Abstract:
1. A multimedia streaming service system comprising: a video on demand (VOD) server to transmit a header and media data in at least one transmission control protocol (TCP) packet; and a client that includes a memory, a decoder and a decoder buffer, the client to transmit a streaming service request signal in Hypertext Transfer Protocol (HTTP) to the VOD server, the client to receive the header and store information from the header in the memory for a first predetermined time, the header including information of a decoder operation standby time and information of a retransmission service standby time, wherein after completely receiving the header in the memory, the client to accumulate the media data received from the VOD server in the decoder buffer for a second predetermined time that begins at an end of the first predetermined time, wherein the client to provide the media data accumulated in the decoder buffer to the decoder after the decoder operation standby time from the end of the first predetermined time for reproduction of the data on a real time basis, and the client at a same time to accumulate the media data transmitted in the at least one TCP packet from the VOD server into the decoder buffer, wherein the second predetermined time is based on an addition of the decoder operation standby time that is received by the client within the header and the retransmission service standby time that is received by the client within the header, wherein the decoder operation standby time corresponds to an amount of time from when the media data reaches the decoder buffer to a time point when the decoder starts decoding, and the retransmission service standby time corresponds to extra time for retransmitting a lost TCP packet, and the decoder buffer accumulates the media data for the second predetermined time that includes the added total of the decoder operation standby time and the retransmission service standby time after the end of the first predetermined time.
