A transmitting process of a sequence of holograms describing 3-D moving objects over a communicating network system is presented. A sequence of holograms involves holographic information of 3-D moving objects recorded as fringe patterns. In this process, holographic information recorded in the holograms is transformed into bit stream data, and then is transmitted over the Internet. We call this process a "network streaming technique." It is shown that by applying this network streaming technique, holographic data of 3-D moving objects are transmitted in high quality, and a relatively good reconstruction of the holographic images is performed. Moreover, it suggests that if this network streaming technique is employed together with MPEG-4, a new transmitting process for holographic information of 3-D moving objects may be rigorously developed over network systems, and will play a very important role in this field.
