    Abstract: An audio reproducing method for quickly and correctly extracting extra data, including: receiving a data stream including the extra data including an end marker disposed immediately before main data and data length information, which is length information of the extra data, disposed immediately before the end marker; checking the presence/absence of the end marker; and if the end marker exists, extracting the extra data by using the data length information.

    Abstract translation: 一种用于快速且正确地提取额外数据的音频再现方法,包括:接收包括紧邻主数据之前设置的结束标记的附加数据的数据流和作为紧邻结束之前设置的额外数据的长度信息的数据长度信息 标记 检查结束标记的存在/不存在; 并且如果存在结束标记,则通过使用数据长度信息来提取额外的数据。
