METHOD OF SUPPLYING MOBILE MULTIMEDIA COMMUNICATION USING MULTIMEDIA STREAMING FORMAT

摘要

PURPOSE: A method of supplying mobile multimedia communication using a multimedia streaming format is provided to synchronize audio video caption data to minimize periodically-transmitted control data by using a streaming format for multimedia broadcasting, thereby improving multimedia picture quality and sound quality. CONSTITUTION: A client starts rendering(S1), and lists-up plug-in CODECs(S2). The client downloads an RSF(Rostic Streaming Format) stream(S3), and searches control data for initializing the CODECs(S4). The client checks whether the CODECs exist(S5). If so, the client checks a version of the CODECs(S6). If the CODECs do not exist, the client displays an error message and completes the rendering(S7). The client opens the CODECs after checking the version(S8), and decodes an audio frame as decoding a video frame(S9). The client closes the CODECs(S10), and completes the rendering(S11).
