摘要： 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.

摘要： Provided are a method for providing contents information in a video on demand (VOD) service and a VOD service system implemented with the same. The VOD service system includes a transmitting unit, a contents storing par, a contents producing unit, and a controlling unit. The transmitting unit receives a VOD service request from a VOD client through a network and transmits data corresponding to the request to the VOD client. The contents storing unit stores moving picture contents to be provided. The contents producing unit produces representative moving pictures each for the corresponding moving picture content and configures an initial screen obtained by combining the representative moving pictures together. The controlling unit transmits the initial screen including the representative moving pictures of the individual moving picture contents when the VOD client makes a request to provide a list of the moving picture contents to be provided through the transmitting unit.
