s devices, user interaction can be achieved through a multiplicity of interaction modalities including speech and visual interfaces. As we evolve toward an increasingly connected world where we access and interact with applications through multiple devices, it becomes crucial that the various access paths to the underlying content be synchronized. This synchronization ensures that the user interacts with the same underlying content independent of the interaction modality — despite the difference in presentation that each modality might impose. It also ensures that the effect of user interaction in any given modality is reflected consistently across all available modalities. We describe an application framework that enables tightly synchronized multimodal user interaction. This framework derives its power from representing the application model in a modality-independent manner, and by traversing this model to produce the various synchronized multimodal views. As the user interaction proceeds, we maintain our current position in the model and update the application data as determined by user intent, then reflect these updates in the various views being presented. We conclude the paper by outlining an example that demonstrates this tightly synchronized multimodal interaction, and describe some of the future challenges in building such multimodal frameworks.

We describe a novel compressed domain (MPEG-2) method to achieve video security and copyright protection in a broadcasting or a multicasting environment. The proposed method is an efficient solution for resolving the conflicting requirements of single copy transmission for broadcasting and multiple unique copies for copyright protection by the broadcaster. The new method supports dynamic join and leave and it relies upon robust invisible watermarking, masking and conditional access techniques to achieve the desired result.

In this paper we propose an audio feature for TwinVQ audio retrieval. For making effective audio database, we consider that these two techniques (compression and feature extraction) are dealt with on one platform. The proposed audio feature satisfies the following requirements: 1) independent of bit rate; 2) extractable from compressed data without decoding; 3) computable in the framework of TwinVQ. We show that the autocorrelation coefficient is theoretically independent of bit rate and confirm experimentally that the feature computed from CD audio data is actually independent of bit rate.

The on-demand multicast [1] is a novel scheme to reduce the video delivery cost for the streaming video applications. Unlike the conventional multicast, this scheme enables the transmission of the multicast data to multiple recipients at distinct times. This property is important for the streaming video applications since the users usually access the video program at different times. To deliver the same multicast data to the recipients at distinct times, the on-demand multicast scheme temporarily caches a sliding window of the incoming stream on a router (or a proxy) and then forwards it on different links at distinct times to generate timevariant outgoing streams. By carefully scheduling the departure time on each router's outgoing streams, a video stream can be distributed to the recipients at their expected times. Based on this scheme, this paper presents three routing algorithms on an asymmetric transmission network model, such as cable systems and ADSL systems. The simulation results indicate that our algorithm offers an outstanding performance in reducing the number of multicast streams and the network bandwidth. In addition, our simulation results are valuable to plan the system resources when deploying the video-on-demand systems.
