US Patent 7853981 Multimedia streaming service system and method

A multimedia streaming service system is provided that includes a VOD server to sequentially transmit a header (moov) and media data (mdat) of MP4 contents in a TCP packet and a client to transmit a streaming service request signal in HTTP to the VOD server. The client may accumulate the media data (mdat) received from the VOD server in a decoder buffer for a predetermined time, and reproduce the data on a real time basis. A guaranteed rate of QoS may be enhanced as compared to an RTP/UDP-based streaming method. A service delay time may be reduced as compared with a TCP-based downloading method, thereby implementing contents on a real time basis.
