Abstract : Multimedia is a combination of text, graphics, animation, audio and video, converted from different formats into a uniformat digital media and hypertext is non-sequential writing or reading. Multimedia prepared in hypertext environment is called Hypermedia. This paper describes multimedia, its applications and limitations in general. The need for multimedia in libraries and its use for various applications in US and Europe such as multimedia library information kiosks, walk-through programmes, training, digital libraries, multimedia databases, multimedia catalogues, multimedia library collections, geographical information systems, electronic publishing, etc are also discusied.

Abstract : Multimedia presentations have become a favourite medium for conveying ideas, messages, project reports, products’ information; describing marketing strategy; presenting annual growth, and so on in business/commercial houses. It is also being used a lot in academics and entertainment. Definitely the addition of multimedia effects certainly gives lively and interactive appearance to any presentation. This article describes application of multimedia and use of it in libraries. The various aspects of managing a multimedia presentation are discussed in detail. Planning is one of the most important part in management of any activity. The various other factors like analysis, design, development, implementation during the preparation of any multimedia presentation to be considered are discussed. Organising the multimedia team is also a very important part of management of any multimedia activity. Its various members and their roles are described.

Abstract : This article considers multimedia from three view points. The first comes from a science theory where the definition of the term and of the environment associated with it is defined. The second point of view is concerned with the knowledge acquisition through multimedia systems and the educational and psychological aspects are considered. The third point of view gives concrete instructions for designing multimedia systems.

Abstract : Multimedia digital libraries involve diflerent types of data objects such as text, audio, video and images. Most of these data objects are very large in size and accessing them in a distributed environrnent causes a transmission delay due to the vast amount of network traffic. Compressing these data objects before transmission, can reduce the response time, although it would mean a reduction in the quality of the output data. If the application doesn't demand a high quality output, data compression can be an acceptable means of reducing transmission time over the internet or other distributed environments. The loss of quality would be proportional to the amount of compression applied to individual data objects. Therefore different quality levels (browsing levek) can be achieved depending on how the data will be used. A lower quality level could be used for general browsing of data whereas a higher quality level could be used where the output data has to be further processed and analysed. The behaviour of images when coinpressed using various conlpression techniques was studied and it was observed that different images require different amounts of compression to reach the same quality level. This result allowed us to classify images into different classes, based on their compression behaviour. In this paper, we identify a set of rules to calculate a near optimal compression ratio to achieve a given level of image quality. We also explain how this set of rules can be incorporated i ~ t odig ital libraries with nlultiple levels of browsing, to achieve a faster response time.
