The paper presents a work in the field of ‘mixed reality boundaries’ applied to the visualization of museum collections in order to display the collections ‘live’ as a way to extend virtually the preservation areas of museum collections. To achieve this goal, it was set out to integrate several virtual-studio techniques with multicasting IP in the web and the ‘tectonics’ of museums architecture were also redesigned to turn this sort of new infrastructure into what will be a new typology of mixed architectures for museum preservation areas. Dynamic lighting for Chroma-keying techniques were adapted to the real time applications and a MR J3D collision tool was added to the remote motion control of the video camera´s 3d scene live navigation.
