    • An encoding controlling apparatus is disclosed which includes: offset holding means for holding an offset equivalent to a time period by which to start encoding an audio signal earlier than a video signal upon recording of a chapter; recording mode determining means for determining whether a seamless connection is possible between the preceding chapter and the following chapter in order to set an initial value of the offset depending on an outcome of the determination; offset updating means for updating the offset in keeping with progress in encoding the video signal and the audio signal; and recording controlling means for giving an instruction either to start or to stop the encoding of the video signal and the audio signal in accordance with the offset. The inventive apparatus controls the encoding process in keeping with the offset between the audio and video signals, thereby achieving seamless connection between chapters without incurring discrepancies between the video and audio signals.
    • 一种编码控制装置,包括:偏移保持装置,用于在记录章节时保持与视频信号之前的音频信号开始编码的时间段相当的偏移量; 记录模式确定装置,用于确定前一章和下一章之间是否可以进行无缝连接,以便根据确定的结果设置偏移的初始值; 偏移更新装置,用于根据编码视频信号和音频信号的进度来更新偏移; 以及记录控制装置,用于根据偏移量给出开始或停止视频信号和音频信号的编码的指令。 本发明的设备控制编码过程以保持音频和视频信号之间的偏移,从而实现各章之间的无缝连接,而不会导致视频和音频信号之间的差异。
