AN OPTICAL DISC SOLUTION FOR DIGITAL VIDEO STORAGE

The advent of digital video systems for capturing, manipulating, and t ransmitting digitized images has created challenges for existing techn ologies because very high data volumes and data transfer rates are nec essary to reproduce high-quality video images. While digital data comp ression methods have made it possible to consider using digital video for everyday applications, there is still a challenge when a significa nt amount of digital video needs to be stored for future use. This pap er describes a storage method using an optical disc technology that pr omises a convenient low-cost solution to the digital video storage pro blem. This method allows permanent storage of as much as four hours of broadcast-quality digital video or one hour of digital HDTV on a sing le side of a 12-in. recordable disc. This technology will be available very soon and is expected to have a major impact on many applications of digital video.
