Content Creation Utilizing Large-Scale Archive with Content ID and Original Time Code

Stored video data in the large-scale archive will be used primarily for content creation and secondarily for content distribution. In both cases the protection of intellectual property is an indispensable issue. A good solution of this issue may be to adopt Content ID (identification) being promoted by the Content ID Forum. Content ID is a unique identifier to realize some benefits of materials (or contents) distribution. A part of the Content ID will be watermarked on video itself. In the Content ID, we propose to include an Original Time Code that is a time code from an original tape (or cassette). Through the network, how to get the materials for preview is another issue. We chose MPEG-4 as the compression technology. The first of choosing reasons is the lower-band transmission capability. Second is that the Content ID could be easily carried with MPEG-4 stream. Remote editing terminal outputs an Edit Decision List (EDL) to an editing studio for high quality editing. In this process the EDL is created with the Original Time Code. On the other hand the local Time Code might be used in the editing studio. In such case some Time Code conversion is needed to execute the EDL.
