Abstract


The research papers from independent research and development of enterprises,mainly in the upcoming digital film industry should change the development of digital cinema playback device. The Hollywood studios occupy a dominant position in the global film industry, the number of film equipment development has to be followed by Hollywood producers of quality screening equipment, technology, for copyright protection. To promote the development of digital cinema 7 major Hollywood studios set up DCI.igital Cinema projection equipment co-developed the technical requirements. And officially released in 2005, "DCI digital cinema technical specifications", the project is in accordance with the technical specifications for digital cinema playback servers of the research and development. Device development involves wavelet-based JPEG2000 image compression algorithm 2048* 1080 resolution 250Mbs stream real-time decoding, AES-128bit high real-time data stream encryption and decryption, Audio and video watermarking technology implementation and overlay, card protection and key features anti-demolition. Completion of the project is divided into four stages, namely:First, needs analysis and program design; Second, research and development phase of the extension; third, system integration, testing and perfecting stage; four, testing, trial production and delivery stages. The equipment will be finished basic development needs to be sent to the Hollywood film studio in the tests in order to ensure the Hollywood studios authorized to broadcast of imported films. After two years of the results of the project has already been approved by the Hollywood professional bodies and inputs to the actual market operation, has sold more than 600 installation of the project is also a key project of the Beijing Municipal Science and Technology Commission, and the successful conclusion.
