The analysis results show that lossy compression has a detrimental effect on the integrity of practical search and retrieval schemes that utilize the low level audio descriptors. Methods are then proposed to reduce the detrimental effects of compression in searching schemes. These proposed methods include multi-frame searching and machine learning derived prediction. The proposed mechanisms greatly reduce the effect of compression on the set of MPEG-7 descriptors; however, future scope is identified to develop new audio descriptors that account for compression effects in their structure.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

Providing a required QoS as well as modeling multimedia traffic has been a challenging task. In this work, we transcode multimedia data to cater for low bandwidth availability and different end-user requirements. We propose a protocol architecture which has been developed by the amalgamation of well-known components and that would provide guaranteed multimedia communication over the Internet. We model multimedia traffic using the M/Pareto distribution in an attempt to represent realistic traffic pattern. We use semantics of multimedia data-streams for transcoding to avoid network congestion and to ensure optimal use of network resources. The impact of transcoding the multimedia data to suit it to the network load and the end user requirements is also studied. The simulation results are presented and compared.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat.

We propose an efficient buffer management mechanism such that the memory requirement is reduced by 50%. This is approached by two steps: first we use an ST scheme to minimize the transmission buffer in a slave node by allowing dynamic sharing between frames in one group of picture (GOP). Then we further reduce the buffer space by a dynamic buffer allocation according to image type. The revised parallel decode showed a satisfactory scale-up performance when decoding the high-resolution video formats.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

We present a new broadcasting protocol that assumes that some portions of the video are already preloaded in the set-top-box (STB), and at the same time, requires the user to wait for a fixed-delay before viewing. As a result, there is a trade-off between the size of the consumed local storage, user waiting time, and bandwidth consumption. This trade-off makes this protocol very flexible, in that we can control the consumption of one resource by adjusting the use of the other two. Also, the performance of the proposed protocol is not very far from the theoretical minimum. We also present a heuristic version of the protocol, in which the performance is improved a little.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

An interference cancellation algorithm is proposed that exploits the base-band cyclostationarity properties of the signal, which are induced at the transmitters by means of modulating the symbols with distinct polynomial phase sequences. In contrast to the method presented in [A.J. van der Veen and L. tong, 2002], the proposed technique docs not require knowledge of the starting time of transmission of the desired signal and can be applied to dispersive multipath channels. Also a practical way of assigning the modulating sequences via the use of a common codebook known to all nodes is proposed, and the impact on local throughput of such scheme is analyzed.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

It represents a set of normative requirements on bitstream for the purpose of avoiding buffer overflow and underflow. In other words, any coded video bitstream shall meet constraints imposed by HRD model. Two HRD models, i.e. the earliest arrival time leaky bucket (EAT- LB) and the constrained arrival time leaky bucket (CAT-LB), have been proposed for the JVT standard jointly developed by ISO/IEC and ITU-T. EAT-LB has the lower initial delay, whereas the CAT-LB model has the lower maximum delay. This paper proposes an improved leaky bucket model called latest arrival time leaky bucket (LAT-LB) so as to achieve the advantages of EAT-LB and CAT-LB simultaneously. The proposed LAT-LB first defines the data transmission schedule according to a set of resume points and stop points, and then derives the HRD parameters according to this schedule. Experimental results demonstrate that the proposed LAT-LB outperforms EAT-LB and CAT-LB in terms of initial delay and maximum delay.","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo.

However, the applicant of MDC to video coding is still problematic because a prediction mismatch problem, called drift, may occur at the decoder when one description is lost. In this paper, we propose a drift free motion-compensated predictive coding method for multiple description scalar quantizers. The proposed method maintains two more prediction loops at the encoder side to produce all possible predictions. Then, the two descriptions are generated from these two additional prediction loops in such a way that the drift can be prevented when only one description is received. By receiving both descriptions, the decoder can still combine these two descriptions in the central prediction loop to improve the video quality. Experimental results show that the proposed method can effectively prevent drift and improve the quality of single-description reconstruction by 0.2-0.8 dB as compared to the method in [A. Reibman et al., 1999].","PeriodicalId":118560,"journal":{"name":"2003 International Conference on Multimedia and Expo. ICME '03. Proceedings (Cat.
