The NCHC Wins 7th Golden Penguin Award!2009/12/21
The MonitorGrid project, developed by the NCHC’s Grid Application Team, is a real-time video processing and multicast system based on the NCHC-developed networking and real-time streaming techniques and developed using free software. This application research recently won the Golden Penguin Award for R&D Innovation at the 7th Linux Golden Penguin Award, hosted by the Industry Development Bureau of the Ministry of Economic Affairs, Taiwan.
Most surveillance devices on the market today are built on a single host, In other words, the system’s surveillance software only supports a specific image capturing board and video camera type, and provides only single resolution and a few image streams formatted for viewing. On the other hand, the NCHC-developed MonitorGrid is made up of both a system and a device that are independent of each other, but also work together as a real-time multimedia service platform. On the image capturing end, the system can receive and process signals from various types of image capturing devices (e.g.: DV, HDV, Webcam, CCD, etc.), compress image size automatically, and convert it into various image resolutions and formats for far-end or local-end users to view real-time.
The system architecture utilizes a distributed design in that the processing units are serial connected in a Loose Coupling manner with the individual units being independent of each other. When there are fewer monitoring sites resulting in a smaller load to the system, three units can be built on a single computer. On the other hand, when there are too many monitoring sites for one computer to handle, three units can be separately built on three separate computers. Additionally, these three computers can be any three nodes on the network. As a result, device resources are utilized in the most efficiently.
(1) Supports multiple capture media and multi-streaming format consistent interface design.(2) Utilizes the Multi-server Loose Coupling structure.(3) Able to perform real-time video streaming processing and utilizes slice storage Round-Robin Queue structural design.(4) When monitoring images, two individual still images are automatically saved and achieved in order to facilitate queries.(5) Real-time images can be viewed from any device with Internet access.(6) When building this platform among multiple computers, different host specifications and operation systems can be installed and interconnected and process different issues.(7) Due to its distributed architecture, there is no limit to the number of video cameras that the platform can support.
In today’s modern technology-based society, the Internet has been applied to almost all aspects of daily life. The winning of the Linux Golden Penguin Award not only acknowledges the NCHC’s achievements in developing free software, but also its ongoing ability to develop innovative applications.
