【摘要】：新一代紅光高清視盤機(jī)（Next-Generation Versatile Disc，NVD）在網(wǎng)絡(luò)化背景下推出網(wǎng)絡(luò)認(rèn)證系統(tǒng)（Internet Certification System，ICS），ICS編著軟件是該系統(tǒng)的關(guān)鍵環(huán)節(jié)，提供制作節(jié)目光盤的應(yīng)用軟件環(huán)境，課題設(shè)計(jì)的編著軟件包括光盤的版權(quán)保護(hù)和導(dǎo)航制作兩部分內(nèi)容。 版權(quán)保護(hù)方面除了對(duì)節(jié)目常規(guī)加密外，設(shè)計(jì)一種以光盤和網(wǎng)絡(luò)為節(jié)目信息載體、以密鑰和部分節(jié)目?jī)?nèi)容為服務(wù)器管理對(duì)象的新型光盤版權(quán)保護(hù)技術(shù)改進(jìn)方案，抽取節(jié)目視頻編碼層中部分關(guān)鍵內(nèi)容，使得抽取后的節(jié)目無(wú)法正常播放，達(dá)到加強(qiáng)光盤版權(quán)保護(hù)的目的。版權(quán)保護(hù)方面主要包括抽取模塊和后期加密模塊，關(guān)鍵技術(shù)在于內(nèi)容抽取算法的設(shè)計(jì)和實(shí)現(xiàn)，針對(duì)目前節(jié)目光盤中H.264的視頻編碼格式，在分析編碼層數(shù)據(jù)結(jié)構(gòu)基礎(chǔ)上設(shè)計(jì)了合理的抽取算法，并使用FFmpeg開源軟件實(shí)現(xiàn)該算法。測(cè)試結(jié)果表明設(shè)計(jì)的抽取算法能夠有效地破壞視頻質(zhì)量，版權(quán)保護(hù)模塊功能正常實(shí)現(xiàn)。 導(dǎo)航文件提供播放時(shí)用戶對(duì)光盤內(nèi)容進(jìn)行操作的接口，設(shè)計(jì)了導(dǎo)航制作軟件提供可視化的圖形界面，，一是結(jié)合導(dǎo)航規(guī)范提供對(duì)導(dǎo)航的支持，如雜志廣告的支持、連網(wǎng)身份認(rèn)證和樣式模板等，二是操作功能上的完善，實(shí)現(xiàn)標(biāo)尺、參考線、圖形拖拽和動(dòng)態(tài)預(yù)覽等功能。導(dǎo)航制作方面包括坐標(biāo)定位、編輯繪制、指令集生成、動(dòng)態(tài)預(yù)覽和導(dǎo)航文件生成等模塊，關(guān)鍵技術(shù)在于結(jié)合導(dǎo)航語(yǔ)言和規(guī)范實(shí)現(xiàn)導(dǎo)航制作，以及利用有限狀態(tài)機(jī)模型生成相應(yīng)指令集，測(cè)試結(jié)果表明模塊功能完善，生成的導(dǎo)航文件放置到光盤后能夠正常實(shí)現(xiàn)導(dǎo)航功能。
[Abstract]:Next-Generation Versatile Disc (Next-Generation Versatile Disc) is the key link of the new generation red light high-definition video disk machine. It is the key link of the system to introduce the network authentication system (Certification system Versatile / ICS) under the background of network. It provides the application software environment for making program optical disk. The software includes copyright protection and navigation. In the aspect of copyright protection, in addition to the routine encryption of programs, a new type of optical disc copyright protection technology is designed, which takes optical disk and network as program information carrier and takes key and part of program content as the object of server management. Some key contents in the video coding layer are extracted, which makes the extracted programs unable to play normally, so as to enhance the copyright protection of optical discs. Copyright protection mainly includes extraction module and post-encryption module. The key technology lies in the design and implementation of content extraction algorithm. On the basis of analyzing the data structure of coding layer, a reasonable extraction algorithm is designed, and the algorithm is implemented with FFmpeg open source software. The test results show that the proposed extraction algorithm can effectively destroy the video quality and the function of copyright protection module is realized normally. The navigation file provides the interface for the user to operate on the CD content while playing, and designs the navigation making software to provide the visual graphical interface, one is to provide the navigation support, such as magazine advertisement support, in combination with the navigation specification. Network identity authentication and style template, the second is the improvement of the operation function, the realization of ruler, reference line, graphics drag-and-drop and dynamic preview and other functions. Navigation making includes coordinate positioning, editing and drawing, instruction set generation, dynamic preview and navigation file generation, etc. The key technology is to realize navigation making in combination with navigation language and specification. The model of finite state machine is used to generate the instruction set. The test results show that the function of the module is perfect and the navigation function can be realized normally after the generated navigation file is placed on the disc.
