What is Multimedia? Multimedia: a working definition A combination of two or more categories of information having different transport signal characteristics Typically, one medium is a continuous medium while another is discrete Image, audio, video and graphics are examples of media
Images Some Issues Is the image as high-quality as I need? Is the image efficiently stored and transmitted? Can the image be retrieved by its content?
Videos Some issues How are the temporal relations between the media represented? What do I need to stream video across the network? Are the different media synchronized? How can I describe a video retrieval request like a query?
What is a Multimedia System? A system that involves: generation representation storage transmission search and retrieval delivery of multimedia information production/authoring tools compression and formats file system design networking issues database management server design, streaming
