Embodiment 1

[0117] Fig. 1 is a block diagram showing the structure of a music data editing apparatus according to Embodiment 1 of the present invention. To the music data editing device of Embodiment 1, video and audio data formed by editing video and audio data recorded with a digital video camera, etc., with a desired length on the time axis is input. video and audio data. The music data editing device of the first embodiment is a device that edits the music selected by the user as BGM (background music) with an appropriate length on the time axis corresponding to the input video and audio data, and adds it to the video and audio data. .

[0118] As shown in Figure 1, the music data editing device of embodiment 1 has: audiovisual data input part 1, its input is processed into the videoaudio data of desired time by the user; Videoaudio data output part 2, it will Image data and sound data are divided and output; Editing section 3 stores a plurality of music data that is pre-processed a...

Embodiment 2

[0162] Next, a music data editing device and a music data editing method according to Embodiment 2 of the present invention will be described. The music data editing method includes a music data recording method and a music data playback method.

[0163] The structure of the music data editing apparatus of Embodiment 2 of the present invention is the same as that of the music data editing apparatus of Embodiment 1 shown in FIG. 1 described above. The second embodiment differs from the first embodiment in the editing method of the music data, and also in the recording method of the music data and the playback method of the music data. The music data editing device of embodiment 2 also inputs the video and audio data edited into video and audio data with a desired length on the time axis by using, for example, a digital video camera, etc., and uses the music selected by the user as the BGM ( Background music) is edited to have an appropriate length on the time axis and added to...

Abstract

There are provided a music composition data edition device and a music composition data edition method in which music composition data is divided by a temporal axis direction into at least main data, ending data, and connecting data. In order to match the start point and the end point of reproduction time of video / audio data inputted, the reproduction time of the main data is calculated in bar unit and the main data is reproduced in the reproduction time calculated. Subsequently, the connecting data and the ending data are successively reproduced.

Description

technical field [0001] The present invention relates to a music data editing device and a music data editing method used in the editing of music data which edits the playback time of general music corresponding to video and audio data and adds it to the video and audio data, and relates to music data editing. recording and playback of song data in the Background technique [0002] In recent years, as the performance of personal computers and their peripheral devices has improved, editing of video and audio data recorded using digital cameras and the like has become easier. Moreover, more and more people are eager to appreciate it as a "work" by adding music as BGM (background music) to the edited audiovisual data. However, the length on the time axis of video and audio data captured by a digital camera or the like, that is, playback time, varies greatly depending on the respective video and audio data. Also, when the user wants to add favorite music as BGM to such video an...
