Abstract
A method for transferring multimedia information in a system including a primary site 101 and at least one satellite site 102 coupled to the primary site 101 by a transmission medium 103. Information defining each of a selected plurality of objects composing a multimedia presentation is compressed at primary site 101 using a compression/decompression protocol corresponding to a type of each of the objects. The compressed information is transferred to satellite site 102 from primary site 101 via medium 103. Scene information describing the multimedia presentation to be made from the objects is also transferred from primary site 101. The compressed information defining each of the objects is decompressed at satellite 102 using the corresponding compression/decompression protocol. The multimedia presentation composed of the selected objects is generated at satellite site 102 from the decompressed information as directed by the received scene information.
