摘要： Provided is a real-time streaming protocol (RTSP) based progressive streaming method. The progressive streaming method based on a real-time streaming protocol, wherein a server transfers SDP information and performs streaming of a contents file to a client connected, the method including the steps of: a) if a “pause” request message is received from the client, transmitting a “pause” response message including the number of TCP packets already transferred to the client, and pausing streaming of the contents file; and b) if a “replay” request message including the number of the TCP packet to be transferred is received from the client, transmitting a “replay” response message and restarting transmission of the TCP packets from the next TCP packet to the TCP packet transferred to the client before the contents file is paused.

摘要： An HTTP based video streaming apparatus and method of a mobile communication system is disclosed. A memory, such as a storing disk, stores content files received from a server of a transmitting party, a random access searching unit searches the random access point in the memory and transmits a content file request message to the transmitting server if the random access point does not exist in the memory, and a display unit displays the files from the random access point. Therefore, HTTP streaming service from a random point required by a user can be provided when the streaming has begun, and the random access function can be supported by even if the part required by the user has not yet been transmitted to receiving party.
