    • A method of assigning a channel identification (ID) of an audio signal by which it is possible to follow up and select the audio channel selected by a user even though a program or an audio data stream is changed in an audio/video (A/V) device for reproducing a program including a plurality of audio data streams, a method of selecting audio channels using the same, and an apparatus suitable therefor. The method of selecting the audio channels of an A/V data stream including a plurality of programs, each program including at least two kinds of audio data streams, each audio data stream including at least two sub-audio data streams which are not repeated and having a series of IDs according to a predetermined order of precedence, the method including (a) when a program is changed to another program, searching whether there is a sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed, in the changed program, and (b) when it is determined that there is the sub-audio data stream having a channel ID which is the same as the channel ID assigned to the sub-audio data stream of the program which was being reproduced before the program was changed in the step (a), selecting the sub-audio data stream. According to the method of selecting the audio channels, it is possible to follow up a voice mode selected by a user (maintain the previously selected audio channel) although a program or an audio data stream is changed.
    • 一种分配音频信号的信道标识(ID)的方法,通过该信道标识(ID)可以跟踪并选择由用户选择的音频信道,即使音频/视频中的节目或音频数据流被改变(A / V)装置,用于再现包括多个音频数据流的节目,选择使用该音频数据流的音频频道的方法,以及适用于其的装置。 选择包括多个节目的A / V数据流的音频信道的方法,每个节目包括至少两种音频数据流,每个音频数据流包括不重复的至少两个子音频数据流,以及 具有根据预定优先顺序的一系列ID,所述方法包括(a)当程序改变为另一程序时,搜索是否存在具有与频道ID相同的频道ID的子音频数据流 在改变的节目中被分配给正在再现的节目的子音频数据流,以及(b)当确定存在具有频道ID的子音频数据流时, 与在步骤(a)中在程序改变之前正在再现的节目的子音频数据流分配的频道ID相同,选择子音频数据流。 根据选择音频通道的方法,尽管程序或音频数据流被改变,仍然可以追踪用户选择的语音模式(保持先前选择的音频通道)。
