The Concept Of Digital Rights Management In Iptv Application Research

With the gradually popularization of national policy of three nets fusion, broadcasting andtelecommunications industry in the process of fusion are trying to occupy the initiative throughnew value-added application mode. Traditional basic communication industry under thestimulus of a growing network of industry, the need to develop new business and looking for anew business operation mode; New development of streaming media technology and the furtherpopularization of the broadband users eager to reduce costs at the same time enjoy theconvenient life more smooth picture, a higher level of audio and video, more personalized TVservice. Both industry attempts to based on the existing resources itself, make up the weakness,try to find a new source of income, IPTV so expectation is a kind of business. Newdevelopment is always accompanied by the birth of the theory and the innovation of newtechnologies, IPTV in the development process of how to grasp the opportunity to dissolvedangerous, also has the certain research significance and value.According to the purpose of this study and content, the literature analysis, case analysis andinterview with related people and standard methods of design, on the basis of mainly thefollowing several aspects work:（1）IPTV successful mode as well as industry development at home and abroad. In thefirst stage stage research papers, the author through the literature collection, data analysis andinterview with professionals, accumulated IPTV DRM technology and relevant news in avariety of ways, such as establishing the DRM standard mode to set the desired basic theory,combined with domestic and foreign research status related to the theory analysis, firstdetermine the IPTV business value connotation and industry chain structure, domestic andinternational successful IPTV operation mode analysis of previous research strategy, researchprovides the theoretical support for DRM application.（2）Existing digital rights management technology and the standard model. The firstphase of the research and analysis for the development of IPTV industry in China is one of keyfactors for digital copyright protection and management of the digital rights to those who live inIPTV world in the future has become the accepted rules of the game. However the scientific nature of the existing domestic copyright legislation about lack of advancing with The Times,especially after China’s accession to the WTO, many related copyright terms will be very baddigital copyright protection in China. Existing DRM technology to provide operators such asMicrosoft RMS, Apple Quicktime, RealNetwork RealPlayer have DRM technologies offers avariety of standard according to their demand, further enhance the value of the copyright. A lotof manpower and resources into the DRM related technology research, including the familiardigital encryption technology and digital watermarking technology.（3）Expansibility authorized DRM standard model content set. In existing DRMtechnology and standards under the premise of existence, into the modern enterprisemanagement system and the communication of the interactive theory, the connotation of theDRM standard extends to the public infrastructure, makes IPTV DRM standard no longerpurely on technology as the core, but pay more attention to respect user plays an important partin the whole industry chain, from the development of IPTV industry safe, efficient service andtrade fair, the content of the interests of balanced and integrated talent cultivation and so onenriching the connotation of the DRM standard.（4）The DRM standard mode. Complex backgrounds, different industry, multipletechnical standard and so on all make IPTV industry in the process of development faces theneed to work together. Cooperation is established on the basis of interest balance and trade fair,and how to protect the reasonable interests of the industry department (rather than a legitimateinterests) has become the main content of the digital rights management. Apple, according tothe theory of music operations against DRM standard model has a certain operation in realitymeaning and theoretical basis, is likely to become the future China IPTV industry developmentprocess for the public interests and public welfare services of some special case.The author tried to design with Chinese characteristics through systematic research of IPTVindustry standard of copyright protection in order to realize the balance of interests betweenindustry sectors, and reduce the conflict between content and user personal information safety,the development of IPTV industry create a fair and sustainable, dynamic operating environmentas a whole. Integrating traditional DRM technology to analysis in economics, management,sociology, communication studies, and law and other related concept, design authorized DRM standard extensibility, the DRM content extends to the public service infrastructureconstruction, to adapt to the unique operating characteristics and development trends of IPTVindustry. Moreover, DRM standard extensibility authorized users’ personal information safetycoefficient through multilateral agreement that allows users in the selection of personalized,interactive TV and surf the Internet, online games and other value-added services in themaximum limit to protect their privacy, satisfy their wish to freedom of choice.Due to the time of the author’s research and academic ability is limited, especially in IPTVindustry operation and the lack of the first-hand information, though authorized DRM standardextensibility model can reflect the author intention and conception for the future developmentof IPTV industry, but only has carried on the preliminary theory construction, and consulting totry, the details still exist deficiencies, the future research work will continue to revolve aroundthe IPTV industry extensible authorization DRM standard carry on design of operability.
