Sažetak
MPEG-4 SNHC requires transmission of object parameters through a bitstream, with a variety of bitstream bandwidth and latency. Especially with complex environments and a large number of transmitters, these requirements might be excessive. Therefore, tools should be provided to decrease the amount of information sent through the bitstream. In this paper, we propose to use in SNHC the dead-reckoning technique that has been successfully used in the networked virtual environments area. The technique is based on extrapolation of the object parameters depending on the last animation parameters received from the transmitter during the update phase. In this paper, we survey the use of the dead-reckoning technique for synthetic objects in MPEG-4 SNHC, particularly simple nonarticulated rigid objects, human faces and bodies.
