摘要： In a method and apparatus for generating musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit and a lyric storage unit separate from the audio storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The lyric data include encoded text data and timing information. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium. The encoded text data and timing information retrieved from the recording medium are decoded to obtain decoded data, and bitmap data are then generated from the decoded data. The bitmap data are synchronized with the audio music data retrieved from the recording medium in accordance with the timing information. The audio music data retrieved from the recording medium are provided to a sound card to obtain an audio output. The bitmap data are provided to a VGA card to obtain a video signal.
摘要翻译：在用于产生与音乐节目相对应的音乐伴奏信号的方法和装置中，提供了一种具有与音频存储单元分开的音频存储单元和歌词储存单元的记录介质。音频存储单元和歌词存储单元分别具有多个音频音乐数据和与存储在其中的多个音乐节目对应的多个歌词数据。歌词数据包括编码的文本数据和定时信息。在操作中，从记录介质中检索对应于所选音乐节目中的音乐节目的音乐音乐数据和歌词数据。从记录介质中检索出的编码文本数据和定时信息被解码以获得解码数据，然后从解码数据生成位图数据。位图数据与根据定时信息从记录介质检索的音频音乐数据同步。将从记录介质检索的音频音乐数据提供给声卡以获得音频输出。将位图数据提供给VGA卡以获得视频信号。

摘要： In a method and apparatus for generating audio-visual musical accompaniment signals corresponding to a musical program, there is provided a recording medium which has an audio storage unit, a lyric storage unit and a video storage unit separate from the audio storage unit and the lyric storage unit. The audio storage unit and the lyric storage unit respectively have a plurality of audio music data and a plurality of lyric data corresponding to a plurality of the musical programs stored therein. The video storage unit has a plurality of video segments to be commonly shared by the plurality of the musical programs stored therein. In operation, the audio music data and the lyric data corresponding to a selected one of the musical programs are retrieved from the recording medium, while at least a section of the video segments are retrieved from the recording medium in an order. The audio music data retrieved from the recording medium is converted into an audio output, and the lyric data and the sections of the video segments retrieved from the recording medium are combined to obtain a video output. The audio and video outputs constitute the musical accompaniment signals corresponding to the selected one of the musical programs.
摘要翻译：在一种用于产生与音乐节目相对应的音像伴奏信号的方法和装置中，提供了一种记录媒体，它具有与音频存储单元和歌词分开的音频存储单元，歌词储存单元和视频存储单元存储单元。音频存储单元和歌词存储单元分别具有多个音频音乐数据和与存储在其中的多个音乐节目对应的多个歌词数据。视频存储单元具有由存储在其中的多个音乐节目共同共享的多个视频片段。在操作中，从记录介质中检索对应于所选音乐节目中的一个音乐节目的音乐音乐数据和歌词数据，同时依次从记录介质中检索至少一部分视频段。将从记录介质检索的音乐数据转换为音频输出，并将歌唱数据和从记录介质检索的视频段的部分组合起来以获得视频输出。音频和视频输出构成对应于所选择的一个音乐节目的音乐伴奏信号。
