In November 2015, NHK will launch a fully auto-generated program outline system in our archive database.
Files of news and other programs are transmitted from the play-out server to the archive server after broadcast. At the same time, all the metadata including copyright information is sent to the archive information system. This system automatically generates a program outline table containing descriptions of sequences and shots, narration scripts, subtitles, copyright information, and conditions of use for each program. Since the system can recognize breaks of each shot automatically, images of the first frame of each shot are shown in the thumbnail column. Narration script is to be taken from the closed-captioning service. This new system will dramatically enhance functionality of the database.
This outline table is very useful for producers as they can easily grasp the content of each program by browsing. Every word in the script can be retrieved by the search engine in the database. By clicking a thumbnail, users can watch a reference video. By clicking a checkbox, users can request a copy of the sequences or shots. They can also access detailed copyright information of each shot or sequence such as payments, copied contract, and trouble reports. This complete metadata management system will simplify the procedure for reuse of the content for productions, online services and distribution. We hope that it will promote utilization of stored programs and eventually help reduce location expenses.
