The Design And Application Of Low-cost High-definition Video Educational Resources Production System

2008 Beijing Olympic Games broadcast to the world by high-definition TV signals, which greatly promote high-definition video production and development of China. The high-definition has become the trend of video production. High-definition video with a high-quality video images and realistic surround sound audio, has more video expressive, vivid audio and the ability to restore a more realistic colors. Surround sound can create a real sound environment, and Create a sound space. The characteristics of High-definition video and sound will enable high-definition video educational resources to get more attention, In favor of creating learning environment and expression teaching content. At the same time, solve the problem of low quality of video educational resources in health care, art painting, film and television shows, Scene Simulation and other special areas.This paper research the construction and application of high-definition video educational resources production system,by the research methods of combining the theory and practice, using the relevant theory to guide practice, summarizing experience in practice, to seek a solution of the problem. First of all,papers focused on system design of the low-cost high-definition video educational resources, proposed principle of the production system design, completed the establishment of production system. Followed, low-cost high-definition video educational resources production system became a platform to complete the production of high-definition video educational resources and high-definition video practice educational resources media asset management practice. In part of the production of high-definition video educational resources, the paper focus on the difference of high-definition and standard-definition video production, in which the surround sound and high-definition color adjustment are the part of the technical highlights of this. in part of the high-definition video Educational resources media asset management practices, the high-definition video Educational resources media asset management in this paper based on the idea of media asset management in TV. use the capabilities of Avid Xpress Pro HD software media management, with low-cost high-definition video educational resources production system hardware platform, to build digital media asset management system, management of media assets, improve the management of high-definition video educational resources, to facilitate the resources query, retrieval, processing and reuse.
