Design And Implementation Of NVD Authoring Software Supporting The Internet Certification

Next-Generation Versatile Disc (NVD) launches Internet Certification System (ICS)under the network background. The ICS authoring software is the key part of the systemand provides the application software environment for the production of the program disc.The ICS authoring software designed in the paper includes the disc copyright protectionand navigation file production two parts.In the area of copyright protection besides conventional encryption, we put forward anew digital copyright protection improvement technology for disc, which defines the discand network as cryptograph loader, regards the key and parts of the program contents asthe server management objects. We extract some key data from the program disc, withoutthe data the player can’t play the disc normally. This can achieve the purpose ofstrengthening the copyright protection. The copyright protection software includesextraction module and encryption module, the key technology is the design andimplementation of content extraction algorithm. According to the current video is H.264format, on the analysis the coding layer data structure we design the extraction algorithmand realize it with the use of FFmpeg open-source software. The test result shows that thealgorithm can destroy the video quality effectively and the copyright protection achieves.Navigation document provides users with the operation interface, we design thenavigation production software with visual graphic interface. We support navigationcombined with its specification，such as magazine advertising support, networkingauthentication and style templates. And as application software the operation of thefunction is more perfect by achieving scale, reference line and dynamic preview, etc. Thenavigation production software includes the coordinator setting, edit operating, dynamicpreview, instruction set and navigation document generation module. The keytechnologies are supporting navigation combined with instruction language and navigationstandard, as well as using the finite state machine module to generate instruction set. Theresult shows that the functions are perfect and the navigation file can realize navigation.
