| With the rapid development of China’s video network, a large number of video website appeared and provide a wealth of video resources for users. But due to user habits of China’s video network users and the development of the industry, video website development is facing bottleneck in China and need to enrich the video source to expand audiences.This paper based on the projects which cooperate with one Network Television. The project will realize to search for the mass of video data, provide an extraction tool for the network television video to download and web video information extraction. Combined with the project requirements, analyze and design the functions and structure of the system, then form the whole system structure. Study related technologies, form the technical structure of the system, such as the actual video download address analysis, web information extraction, video stream editing and communication technologies between modules. Then realize each module of the system. This project uses spiral development mode and incremental development mode. Fully consider the requirements changes and participation of customers, use the V model test process, combined with black-box testing and white box to ensure the quality of system development.This system put into use, provide a powerful tool to expand the video source. At the same time, the system also fully considered system extensibility and system fault handling ability, for the system upgrade and maintenance version later laid a foundation. In addition, in the process of development, continue to study and solve the technology or design problems, accumulate experience for the next step in the system work and provide the way of thinking. |
