Video Information Recording and Outputting Method, Recording Media and Recording and Playback System
摘要:
It is a task of this invention to create a novel system (ubiquitous movie) that brings benefits to both a copyright holder of video information such as movies and general consumers who want to enjoy viewing the video information.As for high image quality video information that the copyright holder wants to keep in a copy prohibited condition or the like, a copyright control such as copy prohibited condition is performed as is done with DVDs. In addition to the high image quality video information, a medium is recorded with another piece of video information whose image quality is limited to less than half the resolution of the high image quality video information, at which level the copyright holder can afford to permit the video information to be copied. This low image quality video information is attached with copyright protection information allowing copy, move and download operations as it is recorded in the medium. From this video information-recorded medium, the video information with the limited resolution is read out and recorded in a small medium that is easy to handle outdoors. The small medium containing the video information with the limited resolution is played in a video player that has a small display showing the played back video information.
