Time synchronizing apparatus and method in embedded multi-media system, and multimedia player comprising the same apparatus

摘要

PURPOSE: A time synchronizer in an embedded multimedia system for accurately synchronizing audio and video with the soft regeneration of a video screen is provided to make the audio/video synchronization of the completion of software in an embedded multimedia system. CONSTITUTION: A timer generation unit(120) is created the time based on a CPU(Central Processing Unit) timer(200). A time correction unit(140) revises the time of the timer generation unit based on an audio timer(300). A time output unit(150) receives the corrected time. The time output unit outputs the corrected time to a reproduction unit. A control unit(130) controls the timer generation unit and the time correction unit.
