The proceedings contain 85 papers. The topics discussed include: searching and filtering of audio-visual information: technologies, standards, and applications;dequantization bias for JPEG decompression;a probabilistic image model for smoothing and compression;application specific image compression forvirtual conferencing;media-independent watermarking classification and the need for combining digital video and audio watermarking for media authentication;a spatial digital video watermark that survives MPEG;overview of interference cancellation for CDMA wireless systems;wireless multimedia communication through multichannel multipoint distribution service;advanced signal processing for wireless multimedia communications;simple collosion-secure fingerprinting schemes for images;and digital watermarking using inter-block correlation: extension to JPEG coded domain.
To guarantee quality of service (QoS), the requirements of video transmission, such as delay and cell loss rate (CLR), are very stringent. These constraints are difficult to meet if high network utilization is desired...

Multidimensional databases are used for online analytic processing (OLAP) applications with great success. We introduce a method of using OLAP techniques on a text collection: combining text searching and ranking tech...

The issues of video coding based on exceptionally suitable for SHD format Shapiro (1993) EZW (embedded zero wavelet) algorithm is discussed. The main aspect is a possibility of building a real time system which is abl...

Digital watermarking schemes have been discussed to solve the problem associated with copyright enforcement. As a digital watermarking, we proposed a method using inter-block correlation of DCT coefficients. It has th...

In distributed systems uneven arrival of the tasks may overload few hosts keeping the rest of the hosts lightly loaded or even idle. This results in overall poor system performance in spite of the system capabilities....
The paper discusses the requirements for authoring methodologies for large multimedia systems to be used for technical documentation in the domain of 'safety critical' industries. In such industries the docume...
