A framework for scalable delivery of digitized spaces

摘要

We present a framework for scalable delivery of digitized environments. Today's digital museums distribute images, text, sounds, and videos. Our work targets the distribution of a more advanced media type that allows users to independently and interactively explore digitized spaces. We describe a multidimensional and multiresolutional representation that maps directly to a set of communication channels. Clients receive data by subscribing to and unsubscribing from these channels. Client adaptation to current application and network conditions is performed by managing a working set of channels. This mechanism enables distribution of digitized environments to large groups of independent digital museum visitors.
