A multimedia streaming server and an Interconnection Method of multimedia streaming system and multimedia database

摘要

PURPOSE: A server for supplying a multimedia streaming and a method for interlocking a streaming system and a multimedia database system in the device are provided to improve a reliability of a system by managing information of multimedia data and multimedia reproduction data in a database, thereby overcoming inconsistency between information data and multimedia reproduction data. CONSTITUTION: A streaming system(100) transmits multimedia data to a streaming client. A multimedia database system(200) transmits stored multimedia data to the streaming system(100). A shared memory(350) temporarily stores data for transmitting multimedia data in the multimedia database system(200) to the streaming system(100). A message queue(300) transmits and receives a message between the streaming system(100) and the multimedia database system(200). The message queue(300) exists in a stack which is a temporary storing memory in a streaming server. A transmission managing unit(130) packetizes media data in accordance with a protocol for transmitting multimedia data to the streaming client. A media managing unit(120) reads multimedia data from the shared memory(350), decodes the read multimedia data, and transmits the multimedia data to the transmission managing unit(130). If a streaming is requested from the streaming client, a database connector(110) creates a corresponding multimedia streaming session and transmits a task message to the multimedia database system(200). After terminating a streaming task, the database connector(110) deletes a streaming session. A database server(200) includes multimedia data and stores multimedia data requested from the streaming system(100) in the shared memory(350). A media client(210) interprets a message transmitted from the database connector(110) and requests that the database server(200) executes a corresponding task.
