Film has been used widely since Auguste and Louis Lumiere hold the first private screening in 1895. Star Wars Episode II: Attack of the Clones directed by George Lucas released on May 16, was the first motion picture both to be shot completely on a high definition digital 24-frame system and to be projected by digital projectors. Its success showed us that the digital cinema era is imminent. Digital Cinema will enable the studios and movie distributors to low the expenses of making and delivering film prints and dissemination of it can put the entire digital cinema ecosystem in great jeopardy. Therefore DRM and other security policies are used for digital cinema content protection. In this paper it will be discussed how the digital cinema platform can package (encooe & encrypt), transport, and project the digital cinema contents safely.

Our study measures the Digital Life Index (DLI) of baby boomers by considering the utilization of digital devices in their everyday life. The study was conducted by implementing the following three-step approach: (1) development of survey questions and data collection; (2) build Digital Life Index (DLI) model and lastly; (3) empirical analysis using the Digital Life Index (DLI). In the first stage in order to develop the survey questions to measure the digital index, two surveys were conducted. For the first preliminary survey, it was done based on the existing literatures which enabled this investigation through FGI analysis involving real professionals. The second survey was conducted by commissioning a specialized external firm. In this survey, a total of 400 data was collected to verify the validity and objectivity of the data sample. The data gathered through the survey questions was used to develop the digital index. Firstly, the appropriate factors were extracted by conducting factor analysis. This factor analysis validates and verifies the factors which are appropriate in measuring Digital Life Index (DLI). The derived factors are broadly divided into five main factors. The first factor describes the possession, purchase and use of digital device (x1). Meanwhile, the second factor describes the digital device's software (x2) and the third factor describes the participation in utilizing digital device (x3). The fourth factor describes the utilization of digital device in human personal relationship (x4) and lastly, the fifth factor describes the effect of digital device in everyday life and work environment (x5). Secondly, the digital index model was developed. The variables to represent the Digital Life Index (DLI) are ${\chi}1t,{\chi}2t,{\chi}3t,{\chi}4t$ and ${\chi}5t$. Furthermore, as experience in using the digital index grows overtime, the growth can be represented by the "S" shape. Based on the results, Digital Life Index(DLI) is distributed with the highest point at 90.3 and the lowest point at 25.9.

Digital technology has become a new economic and social force, reshaping traditional business models, strategies, structures, and processes. This is a challenge for human capital to develop continuously in this dynamic era; one of the solutions is digital entrepreneurship. Digital entrepreneurship focuses on creating new ventures and transforming existing businesses by developing novel digital technologies or novel usage. Further, digital technology has also enabled the growth of the sharing economy, linking owners and users, and disrupting the previous dualism of businesses and customers. This paper provides a novel contribution regarding the emerging concept of Digital Entrepreneurship. Based on a qualitative literature review and interview with university staff, lecturers, and students in four large public and private universities in West Java and DIY Province, an interpretative framework for Digital Entrepreneurship has been proposed, which comprises of the following components: motivation (the rationale for the adoption of digital technology for academic entrepreneurship), stakeholders (the stakeholders involved through digital technology to achieve the academic entrepreneurship goal), process (the processes of academic entrepreneurship supported by digital technologies), and business form (the emerging forms of digital academic entrepreneurship). This research also shows several alternative government policies to improve digital entrepreneurship in the academic environment.
