<p>A video synthesizing apparatus synthesizes a first video and a second video; a displayable period of the second video is designated within a playback time of the first video, and a playback of the second video is started at an arbitrary point of time within the displayable period; is ended when the second video is completed or a playback time of the second video is past the displayable period; and is switchable between display and non-display at an arbitrary point of time during playing. The apparatus comprises
a designating means which
receives data for display including:
time information representing time in the first video, designated in a range of all time within the displayable period; and
displayed area information representing a displayed position when the second video is displayed at the time, and
designates a displayed position when the second video is displayed at an arbitrary point of time, based on the data for display, and
a synthesizing means which synthesizes the second video over the displayed position in the first video, designated by the designating means. The invention also includes a computer program which makes a computer function as the video synthesizing apparatus, and a recording medium recorded with the first and second video, display data for synthesizing the second video over the first video.</p> |
