Video synthesizing apparatus and program

摘要

The invention provides data for display on the display area for a child frame when the child frame is synthesized and displayed on the parent frame in picture-in-picture playback in order to give the displayed area of the child frame in conformity with the video content in the parent frame, as well as providing a video display apparatus etc. for displaying the child frame at an appropriate displayed position using the data for display. A video display apparatus 1 includes: decoders 101 and 103 for decoding two sets of video data; a synthesizer 105 for synthesizing the decoded videos to output; an input unit 108 for commanding display/non-display of the child frame; a processing controller 109 for controlling the operations of decoders 101 and 103 in accordance with the command; and a position designator 110 which receives the command and the data for display, and time information and designates the displayed position of the child frame to the synthesizer 105. The position designator 110 determines the displayed position of the child-frame video in accordance with displayable time information of the child-frame video and information on the displayed area or displayable area depending on time, included in the data for display.

主权项

1. A non-transitory computer readable medium containing instructions executed by a processor, the non-transitory computer readable medium recording a first video, a second video, and metadata for displaying the first video and the second video by superimposing the second video over the first video in a picture-in-picture format, wherein
the second video is provided in such a manner that display or non-display of the second video is changed at an arbitrary point of time within a displayable period designated in the first video, the metadata is data that includes: time information representing a dedicated second playback time in the second video differing from a first playback time in the first video, and displayed area information that represents a displayed area of the second video in the first video at the time when the second video is changed to displaying, imparted in correspondence with the second playback time in the second video, and wherein video data contained in the non-transitory computer readable medium is reproduced by a video synthesizing apparatus which reads out the first video, the second video and the metadata, designates a displayed position inside the first video based on the metadata when the second video is displayed at an arbitrary point of time, and synthesizes the second video over the displayed position, wherein the metadata manages the second playback time at which the displayed area of the second video is changed to a different position in the first video.
