PORTABLE MULTIMEDIA DATA REPRODUCTION DEVICE FOR SYNCHRONIZATION REPRODUCING OF MORE THAN TWO INDEPENDENT MULTIMEDIA DATA AND A REPRODUCTION CONTROL METHOD THEREFOR, AND A SYSTEM FOR SUPPLYING MULTIMEDIA DATA, SPECIFICALLY RELATED TO ADDING COMBINED DATA TO INDEPENDENT DATA TO REPRODUCE AS TRUE MULTIMEDIA CONTENTS

摘要

PURPOSE: A portable multimedia data reproduction device for synchronization reproducing of more than two independent multimedia data and a reproduction control method therefor, and a system for supplying multimedia data are provided to manufacture combined data of audio data or video data for being coupled with independent data such as existing audio data, and to synchronize the combined data with the independent data, thereby enabling a user to easily combine contents. CONSTITUTION: A data storage(218) stores independent data and combined data including synchronization information necessary for synchronization with the independent data. A user input processor(210) receives a user selection related to a reproduction of the independent data and the combined data. A data synchronization controller(220) synchronizes the independent data with the combined data. A data reproducer(202) reproduces the synchronized independent data and the combined data. The data synchronization controller(220) comprises as follows. A data analyzer(208) detects a specific part corresponding to the second identifier among the independent data. A synchronous controller(206) controls such that reproduction times of the independent data and the combined data can be synchronized.
