    • In a system and method for dynamically synchronizing a digital soundtrack with a moving picture in motion picture media, the system includes a device for presenting the motion picture media, wherein the motion picture media further includes an analog soundtrack. The digital soundtrack further includes a variable delay to compensate for the distance between a frame in the moving picture and a portion of the digital soundtrack corresponding thereto. A synchronizing device is correlated to a digital soundtrack pickup and an analog soundtrack picture in a feedback loop. A processor in the synchronizing device is adapted to process the digital soundtrack and the analog soundtrack to generate a control signal based on the difference between the location of a transient reference in the analog soundtrack and the same transient in the digital soundtrack, and to use the control system to adjust the variable delay in the digital soundtrack for synchronization thereof.
    • 在用于在运动图像媒体中动态地同步数字音轨与运动图像的系统和方法中,系统包括用于呈现运动图像媒体的装置,其中运动图像媒体还包括模拟声轨。 数字音带还包括可变延迟以补偿运动图像中的帧与对应于其的数字声轨的一部分之间的距离。 同步装置与反馈回路中的数字配乐拾取器和模拟声轨图像相关。 同步装置中的处理器适于处理数字声轨和模拟声轨,以基于模拟乐曲中的瞬时参考的位置与数字乐曲中的相同瞬态之间的差异来产生控制信号,并且使用 控制系统来调整数字音轨中的可变延迟以进行同步。
