The Design And Implementation Of Carnival Broadband Theater System

With the rapid development of the computer technology, network communication technology, multimedia technology, Internet users and broadband users are growing rapidly, and network transmission with their unique fast, efficient and convenient way have impacted on the traditional way of learning and life. Online theater as a representative of streaming media technology has been much rapid development. The multimedia contents which people getting from the Internet are becoming more and more exciting, the user communities are rapidly expanding. A set of broadband theater system which the Internet broadband operators how to successfully seize the opportunity to develop is an urgent problem.From the development situation of the entire market,the current online video market is small, The service providers have no existing content, while the real holders—SP of content resources take a wait-and-see attitude, which makes the current situation of China's online video market embarrassing. The normative development of online video market needs the government to strengthen supervision, specify responsibilities and regulate market order.Due to the lack of norms and constraints, some of the illegal and non-formal sites intercept huge profits, disrupt the development of the market, combat and influence the confidence of developing formal broadband video market.From a competition point of view,there are about 20 formal and 50 informal online video operators. Because of the copyright, marketing problems, the online video income of the formal operators is less than 30% of revenue share.,while the income of the non-formal operators is more than 70%.There is still not well resolved of the film and television content, update rate etc. Besides, there are some problems of the non-formal private sites and regulation. There still needs 1 - 2 years to develop online video marketIn the background, the Chinese online video market competition of the regular telecom operators is gradually formed, the pace of opening up is gradually increased, including major telecom operators abroad to enhance core competitiveness, form a solid customer base and enhance the value UP to meet the demand for broadband multimedia development. China Unicom, China Telecom, China Railcom and other domestic telecommunications operators are building multimedia systems of their own broadband theater to discourage private non-formal monopoly. Most of the front-line broadband theater that home bright,style new,manipulation simple,brand guarantee and more favored by the users. Up to now investments in the development and maintenance of broadband multimedia systems have accounted for 20% to 25% on the total investment, and the proportion are increasing every year.In order to adapt to market demand,China Unicom have designed and developped the Carnival broadband theater system by sophisticated market researching, building framework of front pages and the database table structure, testing requirements for 9 months.The system has good stability, flexible scalability, definite system architecture, user-friendly appearance, and supports concurrent streaming capability. The main function points include the front part of the dynamic-type film and video information distribution, information search and a variety method of view. Users may quickly and easily find the information. The download rankings and displaying view level are provided by the Carnival broadband theater. The level of membership can be judged by the system,which is determined whether to implement online viewing, upload videos, download videos and other operations. The background partition are used by managers, including member information management, video content management and video data management.The three modules have the function of adding, deleting video information, processing and freezing the number of registered user rights, changing membership-level, deleting the function of member information.The J2EE technology architecture specifications which carnival broadband theater system uses, not only save development costs, but also meet the applications of high availability, reliability and scalability. The carnival broadband theater system has applied JSP technology at the front visual desk ,and linked through JDBC-ODBC bridge technology and database ,then embedded PL / SQL statements to complete the operation of the database. Thus has realized the system requirements including user registration, video rankings, information search, upload, download and membership management, directory management,etc.Now the carnival theater system has accessed to trial run.All the function points within the system have worked properly, the system is stable.According to feedback of the testers and users, the system video is currently updating faster, the picture quality of online video is clear and smooth,registrating and inquirying relative films are relatively simple,maintaining the system is easy to use,costs low, and the interface is easy to understand,Through the success of carnival broadband on-line theater system, the system not only restrains the development of some illegal online video site,but also improves the core competitiveness of the market, Besides,the system retains and attracts the majority of broadband users, enhances the UP value and brings considerable economic benefits for the company. From long-term interests,the related technology and experience are helpful to the future of broadband broadcasting, the development of broadband TV and other broadband value-added business have laid a good foundation for the upcoming triple-play.
