A video audio recording apparatus comprising: a record means which records an encoded stream of a video and an audio; a stream hold means which temporarily stores the encoded stream before recording the encoded stream in the record means; an image-change-point detection means which detects a scene change from video data of the encoded stream stored in the stream hold means; a silence detection means which detects a silence and a time length of the silence from an audio signal; a temporary storage means which temporarily holds the scene change information detected by the image-change-point detection means and the silence information detected by the silence detection means; a changeover-point detection means which detects a changeover-point, at which both the scene change and the silence occur at the same time from the scene change information and the silence information held by the temporary storage means; a CM-broadcast-period determination means which judges a particular period of time when two or more potential CMs are successively detected as a CM broadcast period, each potential CM being an interval between two successive changeover-points detected by the changeover-point detection means which coincides with one of a plurality of predetermined CM reference times, wherein: a CM-broadcast-period-information record means which records time information of the CM broadcast period determined by the CM-broadcast-period determination means.
