Abstract: Provided are a fast channel change apparatus based on multiple multicasts communication in an IPTV network, and a method thereof. In the fast channel change system, after separately generating at least one multicast stream obtained by applying different time delays respectively to original multicast stream to be broadcast, a channel server dynamically analyzes information regarding the at least one multicast stream. After querying the channel server for information regarding an optimal multicast stream and receiving the response to the query, a user terminal joins a multicast group on the optimal multicast stream through a router. After a predetermined time is elapsed, the user terminal joins a multicast group of the original multicast stream. Thus, it is possible to easily and inexpensively embody a fast channel change function network based on multiple multicasts communication in an IPTV network.

Abstract: Provided is a method of obtaining spatial images on demand. The server segments a spatial image into a plurality of regions to detect an isolated region whose continuity with peripheral regions is less than a threshold value, generates geographic information corresponding to the detected isolated region, and generates a capture request message including the generated geographic information. In addition, the capture request message may be transmitted to at least one terminal using unicast scheme, a multicast scheme, an anycast scheme, or a broadcast scheme. The capture request message may comprise a capture condition value such as a capture direction, a capture angle, a capture time, a zoom information and an exposure value. At least one terminal which meets the capture condition value within the capture request message transmits a captured image to the server.
