    • A method and apparatus for controlling buffering of an audio stream so that audio can be played continuously without stoppage using a minimum amount of buffering are provided. The method for controlling buffering of data includes (a) determining a buffering period of compressed audio data on the basis of a time stamp which corresponds to a packet division unit, by considering the state of a network, (b) calculating a time period where the compressed audio data is to be stored in a buffer, on the basis of the buffering period that is determined in step (a), (c) buffering the inputted compressed audio data in a decoding buffer for the time period that is calculated in step (b), and (d) decoding the compressed audio data that is stored in the decoding buffer when the time period passes in step (c) and storing the decoded audio data in a composition buffer for synchronization with video data.
    • 提供了一种用于控制音频流的缓冲的方法和装置,使得可以使用最小量的缓冲来连续地播放音频而不停止。 用于控制数据缓冲的方法包括:(a)通过考虑网络的状态,基于与分组单元对应的时间戳来确定压缩音频数据的缓冲周期,(b)计算一个时间段, 基于在步骤(a)中确定的缓冲周期,将压缩音频数据存储在缓冲器中,(c)将解码缓冲器中输入的压缩音频数据缓冲到步骤 (b)中,和(d)对步骤(c)中的时间段经过时存储在解码缓冲器中的压缩音频数据进行解码,并将解码的音频数据存储在用于与视频数据同步的组合缓冲器中。
