A content providing system and method for a streaming service are provided. The content providing system is connected to at least one of wired/wireless terminals and a wide area server. The content providing system includes at least one of local servers and a manage node. The local servers store contents received from the wide area server and provide context index information. The managing node manages the context index information by the contents stored in the local servers and the wide area server, and determines a storing location of a corresponding content from the context index information if a content request message is received from a terminal. Also, the managing node transmits the requested content to the terminal through a wired/wireless Internet network by transmitting a content-transmission message to local servers having the corresponding content or the wide area server.

The present invention relates to a mobile communication terminal and operating method thereof in which data sync error occurring when multimedia data is played can be compensated for. The mobile communication terminal includes a speaker through which played multimedia data is output, a display unit on which text data are output, an multimedia controller that analyzes and plays multimedia data, compensates for error of an output time, which is generated as the multimedia data are played, and outputs compensated text data, and a controller that manages data when multimedia data is played, and controls the driving of the speaker and the display unit. Temporal error between output time information and an audio signal that is actually output, and proportional temporal error occurring in proportion to an output time are calculated. Temporal information is compensated for based on the calculated temporal error and proportional temporal error.
